WARNING!  
A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD  
TO OBTAIN POSITION INFORMATION.  
CAUTION  
When showing navigation data to a position (waypoint), a GPS unit will show  
the shortest, most direct path to the waypoint. It provides navigation data to the  
waypoint regardless of obstructions. Therefore, the prudent navigator will not  
only take advantage of all available navigation tools when traveling to a way-  
point, but will also visually check to make sure a clear, safe path to the waypoint  
is always available.  
WARNING!  
When a GPS unit is used in a vehicle, the vehicle operator is solely re-  
sponsible for operating the vehicle in a safe manner. Vehicle operators  
must maintain full surveillance of all pertinent driving, boating or fly-  
ing conditions at all times. An accident or collision resulting in damage  
to property, personal injury or death could occur if the operator of a  
GPS-equipped vehicle fails to pay full attention to travel conditions and  
vehicle operation while the vehicle is in motion.

Section 1: Read Me First!  
How this manual can get you out on the road, fast!  
Welcome to the exciting world of digital sonar and GPS! We know  
you're anxious to begin navigating and finding fish, but we have a favor  
to ask. Before you grab the unit and begin installing it, please give us a  
moment or two to explain how our manual can help you get the best  
performance from your compact, wide-screen, combination fish finder  
and mapping GPS receiver.  
First, we want to thank you for buying a Lowrance sonar/GPS unit.  
Whether you're a first time user or a professional fisherman, you'll dis-  
cover that your unit is easy to use, yet capable of handling demanding  
navigation and sonar tasks. When you team your unit with our custom  
mapping software MapCreate6, you have an incredible combination.  
You won't find another combination GPS and sonar unit with this much  
power and this many features for this price!  
Our goal for this book is to get you on the water fast, with a minimum  
of fuss. Like you, we'd rather spend more time boating or fishing and  
less time reading the manual!  
So, we designed our book so that you don't have to read the whole thing  
from front to back for the information you want. At the start (or end) of  
each segment, we'll tell you what content is coming up next. If it's a  
concept you're already familiar with, we'll show you how and where to  
skip ahead for the next important topic. We've also made it easy to look  
up any tips you may need from time to time. Here's how:  
The manual is organized into 10 sections. This first section is an intro-  
duction to the LMS-480 or LMS-480DF, sonar and GPS. It tells you the  
basics you need to know before you can make the unit look around and  
tell you where you are, or look below the surface to find some fish.  
Section 2 will help you install your unit, the transducer and the GPS  
antenna module. We'll show you how to get the MultiMedia Card  
(MMC) correctly installed inside the unit. We'll also tell you about some  
of the available accessories.  
Section 3 covers Basic Sonar Operation. It will show you how easy it is  
to run your LMS-480 series sonar, right out of the box. This section fea-  
tures a one-page Sonar Quick Reference. (If you've already jumped  
ahead and figured out how to install the unit yourself, and you  
just can't wait any longer, turn to the Quick Reference on page  
51 and head for the water with your LMS-480!)

After you've gained some experience with your sonar, you'll want to  
check out Section 4, which discusses more advanced Sonar Options and  
Other Features.  
When you come to a sonar menu command on the LMS-480 screen, you can  
look it up in the manual by skimming over the table of contents, just flip-  
ping through Section 3 or scanning through the sonar options in Section 4.  
If you're having difficulty with your sonar, you can find an answer to  
the most common problems in Section 5, Sonar Troubleshooting.  
The manual switches from sonar to navigation in Section 6, which in-  
troduces you to Basic GPS Operations. This section features a one-  
page GPS Quick Reference on page 112.  
Section 6 contains short, easy-to-scan GPS lessons that follow one an-  
other in chronological order. They're all you'll need to know to find your  
way on the water quickly.  
After you've learned the basics (or if you already have some GPS expe-  
rience), you may want to try out some of LMS-480's many advanced  
navigation features. That brings us to Section 7, Advanced GPS Opera-  
tions. This section contains the rest of LMS-480's GPS command func-  
tions, organized in alphabetical order.  
When you come to a GPS menu command on the LMS-480 screen, you  
can look it up in the manual by skimming over the table of contents,  
just flipping through Section 6 or scanning through the command por-  
tion of Section 7.  
LMS-480 is ready to use right out of the box, but you can fine tune and  
customize it's operation with dozens of options. Since sonar is the unit's  
key feature, we put the main sonar options in Section 4. Some options,  
such as screen brightness settings, affect both sonar and GPS opera-  
tions. We describe how to use those common options along with GPS  
options in Section 8, System Setup and GPS Setup Options. Section 8 is  
organized in alphabetical order.  
In Section 9, we go into more detail on one of LMS-480's most remarkable  
GPS capabilities — Searching. We'll introduce a search example in the Ba-  
sic GPS Operation section, but there are so many map items you can  
search for, we had to give this function it's own section in the manual! For  
example, did you know LMS-480 can look up business phone numbers,  
functioning as a virtual Yellow Pages? We’ll show you how in Section 9.  
Finally, in Section 10, we offer Supplemental Material, including a list  
of the GPS datums used, warranties and customer service information.

NOTICE!  
The storage temperature range for your unit is from -4 degrees to +167  
degrees Fahrenheit (-20 degrees to +75 degrees Celsius). Extended stor-  
age in temperatures higher or lower than specified will damage the liq-  
uid crystal display in your unit. This type of damage is not covered by  
the warranty. For more information, contact the factory's Customer  
Service Department; phone numbers are listed on the last page.  
How LMS-480 Sonar Works  
Sonar has been around since the 1940s, so if you already know how it  
works, skip down to read about the relatively new technology of GPS.  
But, if you've never owned a sonar fish finder, this segment will tell you  
the under water basics.  
Sonar is an abbreviation for SOund NAvigation and Ranging, a technol-  
ogy developed during World War II for tracking enemy submarines.  
(Lowrance developed the world's first transistorized sportfishing sonar in  
1957.) A sonar consists of a transmitter, transducer, receiver and dis-  
play. In simple terms, here's how it finds the bottom, or the fish:  
5
Download from Www.Somanuals.com. All Manuals Search And Download.  
The transmitter emits an electrical impulse, which the transducer con-  
verts into a sound wave and sends into the water. (The sound frequency  
can't be heard by humans or fish.) The sound wave strikes an object  
(fish, structure, bottom) and bounces back to the transducer, which  
converts the sound back into an electrical signal.  
The receiver amplifies this return signal, or echo, and sends it to the  
display, where an image of the object appears on the scrolling sonar  
chart. The sonar's microprocessor calculates the time lapse between the  
transmitted signal and echo return to determine the distance to the  
object. The whole process repeats itself several times each second.  
Your LMS-480 can record a log of the sonar signals that scroll across  
the screen and save them to the MMC memory card. (These recordings  
are also called sonar charts or sonar graphs.) You can replay this sonar  
log in the unit using the Sonar Simulator function, or play it back on a  
personal computer using our free Sonar Viewer. The viewer is available  
for download from the Lowrance web site, www.lowrance.com.  
You can save several different sonar log files, erase 'em and record new  
ones, over and over again. The size of your sonar recordings is only  
limited by the free space available on your MMC.  
How LMS-480 GPS Works  
You'll navigate faster and easier if you understand how the LMS-480  
scans the sky to tell you where you are on the earth — and, where  
you're going. (But if you already have a working understanding of GPS  
receivers and the GPS navigation system, skip on ahead to Section 2,  
Installation & Accessories on page 13. If you're new to GPS, read on, and  
you can later impress your friends with your new-found knowledge.)  
First, think of your LMS-480 as a small but powerful computer. (But  
don't worry — we made the LMS-480 series easy to use, so you don't  
need to be a computer expert to find your way!) The unit includes a  
keypad and a screen with menus so you can tell LMS-480 what to do.  
The screen also lets LMS-480 show your location on a moving map, as  
well as point the way to your destination.  
This gimbal-mounted unit uses an external antenna/receiver module,  
which makes the whole system work something like your car radio. But  
instead of your favorite dance tunes, this receiver tunes in to a couple of  
dozen GPS satellites circling the earth. (It will also listen in to the  
WAAS satellites in orbit, but more about that in the upcoming segment  
introducing you to GPS and WAAS.)  
Your LMS-480 listens to signals from as many satellites as it can "see"  
above the horizon, eliminates the weakest signals, then computes its  
6
Download from Www.Somanuals.com. All Manuals Search And Download.  
location in relation to those satellites. Once LMS-480 figures its lati-  
tude and longitude, it plots that position on the moving map shown on  
the screen. The whole process takes place several times a second!  
The performance doesn't stop there. Stored in the permanent memory  
of each LMS-480 is a basic background map of the entire world. We lock  
it in here at the factory — you can't change or erase this map.  
The background map is suitable for many navigation chores, but for  
maximum accuracy and much more detail, you need our optional map-  
making software, MapCreate6. Some unit features — such as  
searching for businesses and addresses — won't work without a custom  
MapCreate map. There is so much detail in our background map (and  
even more in MapCreate) that we'll describe their contents and differ-  
ences in Section 6, Basic GPS Operations, on page 108.  
Another portion of LMS-480's onboard memory is devoted to recording  
GPS navigation information, which includes waypoints, event marker  
icons, trails and routes. This lets you look back the way you came.  
Think of this data storage like the hard drive memory in a computer or  
a tape in a cassette tape recorder. You can save several different GPS  
data files, erase 'em and record new ones, over and over again. Like any  
computer file, these GPS Data Files (file format *.usr) can be shared  
between LMS-480s, other Lowrance GPS or sonar/GPS units, even per-  
sonal computers.  
LMS-480 has one more thing in common with a personal computer.  
Just as computers have a floppy disk drive for storing and exchanging  
files, the LMS-480 has a slot for an MMC (MultiMedia Card) or SDC  
(Secure Digital card) flash memory card. These solid-state memory de-  
vices are about the size of a postage stamp, but can hold data ranging  
from 8 MB to more than 256 MB in size. (Compare that to a floppy  
disk's 1.44 MB capacity!) LMS-480 uses all that MMC space for two key  
GPS purposes. (The MMC is also used to record sonar logs.)  
First, you can backup your onboard GPS Data Files by copying them to  
the MMC. Since the MMC is removable (like a floppy disk or a cassette  
tape), you can store these GPS Data Files on a personal computer  
equipped with an MMC card reader. (Or store them on a pocketful of  
MMCs, if you don't have a computer.) Our MapCreate mapping software  
can save, edit or create its own GPS Data Files, which can be copied to  
the MMC and then loaded from the MMC into LMS-480's memory.  
(NOTE: No matter where they come from, GPS Data Files must be  
loaded from the MMC into memory before LMS-480 can use them.)

The other key GPS use for MMCs is storage of special high-detail, cus-  
tom maps, which you can produce on your computer with our MapCre-  
ate software. These MapCreate custom maps contain much greater de-  
tail than the basic background map. These Custom Map Files (file  
format *.lcm) can also be shared between LMS-480s, other Lowrance  
GPS or sonar/GPS units and personal computers. (For example, the  
exact same MMC, custom map files and GPS data files can be used in-  
terchangeably between your gimbal-mounted LMS-480 and the hand-  
held iFINDERGPS receiver.)  
LMS-480 automatically reads Custom Map Files directly from the  
MMC or SDC. To use a custom map, all you need to do is slide an MMC  
containing a map into the unit.  
Introduction to GPS and WAAS  
Well, now you know the basics of how LMS-480 does its work. You  
might be ready to jump ahead to Section 2, Installation & Accessories,  
on page 13, so you can mount your unit and plug in the power. Or you  
might want to see how our text formatting makes the manual tutorials  
easy to skim. If that's the case, move on to "How to Use This Manual"  
on page 10. But, if you want to understand the current state of satellite  
navigation, look over this segment describing how GPS and its new  
companion WAAS work together to get you where you're going.  
The Global Positioning System (GPS) was launched July 17, 1995 by  
the United States Department of Defense. It was designed as a 24-  
hour-a-day, 365-days-a-year, all weather global navigation system for  
the armed forces of the U.S. and its allies. Civilian use was also avail-  
able at first, but it was less accurate because the military scrambled  
the signal somewhat, using a process called Selective Availability (SA.)  
GPS proved so useful for civilian navigation that the federal govern-  
ment discontinued SA on May 2, 2000, after the military developed  
other methods to deny GPS service to enemy forces. Reliable accuracy  
for civilian users jumped from 100 meters (330 feet) under SA to the  
present level of 10 to 20 meters (about 30 to 60 feet.)  
Twenty-four satellites orbit 10,900 nautical miles above the Earth,  
passing overhead twice daily. A series of ground stations (with precisely  
surveyed locations) controls the satellites and monitors their exact loca-  
tions in the sky. Each satellite broadcasts a low-power signal that identi-  
fies the satellite and its position above the earth. Three of these satellites  
are spares, unused until needed. The rest virtually guarantee that at  
least four satellites are in view nearly anywhere on Earth at all times.

A minimum of three satellites are required to determine a 2D fix.  
The system requires signal reception from three satellites in order to  
determine a position. This is called a 2D fix. It takes four satellites to  
determine both position and elevation (your height above sea level —  
also called altitude.) This is called a 3D fix.  
Remember, the unit must have a clear view of the satellites in order to  
receive their signals. Unlike radio or television signals, GPS works at  
very high frequencies. These signals can be easily blocked by trees,  
buildings, an automobile roof, even your body.  
Like most GPS receivers, LMS-480 doesn’t have a compass or any other  
navigation aid built inside. It relies solely on the signals from the sat-  
ellites to calculate a position. Speed, direction of travel, and distance  
are all calculated from position information. Therefore, in order for  
LMS-480 to determine direction of travel, you must be moving and the  
faster, the better. This is not to say that it won’t work at walking or  
trolling speeds — it will. There will simply be more "wandering" of the  
data shown on the display.  
GPS alone is plenty accurate for route navigation, but the U.S. Federal  
Aviation Administration has special aircraft navigation needs that go  
beyond basic GPS. So, the FAA has developed a program to boost GPS  
performance with its Wide Area Augmentation System, or WAAS. The  
FAA commissioned the system on July 11, 2003.  
WAAS is designed to increase GPS accuracy to within 7.6 meters vertically  
and horizontally, but it consistently delivers accuracies within 1-2 meters  
horizontal and 2-3 meters vertical, according to the FAA. It does this by

broadcasting correction signals on GPS frequencies. Your unit automati-  
cally receives both GPS and WAAS signals.  
However, there are some fringe areas of the U.S., including parts of  
Alaska, that do not yet receive robust WAAS coverage. Continued WAAS  
development is planned to extend WAAS coverage in the years to come.  
WAAS boosts the accuracy of land GPS navigation, but the system is  
designed for aircraft. The satellites are in a fixed orbit around the  
Equator, so they appear very low in the sky to someone on the ground  
in North America. Aircraft and vessels on open water can get consis-  
tently good WAAS reception, but terrain, foliage or even large man-made  
structures can sometimes block the WAAS signal from ground receivers.  
You'll find that using your GPS receiver is both easy and amazingly  
accurate. It’s easily the most accurate method of electronic navigation  
available to the general public today. Remember, however, that this  
receiver is only a tool. Always have another method of navigation avail-  
able, such as a map or chart and a compass.  
Also remember that this unit will always show navigation information  
in the shortest line from your present position to a waypoint, regardless  
of terrain! It only calculates position, it can’t know what’s between you  
and your destination, for example. It’s up to you to safely navigate  
around obstacles, no matter how you’re using this product.  
How to use this manual: typographical conventions  
Many instructions are listed as numbered steps. The keypad and arrow  
"keystrokes" appear as boldface type. So, if you're in a real hurry (or  
just need a reminder), you can skim the instructions and pick out what  
menu command to use by finding the boldface command text. The fol-  
lowing paragraphs explain how to interpret the text formatting for  
those commands and other instructions:  
Arrow Keys  
The arrow keys control the movement of dotted cross-hair lines on your  
mapping screen called the cursor. The arrow keys also control a hori-  
zontal line depth cursor on the sonar screen. The arrow keys help you  
move around the menus so you can execute different commands. They  
are represented by symbols like these, which denote the down arrow  
key, the up arrow, the left arrow and the right arrow: ↓ ↑ ← .

