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 dam-
age 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 commercial-quality 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 MapCreate 6, you have an incredible combination.
With a full VGA color display, recording capability and remarkable
resolution, you won't find another GPS/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 LCX-104C 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 sonar, right out of the box. This section features a one-page
Sonar Quick Reference. (If you've already jumped ahead and fig-
ured out how to install the unit yourself, and you just can't wait
any longer, turn to the Quick Reference on page 47 and head
for the water with your unit!)

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 unit's 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 103.
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 the unit's many advanced
navigation features. That brings us to Section 7, Advanced GPS Opera-
tions. This section contains the rest of the unit's GPS command func-
tions, organized in alphabetical order.
When you come to a GPS menu command on the 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 portion of Section 7.
This unit is ready to use right out of the box, but you can fine tune and
customize its 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 the unit's most remarkable
GPS capabilities — Searching. We'll introduce a search example in the
Basic GPS Operation section, but there are so many map items you can
search for, we had to give this function its own section in the manual! For
example, did you know your unit 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.
Now, if you're into the fine details, glance over the next segment on
specifications to see just how much sonar and GPS power your unit con-
tains. It's important to us (and our power users), but, if you don't care

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 Your 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 underwater 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:
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
5

(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 sonar unit 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 Your GPS Works
You'll navigate faster and easier if you understand how this unit scans
the sky to tell you where you are on the earth — and, where you're go-
ing. (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 unit as a small but powerful computer. (But don't
worry — we made the series easy to use, so you don't need to be a com-
puter expert to find your way!) The unit includes a keypad and a screen
with menus so you can tell it what to do. The screen also lets the unit
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 unit listens to signals from as many satellites as it can "see" above
the horizon, eliminates the weakest signals, then computes its location
in relation to those satellites. Once it figures its latitude and longitude,
the unit 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 every unit 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, MapCreate 6. 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 91.
Another portion of the unit'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
other Lowrance GPS or sonar/GPS units and even personal computers.
Your unit has one more thing in common with a personal computer.
Just as computers have a floppy disk drive for storing and exchanging
files, this unit has a slot for an MMC (MultiMedia Card) or SDC (Se-
cure Digital card) flash memory card. These solid-state memory devices
are about the size of a postage stamp, but can hold data ranging from 8
MB to 256 MB in size. (Compare that to a floppy disk's 1.44 MB capac-
ity!) The unit uses all that MMC space for two key GPS purposes. (The
MMC is also used to record sonar logs…see page 6.)
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 the unit's memory.
(NOTE: No matter where they come from, GPS Data Files must be
loaded from the MMC into memory before the unit 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 other Lowrance GPS or so-
nar/GPS units and personal computers. (For example, the exact same
7

MMC, custom map files and GPS data files can be used interchangea-
bly between your gimbal-mounted LCX-104C and the hand-held
iFINDER GPS receiver.)
The unit 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 con-
taining a map into the unit.
Introduction to GPS and WAAS
Well, now you know the basics of how the unit 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 naviga-
tion, 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.
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.
8
Download from Www.Somanuals.com. All Manuals Search And Download.
A minimum of three satellites are required to determine a 2D 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, this unit 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 the
unit 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 is plenty accurate for route navigation, but the U.S. Federal Avia-
tion Administration has special needs for aircraft traffic control that go
beyond basic GPS. The FAA has a plan under way to boost GPS per-
formance even further with its Wide Area Augmentation System, or
WAAS. This GPS add-on will include a time control element that will
help airliners fly closer together while avoiding collisions. In addition to
carefully spacing airplanes along travel corridors, WAAS will eventu-
ally make instrument landings and takeoffs more accurate as it re-
places existing aviation navigation systems.
Non-aviators can use WAAS signals to make their GPS navigation even
more accurate. Your unit receives both GPS and WAAS signals. How-
ever, WAAS has some limits you should know about.

