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
waypoint, 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
responsible for operating the vehicle in a safe manner. Vehicle
operators must maintain full surveillance of all pertinent driving,
boating or flying conditions at all times. An accident or collision
resulting in damage to property, personal injury or death could occur if
the operator of a GPS-equipped vehicle fails to pay full attention to
travel conditions and vehicle operation while the vehicle is in motion.

Section 1:
Read Me First!
How this manual can get you out on the road, fast!
Welcome to the exciting world of digital sonar and GPS! We know
you're anxious to begin navigating and finding fish, but we have a favor
to ask. Before you grab the unit and begin installing it, please give us a
moment or two to explain how our manual can help you get the best
performance from your combination fish finder and 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
discover 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 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. Like you, we'd rather
spend more time boating or fishing and less time reading the manual!
So, we designed our book so you don't have to read the whole thing from
front to back to find 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
introduction to the unit's sonar and GPS. It tells you the basics you
need to know so you’ll easily be able to make the unit, not only tell you
where you are, but also where to find fish.
Section 2 will help you install your unit, the transducer and the GPS
antenna module. We'll also show you how to install the MultiMedia
Card (MMC) and give you some information on 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
figured out how to install the unit yourself, and you just can't
wait any longer, turn to the Quick Reference on page 51 and
head for the water with your unit!)
After you've gained some experience with your sonar, you'll want to
check out Section 4, which discusses advanced Sonar Options and
Other Features.
1

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, flipping
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
introduces you to Basic GPS Operations. This section features a onepage GPS Quick Reference on page 107.
Section 6 contains short, easy-to-scan GPS lessons that follow one
another 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
experience), you may want to try out some of the unit's many advanced
navigation features. That brings us to Section 7, Advanced GPS
Operations. This section contains the rest of the unit's GPS command
functions, 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, 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
operations. 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,
like 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, warranties and customer service information.
It's important to us (and our power users), but, if you don't care how
many watts of power the unit has, or how many waypoints it can store,
skip ahead to important information on how sonar works, on page 6.
(Background on GPS begins on page 7).

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
technology 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 display. Here’s a simple explanation of how it
finds the bottom and the fish.
The transmitter emits an electrical impulse, which the transducer
converts into a sound wave and sends into the water. (The sound
frequency can't be heard by humans or fish.) The sound wave strikes an
object (fish, structure, bottom) and bounces back to the transducer,
which converts the sound back into an electrical signal.
The receiver amplifies this return signal, or echo, and sends it to the
display, where an image of the object appears on the scrolling sonar
chart. The sonar's microprocessor calculates the time lapse between the
transmitted signal and echo return to determine the distance to the
object. The whole process repeats itself several times each second.
Your 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 are 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
going. (But if you already have a working understanding of GPS
receivers and the GPS navigation system, skip on ahead to Section 2,
Installation & Accessories on page 9. 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
computer 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 mapmaking 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
differences in Section 6, Basic GPS Operations, on page 95.
NOTE
The LCX-26CHD and LCX-111CHD have Nautic Path charts,
HotSpots Elite charts and all high detail custom maps preloaded
onto a 20 Gigabyte hard drive. Therefore, if you own either the
LCX-26CHD or the LCX-111CHD, you do not need to load any of
those charts/maps into the unit. The unit can also use Navionics
charts, but they must be loaded into the unit via a Navionics card.
4

MMC and SD cards still will be necessary to log sonar chart data
and to store GPS data files.
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 computer.
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
(Secure 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 1 GB in size. (Compare that to a floppy disk's 1.44 MB
capacity!) 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.
The other key GPS use for MMCs is storage of special high-detail,
custom maps, which you can produce on your computer with our
MapCreate software. These MapCreate custom maps contain much
greater detail than the basic background map. These Custom Map
Files (file format *.lcm) can also be shared between other Lowrance
GPS or sonar/GPS units and personal computers. (For example, the
exact same MMC, custom map files and GPS data files can be used
interchangeably between your gimbal-mounted unit 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
containing 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
5