Keyboard  
The other keys perform a variety of functions. When the text refers to a  
key to press, the key is shown in bold, sans serif type. For example, the  
"Enter/Icons" key is shown as ENT and the "Menu" key is shown as MENU.  
Menu Commands  
A menu command or a menu option will appear in small capital letters, in  
a bold sans serif type like this: ROUTE PLANNING. These indicate that you are  
to select this command or option from a menu or take an action of some  
kind with the menu item. Text that you may need to enter or file names  
you need to select are show in italic type, such as trail name.  
Instructions = Menu Sequences  
Most functions you perform with LMS-480 are described as a sequence  
of key strokes and selecting menu commands. We've written them in a  
condensed manner for quick and easy reading.  
For example, instructions for navigating a trail would look like this:  
1. From the Map Page, press MENU|MENU|to MY TRAILS|ENT.  
2. Press to Trail 1|ENT||to NAVIGATE|ENT.  
3. You are asked to wait while it converts the trail into a route.  
4. The wait message disappears and the unit begins showing  
navigation information along the trail. Now, begin moving and  
follow your LMS-480.  
Translated into complete English, step 1 above would mean: "Start on  
the Map Page. Press the Menu key twice. Next, repeatedly press (or  
press and hold) the down arrow key to scroll down the menu and select  
(highlight) the My Trails menu command. Finally, press the Enter key."  
Step 2 would mean: "Press the down arrow key repeatedly to scroll to  
the trail named Trail 1, and press Enter. Next, press the right arrow  
key and then the down arrow key to highlight the Navigate command,  
then press Enter."

Section 2:  
Installation & Accessories  
Preparations  
You can install the sonar and GPS systems in some other order if you  
prefer, but we recommend this installation sequence:  
Caution:  
You should read over this entire installation section before drill-  
ing any holes in your vehicle or vessel!  
1. Determine the approximate location for the sonar/GPS unit, so you  
can plan how and where to route the cables for the antenna, transducer  
and power. This will help you make sure you have enough cable length  
for the desired configuration.  
2. Determine the approximate location for the transducer and its cable  
route.  
3. Determine the approximate location for the GPS antenna module  
and its cable route.  
4. Determine the location of your battery or other power connection,  
along with the power cable route.  
5. Install the transducer and route the transducer cable to the so-  
nar/GPS unit.  
6. Install the GPS antenna and route the antenna cable to the so-  
nar/GPS unit.  
7. Install the power cable and route it to the sonar/GPS unit.  
8. Mount the sonar/GPS unit to the bracket.  
Transducer Installation  
These instructions will help you install your Skimmertransducer on a  
transom, on a trolling motor or inside a hull. These instructions cover  
both single- and dual-frequency Skimmer transducers. Please read all  
instructions before proceeding with any installation.  
The smaller single-frequency Skimmers typically use a one-piece,  
stainless steel mounting bracket. The larger dual-frequency Skimmers  
typically use a two-piece, plastic mounting bracket. The trolling motor  
mount uses a one-piece plastic bracket with an adjustable strap.  
These are all "kick-up" mounting brackets. They help prevent damage if  
the transducer strikes an object while the boat is moving. If the trans-  
ducer does "kick-up," the bracket can easily be pushed back into place  
without tools.  
13

Read these instructions carefully before attempting the installation.  
Determine which of the mounting positions is right for your boat. Re-  
member, the transducer installation is the most critical part of a  
sonar installation.  
NOTE:  
The following installation types also call for these recommended  
tools and required supplies that you must provide (supplies listed  
here are not included):  
Single-frequency transom installations  
Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flat-  
head screwdriver. Supplies: high quality, marine grade above- or below-  
waterline sealant/adhesive compound.  
Dual-frequency transom installations  
Tools: two adjustable wrenches, drill, #20 (0.161") drill bit, flat-head  
screwdriver. Supplies: four, 1" long, #12 stainless steel slotted wood screws,  
high quality, marine grade above- or below-waterline sealant/adhesive  
compound.  
Single-frequency trolling motor installations  
Tools: two adjustable wrenches, flat-head screwdriver. Supplies: plastic  
cable ties.  
Shoot-through hull installations  
Tools: these will vary depending on your hull's composition. Consult your  
boat dealer or manufacturer. Other tools are a wooden craft stick or  
similar tool for stirring and applying epoxy, and a paper plate or piece  
of cardboard to mix the epoxy on. Supplies: rubbing alcohol, 100 grit  
sandpaper, specially formulated epoxy adhesive available from LEI (see  
ordering information on the inside back cover). A sandwich hull also  
requires polyester resin.  
Selecting a Transducer Location  
1. The location must be in the water at all times, at all operating speeds.  
2. The transducer must be placed in a location that has a smooth flow of  
water at all times. If the transducer is not placed in a smooth flow of  
water, interference caused by bubbles and turbulence will show on  
the sonar's display in the form of random lines or dots whenever the  
boat is moving.  
NOTE:  
Some aluminum boats with strakes or ribs on the outside of the  
hull create large amounts of turbulence at high speed. These boats  
typically have large outboard motors capable of propelling the boat  
14  
Download from Www.Somanuals.com. All Manuals Search And Download.  
at speeds faster than 35 mph. Typically, a good transom location on  
aluminum boats is between the ribs closest to the engine.  
3. The transducer should be installed with its face pointing straight  
down, if possible. For shoot-thru applications: Many popular fishing  
boat hulls have a flat keel pad that offers a good mounting surface. On  
vee hulls, try to place the transducer where the deadrise is 10° or less.  
Deadrise less than 10°  
Strakes  
Pad  
Left, vee pad hull; right, vee hull. A pod style transducer is shown  
here, but the principle is the same for Skimmers inside a hull.  
4. If the transducer is mounted on the transom, make sure it doesn't  
interfere with the trailer or hauling of the boat. Also, don't mount it  
closer than approximately one foot from the engine's lower unit. This  
will prevent cavitation (bubble) interference with propeller operation.  
5. If possible, route the transducer cable away from other wiring on the  
boat. Electrical noise from engine wiring, bilge pumps and aerators  
can be displayed on the sonar's screen. Use caution when routing the  
transducer cable around these wires.  
CAUTION: Clamp the trans-  
ducer cable to transom near  
the transducer. This will help  
prevent the transducer from  
entering the boat if it is  
knocked off at high speed.

How low should you go?  
For most situations, you should install your Skimmer transducer so  
that its centerline is level with the bottom of the boat hull. This will

usually give you the best combination of smooth water flow and protec-  
tion from bangs and bumps.  
Transom  
Transducer  
centerline  
Hull bottom  
Align transducer centerline with hull bottom.  
However, there are times when you may need to adjust the transducer  
slightly higher or lower. (The slots in the mounting brackets allow you  
to loosen the screws and slide the transducer up or down.) If you fre-  
quently lose bottom signal lock while running at high speed, the trans-  
ducer may be coming out of the water as you cross waves or wakes.  
Move the transducer a little lower to help prevent this.  
If you cruise or fish around lots of structure and cover, your transducer  
may be frequently kicking up from object strikes. If you wish, you may  
move the transducer a little higher for more protection.  
There are two extremes you should avoid. Never let the edge of the  
mounting bracket extend below the bottom of the hull. Never let the  
bottom – the face – of the transducer rise above the bottom of the hull.  
Shoot-thru-hull vs. Transom Mounting  
In a shoot-thru-hull installation, the transducer is bonded to the inside  
of the hull with epoxy. The sonar "ping" signal actually passes through  
the hull and into the water. This differs from a bolt-thru-hull installa-  
tion (often called simply "thru-hull"). In that case, a hole is cut in the  
hull and a specially designed transducer is mounted through the hull  
with a threaded shaft and nut. This puts the transducer in direct contact  
with the water.  
Typically, shoot-thru-hull installations give excellent high speed opera-  
tion and good to excellent depth capability. There is no possibility of  
transducer damage from floating objects, as there is with a transom-  
mounted transducer. A transducer mounted inside the hull can't be  
knocked off when docking or loading on a trailer.  
However, the shoot-thru-hull installation does have its drawbacks.  
First, some loss of sensitivity does occur, even on the best hulls. This  
varies from hull to hull, even from different installations on the same  
hull. This is caused by differences in hull lay-up and construction.  
16  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Second, the transducer angle cannot be adjusted for the best fish arches  
on your sonar display. (This is not an issue for flasher-style sonars.)  
Lack of angle adjustment can be particularly troublesome on hulls that  
sit with the bow high when at rest or at slow trolling speeds.  
Third, a transducer CAN NOT shoot through wood and metal hulls.  
Those hulls require either a transom mount or a thru-hull installation.  
Fourth, if your Skimmer transducer has a built in temp sensor, it will  
only show the temperature of the bilge, not the water surface temp.  
Follow the testing procedures listed in the shoot-thru-hull installation  
section at the end of this lesson to determine if you can satisfactorily  
shoot through the hull.  
TRANSOM TRANSDUCER ASSEMBLY AND MOUNTING  
The best way to install these transducers is to loosely assemble all of the  
parts first, place the transducer's bracket against the transom and see if  
you can move the transducer so that it's parallel with the ground.  
The following instructions sometimes vary depending on the mounting  
bracket that came with your transducer. Single-frequency Skimmers  
come with a one-piece stainless steel bracket, while dual-frequency  
Skimmers come with a two-piece plastic mounting bracket. Use the set of  
instructions that fits your model.  
1. Assembling the bracket.  
A. One-piece bracket: Press the two small plastic ratchets into the  
sides of the metal bracket as shown in the following illustration. Notice  
there are letters molded into each ratchet. Place each ratchet into the  
bracket with the letter "A" aligned with the dot stamped into the metal  
bracket. This position sets the transducer's coarse angle adjustment for a  
14° transom. Most outboard and stern-drive transoms have a 14° angle.  
Dot  
Align plastic ratchets in bracket.  
B. Two-piece bracket: Locate the four plastic ratchets in the trans-  
ducer's hardware package. Press two ratchets into the sides of the plas-  
tic bracket and two on either side of the transducer as shown in the fol-  
lowing illustrations. Notice there are letters molded into each ratchet.  
17

Place the ratchets into the bracket with the letter "A" aligned with the  
alignment mark molded into the bracket. Place the ratchets onto the  
transducer with the letter "A" aligned with the 12 o'clock position on  
the transducer stem. These positions set the transducer's coarse angle  
adjustment for a 14° transom. Most outboard and stern-drive tran-  
soms have a 14° angle.

2. Aligning the transducer on the transom.  
A. One-piece bracket: Slide the transducer between the two ratch-  
ets. Temporarily slide the bolt though the transducer assembly and  
hold it against the transom. Looking at the transducer from the side,  
check to see if it will adjust so that its face is parallel to the ground.  
If it does, then the "A" position is correct for your hull.  
18  
Download from Www.Somanuals.com. All Manuals Search And Download.  
If the transducer's face isn't parallel with the ground, remove the  
transducer and ratchets from the bracket. Place the ratchets into the  
holes in the bracket with the letter "B" aligned with the dot stamped  
in the bracket.  
Reassemble the transducer and bracket and place them against the  
transom. Again, check to see if you can move the transducer so it's  
parallel with the ground. If you can, then go to step 3A. If it doesn't,  
repeat step 2A, but use a different alignment letter until you can  
place the transducer on the transom correctly.  
Ratchets  
Insert bolt and check transducer position on transom.  
B. Two-piece bracket: Assemble the transducer and bracket as shown  
in the following figure. Temporarily slide the bolt though the transducer  
assembly but don't tighten the nut at this time. Hold the assembled  
transducer and bracket against the transom. Looking at the transducer  
from the side, check to see if it will adjust so that its face is parallel to  
the ground. If it does, then the "A" positions are correct for your hull.  
If the transducer's face isn't parallel with the ground, remove and  
disassemble the transducer and ratchets. Place the ratchets into the  
bracket holes with the letter "B" aligned with the bracket alignment  
mark. Place them on the transducer aligned with the 12 o'clock posi-  
tion on the transducer stem.  
Reassemble the transducer and bracket and place them against the  
transom. Again, check to see if you can move the transducer so it's  
parallel with the ground. If you can, then go to step 3B. If it doesn't,  
repeat step 2B, but use a different alignment letter until you can  
place the transducer on the transom correctly.

4. Drilling mounting holes.  
Hold the transducer and bracket assembly against the transom. The  
transducer should be roughly parallel to the ground. The trans-  
ducer's centerline should be in line with the bottom of the hull. Don't  
let the bracket extend below the hull!  
Mark the center of each slot for the mounting screw pilot holes. You  
will drill one hole in the center of each slot.  
Drill the holes. For the one-piece bracket, use the #29 bit (for the #10  
screws). For the two-piece bracket, use the #20 bit (for the #12 screws).

bolt as shown in the following figures.  
For single-frequency Skimmer, route cable over bolt and through  
bracket. Side view shown at left and seen from above at right.  
Both bracket types: Attach the transducer to the transom. Slide the  
transducer up or down until it's aligned properly with the bottom of  
the hull as shown in the preceding and following figures. Tighten the  
bracket's mounting screws, sealing them with the sealant.  
Adjust the transducer so that it's parallel to the ground and tighten  
the nut until it touches the outer washer, then add 1/4 turn. Don't  
over tighten the lock nut! If you do, the transducer won't "kick-up" if  
it strikes an object in the water.

6. Route the transducer cable through or over the transom to the sonar  
unit. Make sure to leave some slack in the cable at the transducer. If  
possible, route the transducer cable away from other wiring on the  
boat. Electrical noise from the engine's wiring, bilge pumps, VHF radio  
wires and cables, and aerators can be picked up by the sonar. Use cau-  
tion when routing the transducer cable around these wires.  
WARNING:  
Clamp the transducer cable to the transom close to the  
transducer. This can prevent the transducer from enter-  
ing the boat if it is knocked off at high speed.  
If you need to drill a hole in the transom to pass the connector through,  
the required hole size be 1".  
Caution:  
If you drill a hole in the transom for the cable, make sure it is lo-  
cated above the waterline. After installation, be sure to seal the  
hole with the same marine grade above- or below-waterline seal-  
ant used for the mounting screws.  
7. Make a test run to determine the results. If the bottom is lost at  
high speed, or if noise appears on the display, try sliding the trans-  
ducer bracket down. This puts the transducer deeper into the water,  
hopefully below the turbulence causing the noise. Don't allow the  
transducer bracket to go below the bottom of the hull!

TROLLING MOTOR BRACKET INSTALLATION  
(single-frequency only)  
1. Attach the optional TMB-S bracket to the transducer as shown in the  
following figure, using the hardware supplied with the transducer.  
(Note: The internal tooth washer is supplied with the TMB-S.)