First, the U.S. government has not completed construction of the WAAS
system, so it is not yet fully operational. The ground stations are in
place, but only a few of the needed WAAS satellites have been launched.
WAAS can boost 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 frequently 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.
10

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 this unit 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 unit's directions.
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.
Transducer Installation
These instructions will help you install your Skimmer transducer 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. Use
extreme care if mounting the transducer inside the hull, because once it
is epoxied into position, the transducer usually cannot be removed.
Remember, the transducer installation is the most critical part
of a sonar installation.
Recommended Tools and supplies
If you prefer the option of routing the cable through the transom, you
will need a 1" drill bit. A transom mount requires use of a high quality,
marine grade above- or below-waterline caulking compound. The fol-
lowing installation types also call for these recommended tools and re-
quired supplies (supplies are not included):
Single-frequency transom installations
Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flat-
head screwdriver. Supplies: none.
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.
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. Supplies: 100 grit sandpaper, good quality
epoxy adhesive.
Selecting a Transducer Location
1. The transducer must be placed in a location that has a smooth flow of
water at all times. If the transducer is to be mounted inside the hull,
then the chosen location must be in the 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
at speeds faster than 35 mph. Typically, a good location on alumi-
num boats is between the ribs closest to the engine.
14
Download from Www.Somanuals.com. All Manuals Search And Download.
2. The transducer should be installed with its face pointing straight
down, if possible.
3. If the transducer is mounted on the transom, make sure it doesn't inter-
fere 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 pre-
vent cavitation (bubble) interference with propeller operation.
4. 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

prevent the transducer from

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.

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
Typically, shoot-thru-hull installations give excellent high speed opera-
tion and good to excellent depth capability. There is no possibility of
damage from floating objects. It can't be knocked off when docking or
loading on the 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.
Second, the transducer angle cannot be adjusted for the best fish
arches. This can be a problem on some hulls that sit with the bow high
when at rest or at slow trolling speeds. Follow the procedure listed in
the shoot-thru-hull installation section at the end of this lesson to de-
termine 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
16

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.
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.
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.

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).

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 caulking compound.
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.
Partial fish arches

Transducer angles and their effects on fish arches.
If the arch slopes up – but not back down – then the front of the trans-
ducer is too high and needs to be lowered. If only the back half of the
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
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
23
Download from Www.Somanuals.com. All Manuals Search And Download.
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.
Fill with epoxy
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, 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.
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.
To choose the proper location for thru-hull mounting, anchor the boat in
60 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. Adjust the sensitivity and range controls until a sec-
ond bottom echo is seen on the display. (You will need to turn off both
automatic and ASP.) Don't touch the controls once they've been set.
Next, take the transducer out of the water and place it in the water in
the sump of the boat. Observe the sonar signal to see if there is a no-
ticeable decrease in sensitivity. The second bottom signal may disap-
pear and the bottom signal may decrease in intensity.
Move the transducer around to find the best location. If the sensitivity
control must be increased greatly to compensate, then the transducer
should be mounted on the outside of the hull. If not, then mark the lo-