9, 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
8. But, if you want to understand the current state of satellite
navigation, look over this segment describing how GPS and its new
companion WAAS work together to get you where you're going.
The Global Positioning System (GPS) was launched July 17, 1995 by
the United States Department of Defense. It was designed as a 24hour-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
available, 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
government 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
locations in the sky. Each satellite broadcasts a low-power signal that
identifies the satellite and its position above the earth. Three of these
satellites are spares, unused until needed. The rest virtually guarantee
at least four satellites are in view nearly anywhere on Earth at all times.

A minimum of three satellites are required to determine a 2D fix.

The system requires signal reception from three satellites in order to
determine a position. This is called a 2D fix. It takes four satellites to
determine both position and elevation (your height above sea level —
also called altitude). This is called a 3D fix.
Remember, the unit must have a clear view of the satellites in order to
receive their signals. Unlike radio or television signals, GPS works at
6

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
satellites 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
Aviation Administration has special needs for aircraft traffic control
that go beyond basic GPS. The FAA has a plan under way to boost GPS
performance 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
eventually make instrument landings and takeoffs more accurate as it
replaces 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. WAAS,
however, 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
consistently 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. But remember this receiver is
only a tool. Always have another method of navigation available, such
as a map or chart and a compass.
Also remember 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. It’s up to you to safely navigate around obstacles,
no matter how you’re using this product.

The other keys perform a variety of functions. When the text refers to a
key to press, the key is shown in bold. For example, the "Enter/Icons"
key is shown as ENT and the "Menu" key is shown as MENU.
Menu Commands
A menu command or a menu option will appear in small capital letters, in
a bold sans serif type like this: ROUTE PLANNING. These indicate that you are
to select this command or option from a menu or take an action of some
kind with the menu item. Text that you may need to enter or file names
you need to select are show in italic type, such as trail name.
Instructions = Menu Sequences
Most functions you perform with 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.
In clearer terms, step 1 (above) means: "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: "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."

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
drilling 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
sonar/GPS unit.
6. Install the GPS antenna and route the antenna cable to the
sonar/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
transducer does "kick-up," the bracket can easily be pushed back into
place without tools.
9

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
the epoxy is applied and it is set into position, the transducer 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.
NOTE
The following installation types also call for these recommended
tools and required supplies (supplies are not included):
Single-frequency transom installations

Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flathead screwdriver. Supplies: high quality, marine grade above- or belowwaterline sealant/adhesive compound.
Dual-frequency transom installations

Tools: two adjustable wrenches, drill, #20 (0.161") drill bit, flat-head
screwdriver. Supplies: four, 1" long, #12 stainless steel slotted wood
screws, high quality, marine grade above- or below-waterline
sealant/adhesive compound.
Single-frequency trolling motor installations

Tools: two adjustable wrenches, flat-head screwdriver. Supplies: plastic
cable ties.
Shoot-through hull installations

Tools: these will vary depending on your hull's composition. Consult your
boat dealer or manufacturer. Other tools are a wooden craft stick or
similar tool for stirring and applying epoxy, and a paper plate or piece
of cardboard to mix the epoxy on. Supplies: rubbing alcohol, 100 grit
sandpaper, specially formulated epoxy adhesive available from LEI (see
ordering information on the inside back cover). A sandwich hull also
requires polyester resin.
Selecting a Transducer Location
1. The location must be in the water at all times, at all operating speeds.
2. The transducer must be placed in a location that has a smooth flow of
water at all times. If the transducer is not placed in a smooth flow of
water, interference caused by bubbles and turbulence will show on
the sonar's display in the form of random lines or dots whenever the
boat is moving.
10

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 transom location on
aluminum boats is between the ribs closest to the engine.
3. The transducer should be installed with its face pointing straight
down, if possible. For shoot-thru applications: Many popular fishing
boat hulls have a flat keel pad that offers a good mounting surface. On
vee hulls, try to place the transducer where the deadrise is 10° or less.
Deadrise less than 10°

Strakes
Pad
Left, vee pad hull; right, vee hull. A pod style transducer is shown here,
but the principle is the same for Skimmers inside a hull.