2. Slide the adjustable strap supplied with the TMB-S through the slot  
in the transducer bracket and wrap it around the trolling motor. Po-  
sition the transducer to aim straight down when the motor is in the  
water. Tighten the strap securely.  
3. Route the transducer cable alongside the trolling motor shaft. Use  
plastic ties (not included) to attach the transducer cable to the troll-  
ing motor shaft. Make sure there is enough slack in the cable for the  
motor to turn freely. Route the cable to the sonar unit and the trans-  
ducer is ready for use.

TRANSDUCER ORIENTATION AND FISH ARCHES  
If you do not get good fish arches on your display, it could be because  
the transducer is not parallel with the ground when the boat is at rest  
in the water or at slow trolling speeds.

If the arch slopes up – but not back down – then the front of the trans-

arch is printed, then the nose of the transducer is angled too far down  
and needs to be raised.  
NOTE:  
Periodically wash the transducer's face with soap and water to re-  
move any oil film. Oil and dirt on the face will reduce the sensitivity  
or may even prevent operation.  
SHOOT-THRU-HULL PREPARATION  
Hulls With Floatation Materials  
The transducer installation inside a fiberglass hull must be in an area  
that does not have air bubbles in the resin or separated fiberglass lay-  
ers. The sonar signal must pass through solid fiberglass. A successful  
transducer installation can be made on hulls with flotation materials  
(such as plywood, balsa wood or foam) between layers of fiberglass if  
the material is removed from the chosen area. See the following figure.  
24  
Download from Www.Somanuals.com. All Manuals Search And Download.  
WARNING:  
Do not remove any material from your inner hull unless  
you know the hull's composition. Careless grinding or  
cutting on your hull can result in damage that could sink  
your boat. Contact your boat dealer or manufacturer to  
confirm your hull specifications.  
Fill with polyester resin  
Inner hull  
Flotation material  
Epoxy to hull first  
Outer hull  
Epoxy the transducer to a solid portion of the hull.  
For example, some (but not all) manufacturers use a layer of fiberglass,  
then a core of balsa wood, finishing with an outer layer of fiberglass.  
Removing the inner layer of fiberglass and the balsa wood core exposes  
the outer layer of fiberglass. The transducer can then be epoxied di-  
rectly to the outer layer of fiberglass. After the epoxy cures for 24  
hours, fill the remaining space with polyester resin. When the job is  
finished, the hull is watertight and structurally sound. Remember, the  
sonar signal must pass through solid fiberglass. Any air bubbles in the  
fiberglass or the epoxy will reduce or eliminate the sonar signals.  
Testing Determines Best Location  
Ideally, the shoot-thru transducer should be installed as close to the  
transom as possible, close to the centerline. This will give you the best  
performance during high speed maneuvers.

To choose the proper location for shoot-thru-hull mounting, follow these  
testing procedures: (You may need a helper to complete these steps.)  
1. Anchor the boat in about 30 feet of water. Add a little water to the  
sump of the boat. Plug the transducer into the sonar unit, turn it on,  
then hold the transducer over the side of the boat in the water. Adjust  
the sensitivity and range controls until a second bottom echo is seen on  
the display. (You'll need to turn off Auto Sensitivity, Auto Depth Range  
and ASP. Try a range setting that is two to three times the water  
depth. The harder (more rocky) the bottom, the easier it will be to get a  
second bottom signal.) Don't touch the controls once they've been set.  
True bottom  
Second bottom  
Manual range setting  
Example of a second bottom signal. Unit is in 30 feet of water, with  
range set at 80 feet and sensitivity set at 87 percent.  
2. Next, take the transducer out of the water and place it in the water in  
the sump of the boat, face down. (The transducer face is shown in the  
figure on the following page.) Notice how the signal strength de-  
creases. The second bottom signal will probably disappear and the bot-  
tom signal intensity will likely decrease.  
3. Now move the transducer around to find the best location with the  
strongest possible bottom signal. If you find a spot with an acceptable  
bottom signal, mark the location and move on to step 4.  
If you can't get an acceptable bottom signal, try turning up the sensi-  
tivity by three or five keystrokes and then move the transducer around  
once more. If you find a spot that works, mark it and move on to step 4.  
If you have to turn up sensitivity by more than five keystrokes to get a  
good signal, the transducer should be mounted on the outside of the  
hull. This is especially true if you have to turn sensitivity all the way  
up to get a decent bottom signal.

4. Most people can get good results by following steps 1 through 3, so this  
step is optional. If you want to make an extra effort to be absolutely sure  
that your selected location will work under all conditions, make a test  
run with the boat on plane and observe the bottom signal. You'll need to  
figure some way to prop the transducer into position while you make  
your test run. (A brick or two might be sufficient to hold it in place.)  
5. When you're satisfied with a location, mark it and proceed with  
the installation.  
Shoot-thru-hull Installation  
If you are installing the transducer on a hull with floatation material  
sandwiched within the hull, refer to the text "Hulls With Flotation Ma-  
terials" beginning on page 24.  
1. Make sure the area is clean, dry and free of oil or grease, then sand  
both the inside surface of the hull and the face of the transducer with  
100 grit sandpaper. The sanded hull area should be about 1-1/2 times  
the diameter of the transducer. The surface of the hull must be flat  
so the entire transducer face is in contact with the hull prior to  
bonding. After sanding, clean the hull and transducer with rubbing  
alcohol to remove any sanding debris.  
Spread epoxy here  
Sand this surface  
Epoxy transducer to hull.  
WARNING:  
Use only the epoxy available from LEI. It has been for-  
mulated to work with these installation procedures.  
Other epoxy types may be too thin or may not cure to the  
right consistency for optimum transducer performance.  
27  
Download from Www.Somanuals.com. All Manuals Search And Download.  
2. The epoxy consists of the epoxy itself and a hardener. Remove the  
two compounds from the package and place them on the paper plate.  
Thoroughly stir the two compounds together until the mixture has a  
uniform color and consistency. Do not mix too fast or bubbles will  
form in the epoxy. After mixing, you have 20 minutes to complete the  
installation before the epoxy becomes unworkable.  
Spread a thin layer of epoxy (about 1/16" or 1.5 mm thick) on the face  
of the transducer as shown in the previous figure. Make sure there  
are no air pockets in the epoxy layer! Then, apply the remaining ep-  
oxy to the sanded area on the hull.  
3. Press the transducer into the epoxy, twisting and turning it to force  
any air bubbles out from under the transducer face. Stop pressing  
when you bottom out on the hull. When you're finished, the face of  
the transducer should be parallel with the hull, with a minimum  
amount of epoxy between the hull and transducer.  
4. Apply a weight, such as a brick, to hold the transducer in place while  
the epoxy cures. Be careful not to bump the transducer while the ep-  
oxy is wet. Leave the weight in place for a minimum of three hours.  
Allow the epoxy to cure for 24 hours before moving the boat.  
5. After the epoxy has cured, route the cable to the sonar unit and it's  
ready to use.  
Speed/Temperature Sensors  
Optional Speed Sensor Installation  
All the units in this series can display speed and distance traveled, but  
only the LMS-480DF comes packed with a speed sensor. If you wish to  
purchase an optional additional sensor for your unit, refer to the acces-  
sory ordering information inside the back cover of this manual. The  
following instructions describe how to install the speed sensor.  
Recommended tools for this job include: drill, 7/8" drill bit, 1/8" drill bit  
for pilot holes, screwdriver. Required supplies for this job include: four  
#8 stainless steel wood screws (3/4" long), high quality, marine grade  
above- or below-waterline sealant.  
First find a location on the boat's transom where the water flow is  
smoothest. Don't mount the sensor behind strakes or ribs. These will  
disturb the water flow to the speed sensor. Make sure the sensor will  
remain in the water when the boat is on plane. Also make sure the lo-  
cation doesn't interfere with the boat's trailer. Typically, the sensor is  
mounted about one foot to the side of the transom's centerline.  
28  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Once you've determined the proper location for the unit, place the sen-  
sor on the transom. The bottom of the bracket should be flush with the  
hull's bottom. Using the sensor as a template, mark the hull for the  
screws' pilot holes. Drill four 1/8" holes, one in each end of the slots.  
Mount the sensor to the hull using #8 stainless steel wood screws (not  
included). Use a high quality, marine grade above- or below-waterline  
sealant to seal the screws. Make sure the sensor is flush with the bot-  
tom of the hull and tighten the screws.

If the base of the transom has a radius, fill the gap between the tran-  
som and the sensor with the sealant. This will help ensure a smooth  
water flow.  
Route the sensor's cable through or over the transom to the sonar unit.  
If you need to drill a hole in the transom to pass the connector through,  
the required hole size is 7/8".  
CAUTION:  
If you drill a hole in the transom for the cable, make sure it is lo-  
cated above the waterline. After installation, be sure to seal the  
hole with the same marine grade above- or below-waterline seal-  
ant used for the screws.  
The sensor is now ready for use. Connect the sensor to the sonar socket  
on the back of your unit and connect the transducer to the speed sen-

sor's socket. If you have any questions concerning the installation of the  
sensor, please contact your local boat dealer.  
GPS Antenna/Receiver Module  
The LMS-480 series package includes the LGC-2000 GPS module. This  
device contains the unit's external antenna and receiver for GPS and  
WAAS signals. The antenna/receiver module comes with a 25-foot Y-  
adapter extension cable. This module can be mounted on a flat surface  
or pole, or an optional magnet is available for temporary mounting on  
any ferrous surface.  
LGC-2000 Module, bottom view (left) and top view (right).  
You need to select an antenna installation location that has a clear, un-  
obstructed view of the sky. After the module is installed, connect it to  
the end of the Y-adapter extension cable as shown in the following dia-  
gram. To connect it to the LMS-480, insert the cable's splitter plug into  
the Network socket on the back of the unit and your system is ready to  
use. See the module's instruction sheet, publication part number 988-  
0147-791, for complete installation directions.

In an automobile, you may achieve good results by simply placing the  
external antenna on the top of the dash, at the base of the windshield. A  
piece of the rubber non-skid shelf liner material available in recreational  
vehicle supply stores will help hold the antenna in place. This may not  
work well if you have a cab-over design pickup truck camper or motor  
home. If dashboard reception is poor, simply relocate the antenna mod-  
ule elsewhere on the vehicle for a clearer view of the sky.  
Power Connections  
Your unit comes with a power/data cable that splits into three ends,  
each with several exposed wires (shown in the following figure). The  
end with 4 wires (blue, yellow, orange and shield) is a Data cable that  
connects to a NMEA 0183 interface. The end with three wires (red,  
black and shield) is a power cable that connects to a NMEA-2000 buss.  
The thicker three-wire cable (red, black and white) is the Power Supply  
for your unit (and optional external speaker connection for some units).

Depending on your configuration, you may not use all of these wires.  
(For example, many units cannot operate an optional external speaker,  
so the white wire on the Power Supply cable isn't functional.) The fol-  
lowing segments include instructions for installing all the wires that  
you will use with this unit.  
Powering a NMEA-2000 Buss  
(NMEA-2000 Power cable)  
A NMEA-2000 buss must be connected to a power source to operate. If  
you have a pre-existing NMEA-2000 installation, it may already be  
connected to another power source. If your NMEA-2000 buss is already  
powered, you can ignore the NMEA-2000 Power cable. Never attach  
two power sources to a single NMEA-2000 buss.  
If you do need to power your NMEA-2000 buss, attach the NMEA-2000  
Power cable to your boat's battery just as indicated in the following  
segment for connecting your unit's Power Supply cable. The NMEA-  
31  
Download from Www.Somanuals.com. All Manuals Search And Download.  
2000 Power cable's red wire should be attached (with provided 3-amp  
fuse) to the boat battery's positive terminal, and the NMEA-2000 Power  
cable's black and shield wires should both be attached to the battery's  
negative terminal.  
NOTE:  
If the NMEA-2000 buss draws power directly from the boat's battery,  
the LGC-2000 will remain on (drawing power) all the time. The LGC-  
2000's current draw is very small and shouldn't decrease the boat's  
storage battery life, but if this small draw is a concern, you can in-  
stall a switch between the NMEA-2000 buss and the battery.  
Powering Your Unit  
(Power Supply cable – red and black wires)  
The unit works from a 12-volt battery system. For the best results, at-  
tach the power cable directly to the battery. You can attach the power  
cable to an accessory or power buss, however you may have problems  
with electrical interference. Therefore, it's safer to go ahead and attach  
the power cable directly to the battery.  
CAUTION:  
When using the unit in a saltwater environment, we strongly rec-  
ommend that you shut off the power supply to the power cable when  
the unit is not in use. When the unit is turned off but still connected  
to a power supply, electrolysis can occur in the power cable plug.  
This may result in corrosion of the plug body along with the electri-  
cal contacts in the cable and the unit's power socket.  
In saltwater environments we recommend you connect the power  
cable to the auxiliary power switch included in most boat designs.  
If that results in electrical interference, or if such a switch is not  
available, we recommend connecting direct to the battery and in-  
stalling an inline switch. This will let you shut off power to the  
power cable when the unit is not in use. When you are not using  
the unit, you should always shut off power to the power cable, es-  
pecially when the power cable is disconnected from the unit.  
If possible, keep the power cable away from other boat wiring, especially  
the engine's wires. This will provide the best isolation from electrical  
noise. If the cable is not long enough, splice #18 gauge wire onto it. The  
power cable has two wires, red and black. Red is the positive lead, black  
is negative or ground. (There is also a white wire to power an optional  
external speaker for some units.) Make sure to attach the in-line fuse  
holder to the red lead as close to the power source as possible.  
32

For example, if you have to extend the power cable to the battery or  
power buss, attach one end of the fuse holder directly to the battery or  
power buss. This will protect both the unit and the power cable in the  
event of a short. It uses a 3-amp fuse.

If you're powering a NMEA-2000 buss, you will attach both the  
NMEA-2000 Power cable and the unit's Power Supply cable to the  
boat's battery. To attach the NMEA-2000 Power cable, connect the  
red wire to battery's + and black and shield wires to battery's –.  
WARNING:  
This product must be independently fused with the en-  
closed 3-amp fuse (or equivalent), even if you connect to  
a fused accessory or power buss.  
If a malfunction happens inside the unit, extensive dam-  
age can occur if the enclosed fuse is not used. As with all  
electrical devices, this unit could be damaged to a point  
that it is unrepairable and could even cause harm to the  
user when not properly fused.  
CAUTION:  
Do not use this product without a 3-amp fuse wired into the power  
cable! Failure to use a 3-amp fuse will void your warranty.  
This unit has reverse polarity protection. No damage will occur if the  
power wires are reversed. However, the unit will not work until the  
wires are attached correctly.