Shoot-thru-hull Installation
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 surface of the hull must be flat so the entire
transducer face is in contact with the hull prior to bonding.
Spread epoxy here
Sand this surface
Epoxy transducer to hull.
2. Follow the instructions on the epoxy package and mix it thoroughly.
Do not mix it too fast, because it will cause bubbles to form in the ep-
oxy. Apply a small amount on the face of the transducer as shown
above, then spread a small amount onto the sanded area on the hull.
25
Download from Www.Somanuals.com. All Manuals Search And Download.
Place the transducer into the epoxy, twisting and turning it to force
any air bubbles out from under the transducer face. The face of the
transducer should be parallel with the hull, with a minimum amount
of epoxy between the hull and transducer. After the epoxy dries,
route the cable to the sonar unit.
Speed/Temperature Sensors
This unit accepts up to three temperature sensors which can monitor
surface water, live well, air and virtually any other temperature. If you
want to use more than one temperature sensor or a speed sensor, you
must purchase the optional MY-4X adapter cable. You also need to be
careful when purchasing the temperature sensors, because each tem-
perature sensor has its own fixed electronic "address." The sensors are
labeled "Water," "T-2" (or Temp-2) and "T-3" (or Temp-3).
The first "Water" temperature sensor is built into the transducer. This
is the sensor that measures surface water temperature. If you want two
(or more) temperature readings from other locations, you'll need to use
the proper sensors. For example, you can't use two additional T-3 sen-
sors. The sensors that fit this unit are:
•
TS-1X
This sensor will over-ride the temperature sensor
built into the transducer and over-ride the tem-
perature sensor in a ST-TGY combination sen-
sor. (This sensor is not recommended.)
•
•
•
•
TS-2X
TS-3X
SP-X
One sensor for "T-2" temperature display.
One sensor for "T-3" temperature display.
One speed sensor for "Speed" display.
ST-TGY
This combination sensor will provide speed and
temperature readings, but the temperature
reading will be displayed as the "Water" tem-
perature because it will over-ride the tempera-
ture sensor in the transducer. (This sensor is
not recommended.)
See the wiring diagram on the following page for temperature and
speed sensor combinations.

Optional Speed Sensor Installation
This unit can display speed and distance traveled; the feature requires
a speed sensor which may or may not come packaged with your unit. (If
you wish to purchase an optional additional sensor for your unit, refer
to the accessory 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 caulking compound.
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.
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
caulking compound to seal the screws. Make sure the sensor is flush
with the bottom 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 caulking compound. 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 in-line con-
nector on the MY-4X adapter cable. If you have any questions concern-
ing the installation of the sensor, please contact your local boat dealer.
GPS Antenna/Receiver Module
This unit's package includes the LGC-12w 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 extension
cable. This module can be mounted on a flat surface or pole, or a mag-
net is included for temporary mounting on any ferrous surface. (The
LGC-12s GPS module sold with earlier Lowrance equipment will work
with your unit, but it will not receive WAAS signals.)

You need to select an antenna installation location that has a clear, un-
obstructed view of the sky. After the module is installed, route the cable
to the unit, plug it in the center socket on the back and your system is
ready to use. See the module's instruction sheet, publication part num-
ber 988-0147-39, 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 recrea-
tional 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 an-
tenna module elsewhere on the vehicle for a clearer view of the sky.
Power Connections
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.
If possible, keep the power cable away from other boat or vehicle wir-
ing, 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. Make sure to attach the in-
line fuse holder to the red lead as close to the power source as possible.
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 6-amp fuse.

CAUTION:
Do not use this product without a 6-amp fuse wired into the power
cable! Failure to use a 6-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.
An optional 8-foot, CA-4 external power cable with a cigarette lighter
adapter is available from Lowrance.
NMEA/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 this unit and receive positioning information. The unit can ex-
change 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 its 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 LCX-104C). Lowrance offers
an optional DGPS receiver for your unit.
See the following diagrams for general wiring connections. Read your
other product’s owner’s manual for more wiring information.
NMEA/DGPS Wiring
To exchange NMEA or DGPS data, the unit has two NMEA 0183 version
2.0 communication ports. Com port one (Com-1) can be used to receive
NMEA format GPS data or DGPS data. Com-1 can also transmit NMEA
format GPS data to another device. Com-2 is for NMEA output only.
The three wires for the com port are combined with the two power
wires and the speaker wires to form the power/data cable (see the
drawing on page 33). Com-1 uses the yellow wire to transmit, the or-
ange wire to receive and the shield wire for signal ground. Com-2 uses
the blue wire for transmit.

Mounting the Unit: Bracket or In-Dash
You can install the unit on the top of a dash with the supplied gimbal
bracket. It can also be installed in the dash. For an in-dash mount, con-
sult the factory customer service department. Service contact informa-
tion is inside the back cover of this manual.
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 draw-
ing 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.

