Warnings and Cautions

Caution:

Use this radar at your own risk. This radar was designed for

use as a navigation aid. It should not be used for purposes that

require precise measurements of direction, distance, topography

or location. Always compare the navigation information received

from your radar with data from other navigation aids and

sources. When a conflict arises between the navigation data from

your radar and data from other navigation aids, make sure you

resolve the conflict before proceeding with navigation. A CARE-

FUL NAVIGATOR NEVER RELIES ON ONLY ONE

METHOD TO OBTAIN NAVIGATION INFORMATION.

Caution:

International Regulations for Preventing Collisions at Sea man-

date that when radar is on a vessel, the radar must be used at

all times, regardless of weather conditions or visibility. Numer-

ous court decisions have not only ruled the radar must be used,

but that the radar operator must be knowledgeable in all opera-

tional aspects of radar performance or otherwise face a greater

risk of liability if an accident occurs.

Caution:

If you purchased an open array radar antenna, make sure it is

installed in an area free of hardware obstructions and free of po-

tential obstructions like sails, lines or other vessel components

that could intermittently intrude or be caught up in the array

antenna's rotation path.

WARNING: High Voltage Hazard

Dangerously high voltages are present within the radar

scanner unit. The unit contains no user-serviceable

parts. The cover should be removed only by a qualified

radar service technician. Technicians must exercise ex-

treme care when working inside the unit. ALWAYS re-

move power before removing the cover. Some capacitors

may take several minutes to discharge, even after

switching off the radar. Before touching the magnetron

or any high voltage components, ground them with a

clip lead. There are no internal connections or adjust-

ments necessary for installation or operation.

WARNING: Microwave Radiation Hazard

The microwave energy radiated by a radar antenna is

harmful to humans, especially to the eyes. NEVER look

directly into an open waveguide or into the path of ra-

diation from an enclosed antenna. Radar and other ra-

dio frequency radiation can upset cardiac pacemakers.

If someone with a cardiac pacemaker suspects abnormal

operation, immediately turn off the radar equipment

and move the person away from the antenna. Turn off

the radar whenever it is necessary to work on the an-

tenna unit or other equipment in the beam of the radar.

WARNING: Turn Off Radar When Docked

The radar beam can be harmful to humans in close prox-

imity (within 20 yards, or 18.3 meters). When docked, be

considerate of other boats and pedestrians nearby and

remember to turn off your radar. If your boat is in a cov-

ered marina and the radar is on, a metal roof can act as

a reflector, bouncing microwave energy back at your

boat and passengers.

Section 1: Introduction

Thank you for buying a Lowrance Radar with the RIM 100 radar inter-

face module. Your radar consists of three main components: the radar

scanner unit (antenna), your display unit (sold separately) and the RIM

100 radar interface module which connects the scanner and display units.

WARNING:

Radar radiation can be harmful to you and bystanders.

Radar misuse or misunderstanding radar operation

could lead to a collision, which could result in property

damage, personal injury or death.

You must be familiar with the procedures and all warn-

ings and cautions described in the installation and op-

eration manuals in order to operate your radar safely

and effectively.

We know you’re eager to begin using your radar, but first, we want you to

take note of the three instruction manuals you need to read to get started.

First is the Read Me! Insert for Radar Display Unit Software Update

(part number 988-0161-022). It tells you how use the memory card in

your package to update your display unit software to make it radar-

ready. (For your convenience, this information is also repeated below.)

Second is the Radar and RIM 100 Installation Manual (part number

988-0161-001). It tells you how to install your radar's hardware.

Third is this Radar Operation Manual (part number 988-0161-011).

After installing the radar scanner unit, the RIM 100 and the new dis-

play software, you need to read this manual to learn how your display

unit and radar antenna work together.

To get the highest level of performance from your radar, it is a good

idea to keep this manual and your display unit's sonar or GPS instruc-

tion manual handy for reference.

Models Covered

This manual covers the following radar-compatible display units: LCX-

25c, LCX-26c HD, LCX-110c, LCX-111c HD sonar/GPS combos; and

GlobalMap^6500c, GlobalMap^6600c HD, GlobalMap^7500c, Global-

Map^7600c HD GPS units.