4. If the transducer is mounted on the transom, make sure it doesn't
interfere with the trailer or hauling of the boat. Also, don't mount it
closer than approximately one foot from the engine's lower unit. This
will prevent cavitation (bubble) interference with propeller operation.
5. If possible, route the transducer cable away from other wiring on the
boat. Electrical noise from engine wiring, bilge pumps and aerators
can be displayed on the sonar's screen. Use caution when routing the
transducer cable around these wires.
CAUTION: Clamp the
transducer cable to transom
near the transducer. This will
help prevent the transducer
from entering the boat if it is
knocked off at high speed.

How low should you go?
For most situations, you should install your Skimmer transducer so
that its centerline is level with the bottom of the boat hull. This will
usually give you the best combination of smooth water flow and
protection from bangs and bumps.
Transom

Transducer
centerline

Hull bottom
Align transducer centerline with hull bottom.

However, there are times when you may need to adjust the transducer
slightly higher or lower. (The slots in the mounting brackets allow you
to loosen the screws and slide the transducer up or down.) If you
frequently lose bottom signal lock while running at high speed, the
transducer may be coming out of the water as you cross waves or
wakes. Move the transducer a little lower to help prevent this.
If you cruise or fish around lots of structure and cover, your transducer
may be frequently kicking up from object strikes. If you wish, you may
move the transducer a little higher for more protection.
There are two extremes you should avoid. Never let the edge of the
mounting bracket extend below the bottom of the hull. Never let the
bottom – the face – of the transducer rise above the bottom of the hull.
Shoot-thru-hull vs. Transom Mounting
In a shoot-thru-hull installation, the transducer is bonded to the inside
of the hull with epoxy. The sonar "ping" signal actually passes through
the hull and into the water. This differs from a bolt-thru-hull
installation (often called simply "thru-hull"). In that case, a hole is cut in
the hull and a specially designed transducer is mounted through the
hull with a threaded shaft and nut. This puts the transducer in direct
contact with the water.
Typically, shoot-thru-hull installations give excellent high speed
operation and good to excellent depth capability. There is no possibility
of transducer damage from floating objects, as there is with a transommounted transducer. A transducer mounted inside the hull can't be
knocked off when docking or loading on a trailer.
12

The shoot-thru-hull installation, however, 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
on your sonar display. (This is not an issue for flasher-style sonars.)
Lack of angle adjustment can be particularly troublesome on hulls that
sit with the bow high when at rest or at slow trolling speeds.
Third, a transducer CAN NOT shoot through wood and metal hulls.
Those hulls require either a transom mount or a thru-hull installation.
Fourth, if your Skimmer transducer has a built in temp sensor, it will
only show the temperature of the bilge, not the water surface temp.
Follow the testing procedures listed in the shoot-thru-hull installation
section at the end of this lesson to determine if you can satisfactorily
shoot through the hull.
Transom Transducer Assembly And Mounting
The best way to install these transducers is to loosely assemble all of the
parts first, place the transducer's bracket against the transom and see if
you can move the transducer so that it's parallel with the ground.
The following instructions sometimes vary depending on the mounting
bracket that came with your transducer. Single-frequency Skimmers
come with a one-piece stainless steel bracket, while dual-frequency
Skimmers come with a two-piece plastic mounting bracket. Use the set of
instructions that fits your model.
1. Assembling the bracket.
A. One-piece bracket: Press the two small plastic ratchets into the
sides of the metal bracket as shown in the following illustration. Notice
there are letters molded into each ratchet. Place each ratchet into the
bracket with the letter "A" aligned with the dot stamped into the metal
bracket. This position sets the transducer's coarse angle adjustment for a
14° transom. Most outboard and stern-drive transoms have a 14° angle.