Once a location is determined, use the bracket as a template and mark
the mounting holes and the hole for the cables. Drill a 1-inch (25.4 mm)
hole in the dash for the power, transducer and antenna cables. Screw
the bracket to the mounting surface.
To pass all connectors through the 1" hole, first pass the transducer
connector up through the hole from under the dash, followed by any
accessory cables. Next, 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. Be sure to leave enough slack in the cables to
allow tilting the unit.
Attach the unit to the gimbal bracket using the supplied gimbal knobs
and washers, attach the cables and the unit is ready to use.
MMC or SDC Memory Card Installation
Your unit uses MultiMedia Cards 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 or SDC) to store data. The unit
can use up to two cards at the same time; an MMC and an SDC can be
used together at the same time.
NOTE:
Throughout this manual, we will use the term MMC, but just re-
member that your unit can use an MMC or SDC to store data.
Both of these solid-state flash memory devices are about the size of a
postage stamp. An SD card is slightly thicker than an MMC. As this
manual went to press, MMCs were available in storage capacities of 8
MB, 16 MB, 32 MB and 64 MB. SD cards were available in capacities of
8 MB, 16 MB, 32 MB, 64 MB, 128 MB and 256 MB.
Additional MMC cards are available from LEI Extras; see ordering in-
formation inside the back cover of this manual. MMCs and SD cards
are also available at many camera and consumer electronics stores.
The two MMC slots are located in compartments on the front of the
case. The water-proof compartment doors are located at the lower right
corner. The following figure shows a close-up of one compartment with
the door opened.

Switch Boxes
Two switch boxes are available for this unit. The SB-7X transducer
switch box switches two transducers to one sonar unit. The SB-8X trans-
ducer switch box switches two sonar units to one transducer.
If these accessories are not available from your dealer, see the acces-
sory ordering information on the inside back cover of this manual. Visit
our web site for a complete listing of all the available accessories for
your unit.
External Speaker
Your unit can play sounds to an external speaker. This feature can be
convenient any time you are away from the unit – especially in a larger
boat – but still want to hear its alarms. You might install a small
speaker at the stern of your boat so you won't miss a dangerous Shal-
low Alarm while fishing, or put one in your galley so you can hear the
GPS Arrival Alarm.

You can purchase an external speaker at your nearest audio electronics
store. The unit is designed to work with most speakers, but make sure
to buy one that meets these minimum requirements:
•
•
Minimum 8-ohm resistance
Minimum 5-watt power
In your vessel or vehicle, mount the speaker wherever you want to hear
your unit's sounds. (Follow the speaker's installation instructions).
Next, connect the speaker to your unit. The external audio wires are
the labeled red and black wires in the power/data cable. The speaker's
input cable should have two exposed wires: a positive and a negative
(ground). Connect the speaker's positive wire to the unit's red speaker
wire, and the speaker's negative (ground) wire to the unit's black
speaker wire.
The unit should automatically begin to play any active sounds through
the attached speaker.
Face Cover
Your unit comes with a white protective cover that snaps on and off the
front of the unit. When the unit is in storage, the cover protects the
screen from damage that can result from long-term exposure to the
sun's ultraviolet rays. 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.
Now that you have your unit installed, move on to Sec. 3, Basic Sonar
Operations. There, we'll present a series of step-by-step tutorials to
teach you the basics of your sonar operation.
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. 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.)

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 the unit is to operate, the following page contains a simplified,
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.

LCX-104C 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 arches. When you see
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 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 ↓ to align the cursor line with the fish arch. The exact depth ap-
pears 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.
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. 4
Fig. 3
These figures show results of different sensitivity levels on the same
location. Fig. 1: Sensitivity at 88 percent, determined by Auto Sensitiv-
ity. Typical of full auto mode. Fig. 2: Sensitivity set at 75 percent. Fig.
3: Sensitivity set at 50 percent. Fig. 4: Sensitivity set at 100 percent.
You can change the sensitivity level whether you are in Auto Sensitiv-
ity mode or Manual Sensitivity mode. The adjustment method works
the same in both modes, but it gives you slightly different results.
48

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 this 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 sensi-
tivity 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 this 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
turtles! To see what's under your boat in maximum detail, we recom-
mend 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 Lowrance 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 ASP feature 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.
To change the ASP level:
1. From the Sonar Page, press MENU|↓ to SONAR FEATURES|ENT.