NMEA 0183/DGPS Cable Connections  
NMEA is a standard communications format for marine electronic  
equipment. For example, an autopilot can connect to the NMEA inter-  
face on the LMS-480 and receive positioning information. The LMS-480  
can exchange information with any device that transmits or receives  
NMEA 0183 data.  
DGPS is an acronym for the Differential Global Positioning System.  
DGPS supplements and boosts the accuracy of basic GPS. DGPS was  
developed by the U.S. Coast Guard, which is responsible for the sys-  
tem's operation in the United States. Since it's creation, DGPS has be-  
come the international maritime standard for marine navigation.  
The most popular DGPS system relies on a grid of ground-based trans-  
mitters that send correction signals to DGPS receivers. These in turn,  
connect to the GPS receiver (such as the LMS-480). Lowrance offers an  
optional DGPS receiver for your unit.  
See the following diagram for general wiring connections. Read your  
other product’s owner’s manual for more wiring information.  
NMEA/DGPS Wiring  
(Data cable)  
To exchange NMEA 0183 or DGPS data, the LMS-480 has one NMEA  
0183 version 2.0 communication port. Com port one (Com-1) can be  
used to receive NMEA format GPS data or DGPS data. The com port  
can also transmit NMEA format GPS data to another device.  
The four wires for the com port are combined with the Power Supply  
cable and NMEA-2000 Power cable to form the power/data cable  
(shown earlier). Com-1 uses the yellow wire to transmit, the orange  
wire to receive and the shield wire for signal ground. Your unit does not  
use the blue wire.

Mounting the Unit: Bracket, In-Dash or Portable  
You can install the LMS-480 on the top of a dash with the supplied  
gimbal bracket. It can also be installed in the dash or mounted on a  
portable power supply.  
If you use the supplied bracket, you may be interested in the optional  
R-A-Mbracket mounting system. This converts the unit's gimbal  
bracket to a swivel mount, which can be used on the dash or overhead  
mounting positions.  
Optional R-A-M mounting system.  
Bracket Installation  
Mount the unit in any convenient location, provided there is clearance  
behind the unit when it's tilted for the best viewing angle. You should also  
make sure there is enough room behind the unit to attach the power,  
transducer and GPS antenna/receiver module cables. (A drawing on the  
next page shows the dimensions of a gimbal-mounted unit.)  
Holes in the bracket's base allow wood screw or through-bolt mounting.  
You may need to place a piece of plywood on the back side of thin fiber-  
glass panels to reinforce the panel and secure the mounting hardware.

Front  
Install the gimbal bracket. Orient the bracket so the arms slope toward  
the front of your unit.  
Drill a 1-inch (25.4 mm) hole in the dash for the power, transducer and  
antenna cables. The best location for this hole is immediately under the  
gimbal bracket location. This way, the bracket can be installed so that  
it covers the hole, holds the cables in position and results in a neat in-  
stallation. Some customers, however, prefer to mount the bracket to the  
side of the cable hole — it's a matter of personal preference.

After drilling the hole, pass the transducer connector up through the  
hole from under the dash, followed by antenna connector. Pass the  
power cable's bare-wire end down though the hole from the top.  
If you wish, you can fill in the hole around the cables with a good ma-  
rine caulking compound. (Some marine dealers stock cable hole covers  
to conceal the opening.) No matter what type of installation you prefer,  
be sure to leave enough slack in the cables to allow tilting or swiveling  
the unit. If you choose to fill in the hole, be sure to position the cables  
against the rear edge of the hole as you apply the fill material.  
Before positioning the bracket, be sure to hold the cables against the  
rear edge of the hole. Then, slide the bracket over the hole and butt the  
rear of the bracket base firmly against the cables, thus pinning them in  
place against the side of the hole. Finally, fasten the bracket to the  
dash. Attach the unit to the gimbal bracket using the supplied gimbal  
knobs and washers.  
In-Dash Installation  
You can mount the unit in the dash with an optional FM-5 In-Dash  
Adapter Kit. The kit includes mounting hardware, a template for cut-  
ting the hole and an instruction sheet, part 988-0147-43.

Portable Installation  
Like many Lowrance products, the LMS-480 is capable of portable op-  
eration by using the optional PPP-11 portable power pack. The power  
pack, the magnet-equipped antenna module and an optional portable  
transducer expand the uses for your sonar/GPS unit. The PPP-11  
makes it easy to transfer your unit from a boat to a car, recreational  
vehicle, airplane or other vehicle without drilling and mounting a sec-  
ond bracket. You can use your unit in your own car or boat, then take it  
along when riding in a friend's vehicle that's not equipped with sonar or  
GPS. (Or use it as a second sonar, one for each fisherman!)  
The PPP-11 Portable Power Pack can be used with eight "D" cell alka-  
line batteries or an optional sealed, rechargeable battery. For set-up  
directions, refer to the pack's instruction sheet, part 988-0147-46.

MMC or SD Card Memory Card Installation  
Your LMS-480 uses a MultiMedia Card to store information, such as  
sonar logs, custom maps, waypoints, trails and other GPS data. The  
unit can also use Secure Digital Cards (SD card) to store data.  
NOTE:  
Throughout this manual, we will use the term MMC, but just re-  
member that your unit can use an MMC or SD card to store data.

NOTE:  
When you first turn the unit on, the Map Page appears. If you'd  
rather start learning about GPS operation first, turn over to Sec-  
tion 6, Basic GPS Operations. (Remember, you don't need to read  
this manual from cover-to-cover to get going. We designed it so you  
can skip around to the section you want to read.)  
Face Cover  
Your LMS-480 comes with a white protective cover that snaps on and  
off the front of the unit. This cover is intended for use when your unit  
and the vehicle it's mounted in are idle.  
WARNING:  
When the unit is mounted in an unprotected area, such  
as an open boat cockpit, the protective face cover must  
be removed when the vehicle is moving at high speed.  
This includes towing a boat on a trailer at highway  
speeds. Otherwise, wind blast can pop off the cover.

You can customize how the Sonar Page displays its pictures and other  
data in many ways. Your unit also includes several special sonar features  
and options that can help you better interpret the underwater scene.  
We'll discuss all of those features and options in Sec. 4, but to show you  
how easy this unit is to operate, the following page contains a simpli-  
fied, 10-step quick reference that will cover most fish finding situations.  
The quick reference describes how your unit will operate with all the  
sonar features in their automatic modes, which are set at the factory.

Basic Sonar Quick Reference  
1. Mount the transducer, antenna and unit. Connect the unit to electric  
power and the transducer. (If GPS operation is desired, connect GPS  
antenna, too.) Make sure the MMC is in. (See complete installation de-  
tails beginning on page 13.)  
2. Launch your boat.  
3. To turn on the unit, press and release PWR key.  
4. Opening screen displays Map Page. Rotate through the four main  
Page screens (Map Page, Satellite Status Page, Navigation Page, Sonar  
Page) by pressing PAGES|or to select Page Name|EXIT. Switch  
Pages to display Sonar Page.  
5. If GPS data is desired, wait while unit locates satellites and calculates  
current position. When the unit acquires position, a tone sounds and a posi-  
tion acquired message appears.  
6. With position acquired (if desired), head for your fishing grounds.  
Your unit will automatically display digital depth and surface water  
temperature in the top left corner of the screen.  
The auto settings will track the bottom, displaying it in the lower por-  
tion of the screen. The full sonar chart will scroll from right to left,  
showing you what's under the boat as you cruise across the water. You  
can change the display by:  
Zoom in to enlarge the chart for more detail: press ZIN.  
Zoom out to return to full chart mode: press ZOUT.  
7. Watch the display for the appearance of fish symbols (or arches, if  
Fish I.D.is turned off). When you see fish symbols or arches, you've  
found fish! Stop the boat and get your lure or bait into the water at the  
depth indicated on the sonar chart.  
8. Gauge the fish depth by visually comparing the fish symbols or  
arches with the depth scale on the right side of the screen, or get a  
more accurate measure with the Depth Cursor. Press MENU|to DEPTH  
CURSOR|ENT. Press or to align the cursor line with the fish arch. The  
exact depth appears in a box at the right end of the cursor line. To clear  
the cursor, press EXIT.  
9. If you are drifting at a very low speed or anchored, you are not mov-  
ing fast enough for a fish to return the tell-tale fish arch signal. As you  
drift over a fish, or as a fish swims through the transducer's signal  
cone, the fish echo will appear as a straight line suspended between the  
surface and the bottom when Fish I.D. is turned off.  
10. To turn off the unit, press and hold PWR key for three seconds.

Sonar Operations  
As you can see from the quick reference on the previous page, basic operation  
is pretty easy, right out of the box. If you are a sonar novice, try operating the  
unit with the factory defaults until you get a feel for how it's working.  
As you're learning the basics, there is one setting you might want to tinker  
with from time to time — Sensitivity.  
Sensitivity controls the unit's ability to pick up echoes. If you want to see  
more detail, try increasing the sensitivity, a little at a time. There are situa-  
tions when too much clutter appears on the screen. Decreasing the sensitivity  
can reduce the clutter and show the strongest fish echoes, if fish are present.  
As you change the sensitivity setting, you can see the difference on the chart  
as it scrolls.  
Fig. 1  
Fig. 2  
Fig. 3  
Fig. 4  
These figures show results of different sensitivity levels on the same lo-  
cation. Fig. 1: Sensitivity at 88 percent, determined by Auto Sensitivity.  
Typical of full auto mode. Fig. 2: Sensitivity set at 75 percent. Fig. 3: Sen-  
sitivity set at 50 percent. Fig. 4: Sensitivity set at 100 percent.  
52

You can change the sensitivity level whether you are in Auto Sensitivity  
mode or Manual Sensitivity mode. The adjustment method works the  
same in both modes, but it gives you slightly different results.  
Adjusting sensitivity in Auto Sensitivity Mode is similar to manually ad-  
justing a car's speed with the accelerator pedal while cruise control is on.  
You can tell the car to run faster, but when you let off the gas the cruise  
control automatically keeps you from running slower than the minimum  
speed setting. In the unit, auto mode will let you increase sensitivity to 100  
percent, but the unit will limit your minimum setting. This prevents you  
from turning sensitivity down too low to allow automatic bottom tracking.  
When you change the setting with auto turned on, the unit will continue to  
track the bottom and make minor adjustments to the sensitivity level, with  
a bias toward the setting you selected.  
Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a  
car without cruise control — you have complete manual control of the  
car's speed. In the unit, manual mode allows you to set sensitivity at  
100 percent (maximum) or zero percent (minimum.) Depending on wa-  
ter conditions, the bottom signal may completely disappear from the  
screen when you reduce sensitivity to about 50 percent or less!  
Try adjusting sensitivity in both auto and manual modes to see how  
they work.  
To adjust sensitivity:  
1. Press MENU|ENT.  
2. The Sensitivity Control Bar appears. Press to decrease sensitivity;  
press to increase sensitivity. When it's set at the desired level, press  
EXIT. (When you reach the maximum or minimum limit, a tone sounds.)  
At left, Sonar Menu with Sensitivity command selected. At right, the  
Sensitivity Control Bar.

NOTE:  
If you want to change the sensitivity in Manual Mode, first turn off  
Auto Sensitivity: from the Sonar Page, press MENU|to AUTO  
SENSITIVITY|ENT|to SENSITIVITY|ENT. Press or to pick a different  
sensitivity setting. When it's set at the desired level, press EXIT.  
Important Tip:  
While you are experimenting and learning, it's possible to scramble  
the settings so that the sonar picture disappears from your screen.  
If that happens, remember that it's easy to switch back to full  
automatic operation by simply restoring the factory auto settings.  
Here's how:  
To Restore Factory Settings  
1. Press MENU|MENU|to SYSTEM SETUP|ENT|to RESET OP-  
TIONS|ENT.  
2. The unit asks if you want to reset all the options. Press to  
YES|ENT. All options are reset, and the unit reverts back to the Map  
Page at the 4000 mile zoom range. (Any recorded sonar logs or GPS  
data will be unchanged.)  
Fish Symbols vs. Full Sonar Chart  
You may have noticed in the quick reference that we used fish arches in  
full sonar chart mode for our example, and not the popular Fish I.D.  
fish symbol feature. Here's why.  
Fish I.D. is an easier way for a sonar novice to recognize a fishy signal  
return when he sees it. However, locating fish by symbol only has some  
limitations.  
Your sonar unit's microprocessor is remarkably powerful, but it can be  
fooled. Some of the echoes calculated to be fish could be tree limbs or tur-  
tles! To see what's under your boat in maximum detail, we recommend  
you turn off Fish I.D. and begin learning to interpret fish arches.  
Fish I.D. is most handy when you're in another part of the boat or per-  
forming some task that prevents you from watching the sonar screen.  
Then, you can turn on Fish I.D. and the audible fish alarm. When that  
lunker swims under your boat, you'll hear it!  
Fish I.D. can also be useful when you want to screen out some of the  
sonar detail gathered by your unit. For example, in one case fisherman  
in San Francisco Bay saw clouds of clutter in the water but no fish  
arches. When a down rigger was pulled up, it brought up several small  
jellyfish. The fisherman switched their sonar to Fish I.D., which  
screened out the schools of jellyfish and clearly showed the game fish  
there as fish symbols.

Section 4: Sonar Options & Other Features  
Material in this section is arranged in alphabetical order.  
ASP(Advanced Signal Processing)  
The ASPfeature is a noise rejection system built into the sonar unit  
that constantly evaluates the effects of boat speed, water conditions  
and interference. This automatic feature gives you the best display pos-  
sible under most conditions.  
The ASP feature is an effective tool in combating noise. In sonar terms,  
noise is any undesired signal. It is caused by electrical and mechanical  
sources such as bilge pumps, engine ignition systems and wiring, air  
bubbles passing over the face of the transducer, even vibration from the  
engine. In all cases, noise can produce unwanted marks on the display.  
The ASP feature has four settings — Off, Low, Medium and High. If  
you have high noise levels, try using the "High" ASP setting. However,  
if you are having trouble with noise, we suggest that you take steps to  
find the interference source and fix it, rather than continually using the  
unit with the high ASP setting.  
There are times when you may want to turn the ASP feature off. This  
allows you to view all incoming echoes before they are processed by the  
ASP feature.  
At left, Sonar Menu with Sonar Features selected. In the Sonar  
Features menu, Noise Rejection is selected with ASP in the default low  
setting (center, dual-frequency menu; at right, single-frequency menu).

Alarms  
This unit has three different types of sonar alarms. The first is the Fish  
Alarm. It sounds when the Fish I.D.feature determines that an echo  
is a fish.  
Another alarm is the Zone Alarm, which consists of a bar on the side of  
the screen. Any echo on the chart that appears inside this bar triggers  
this alarm.  
The last alarm is the Depth Alarm, which has both a Shallow and a  
Deep setting. Only the bottom signal will trigger this alarm. This is  
useful as an anchor watch, a shallow water alert or for navigation.  
Depth Alarms  
The depth alarms sound a tone when the bottom signal goes shallower  
than the shallow alarm's setting or deeper than the deep alarm's set-  
ting. For example, if you set the shallow alarm to 10 feet, the alarm will  
sound a tone if the bottom signal is less than 10 feet. It will continue to  
sound until the bottom goes deeper than 10 feet.  
The deep alarm works just the opposite. It sounds a warning tone if the  
bottom depth goes deeper than the alarm's setting. Both depth alarms  
work only off the digital bottom depth signals. No other targets will trip  
these alarms. These alarms can be used at the same time or individually.

Calibrate Speed  
The speed sensor can be calibrated to compensate for inaccuracies. Be-  
fore you change the setting, first calculate the percentage that the  
speed is off. You will enter this percentage in a moment.  
For example, if you figure the sensor is reading 10 percent faster than  
actual speed, you will enter – 10 in the calibration window. If the sen-  
sor is reading 5 percent slower than true speed, you will enter + 5 in  
the window.  
A good way to gauge your speed sensor's performance is to compare its  
reading with the ground speed measured by your unit's GPS functions.  
When you make a run to compare GPS ground speed to speed sensor  
speed, perform your test in relatively calm water free of current, if pos-  
sible. (Unless, of course, you are taking the current speed into consid-  
eration when making your calculation.) After you have a correction fig-  
ure, here's how to enter it:  
1. Press MENU|MENU|to SONAR SETUP|ENT|to CALIBRATE WATER  
SPEED|ENT.  
2. Enter the number you calculated earlier: press or to change the  
first character (+ or –), then press to move the cursor to the next  
number and repeat until the percentage is correct, then press EXIT.