Note for GlobalMap users: Menus and function commands in your

units are identical to those shown in this manual, except your display

will not have sonar page options, sonar alarm options or sonar simula-

tor options.

This manual covers the following radar units: LRA-1000, LRA-1500,

LRA-2000 radomes; and LRA-4000, LRA-5000 open array radars.

Update Display Unit Software

Your display unit must have software version 1.3.0 or later to work

with radar. Depending on when you bought your display, it may require

a software update. To avoid delays in setting up your radar system,

your radar package includes an MMC or SD memory card with a basic

software upgrade.

Lowrance continues to regularly develop display enhancements and

new radar features. We strongly recommend that you periodically

check our web site for the latest free radar software updates.

If you or a friend has Internet access, log-on to www.lowrance.com,

browse to our Software page and look for the Product Updates link. If

you lack Internet access, call your dealer or Lowrance Customer Serv-

ice. Complete contact information is on the last page of this manual.

We've made it easy for you to keep up with our latest updates — just

subscribe to our free e-mail software release notices. Look for the link

at the bottom of our Product Software Upgrades web page.

Installing Software Update

1. With the display unit turned off, install the MMC card that contains

the radar software update.

2. Turn on the unit and the update will install automatically.

3. When the update is finished, the unit will power up normally. After

the updated is complete, remove the update MMC from card slot.

NOTE:

This manual assumes you have a basic understanding of your display

and its sonar and/or GPS operations. For complete instructions on

the keyboard, pages and menu structure, refer to the manual packed

with your display. That manual also explains the typographical con-

ventions and symbols we use to describe unit operations.

What is radar?

The word "radar" is an acronym for "RAdio Detecting And Ranging." In

simple terms, this is how it works:

A radio transmitter sends out a quick microwave pulse. A receiver listens

for that signal's echo when it bounces back from something in its path.

Download from Www.Somanuals.com. All Manuals Search And Download.

When the echo returns, it is processed by a computer to determine rela-

tive distance, position and bearing of the object that reflected the sig-

nal. This information is displayed on the display unit's screen. Other

boats or ships, navigational markers, landmasses and the like are re-

ferred to as targets.

By knowing how long it takes for a signal to return, the distance to a tar-

get can be determined. As the radar antenna scans through a 360 degree

rotation, it can show where the target is relative to your position. By re-

peated scans, you can see which direction another vessel is moving.

The following two pages show the basic components of your radar dis-

play screen, which is commonly referred to as the PPI, an old term from

the early days of radar.

Radar Setup

The Radar Setup menu allows you to setup and adjust radar settings,

like Transmit Off Zone and Antenna Park. Most of the settings in the

Radar Setup menu will only have to be set once, but we recommend you

check the settings periodically for general maintenance.

NOTE:

Before starting radar setup, take your vessel out on open water

with fairly calm seas, like an open bay.

The three setup features we want to modify are Adjust Trigger Delay,

Adjust Main Bang Suppression and Adjust Heading Line.

We will set them up in that order, but before making any adjustments,

make sure the display is set to a range of 1/8 nautical miles and that

Gain, Anti-Sea Clutter (STC), Anti-Rain Clutter (FTC), Main Bang

Suppression and Trigger Delay all have been set to zero percent.

Trigger Delay Preparation

Range

1. To reset range to 1/8 nm, make sure you are on the Radar Only page

and press MENU.

2. Use ↑ ↓ to select RADAR RANGE and press ENT, which will call up the

press ENT.

2. Press →|↓ to ADJUST TRIGGER DELAY and press ENT. That will call up

the Adjust Trigger Delay vertical scrollbar.

3. Press ↓ until Trigger Delay is set to zero percent. Press EXIT.

Adjust Trigger Delay

This feature eliminates the time lag between real radar returns and the

time it takes data to be processed by the radar software, a common is-

sue with all radars.

Caution:

If you have any doubt about your understanding of the Trigger

Delay feature, you should have it set up by a qualified radar

technician.

1. The radar should already be in STANDBY mode, so press PWR for 2

seconds to switch the radar into transmission mode. A confirmation

message will appear, press ← to select YES.

2. Press MENU, then select GAIN and press ENT, which will call up the

Gain vertical control bar. Press ↑ to increase the Gain level to around

15%. One or two red rings with blue borders should be visible on the

screen, depending on the wattage of your radar antenna.