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.

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.
ColorLine
ColorLine lets you distinguish between strong and weak echoes. It
"paints" a brighter color on targets that are stronger than a preset
value. This allows you to tell the difference between a hard and soft
bottom. For example, a soft, muddy or weedy bottom returns a weaker
signal which is shown with a narrow, colored line (dark blue tinged
with red or a little yellow.) Since fish are among the weakest echoes,
they show up mostly as blue arches. A hard bottom or other relatively
hard target returns a strong signal which causes a wider brightly col-
ored line (reddish yellow to bright yellow.)
If you have two signals of equal size, one with red to yellow color and
the other without, then the target with brighter color (yellow) is the
stronger signal. This helps distinguish weeds from trees on the bottom,
or fish from structure.
ColorLine is adjustable. Experiment with your unit to find the Color-
Line setting that's best for you.
At left, Sonar Page menu with ColorLine command selected.
At right, the ColorLine control bar.
To adjust the ColorLine level:
1. From the Sonar Page, press MENU|↓ to COLORLINE|ENT.

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.

Frequency (Change Transducer Frequency)
(Dual-Frequency Transducers only)
A dual-frequency 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.
65
Download from Www.Somanuals.com. All Manuals Search And Download.
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.

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.
69
Download from Www.Somanuals.com. All Manuals Search And Download.
However, when you are running at high speeds, or just want the fastest
possible screen update, you may want to use the HyperScroll feature.
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.

Set Keel Offset
This unit measures water depth from the face of the transducer. Since
the transducer is installed below the water surface, the distance dis-
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 impor-
tant, you can calibrate the depth indicators so that they show the ac-
tual water 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 en-
tered 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.

ber to 5, then press EXIT. The depth indicators now accurately show
the water depth from surface to bottom.
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.)

Tip:
For quicker sensitivity adjustments, try leaving the Sensitivity
Control Bar on the screen as the chart scrolls. You can see the
changes on the screen as you press the up or down arrows. This is
handy when there's a lot of clutter in the water, and you are
matching the sensitivity to rapidly changing water conditions.

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.
84

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 61)
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 certain 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 11 volts. If it isn't, the wiring to the unit is defective, the
battery terminals or wiring on the terminals are corroded, or the
battery needs charging.
Unit operates only in demo mode:
The transducer or antenna module has not yet been connected or has
been disconnected. To leave demo mode, make sure that either the
transducer or the antenna is securely connected before turning the unit on.
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
transducer 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 both the transducer and power connectors. Make certain both
are securely plugged in to the unit.
Weak bottom echo, digital readings erratic, or no fish signals:
1. Make certain the transducer is pointing straight down. Clean the
face of the transducer. Oil, dirt and fuel can cause a film to form on the
transducer, 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. Do NOT use RTV
silicone rubber adhesive or Marine-Tex epoxy.
2. Electrical noise from the boat's motor can interfere with the sonar.
87

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.
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
happens, 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
reading 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
resistor 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 certain 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
display 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
display 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
appears on the sonar's display as random patterns of dots or lines. In
severe cases, it can completely cover the screen with black dots, or
cause the unit to operate erratically, or not at all.
To eliminate or minimize the effects of electrical noise, first try to
determine 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)].
Sensitivity 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
motor, 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 certain 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 certain everything except the sonar unit is turned off, then start
the engine. Increase the RPM with the gearshift in neutral. If noise
appears 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 certain to use the in-line fuse
supplied 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
transducer owner's manual for the best mounting position.