Chart Speed  
The rate that echoes scroll across the screen is called the chart speed.  
The default is maximum; we recommend that you leave the speed set  
there for virtually all fishing conditions.  
However, you might consider experimenting with chart speed when you  
are stationary or drifting very slowly. You may sometimes achieve bet-  
ter images as you slow down the chart speed to match how fast you are  
moving across the bottom.  
If you are at anchor, ice fishing or fishing from a dock, experiment with  
a chart speed around 50 percent. If you are drifting slowly, try a chart  
speed around 75 percent. When you are stationary and a fish swims  
through the sonar signal cone, the image appears on the screen as a  
long line instead of a fish arch. Reducing the chart speed may result in  
a shorter line that more closely resembles a regular fish return.  
At left, Sonar Page menu with Chart Speed command selected.  
At right, Chart Speed Control Bar.  
If you do experiment with chart speed, remember to reset it to maxi-  
mum when you resume trolling or moving across the water at higher  
speed. To change chart speed:  
1. From the Sonar Page, press MENU|to CHART SPEED|ENT.  
2. The Chart Speed Control Bar appears. Press to decrease chart  
speed; press to increase chart speed.  
3. When it's set at the desired level, press EXIT.  
Depth Cursor  
The depth cursor consists of a horizontal line with a digital depth box  
on the right side. The numbers inside the box show the depth of the  
cursor.

placed in the lower half of the screen. This is called Auto Ranging and  
is part of the automatic function. However, depending upon the bottom  
depth and the current range, you can change the range to a different  
depth. To do this:

Depth Range - Upper and Lower Limits  
Virtually any segment of the water column can be displayed by using  
the upper and lower limit feature. This lets you pick the shallow and  
deep depth range limits that are shown on the screen, provided there is  
at least 10 feet between the upper and lower limit you select. For ex-  
ample, a range from 12 feet to 34 feet could be used.  
Changing the upper and lower limits gives you far greater control over  
the depth range. This feature lets you "zoom in" the display in almost  
unlimited combinations. Nearly any segment of the water column, from  
the surface to the bottom can be shown. This enlarges the sonar targets  
to best suit your fishing needs and water conditions.

FasTrack  
This feature automatically converts all echoes to short horizontal lines  
on the display's far right side. The graph on the rest of the screen con-  
tinues to operate normally. FasTrack gives you a rapid update of condi-  
tions directly under the boat. This makes it useful for ice fishing, or  
when you're fishing at anchor. When the boat is not moving, fish sig-  
nals are long, drawn out lines on a normal chart display. FasTrack con-  
verts the graph to a vertical bar graph that, with practice, makes a use-  
ful addition to fishing at a stationary location.

Fish I.D.(Fish Symbols & Depths)  
The Fish I.D. feature identifies targets that meet certain conditions as  
fish. The microcomputer analyzes all echoes and eliminates surface  
clutter, thermoclines, and other signals that are undesirable. In most  
instances, remaining targets are fish. The Fish I.D. feature displays  
fish symbols on the screen in place of the actual fish echoes.  
There are several fish symbol sizes. These are used to designate the  
relative size between targets. In other words, Fish I.D. displays a small  
fish symbol when it thinks a target is a small fish, a medium fish sym-  
bol on a larger target and so on.  
The sonar's microcomputer is sophisticated, but it can be fooled. It can't  
distinguish between fish and other suspended objects such as trotlines,  
turtles, submerged floats, air bubbles, etc. Individual tree limbs ex-  
tending outwards from a group of limbs is the hardest object for the  
Fish I.D. feature to distinguish from fish.  
You may see fish symbols on the screen when actually, there are no  
fish. The reverse is also true. The illustrations on the next page show  
how Fish I.D. can actually miss fish that are present.  
Does that mean Fish I.D. is broken? No — the feature is simply inter-  
preting sonar returns in a specific way to help take some of the work  
out of reading the screen. Remember: Fish I.D. is one of the many tools  
we provide so you can analyze your sonar returns for maximum fish  
finding information. This and other features can help you successfully  
"see" beneath the boat under varied water and fishing conditions. So,  
practice with the unit in both the Fish I.D. mode and without to become  
more familiar with the feature. The default for Fish I.D. is off.

FishReveal  
When displaying actual sonar returns, the FishReveal feature uses 10  
levels of gray tones to show fish targets hidden by surface clutter,  
thermoclines, weed beds and other cover.  
The normal mode of operation (with FishReveal turned off) shows the  
weakest echoes as black and the strongest echoes in light gray. Since  
all weak echoes are black, fish arches show boldly against the white  
background. The drawback is that all weak echoes – such as thermo-  
clines – are also emphasized. This can make it hard to distinguish fish  
signals inside thermoclines or other cover.  
In FishReveal mode, the weakest echoes are white and the strongest  
echoes are black. Echoes in between vary in gray in proportion to their  
signal strength. The Grayline control determines the range for black to  
white. Also note that when using FishReveal, we recommend that you  
turn off Auto Sensitivity and turn up Sensitivity to near maximum.

Frequency (Change Transducer Frequency)  
(LMS-480DF only)  
The LMS-480DF transducer operates with both 200 kHz and 50 kHz.  
The 200 kHz frequency has a 12° cone angle and the 50 kHz frequency  
has a 35° cone angle.  
The default frequency is 200 kHz, which is best for use in shallow water  
(about 300 feet or less). This frequency is the best choice for about 80  
percent of the fresh and salt water sport fishing applications. When you  
get into very deep salt water, 300 to 500 feet or deeper, the 50 kHz fre-  
quency is the best choice.  
The 200 kHz transducer will give you better detail and definition, but  
less depth penetration. The 50 kHz transducer will give you greater  
depth penetration, but a little less detail and less definition. (Remember,  
all sonar units typically read deeper in fresh water than in salt water.)  
There is a common exception to these rules of thumb. Some fishermen  
on freshwater lakes (or the ocean) using downriggers like to see them  
on the sonar. In many of those cases, you'll see a 50 kHz transducer  
frequency in use because the wider cone angle lets them watch the bait.

Grayline  
Grayline lets you distinguish between strong and weak echoes. It  
"paints" gray on targets that are stronger than a preset value. This al-  
lows you to tell the difference between a hard and soft bottom. For ex-  
ample, a soft, muddy or weedy bottom returns a weaker signal which is  
shown with a narrow or no gray line. A hard bottom returns a strong  
signal which causes a wide gray line.  
If you have two signals of equal size, one with gray and the other with-  
out, then the target with gray is the stronger signal. This helps distin-  
guish weeds from trees on the bottom, or fish from structure.  
Grayline is adjustable. Experiment with your unit to find the Grayline  
setting that's best for you.

Ping Speed & HyperScroll  
Ping Speed controls the rate at which the transmitter and transducer  
broadcast sonar sound waves — pings — into the water. The unit has a  
default ping speed of 50 percent. At normal boating speeds, this auto-  
matically provides enough return echoes to refresh the screen and scroll  
the chart at maximum chart speed.  
However, when you are running at high speeds, or just want the fastest  
possible screen update, you may want to use the HyperScrollfeature.  
When you change the Ping Speed to any setting greater than 50 per-  
cent, the unit automatically enters HyperScroll mode.  
These faster ping rates allow you to maintain a high-detail picture on  
the screen, and the screen refresh rate and chart scroll speed can keep  
pace with the boat as it moves quickly over the bottom terrain.  
When using HyperScroll, you may also need to manually decrease the  
sensitivity for optimum performance. Depending on water depth and  
other conditions, HyperScroll may cause a second bottom echo to return

to the transducer during the next ping cycle, or sounding. This can result  
in a large amount of clutter appearing on the screen. If this occurs, just  
decrease the sensitivity to a level that eliminates the clutter. When you  
turn HyperScroll off, you can return to your original sensitivity level.

played by the digital depth, chart depth scale, chart cursor or fish sym-  
bols is not the exact water depth. If the transducer is 1 foot below the  
surface, and the screen shows the water depth as 30 feet, then the ac-  
tual depth is 31 feet.  
On sailboats or other large vessels with deep drafts, the distance be-  
tween the transducer installation and the keel or lower engine unit can  
be several feet. In those cases, an inexact depth reading could result in  
grounding or striking underwater structure. The Keel Offset feature  
eliminates the need for the navigator to mentally calculate how much  
water is under his keel.  
Keel Offset lets you calibrate the digital depth, chart depth scale, chart  
cursor depth and fish symbol depth displayed on the screen. To calibrate  
the depth indicators, first measure the distance from the face of the  
transducer to the lowest part of the boat. In this example, we will use 3.5  
feet. This will entered as a negative 3.5 feet, which makes the depth indi-  
cators perform as if the transducer's lower in the water than it really is.  
1. Press MENU|MENU|to SET KEEL OFFSET|ENT.  
2. The Keel Offset dialog box appears. Press to change the plus (+)  
sign to a minus (–) sign.  
3. Press to the first number, then press to change the number to 3  
4. Press to the second number, then press to change the number to  
5, then press EXIT. The depth indicators now accurately show the depth  
of water beneath the keel.  
NOTE:  
If knowing the exact depth of water beneath the keel is less important,  
you can calibrate the depth indicators so that they show the actual wa-  
ter depth from surface to bottom. To do this, first measure the distance  
from the face of the transducer up to the surface (the water line on the  
boat). In this example, we will use 1.5 feet. This will be entered as a  
positive 1.5 feet, which makes the depth indicators perform as if the  
transducer's higher in the water than it really is.  
1. Press MENU|MENU|to SET KEEL OFFSET|ENT.  
2. The Keel Offset dialog box appears with a plus (+) sign at the  
front of the box.

Sensitivity & Auto Sensitivity  
The sensitivity controls the ability of the unit to pick up echoes. Sensi-  
tivity can be adjusted, because water conditions vary greatly. A low  
sensitivity level (from zero to 50 percent) excludes much of the bottom  
information, fish signals, and other target information.  
High sensitivity levels let you see this detail, but it can also clutter the  
screen with many undesired signals. Typically, the best sensitivity level  
shows a good solid bottom signal with Grayline and some surface clutter.  
Automatic Sensitivity  
The default sensitivity mode is automatic. The unit bases the sensitiv-  
ity level on water depth and conditions. When the unit is in the auto-  
matic mode, sensitivity is automatically adjusted to keep a solid bottom  
signal displayed, plus a little more power. This gives it the capability to  
show fish and other detail.  
However, situations occur when it becomes necessary to increase or de-  
crease the sensitivity. This typically happens when you wish to see  
more detail, so an increase in sensitivity is indicated. Or, wave action  
and boat wakes can create enough tiny air bubbles to clutter much of  
the water column. In that case, a decrease in sensitivity is indicated to  
reduce some of the clutter.  
The control bar used to adjust sensitivity up or down is the same  
whether the unit is in the automatic or manual mode. In automatic you  
can adjust sensitivity up to 100 percent but the unit will limit your  
minimum setting. In auto, the unit will continue to make small ad-  
justments, allowing for the setting you selected.  
In manual mode, you have complete control over sensitivity, with the  
ability to set it anywhere from zero to 100 percent. Once you select a  
level in manual, the unit will continue to use that exact sensitivity set-  
ting until you change it or revert to auto mode.  
To adjust sensitivity in auto mode:  
1. Press MENU|ENT.  
2. The Sensitivity Control Bar appears. Press to decrease sensitivity;  
press to increase sensitivity. When it's set at the desired level, press  
EXIT. (When you reach the maximum or minimum limit, a tone sounds.)

The bottom signal scrolls across the screen from right to left. Depth  
scales on the right side of the screen aid in determining the depth of  
targets. The line at the top of the screen represents the surface. The  
bottom depth and surface temperature (if equipped with a temperature  
sensor or a transducer with a temp sensor built in) show at the top left  
corner of the screen.  
The FasTrack™ display shows just to the right of the scale. This  
changes all echoes into short horizontal bars, replicating a flasher so-  
nar. The zoom bar on the far right shows the area that's zoomed when  
the zoom is in use. (See the Zoom section for more information.)

how the unit will work in the field.  
NOTE:  
If you turn on your unit before attaching a transducer, it may enter a  
demo mode. The words "demo mode" flash on the bottom of the  
screen and a sonar chart plays much like the simulator. Unlike the  
simulator, the demo mode is for demonstration only, and will auto-  
matically stop as soon as you turn on the unit with a transducer at-  
tached. The simulator will continue to function normally.  
Stop Chart  
If you are running multiple units on a boat or using this unit in a car,  
there are times when you may want to turn off the sonar. This com-  
mand turns off the sonar and stops the chart from scrolling. Sonar re-  
starts automatically each time you turn on your unit.  
Press MENU|to STOP CHART|ENT|EXIT.  
To turn on sonar and start the chart scrolling again, repeat the above step.

Sonar Menu with Stop Chart command selected. The box is unchecked,  
indicating that the chart is scrolling across the screen.  
Surface Clarity  
The markings extending downward from the zero line on the chart are  
called "surface clutter." These markings are caused by wave action,  
boat wakes, temperature inversion and more.  
The surface clarity control reduces or eliminates surface clutter signals  
from the display. It does this by changing the sensitivity of the receiver,  
decreasing it near the surface and gradually increasing it as the depth  
increases.  
There are three levels of surface clarity available: low, medium, or high.  
It can also be turned off. The default level is off.  
To adjust the Surface Clarity level:  
1. From the Sonar Page, press MENU|to SONAR FEATURES|ENT.

Zoom & Zoom Bar  
"Zooming" the display is a common, fast and easy method used to en-  
large small detail, fish signals and the bottom with its associated struc-  
ture. This unit lets you zoom the display quickly and easily by pressing  
the Zoom In key, ZIN.  
Pressing ZIN once doubles the size (2X) of all echoes on the screen.  
Pressing it again quadruples the size of the echoes (4X). The zoom bar  
on the far right side of the screen shows which echoes will be displayed  
on the screen when the ZIN key is pressed.  
For example, pressing the ZIN key once will enable a 2X zoom which  
will show all echoes that are between the top and bottom of the 2X  
zoom bar. Pressing the key again will give a 4X zoom and only the ech-  
oes between the top and bottom of the 4X bar will show on the screen.  
Press the Zoom Out key, ZOUT, to return the display to the normal mode.

Zoom Pan  
Your unit has the handy ability to quickly zoom in on any portion of the  
water column with just the touch of an arrow key. The Zoom Pan feature  
lets you rapidly move the zoomed area up and down to different depths.  
By "pointing" your zoom at different portions of the chart as it scrolls,  
you can get a good, close-up look at structure or cover below you.  
To use Zoom Pan, switch to a manual depth Range setting (see page 64)  
and turn on 2X or 4X Zoom. Then, simply press or to pan up and  
down the water column.