3. Now from the Radar Setup menu, press →|↓ to ADJUST TRIGGER DELAY,

then press ENT. The Adjust Trigger Delay vertical scrollbar will appear.

Download from Www.Somanuals.com. All Manuals Search And Download.

The 2 kW models, the LRA-1000 and LRA-1500, will have only one ring

on the display. The 4 kW radars — LRA-2000, LRA-4000 and LRA-5000

— will have two rings on the display. See the following figures.

Before adjusting the Trigger Delay for 4 kW radars, two rings will be

shown on the screen (left). As Trigger Delay is increased, the larger

ring will start to get smaller. The small ring will disappear (right).

You may have to increase gain in the previous step if the rings are not

visible. Increase gain until you have solid red rings shown on the

screen, like in the preceding example. Increasing Gain too much can

cause distortion of the rings.

4. Press ↑ to increase the level of Trigger Delay, which will decrease the

size of the ring. If you have a 4 kW radar, as the large ring decreases in

size, the smaller ring in the center of the screen will disappear, leaving

only one ring.

Increase Trigger Delay to diminish the size of the red ring (left). To set

Trigger Delay correctly, reduce the ring to as small a size as possible,

while keeping a black circle in the middle (enlarged view, right).

In either case, continue to increase the Trigger Delay level until the

ring is as small as possible, while keeping a black circle in the middle.

Every radar is different, but typically, a setting between 35 and 42 per-

cent will get the job done.

Download from Www.Somanuals.com. All Manuals Search And Download.

If you over apply the Trigger Delay, the black circle will disappear. De-

crease the Trigger Delay level and it will reappear.

3. Press EXIT to return to the main page display.

Adjust Main Bang Suppression

Main Bang Suppression is only for 4kW units — LRA 2000, LRA 4000 and

LRA 5000. This feature filters out electronic noise close to your vessel. It

gives you control of radar sensitivity in the area surrounding your ves-

sel, approximately 180 feet in all directions.

Before making any adjustments to Main Bang Suppression, take your

vessel out on open water with fairly calm seas, like an open bay.

Caution:

If you have any doubt about your understanding of the Main

Bang Suppression feature, you should have it set up by a quali-

fied radar technician.

1. From the Radar Setup menu, press →|↓ to ADJUST MAIN BANG SUP-

PRESSION and press ENT. That will launch the Main Bang Suppression

vertical scrollbar.

2. The small red ring we adjusted during Trigger Delay setup will still

be on the display.

3. Press ↑ slowly — Main Bang Suppression can be sensitive — to in-

crease the Main Bang Suppression level so the red ring becomes as thin

as possible.

4. Press ↓ to slowly decrease the level until you have returned the red

ring back to its thinnest point. Every radar is different, but typically, a

setting between 2 and 8 percent will be satisfactory.

NOTE:

In many cases, depending on the radar unit you have, over applying

Main Bang Suppression can make the ring disappear, start to make

it wider or the ring can get to a point where it is as small as it will

get. At this point, increasing the main bang level will not change

the red ring.

If the red ring does not does not decrease in size when increasing

the suppression level, reduce the level until you see a slight in-

crease in the size of the ring, then leave it at that setting.

Main Bang Suppression begins with the same red ring we resized dur-

ing Trigger Delay setup (left). Slowly increase Main Bang Suppression

to make the ring as thin as possible (enlarged view, right).

5. Press EXIT to clear the scrollbar from the screen. Now reset Gain,

Anti-Sea Clutter and Anti-Rain Clutter back to a desired level.

Adjust Heading Line

The Heading Line command is used to make sure the green heading

line (zero point) on your display is lined up with the bow of your vessel.

(Before heading line adjustment)

(After heading line adjustment)

The bow of the ship is lined up with the tip of the peninsula (left), but the

green heading line is not. Adjusting the heading line will allow you to align

the direction of the heading line with the direction of the bow (right).

1. Line up the bow of your vessel with a point of reference, like a penin-

sula, lighthouse or other stationary target.

2. From the Radar Setup menu, press → to select ADJUST HEADING LINE

and press ENT. That will place an arrow on each side of the green

Heading Line.

Download from Www.Somanuals.com. All Manuals Search And Download.

3. Use ← → to adjust the position of the green heading line, so its line

to the reference point's radar image matches your bow's actual line to

the reference point.