No matter what Page you are on, a flashing current position indica-
tor/question mark symbol and flashing GPS data displays indicate that
satellite lock has been lost and there is no position confirmed. The Sat-
ellite Status Page shows you the quality and accuracy of the current
satellite lock-on and position calculation.
WARNING:
Do not begin navigating with this unit until the numbers
have stopped flashing!
Satellite Status Page. Left view indicates unit has not locked on
to any satellites and does not have a fix on its position. Right
view shows satellite lock-on with a 3D position 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 light blue. The re-
ceiver hasn't locked onto a satellite if the number is dark blue, 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.
The "Estimated Position Error" (horizontal position error) shown in the
upper left corner of the screen is the expected error from a benchmark
location. In other words, if the EPE shows 50 feet, then the position
shown by the unit is estimated to be within 50 feet of the actual loca-
tion. This also gives you an indicator of the fix quality the unit cur-

rently has. The smaller the position error number, the better (and more
accurate) 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.
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.

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 window 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 red 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
following 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 window 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.)

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 magenta 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 example fig-
ure below, 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 37
available map zoom ranges, from 0.05 miles to 4,000 miles.
Far left, Map Page opening screen. Center, zoomed to 100 miles and
right, zoomed to 15 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, and you can
zoom in to 0.05 miles with massive 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 6 mile zoom range, with a
few Point of Interest icons visible. Center, numerous dots representing
Points of Interest become visible at the 3 mile range, along with minor
streets. Right, at the 0.6 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 contains: 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.

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 147. 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.

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 right 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.
Simply use the arrow keys to position the cursor over the object or
landmark. The distance, measured in a straight line, appears in the
pop-up box. Press EXIT to clear the cursor.

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.
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.
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.

menus, you could have gone looking for another place.)
NOTE:
Search works from mapping and POI data loaded in the LCX-104C.
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.

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 it, 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 repeat 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 se-
lected.
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.

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.)

Navigate to cursor. In this example, the cursor has selected the town of
Oologah, Oklahoma.
3. Press MENU|ENT and the LCX-104C will begin navigating to the cur-
sor location.
The Map Page will display a red line from your current position to the cur-
sor position. The Navigation Page displays a compass rose showing naviga-
tion information to your destination. See the following examples.
The 30-mile zoom figure at left clearly shows the red course line connect-
ing your current position to your destination. The 30-mile zoom, center,
shows both current position and direction to 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
LCX-104C 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 the → to make sure the GO TO command is highlighted at the top of
the screen, then press ENT. The LCX-104C begins showing navigation
information to the item.
To cancel navigation, press MENU|MENU|↓ to CANCEL NAVIGATION|ENT|←
to YES|ENT. The LCX-104C stops showing navigation information.
Creating and Saving a Trail
A trail, or plot trail, is a string of position points plotted by the LCX-
104C 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 magenta line extending from the back of the current position arrow.
The LCX-104C 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 LCX-104C 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, the LCX-
104C creates a trail by placing a dot (trail point) on the screen every
time you change directions. (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
by making it inactive before heading to point C or even back to point A.
When the current trail is set inactive, the LCX-104C automatically cre-
ates and begins recording a new trail.

New trail, named "Trail 15," is created when Trail 14 is made inactive.
Any new travel will be recorded in this trail, which is active and visi-
ble. Trails do not need to be visible in order to be active.
You can save and recall up to 10 different plot trails, which can also be
copied to your MMC for archiving or for transfer to your MapCreate
software.

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.
115
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 LCX-104C.
6. When you reach your destination, be sure to cancel your navigation:
press MENU|MENU|↓ to CANCEL NAVIGATION|ENT. The LCX-104C asks if
you're sure; press ←|ENT.