Section 5:  
Sonar Troubleshooting  
If your unit is not working, or if you need technical help, please use the  
following troubleshooting section before contacting the factory customer  
service department. It may save you the trouble of returning your unit  
for repair. For contact information, refer to the last page, just inside the  
back cover of this manual.  
Unit won't turn on:  
1. Check the power cable's connection at the unit. Also check the wiring.  
2. Make sure the power cable is wired properly. The red wire connects  
to the positive battery terminal, black to negative or ground.  
3. Check the fuse.  
4. Measure the battery voltage at the unit's power connector. It should  
be at least 10 volts. If it isn't, the wiring to the unit is defective, the  
battery terminals or wiring on the terminals are corroded, or the bat-  
tery needs charging.  
Unit freezes, locks up, or operates erratically:  
1. Electrical noise from the boat's motor, trolling motor, or an accessory  
may be interfering with the sonar unit. Rerouting the power and trans-  
ducer cables away from other electrical wiring on the boat may help.  
Route the sonar unit's power cable directly to the battery instead of  
through a fuse block or ignition switch  
2. Inspect the transducer cable for breaks, cuts, or pinched wires.  
3. Check the transducer and power connector. Make sure it's securely  
plugged in to the unit.  
Weak bottom echo, digital readings erratic, or no fish signals:  
1. Make sure the transducer is pointing straight down. Clean the face of  
the transducer. Oil, dirt and fuel can cause a film to form on the trans-  
ducer, reducing its effectiveness. If the transducer is mounted inside the  
hull, be sure it is shooting through only one layer of fiberglass and that it  
is securely bonded to the hull. When attaching a transducer to the inside  
of a hull, ONLY use the epoxy available from LEI (order information is  
inside the back cover). Do NOT use RTV silicone rubber adhesive or any  
other type of epoxy. The LEI epoxy is specially formulated so that it will  
cure properly for shoot-through applications.  
2. Electrical noise from the boat's motor can interfere with the sonar.  
This causes the sonar to automatically increase its discrimination or  
noise rejection feature. This can cause the unit to eliminate weaker  
signals such as fish or even structure from the display.  
95  
Download from Www.Somanuals.com. All Manuals Search And Download.  
3. The water may be deeper than the sonar's ability to find the bottom.  
If the sonar can't find the bottom signal while it's in the automatic  
mode, the digital sonar display will flash continuously. It may change  
the range to limits far greater than the water you are in. If this hap-  
pens, place the unit in the manual mode, then change the range to a  
realistic one, (for example, 0-100 feet) and increase the sensitivity. As  
you move into shallower water, a bottom signal should appear.  
4. Check the battery voltage. If the voltage drops, the unit's transmitter  
power also drops, reducing its ability to find the bottom or targets.  
Bottom echo disappears at high speeds or erratic digital read-  
ing or weak bottom echo while boat is moving:  
1. The transducer may be in turbulent water. It must be mounted in a  
smooth flow of water in order for the sonar to work at all boat speeds. Air  
bubbles in the water disrupt the sonar signals, interfering with its ability  
to find the bottom or other targets. The technical term for this is cavitation.  
2. Electrical noise from the boat's motor can interfere with the sonar.  
This causes the sonar to automatically increase its discrimination or  
noise rejection feature. This can cause the unit to eliminate weaker  
signals such as fish or even structure from the display. Try using resis-  
tor spark plugs or routing the sonar unit's power and transducer cables  
away from other electrical wiring on the boat.  
No fish arches when the Fish I.D. feature is off:  
1. Make sure the transducer is pointing straight down. This is the most  
common problem if a partial arch is displayed.  
2. The sensitivity may not be high enough. In order for the unit to dis-  
play a fish arch, it has to be able to receive the fish's echo from the time  
it enters the cone until it leaves. If the sensitivity is not high enough,  
the unit shows the fish only when it is in the center of the cone.  
3. Use the Zoom feature. It is much easier to display fish arches when  
zoomed in on a small range of water than a large one. For example, you  
will have much better luck seeing fish arches with a 30 to 60 foot range  
than a 0 to 60 foot range. This enlarges the targets, allowing the dis-  
play to show much more detail.  
4. The boat must be moving at a slow trolling speed to see fish arches.  
If the boat is motionless, fish stay in the cone, showing on the screen as  
straight horizontal lines.  
NOISE  
A major cause of sonar problems is electrical noise. This usually ap-  
pears on the sonar's display as random patterns of dots or lines. In se-  
vere cases, it can completely cover the screen with black dots, or cause  
the unit to operate erratically, or not at all.  
96  
Download from Www.Somanuals.com. All Manuals Search And Download.  
To eliminate or minimize the effects of electrical noise, first try to de-  
termine the cause. With the boat at rest in the water, the first thing  
you should do is turn all electrical equipment on the boat off. Make sure  
the engine is also off. Turn your sonar on, then turn off Noise Reject  
[also known as the ASP feature (Advanced Signal Processing)]. Sensi-  
tivity should be set at 90-95 percent. There should be a steady bottom  
signal on the display. Now turn on each piece of electrical equipment on  
the boat and view the effect on the sonar's display. For example, turn  
on the bilge pump and view the sonar display for noise. If no noise is  
present, turn the pump off, then turn on the VHF radio and transmit.  
Keep doing this until all electrical equipment has been turned on, their  
effect on the sonar display noted, then turned off.  
If you find noise interference from an electrical instrument, trolling mo-  
tor, pump, or radio, try to isolate the problem. You can usually reroute  
the sonar unit's power cable and transducer cable away from the wiring  
that is causing the interference. VHF radio antenna cables radiate  
noise when transmitting, so be sure to keep the sonar's wires away  
from it. You may need to route the sonar unit's power cable directly to  
the battery to isolate it from other wiring on the boat.  
If no noise displays on the sonar unit from electrical equipment, then  
make sure everything except the sonar unit is turned off, then start the  
engine. Increase the RPM with the gearshift in neutral. If noise ap-  
pears on the display, the problem could be one of three things; spark  
plugs, alternator, or tachometer wiring. Try using resistor spark plugs,  
alternator filters, or routing the sonar unit's power cable away from  
engine wiring. Again, routing the power cable directly to the battery  
helps eliminate noise problems. Make sure to use the in-line fuse sup-  
plied with the unit when wiring the power cable to the battery.  
When no noise appears on the sonar unit after all of the above tests,  
then the noise source is probably cavitation. Many novices or persons  
with limited experience make hasty sonar installations which function  
perfectly in shallow water, or when the boat is at rest. In nearly all  
cases, the cause of the malfunction will be the location and/or angle of  
the transducer. The face of the transducer must be placed in a location  
that has a smooth flow of water at all boat speeds. Read your trans-  
ducer owner's manual or the Installation instructions (Sec. 2) in this  
manual for the best mounting position.

satellites and does not have a fix on its position. Center view shows sat-  
ellites being scanned. Right view shows satellite lock-on with a 3D posi-  
tion acquired (latitude, longitude and altitude), and WAAS reception.  
This screen shows a graphical view of the satellites that are in view. Each  
satellite is shown on the circular chart relative to your position. The point in  
the center of the chart is directly overhead. The small inner ring represents  
45° above the horizon and the large ring represents the horizon. North is at  
the top of the screen. You can use this to see which satellites are obstructed  
by obstacles in your immediate area if the unit is facing north.  
The GPS receiver is tracking satellites that are in bold type. The re-  
ceiver hasn't locked onto a satellite if the number is grayed out, there-  
fore it isn't being used to solve the position.  
Beneath the circular graph are the bar graphs, one for each satellite in  
view. Since the unit has twelve channels, it can dedicate one channel  
per visible satellite. The taller the bar on the graph, the better the unit  
is receiving the signals from the satellite.  
NOTE:  
One of the data display options for the Satellite Status page is "Po-  
sition Error" (horizontal position error), which can appear in one of  
the page's data boxes. If you turn on Position Error, it will show you  
the expected error from a benchmark location. In other words, if the  
Position Error box shows 50 feet, then the position shown by the  
unit is estimated to be within 50 feet of the actual location.  
103

This also gives you an indicator of the fix quality the unit currently  
has. The smaller the position error number, the better (and more ac-  
curate) the fix is. If the position error flashes dashes, then the unit  
hasn't locked onto the satellites, and the number shown isn't valid.  
(For details, see the Customize Page Displays entry in Sec. 8.)  
The Satellite Status Page has its own menu, which is used for setting  
various options. (Options and setup are discussed in Sec. 8). To access  
the Satellite Status Page Menu, from the Status Page, press MENU.

following figure. Your ground speed, track, distance and bearing to  
waypoint, and course are all shown digitally on this screen.  
NOTE:  
Remember, when the Speed, Track and Position information dis-  
plays are flashing, satellite lock has not been achieved and no posi-  
tion fix has been determined. A question mark will also flash on the  
present position arrow in the center of the compass rose.  
Speed (ground speed) is the velocity you are making over the ground. (If  
you wish, you can customize the Speed data box to display Closing  
Speed instead. Closing Speed is also known as velocity made good. It's  
the speed that you're making toward the waypoint. For instructions,  
see the Customize Page Displays entry in Sec. 8.)  
Track is the heading, or the current direction you are actually travel-  
ing. Bearing is the direction of a line-of-sight from your present position  
to the destination. No matter what direction you are steering, the  
Bearing window shows the compass direction straight to the destina-  
tion from your location at the moment. Distance shows how far it is to  
the waypoint you're navigating toward.  
The Off Course window shows the current cross track error. This shows  
the distance you are off-course to the side of the desired course line. The  
course line is an imaginary line drawn from your position when you  
started navigating to the destination waypoint. The course line is shown on  
the Navigation Page screen (and the Map Page screen) as a dotted line.

The cross track error range is shown on the compass rose as a wide,  
white, corridor enclosing the course line. The outer edges of this white  
corridor represent lines that show the current cross track error range.  
The default for the cross track error range is 0.20 miles.  
For example, if the present position symbol touches the right cross  
track error line, then you are 0.20 miles to the right of the desired  
course. You need to steer left to return to the desired course. You can  
use the ZIN or ZOUT keys to change the cross track error range.  
A circular symbol depicting your destination (waypoint) appears on the  
screen as you approach the waypoint, as shown on the screen in the  
preceding figure.  
Travel Time is the time that it will take to reach your destination at  
your present closing speed. (You can also customize the time data box  
to show Arrival Time instead. Arrival Time is the local time it will be  
when you arrive at the destination, based upon your present closing  
speed and track.)  
In the preceding example figure, the driver is headed west (a 265º  
track) toward a waypoint 265º (bearing) away. The cross track error  
range (white corridor) is 0.20 miles either side of the course. The driver  
is headed toward trail waypoint 4, which is 0.3 miles away. The vehicle  
is right on course. Traveling at a speed of 8 mph, the driver will arrive  
at the waypoint in 2 minutes, 17 seconds.  
The Navigation Page has its own menu, which is used for some ad-  
vanced functions and for setting various options. (Options and setup  
are discussed in Sec. 8). To access the Navigation Page Menu, from the  
Navigation Page, press MENU.  
Map Page  
The Map Page screens show your course and track from a "bird's-eye"  
view. By default, this unit shows the map with north always at the top  
of the screen. (This can be changed. See the topic Map Orientation, in  
Sec. 8.) If you're navigating to a waypoint, the map also shows your  
starting location, present position, course line and destination. You  
don't have to navigate to a waypoint, however, to use the map.  
Map Page is the default screen that appears when you turn on the unit.  
To get to the Map Page from another page: Press PAGES|or to  
MAP|EXIT. When the Map Page is displayed, a screen similar to the fol-  
lowing figures appears.

The arrow in the center of the screen is your present position. It points  
in the direction you're traveling. The solid line extending from the back  
of the arrow is your plot trail, or path you've taken.  
The map zoom range is the distance across the screen. This number  
shows in the lower right corner of the screen. In the first of the follow-  
ing example figures, the range is 4,000 miles from the left edge of the  
map to the right edge of the map.  
The Zoom In and Zoom Out keys zoom the map to enlarge or reduce its  
coverage area and the amount of mapping detail shown. There are 39  
available map zoom ranges, from 0.02 miles to 4,000 miles.  
Far left, Map Page opening screen. Center, zoomed to 100 miles and  
right, zoomed to 10 miles. Over Zoomed means you have reached the  
detail limits in an area covered only by the basic background map.  
Zooming in any closer will reveal no more map details because a high-  
detail custom map has not been loaded on the MMC for this area.  
If you're using only the factory-loaded background map, the maximum  
zoom range for showing additional map detail is 20 miles. You can con-  
tinue to zoom in closer, but the map will simply be enlarged without  
revealing more map content (except for a few major city streets.) Load  
your own high-detail custom map made with MapCreate (or a pre-made  
FreedomMap from LEI), and you can zoom in to 0.02 miles with mas-  
sive amounts of accurate map detail.

Map Pages with high-detail MapCreate map of an urban area loaded on  
the MMC. At left, arterial streets appear at the 4 mile zoom range, with a  
few Point of Interest icons visible. Center, numerous dots representing  
Points of Interest are visible at the 2 mile range, along with minor  
streets. Right, at the 0.4 mile zoom, you can see an interstate highway  
with an exit, major and minor streets as well as Point of Interest icons.  
Background map vs. MapCreate map content  
The background map includes: low-detail maps of the whole world (con-  
taining cities, major lakes, major rivers, political boundaries); and me-  
dium-detail maps of the United States.  
The medium-detail U.S. maps contain: all incorporated cities; shaded  
metropolitan areas; county boundaries; shaded public lands (such as  
national forests and parks); some major city streets; Interstate, U.S.  
and state highways; Interstate highway exits and exit services informa-  
tion; large- and medium-sized lakes and streams; and more than 60,000  
navigation aids and 10,000 wrecks and obstructions in U.S. coastal and  
Great Lakes waters  
MapCreate custom maps include massive amounts of information not  
found in the background map. MapCreate maps contain the searchable  
Points of Interest database, all the minor roads and streets, all the  
landmark features (such as summits, schools, radio towers, etc.); more  
rivers, streams, smaller lakes and ponds and their names.  
What's more important is the large scale map detail that allows your  
GPS unit to show a higher level of position accuracy. For example, the  
background map would show you the general outline and approximate  
shape of a coastline or water body, but the higher detail in MapCreate  
shows the shoreline completely and accurately (finer detail). Many  
smaller islands would not be included in the background map, but are,  
of course, in MapCreate.