4. Press EXIT to remove the heading line arrows from the display.

Adjust Transmit Off Zone

The Transmit Off Zone is a feature that allows you to select an area in

the radar's 360° transmission path where the radar beam will not be

transmitted.

WARNING:

ALL targets inside the Transmit Off Zone will NOT be

displayed on the screen. This will create a blind spot

within the off zone!

Transmit

Zone

Transmit Off

Zone

Transmit Off Zone is shown in bright red; the remaining area of the

PPI is considered the Transmit Zone. Color is exaggerated here for

clarity; on-screen, the off zone actually appears in a dimmer shade so

as not to distract from target images in the transmit zone. Dialog box

values at upper right are in degrees, relative to the heading line.

Caution:

Preventing the main beam or lobe from transmitting through the

Transmit Off Zone will diminish the amount of radiation

broadcast in that area, but it WILL NOT protect you from radia-

tion transmitted by the side lobes of the radar antenna.

To avoid radiation exposure, be sure to follow the installation

instructions, which require the radar to be installed at least 1

foot above all persons.

1. From the Radar Setup menu, press →|↓ to select ADJUST TRANSMIT OFF

ZONE and press ENT. That will launch the Adjust Transmit Off Zone

dialogs in the upper right-hand corner of the screen.

2, Use ↑ ↓, ← → to set up the Transmit Off Zone in the desired area.

The zone will be colored red on the radar display.

3. Press EXIT when the Transmit Off Zone is set. To remove the zone,

repeat Step 1, then set both dialog boxes back to zero and press EXIT.

Adjust Tune

Tuning should require no adjustment during the life of the unit. We

strongly recommend you do NOT adjust Tune settings yourself.

This feature is intended for use only by trained technicians. If for some

reason you need to use this function, consult your dealer or customer

service about the software updates necessary for tuning.

Section 5: Radar Interpretation

Interpreting images on your radar screen involves as much art as it

does science. If you want to be confident with your radar at night, you

need to practice in daylight. To be ready for fog or a blinding rain

squall, you must practice in fair weather.

Making you an expert radar reader is beyond the scope of this opera-

tion manual. We strongly suggest you seek additional sources of infor-

mation. For a start, the following pages will show you a few basic radar

returns and how to interpret them. See the end of this section for other

information sources that go into much greater detail.

Anti-Rain Clutter (FTC or Fast Time Constant)

The following five figures show how boosting the FTC level can cut

through display clutter caused by rain or snow. Note how these areas of

intense rainfall gradually grow fainter as FTC increases.

amount needed, then check back periodically to see if

the FTC level may be decreased or turned off.

This sequence illustrates a boat entering a channel. The green line is

the track the vessel will take. The magenta line from the stern is a GPS

trail. Study these radar returns with their corresponding maps and

you'll get a feel for how radar displays a shoreline. This channel is sur-

rounded by steeply sloping, rocky hills. Radar signals are strictly line-

of-sight, so this causes land further inland to show no return.

Numbered features on the radar correspond to the same position num-

ber on the map.

other name for a target image detected on the radar display.

Echo trail: a history (trail) of the echoes for a particular radar target.

Gain: used to adjust the sensitivity of the receiver to increase or de-

crease the intensity of images on the display.

Ghost Echo: an undesirable image created when returns are reflected

off other structures.

Guard Zone: an area selected by the radar user, that when activated,

will sound an alarm if any echo passes into the zone.

Shipping Information

If it becomes necessary to send a product for repair or replacement, you

must first receive a return authorization number from Customer

Service. Products shipped without a return authorization will not be

accepted. When shipping, we recommend you do the following:

1. Please do not ship the knobs or mounting bracket with your unit.

2. If you are sending a check for repair, please place your check in an

envelope and tape it to the unit.

3. For proper testing, include a brief note with the product describing

the problem. Be sure to include your name, return shipping address

and a daytime telephone number. An e-mail address is optional but

useful.

4. Pack the unit in a suitable size box with packing material to prevent

any damage during shipping.

5. Write the Return Authorization (RA) number on the outside of the

box underneath your return address.

6. For your security, you may want to insure the package through your

shipping courier. Lowrance does not assume responsibility for goods

lost or damaged in transit.