Transfer Custom Maps and GPS Data Files
Custom Maps:
Custom maps work only from the MMC card or SDC card. When a card
containing a Custom Map File is loaded into the unit, it automatically
loads the map into memory when the unit is turned on.
Instructions for copying Custom Map Files to an MMC are contained in
the instruction manual for your MMC card reader and MapCreate 6
software. For instructions on inserting an MMC into the LCX-104C, see
Sec. 2, Installation/Accessories.
NOTE:
To load a Navionics chart, see Sec. 8 for the entry Navionics Charts.
GPS Data files:
GPS Data Files contain waypoints, routes, trails and event marker
icons. Instructions for copying GPS Data Files between your computer
and an MMC are contained in the instruction manual for your MMC
card reader and MapCreate 6 software.
GPS data automatically recorded in the unit's internal memory must be
saved to the MMC (as a GPS Data File) in order to store it on your per-
sonal computer. GPS Data Files stored on an MMC must be copied from
the card to the LCX-104C's internal memory before the unit can read
them. Here's how:

called later for navigation purposes. These are sometimes referred to as
event marker icons. The LCX-104C 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.)

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
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
125

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 gimbal-mounted LCX-104C.
To load a MapCreate route into the LCX-104C, follow instructions in
MapCreate'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 LCX-104C. (See Sec. 2 for instructions on in-
stalling MMCs. To load the GPS Data File into the LCX-104C 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.
1. From the NAVIGATION PAGE, press MENU|ENT or from the MAP PAGE,

Section 8:
System & GPS Setup Options
Alarms
This unit has several GPS alarms. The factory default setting has all
the alarms 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 0.1 mile, then the alarm will flash a
message when you come within 0.1 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 0.1 mile, then the alarm flashes a message if you drift
0.1 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 0.1 mile as an example, if you're anchored and your
boat moves more than 0.1 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.
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.)
3. To change distance settings, scroll ↓ or ↑ to select the desired cate-
gory, then press → |ENT to activate the distance dialog box. Press ↑ or
↓ to change the first character, then press → to the next character and
repeat until the name is correct.

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 0.05 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.

ports, or com ports for short. The Com Port Menu, which is accessed
from the System Setup Menu, allows you to configure the communica-
tions ports to send or receive data to another electronic device, such as
an autopilot. Com port 1 can be used for either NMEA or DGPS Binary
data transfer. Com port 2 is for NMEA output only.

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.
To change the coordinate system, press ENT while COORDINATE SYSTEM is

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.
140

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.
(Please note that in order for this system to work, the lati-
tude/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.) 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 way-
point. See the waypoint section for information on saving a waypoint.
Save the reference position as a waypoint. Exit from the waypoint
screens.
1. Press MENU|MENU|↓ to GPS SETUP|ENT.
2. Press ↓ to COORDINATE SYSTEM|ENT.
3. Press ↓ to SETUP MAP FIX|ENT.
The following screen appears, and MAP SCALE is highlighted. Press ENT
and enter the map's scale. This is generally at the bottom of the paper
map. It's shown as a ratio, for example 1:24000. Press EXIT and the unit
returns to the Configure Map Fix 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 sec-
ond 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.

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:
1. Press MENU|MENU|↓ to GPS SETUP|ENT|↓ to MAP DATUM|ENT.
2. Scroll ↓ or ↑ to select the desired datum, then press ENT.
3. To return to the last page displayed, press EXIT|EXIT.

Map Orientation
By default, this receiver shows the map with north always at the top of
the screen. This is the way most maps and charts are printed on paper.
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.
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

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.

Update Trail Criteria (Auto, Time, Distance)
The options are automatic, time, or distance. When it's in the default
automatic mode, the unit doesn't update the plot trail while you're
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.
From the Trails Menu, press → to OPTIONS|ENT|↓ to UPDATE CRITERIA.
Press ↑ or ↓ to select criteria type|ENT. If you selected Time, the Up-
date Rate data entry box appears on the menu. If you selected Distance,
the Update Distance data entry box appears on the menu.

onds; the default is 3 seconds. You can update by distance, with a range
from 0.01 mile/nm/km to 9.99 mile/nm/km; the default is 0.10 miles.