When the map is zoomed out far enough, most POIs appear as square  
dots. As you zoom in closer, the symbols become readable icons. In the  
0.2 mile zoom example at right, the cursor has selected the Cupps Café  
POI, which triggers a pop-up box with the POI name. This pop-up box  
works on POIs at any zoom range.  
Tip:  
In some urban areas, businesses are so close to one another that  
their POI icons crowd each other on the screen. You can reduce  
screen clutter and make streets and other map features easier to  
see by simply turning off the display of POIs you're not watching  
for. (To see how, check the text on Map Detail Category Selection,  
page 158. It shows how to use the Map Categories Drawn menu to  
turn individual POI displays off and on.) Even though their display  
is turned off, you can still search for POIs and their icons will pop-  
up when your unit finds them for you.  
The Map Page has its own menu, which is used for several functions  
and for setting various options. To access the Map Page Menu, from the  
Map Page, press MENU.  
The Pages Menu also offers several map display options under the Map  
Page category. To access them, press PAGES|or to MAP|to Op-

Basic GPS Quick Reference  
Start outdoors, with a clear view of the open sky. As you practice, try  
navigating to a location at least a few blocks away. While you're learning,  
navigation in too small an area will constantly trigger arrival alarms.  
1. Connect the unit to electric power and the antenna module. Make sure  
the MMC is in. (See complete installation details beginning on page 13.)  
2. To turn on the unit, press and release PWR key.  
3. Opening screen displays map of North America at the 4,000 mile  
zoom range. Rotate through the four main Page screens (Map Page,  
Satellite Status Page, Navigation Page and Sonar Page) by pressing  
PAGES|or to select Page Name|EXIT. Switch Pages to display Sat-  
ellite Status Page.  
4. Wait while unit locates satellites and calculates current position. Process  
is visible on Satellite Page. This takes an average of 1 minute or less under  
clear sky conditions (unobstructed by terrain or structures.) When the unit  
acquires position, a tone sounds and a position acquired message appears.  
5. With position acquired, press PAGES key to display Map Page, which  
shows a bird's eye view of the earth. You can move around the map by:  
Zoom in closer to see greater detail: press ZIN (zoom in key.)  
Zoom out to see more area, less detail: press ZOUT (zoom out key.)  
Scroll map north, south, east or west using arrow keys ↑ ↓ → .  
To stop scrolling and return to current position on map, press EXIT key.  
6. Set a waypoint (Wpt 001) at your current position so you can navigate  
back here: press WPT|WPT. Waypoint symbol and "001" appears.  
7. Zoom/scroll map to find a nearby object or location to go to. Use ar-  
row keys to center cursor cross-hair over the map object or location.  
8. Navigate to the selected destination: press MENU|ENT|EXIT. Follow dot-  
ted course line on Map Page or compass bearing arrow on Navigation Page.  
9. At destination, Arrival Alarm goes off; to clear it, press EXIT. Cancel  
navigation: press MENU|MENU|to CANCEL NAVIGATION|ENT|to YES|ENT.  
10. Return to Wpt 1 by Navigate To Waypoint or Backtrack Trail. To

Find Your Current Position  
Finding your current position is as simple as turning the unit on. Un-  
der clear sky conditions, the unit automatically searches for satellites  
and calculates its position in approximately one minute or less.  
NOTE:  
"Clear sky" means open sky, unobstructed by terrain, dense foliage  
or structures. Clouds do not restrict GPS signal reception.  
If for some reason satellite acquisition takes longer, you may be inside  
a structure or vehicle or in terrain that is blocking signal reception. To  
correct this, be sure you are positioned so that the unit's antenna mod-  
ule has as clear a view of the sky as possible, then turn the unit off and  
back on again.  
Moving Around the Map: Zoom & Cursor Arrow Keys  
The map is presented from a bird's eye view perspective. The current  
zoom range shows in the lower left corner of the screen.  
1. Press the ZIN key (zoom in) to move in closer and see greater detail in  
a smaller geographic area.  
2. Press the ZOUT key (zoom out) to move farther away and see less map  
detail, but a larger geographic area.  
When you are traveling, the map will automatically move as you move.  
This keeps your current location roughly centered on the screen.  
You can manually pan or scroll the map northward, southward, east-  
ward or westward by using the arrow keys, which launch the cross-hair  
map cursor. This allows you to look at map places other than your cur-  
rent position. To clear the cursor, press EXIT, which jumps the map  
back to the current position or the last known position.  
Tip:  
Use the cursor to determine the distance from your current position  
(or last known position, when working indoors) to any map object or  
location. Simply use the arrow keys to position the cursor over the  
object or place. The distance, measured in a straight line, appears  
in the popup data box. Press EXIT to clear the cursor.

Selecting Any Map Item With the Cursor  
1. Use the zoom keys and the arrow keys to move around the map and  
find the item you wish to select.  
2. Use the arrow keys and center the cursor cross-hair on the desired ob-  
ject. On most items, a pop-up box will give the name of the selected item.  
Tip:  
This unit has an extremely handy Cursor Undo feature that lets  
you instantly return to the previous location you were looking at  
without scrolling. It works like this: Use the cursor (arrow keys) to  
scroll the map to some far away location or waypoint. Press EXIT to  
clear the cursor and jump back to your current position on the map.  
When you want to take another peek at that distant place, just  
press EXIT again. You can use this trick to toggle between your cur-  
rent position and your destination without a lot of scrolling.  
Searching  
Now that you've seen how the unit can find where you are, let's search  
for something somewhere else. Searching is one of the most powerful  
features in the Lowrance GPS product line.  
In this example, we'll look for the nearest fast-food restaurant. For more  
information on different types of searches, refer to Sec. 9, Searching.  
NOTE:  
This example requires the Point of Interest (POI) database included  
with a high detail MapCreate 6 custom map.  
After the unit has acquired a position:  
1. Press WPT|to POI-RESTAURANTS.  
114  
Download from Www.Somanuals.com. All Manuals Search And Download.  
2. You could search the entire restaurant category, but in this example  
we will narrow our search. Press to SUBCATEGORY column|to FAST  
FOOD CHAINS|ENT|to NEAREST|ENT.  
3. The unit says it is calculating, then a list of restaurants appears,  
with the closest at the top of the list, and the farthest at the bottom of  
the list. The nearest is highlighted.  
Find Waypoint Menu, left; Category Selection menu, center; and list of  
the nearest restaurants, right.  
4. If you wish, you could scroll or here to select another restaurant,  
but for now we will just accept the nearest one. Press ENT.  
5. The POI information screen appears. (This is how you can use this  
unit as a business phone directory!) If you wanted to navigate there,  
you could press Enter, since the Go To Waypoint command is high-  
lighted. But we just want to see it on the map, so press to FIND ON  
MAP|ENT.

7. To clear the search and return to the last page displayed, press  
EXIT|EXIT|EXIT|EXIT. (Before you completely exited out of the Search  
menus, you could have gone looking for another place.)  
NOTE:  
Search works from mapping and POI data loaded in the unit. If you  
do not have a high-detailed custom map (containing POI data) for  
the area you are searching loaded on the MMC, you may not find  
anything.  
Set a Waypoint  
A waypoint is simply an electronic "address," based on the latitude and  
longitude of a position on the earth. A waypoint represents a location,  
spot, or destination that can be stored in memory, then be recalled and  
used later on for navigation purposes.  
You can create a waypoint at the cursor position on the map, or at your  
current position while you are navigating. You can create a waypoint at  
any location by manually entering the position's latitude and longitude.  
You can copy waypoints from your unit to your personal computer with  
MapCreate software. When you want to repeat a trip, these archived  
waypoints can be reloaded into your GPS unit.

To create and save a Waypoint:  
These first two techniques use the Quick Save method, the fastest and  
easiest way to create a waypoint.  
Create Waypoint at Current Position  
While you are traveling, press WPT|WPT. The waypoint is saved and  
automatically given a name with a sequential number, such as "way-  
point 003." The waypoint symbol and number appear on the map.

WPT twice to call up Find Waypoint screen (seen in Step 2) and set a  
point. Step 3: a message says the waypoint has been saved. Step 4: ve-  
hicle continues on its way; number waypoint symbol is visible on map.  
NOTE:  
The Quick Save method uses the default waypoint symbol until you  
edit an existing waypoint and change its symbol. (Edit Waypoint  
Symbol is described in Sec. 7.) After you have changed a waypoint  
symbol, the unit will remember the one you chose and use it the

next time you "quick save" a waypoint. To revert back to the default  
symbol, edit a waypoint and choose the original symbol, or use the  
Reset Options command (described in Sec. 8).  
Create Waypoint on Map  
1. Use the arrow keys to move the cursor to the place where you want  
to make a waypoint.  
2. Press WPT|WPT. The waypoint is saved and automatically given a  
name with a sequential number, such as "waypoint 001." The waypoint  
symbol and number appear on the map.  
Create Waypoint by Entering a Position  
1. Press WPT|to SUBCATEGORY column|to NEW|ENT.  
2. Press to ENTERED POSITION|ENT|to CREATE|ENT.  
3. Press to LATITUDE|ENT. Enter the latitude by pressing or to  
change the first character, then press to the next character and re-  
peat until the latitude is correct. Press ENT.  
4. Press to LONGITUDE|ENT. Enter the longitude by pressing or to  
change the first character, then press to the next character and repeat  
until the longitude is correct. Press ENT, then EXIT|EXIT to return to the  
previous page display. The waypoint is saved and automatically given a  
name with a sequential number, such as "waypoint 001." The waypoint  
symbol and number appear on the map and in the waypoint list.  
Navigate To a Waypoint  
You can select any waypoint visible on the Map Page with the cursor,  
then use the Navigate to Cursor command (we'll describe how later in  
this section.) However, you can avoid scrolling the map to pick your  
waypoint if you use the Find Waypoint commands:  
1. Press WPT|to SAVED|ENT. To look up the nearest waypoint, press  
to NEAREST|ENT; or, to look by name (and scroll through the entire  
waypoint list), press ENT. For this example, look by name.  
2. If your waypoint list is a long one, you can spell out the waypoint name  
in the FIND BY NAME box to search for it. (Press or to change the first  
character, then press to move the cursor to the next character and re-  
peat until the name is correct, then press ENT to jump to the list below.)  
3. If the list is short, you can jump directly to the FIND IN LIST box by  
pressing ENT. Use or to select the waypoint name, press ENT and the  
waypoint information screen appears with the GO TO command selected.  
4. To begin navigating to the waypoint, press ENT.

Set Man Overboard (MOB) Waypoint  
One of boating's most terrifying events is having a friend or family  
member fall overboard. This situation can be deadly on any body of wa-  
ter — fresh or salt. It's particularly dangerous at night or if you're out  
of sight of land. Of course, the first thing to do is remain calm and then  
use all standard safety procedures to rescue the person.  
This unit has a man overboard feature that shows navigation data to  
the location where the feature was activated. To activate it, press the  
ZOUT and ZIN keys at the same time. Your position at the time these  
keys are pressed is used as the man overboard position.  
Caution:  
Saving a new "Man Overboard" waypoint will overwrite and  
erase the previous "Man Overboard" waypoint.  
Navigate Back to MOB Waypoint  
Find your way back to the accident position with the Navigation Page  
or Map Page. When MOB is activated, the Navigation Page automati-  
cally shows the compass rose with its bearing arrow pointing toward  
the man overboard position, and the destination name says "Going To  
Man Overboard." The Map Page displays a Man Overboard waypoint,  
represented by a human figure, and the steering arrow points where to  
steer to reach that position.

vents the inadvertent loss of the current Man Overboard position.  
To cancel navigation to MOB, press MENU|MENU|to CANCEL NAVIGA-  
TION|ENT|to YES|ENT. The unit stops showing navigation information.  
Navigate to Cursor Position on Map  
The GO TO CURSOR command: navigates to the current cursor position on  
the map. It's a quick and handy way to navigate to anything you can  
see on the map display.  
1. Use the cursor (controlled by the arrow keys) with the zoom in and  
zoom out keys to maneuver around the map until you find a location  
you want to go to.  
2. Center the cursor over the location to select it. See the example in  
the following figure. (Many map items such as waypoints, Points of In-  
terest, towns, etc. can be "selected," and appear "highlighted" with a  
pop-up box. Other features, such as a river or a street intersection will  
not appear "highlighted," but the cursor will take you to those locations  
just the same.)  
120

Navigate to cursor. In this example, the cursor has selected the town of  
Oologah, Oklahoma.  
3. Press MENU|ENT and the unit will begin navigating to the cursor lo-  
cation.  
The Map Page will display a dotted line from your current position to the  
cursor position. The Navigation Page displays a compass rose showing  
navigation information to your destination. See the following examples.  
The 15-mile zoom figure at left clearly shows the dotted course line  
connecting your current position to your destination. The 40-mile  
zoom, center, shows both current position and destination on screen.  
The Navigation Page, right, will also show navigation information.  
To stop navigating to the cursor, use the Cancel Navigation command:  
press MENU|MENU|to CANCEL NAVIGATION|ENT|to YES|ENT. The unit  
stops showing navigation information.  
Navigate to a Point of Interest  
For POIs that are in view on the map, you can easily use the Navigate  
to Cursor command above; just use the cursor to select the POI.

The other method involves searching for POIs with the Find Waypoint  
command, launched with the WPT key. (See the searching example ear-  
lier in this section, or turn to Sec. 9, Searching, for detailed instructions  
on POI searches.)  
After you have looked up an item with the Find Waypoint command,  
use or to make sure the GO TO WAYPOINT command is highlighted at  
the top of the screen, then press ENT. The unit begins showing naviga-  
tion information to the item.  
To cancel navigation, press MENU|MENU|to CANCEL NAVIGATION|ENT|←  
to YES|ENT. The unit stops showing navigation information.  
Creating and Saving a Trail  
A trail, or plot trail, is a string of position points plotted by the unit as  
you travel. It's a travel history, a record of the path you have taken.  
Trails are useful for repeating a journey along the same track. They are  
particularly handy when you are trying to retrace your trip and go back  
the way you came. On the screen, trails are represented by a solid line  
extending from the back of the current position arrow.  
The unit is set at the factory to automatically create and record a trail  
while the unit is turned on. The unit will continue recording the trail  
until the length reaches the maximum trail point setting (default is  
2,000, but the unit can record trails 9,999 points long). When the point  
limit is reached, the unit begins recording the trail over itself.  
By default, the trail flashes once a second, making it easier to see against  
the background map. With the default auto setting, this unit creates a  
trail by placing a dot (trail point) on the screen every time you change di-  
rections. (The methods used for creating a trail and the trail update rate  
can both be adjusted or even turned off. See Sec. 8 for Trail Options.)  
To preserve a trail from point A to point B, you must "turn off" the trail

Navigating Trails  
There are three methods for following a trail: visual trailing, navigating  
a trail (forward) and backtracking a trail (backward). Try each method  
to see which you prefer.  
Visual trailing is the simplest method. It uses only the Map Page and  
requires no menu commands at all. The technique works the same if  
you are running a trail forward (from start to end) or backward (from  
end to start.) However, visual trailing provides no navigation informa-  
tion during the trip, such as the time to your destination.  
124  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The other two methods provide a full range of navigation data and work  
with both the Map Page and Navigation Page. The only difference be-  
tween them is "navigating a trail" follows a trail forward (from start to  
end) while "backtracking" follows a trail in reverse (from end to start.)  
When hiking at walking speed with a hand-held GPS, we often just use  
visual back trailing because it is a bit better at following each little  
turn on a foot path. At faster speeds, such as the highway or on the wa-  
ter, the Navigate Trail and Backtrack Trail commands are handy.  
Visual Trailing  
1. On the Map Page, zoom (ZIN or ZOUT) so your flashing trail is visible.  
2. Begin moving and watch the Map Page. Simply walk or steer so that  
your current position arrow traces along the trail you have just made.  
Tip:  
Generally, when using this method, the smaller the zoom range, the  
more accurately you will be able to steer along the trail.  
Navigate a Trail (forward)  
The following figures illustrate the menu sequence for navigating a  
trail.  
1. Press MENU|MENU|to MY TRAILS|ENT.  
2. Press |to enter the Saved Trail list, then use or to select the  
desired Trail Name|ENT.  
3. Press to DELETE TRAIL|to NAVIGATE|ENT.  
4. Press to NAVIGATE|ENT. The unit begins showing navigation infor-  
mation along the trail.  
NOTE:  
If you are already located at or near the beginning of your trail, the  
arrival alarm will go off as soon as you hit Enter. Just press EXIT to  
clear the alarm and proceed.  
5. Now, begin moving and follow your unit.  
6. When you reach your destination, be sure to cancel your navigation:  
press MENU|MENU|to CANCEL NAVIGATION|ENT. The unit asks if you're  
sure; press |ENT.

Icons  
Icons are graphic symbols used to mark some location, personal point of  
interest or event. They can be placed on the map screen, saved and re-  
called later for navigation purposes. These are sometimes referred to as  
event marker icons. This unit has 42 different symbols you can pick  
from when creating an icon.  
Icons are similar to waypoints, but they do not store as much informa-  
tion (like names) as waypoints do. You can't use a menu to navigate to  
icons as you can with waypoints. (But, you can use the map cursor and  
navigate to any icon on the map.)  
You can create an icon at the cursor position on the map, or at your  
current position while you are navigating.

Routes  
A route is a series of waypoints, linked together in an ordered sequence,  
that's used to mark a course of travel. You can visualize a route as a  
133  
Download from Www.Somanuals.com. All Manuals Search And Download.  
string of beads: The beads represent waypoints and the string repre-  
sents the course of travel connecting waypoint to waypoint.  
The course from one waypoint to the next is a leg; routes are composed  
of one or more legs. The legs of all GPS routes are based on straight  
lines between waypoints.  
A route provides the automatic capability to navigate through several  
waypoints without having to reprogram the unit after arriving at each  
waypoint. Once programmed into the GPS unit, a route provides the  
option of navigating forward through the route waypoints or in reverse  
order (you can even begin navigating in the middle of a route!)  
Create and Save a Route  
You have the option of creating and editing a route in the unit, or you  
can make a route on your computer with our MapCreate 6 software.  
PC-created Routes  
MapCreate is the easiest method for preparing a route, simply because  
your PC's larger screen, keyboard and mouse are easier to manipulate  
than the unit.  
To load a MapCreate route into the unit, follow instructions in MapCre-  
ate's manual for creating a route and saving it as part of a GPS Data File  
(file format *.usr). Copy the GPS Data File to an MMC and insert the  
MMC in the unit. (See Sec. 2 for instructions on installing MMCs. To  
load the GPS Data File into the unit's memory, see the entry on Transfer  
Custom Maps & GPS Data Files in Sec. 6, Basic GPS Operations.)  
Routes Created in the Unit  
You can create a route by selecting existing waypoints from the way-  
point list or you can set a series of route waypoints on the map with  
cursor arrows and the Enter key. In this example, we'll create a route  
from the map.

(If you are starting at your current position or the current cursor posi-  
tion, you are already at the starting spot.)  
4. Set the first route waypoint: press ENT. In this example, we moved to  
the intersection of 11th Street and 145th E. Ave. to start our route to a  
public hunting area next to a river. (Creating this example route is il-

System & GPS Setup Options  
Alarms  
This unit has several GPS alarms. The factory default setting has all of  
these but the anchor alarm turned on. You can turn the alarms off and  
on and change their distance settings.  
You can set an arrival alarm to flash a warning message and sound a  
tone when you cross a preset distance from a waypoint. For example, if  
you have the arrival alarm set to .1 mile, then the alarm will flash a  
message when you come within .1 mile of the recalled waypoint.  
The off course alarm warns you when your track drifts too far to the  
right or left of the course line to the waypoint. For example, if the  
alarm is set to .1 mile, then the alarm flashes a message if you drift .1  
of a mile or more to the right or left of the line to the waypoint.  
The anchor alarm is triggered when you drift outside of a preset radius.  
Again, using the .1 mile as an example, if you're anchored and your  
boat moves more than .1 of a mile, the alarm will flash a message and  
sound a tone.  
Alarms command, left; Alarm menu, right.  
To change alarm settings:  
1. Press MENU|MENU|to ALARMS|ENT|ENT.  
2. Scroll or to select the desired category, then press ENT to check or  
clear the Enabled box. This turns the alarm on (checked) or off (un-  
checked.)

repeat until the name is correct.  
4. When your adjustments are finished, return to the last page dis-  
played by repeatedly pressing EXIT.  
IMPORTANT ALARM NOTES:  
Anchor Alarm - The anchor alarm may be triggered even when  
you're sitting still. This typically happens when using small (less  
than .05 mile) anchor alarm ranges.  
Arrival Alarm - If you set the arrival alarm's distance to a small  
number and you run a route (see the Navigate Routes segment),  
this unit may not show navigation data to the next waypoint, once  
you arrive at the first one, since you may not be able to come close  
enough to the first waypoint to trip the arrival alarm.  
Auto Satellite Search  
To lock onto the satellites, the GPS receiver needs to know its current  
position, UTC time and date. (Elevation [altitude] is also used in the  
equation, but it's rarely required to determine a position.) It needs this  
data so that it can calculate which satellites should be in view. It then  
searches for only those satellites.  
When your GPS receiver is turned on for the first time, it doesn't know  
what your position or elevation (altitude) is. It does know the current UTC  
time and date since these were programmed into it at the factory and an  
internal clock keeps the time while the unit is turned off. (If the time  
and/or date are incorrect, you can set it using the "Set Local Time" menu.)  
The unit begins searching for the satellites using the above data that it  
acquired the last time it was turned on. This probably was at the fac-  
tory. Since it's almost certain that you're not at our factory, it's proba-  
bly looking for the wrong satellites.  
If it doesn't find the satellites it's looking for after approximately one  
minute, it switches to Auto Search. The receiver looks for any satellite  
in the sky. Due to advanced technology, the auto search time has  
shrunk significantly from the early days of GPS.  
Once the unit locks onto the satellites, it should take less than a minute to  
find your position the next time it's turned on, provided you haven't moved  
more than approximately 100 miles from the last location it was used.

This unit can show a position in degrees (36.14952°); degrees, minutes  
and thousandths of a minute (36° 28.700'); or degrees, minutes, seconds  
and tenths of a second (36° 28' 40.9"). It can also show position in: UTM  
(Universal Transverse Mercator) projection; MGRS (Standard); MGRS  
(Standard + 10); Map Fix; Loran TD; British, Irish, Finnish, German,  
New Zealand, Swedish, Swiss, Taiwan and Greek.  
UTM's are marked on USGS topographic charts. This system divides  
the Earth into 60 zones, each 6 degrees wide in longitude.  
British, Irish, Finnish, German, New Zealand, Swedish, Swiss, Taiwan,  
and Greek grid systems are the national coordinate system used only in  
their respective countries. In order to use these grid systems, you must  
be in the respective country. This unit will pick the matching datum for  
you when you select the grid. See the entry on Map Datum Selection for  
more information.  
The Military Grid Reference System (MGRS) uses two grid lettering  
schemes, which are referred to as standard and standard + 10 MGRS  
on this unit. Your position and datum in use determines which one to  
use. If you use standard, and your position is off significantly, then try  
the alternate.  
NOTE: When the position format is changed, it affects the way all posi-  
tions are shown on all screens. This includes waypoints.

lecting "Setup Loran TD" at the bottom of the "Coordinate System"  
menu and select the ID. Press EXIT to erase this menu.  
Configure Loran TD menu.  
Map Fix  
Map Fix is used with charts or maps. This system asks for a reference  
position in latitude/longitude, which you take from a marked location  
on the map. It then shows the present position as distance on the map  
from that reference point.  
For example, if it shows a distance of UP 4.00" and LEFT 0.50", you  
then measure up four inches and to the left a half-inch from the refer-  
ence point on the map to find your location.  
To configure a map fix:  
To use this format, you need to follow these steps in order. First, take  
your map of the area and determine a reference latitude/longitude.  
(Note: in order for this system to work, the latitude/longitude lines  
must be parallel with the edge of the map. USGS maps are parallel,  
others may not be. Also, this works better with smaller scale maps,  
such as 1:24000.) The reference position can be anywhere on the map,  
but the closer it is to your location, the smaller the numbers will be  
that you'll have to deal with.  
Once you've decided on a reference position, you can save it as a waypoint.  
See the waypoint section for information on saving a waypoint. Save the  
reference position as a waypoint. Exit from the waypoint screens.

TURES|ENT. The GPS menus and pages are available once again.  
Initialize GPS  
This command is handy when you are practicing in simulator mode. (See  
the entry in this section for GPS Simulator.) In simulator mode, this  
command makes the unit operate as if it is sitting someplace other than  
its actual location. So, you and your unit could be located in Kansas City,  
but easily practice navigating in the ocean off Islamorada, Florida.  
1. Press MENU|MENU|to GPS SETUP|ENT|ENT.  
2. A message appears, telling you to move the cursor near the desired  
location and press ENT. When the message automatically clears, follow  
the message instructions.  
3. In a moment, your present position marker arrow appears on the  
map in the location you selected with the cursor. The unit will consider  
that spot as its last known position until changed by either a live satel-  
lite lock-on or a new simulator location.  
Map Auto Zoom  
This receiver has an auto zoom feature that eliminates much of the but-  
ton pushing that other brands of GPS receivers force you to make. It  
works in conjunction with the navigation features.  
First, start navigation to a waypoint. (See the waypoint section for  
more information on navigating to a waypoint.) Then, with the auto  
zoom mode on, the unit zooms out until the entire course shows, from  
the present position to the destination waypoint. As you travel toward  
the destination, the unit automatically begins zooming in — one zoom  
range at a time — always keeping the destination on the screen.

Map Overlays (Range Rings; Lat/Long Grid)  
The map screen can be customized with four range rings and/or grids  
that divide the plotter into equal segments of latitude and longitude.  
Range rings are handy for visually estimating distances on the map. The  
ring diameters are based on the current zoom range. For example: at the  
100 mile zoom, the screen will show two rings with your current position  
in the center. The large ring touching the left and right sides of the  
screen is 100 miles in diameter (same as the zoom range). The second  
smaller ring is 50 miles in diameter (always 1/2 the zoom range).  
The distance from your current position to the smaller ring (the ring's  
radius) is 25 miles (always 1/4 the zoom range). With the arrow keys  
and map cursor, you can scroll the map to see the third and fourth  
rings. In this example, the distance to the third ring is 75 miles and  
distance to the fourth ring is 100 miles from your current position.  
To set range rings: From the Map Page, press MENU|to MAP

Map Datum Selection  
Maps and charts are based on a survey of the area that's covered by the  
map or chart. These surveys are called "Datums." Maps that are cre-  
ated using different datums will show the same latitude/longitude in  
slightly different locations.  
All datums are named. The GPS system is based on the WGS-84 da-  
tum, which covers the entire world. Other datums may also cover the  
entire world, or just a small portion of it. By default, your position  
shows using the WGS-84 datum. However, it can show your position  
using one of 191 different datums. Different datums can be selected; to  
change the datum:

In Track Up mode, map shows "N" and arrow to indicate north.  
Map orientation at left is shown in north up and at right, track up.  
This is fine if you're always traveling due north. What you see to your  
left corresponds to the left side of the map, to your right is shown on  
the right side of the map, and so on. However, if you travel any other  
direction, the map doesn't line up with your view of the world.  
To correct this problem, a track-up mode rotates the map as you turn.  
Thus, what you see on the left side of the screen should always be to  
your left, and so on.  
Another option is course-up mode, which keeps the map at the same  
orientation as the initial bearing to the waypoint. When either the  
track-up or course-up mode is on, an "N" shows on the map screen to  
help you see which direction is north.

Position Pinning  
When you are standing still or moving at extremely slow speed, a GPS  
receiver can have trouble determining the direction you are traveling.  
In the past, this resulted in a "wandering" plot trail that moved around  
the map, even if you were standing still.  
The Position Pinning feature was developed so that when you stopped,  
the unit locked the present position on the GPS plotter until you moved  
a short distance or exceeded a very slow speed.  
165  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The command remains available in the unit's software, but we recom-  
mend that you leave it in the default off (unchecked) mode. The "wan-  
dering" plot trail issue has now been corrected by the Track Smoothing  
feature. Turning on Position Pinning could actually result in an inaccu-  
rate plot trail if you are moving around in a relatively small area. If you  
want to experiment with Position Pinning, the same instructions are  
used to turn the feature on (checked) and off (unchecked.)

Show WAAS Alarm  
When the signal is available, your unit will automatically use WAAS to  
boost the accuracy of the position fix. When the WAAS signal is lost or  
acquired, an alarm message appears. Since the U.S. government is still  
developing the WAAS system, it's not unusual for a GPS/WAAS re-  
ceiver to frequently lose and reacquire its lock on a WAAS satellite.  
That can result in the alarm repeatedly going on and off. If you want,  
you have the option of turning off the WAAS Acquired/Lost alarm with-  
out affecting how the unit uses WAAS. Here's how:  
1. Press MENU|MENU|to GPS SETUP|ENT|to SHOW WAAS ALARM.  
2. With the option highlighted, press ENT to uncheck it (turn off) and  
check it (turn on.) After the option is set, press EXIT|EXIT to return to

traveling in a straight line. Once you deviate from a straight line, the  
unit "drops" a plot point (trail waypoint) onto the trail. This conserves  
plot trail points. If a plot trail uses all of the available points allotted to  
it, the beginning points are taken away and placed at the end of the trail.

"We", "our", or "us" refers to Lowrance Electronics, Inc., the manufacturer of  
this product. "You" or "your" refers to the first person who purchases the prod-  
uct as a consumer item for personal, family, or household use. The Databases  
Limited Warranty applies to the one or more databases that your product may  
contain. We refer to each of these as a "Database" or together as the "Data-  
bases." Your product may thus include the "WBS Database" which contains  
worldwide background surface mapping data, the "SmartMap Database" which

We warrant to you that we have accurately compiled, processed, and repro-  
duced the portions of the source material on which the Databases are based.  
However, we are under no obligation to provide updates to the Databases, and  
the data contained in the Databases may be incomplete when compared to the  
source material. WE MAKE NO EXPRESS OR IMPLIED WARRANTY OF  
ANY KIND ABOUT THE ACCURACY OF THE SOURCE MATERIAL ITSELF,  
INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MER-  
CHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.  
If there is a defect in any Database, your exclusive remedy shall be, at our op-  
tion, either a refund of the price you paid for the product containing the defec-  
tive Database or a replacement of such product. WE WILL NOT UNDER ANY  
CIRCUMSTANCES BE LIABLE TO ANYONE FOR ANY SPECIAL, CONSE-  
QUENTIAL, INCIDENTAL, OR OTHER INDIRECT DAMAGE OF ANY KIND.  
Some states do not allow the exclusion or limitation of incidental or consequen-  
tial damages, so the above limitations or exclusions may not apply to you.  
This warranty does NOT apply in the following circumstances: (1) when the  
product has been serviced or repaired by anyone other than us; (2) when the  
product has been connected, installed, combined, altered, adjusted, or handled  
in a manner other than according to the instructions furnished with the prod-  
uct; (3) when any serial number has been effaced, altered, or removed; or (4)  
when any defect, problem, loss, or damage has resulted from any accident, mis-  
use, negligence, or carelessness, or from any failure to provide reasonable and  
necessary maintenance in accordance with the instructions of the owner’s man-  
ual for the product.  
We reserve the right to make changes or improvements in our products from  
time to time without incurring the obligation to install such improvements or  
changes on equipment or items previously manufactured.  
This warranty gives you specific legal rights and you may also have other rights  
which may vary from state to state.  
Your remedies under this warranty will be available so long as you can show in  
a reasonable manner that the defect occurred within one (1) year from the date  
of your original purchase, and we must receive your warranty claim no later  
than 30 days after such 1-year period expires. Your claim must be substanti-  
ated by a dated sales receipt or sales slip.