Dot

Align plastic ratchets in bracket.

B. Two-piece bracket: Locate the four plastic ratchets in the
transducer's hardware package. Press two ratchets into the sides of the
plastic bracket and two on either side of the transducer as shown in the
following 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 transoms
have a 14° angle.

2. Aligning the transducer on the transom.
A. One-piece bracket: Slide the transducer between the two
ratchets. 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.

Ratchets

Insert bolt and check transducer position on transom.

B. Two-piece bracket: Assemble the transducer and bracket as shown
in the following figure. Temporarily slide the bolt though the transducer
assembly but don't tighten the nut at this time. Hold the assembled
transducer and bracket against the transom. Looking at the transducer
from the side, check to see if it will adjust so that its face is parallel to
the ground. If it does, then the "A" positions are correct for your hull.
If the transducer's face isn't parallel with the ground, remove and
disassemble the transducer and ratchets. Place the ratchets into the
bracket holes with the letter "B" aligned with the bracket alignment
mark. Place them on the transducer aligned with the 12 o'clock
position 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
transducer'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).

5. Attaching transducer to transom.
A. One-piece bracket: Remove the transducer from the bracket and
re-assemble it with the cable passing through the bracket over the
bolt as shown in the following figures.

For single-frequency Skimmer, route cable over bolt and through
bracket. Side view shown (left) and seen from above (right).

Both bracket types: Attach the transducer to the transom. Slide the
transducer up or down until it's aligned properly with the bottom of
the hull as shown in the preceding and following figures. Tighten the
bracket's mounting screws, sealing them with the 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
caution 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
entering 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
located above the waterline. After installation, be sure to seal the
hole with the same marine grade above- or below-waterline
sealant used for the mounting screws.
18

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
transducer bracket down. This puts the transducer deeper into the
water, hopefully, below the turbulence causing the noise. Be careful
not to install the transducer bracket 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.
Position 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
trolling 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
transducer is ready for use.

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

If the arch slopes up – but not back down – then the front of the
transducer 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
remove any oil film. Oil and dirt on the face will reduce the
sensitivity or may even prevent operation.
SHOOT-THRU-HULL PREPARATION
Hulls With Floatation Materials

The transducer installation inside a fiberglass hull must be in an area
that does not have air bubbles in the resin or separated fiberglass
20

layers. The sonar signal must pass through solid fiberglass. A
successful transducer installation can be made on hulls with flotation
materials (such as plywood, balsa wood or foam) between layers of
fiberglass if the material is removed from the chosen area.
Fill with resin

Fill with resin

Inner hull

Flotation material

Epoxy to hull first

Outer hull

Use epoxy to place the transducer in 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
directly to the outer layer of fiberglass. After the epoxy cures for 24
hours, fill the remaining space with polyester resin. When the job is
finished, the hull is watertight and structurally sound. Remember, the
sonar signal must pass through solid fiberglass. Any air bubbles in the
fiberglass or the epoxy will reduce or eliminate the sonar signals.
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.
Testing Determines Best Location
Ideally, the shoot-thru transducer should be installed as close to the
transom as possible, close to the centerline. This will give you the best
performance during high speed maneuvers.

Transducer location

(trolling speed)

Shoot-thru-hull transducer locations for
high speed or trolling speed operation.

To choose the proper location for shoot-thru-hull mounting, follow these
testing procedures: (You may need a helper to complete these steps.)
1. Anchor the boat in about 30 feet of water. Add a little water to the
sump of the boat. Plug the transducer into the sonar unit, turn it on,
then hold the transducer over the side of the boat in the water. Adjust
the sensitivity and range controls until a second bottom echo is seen on
the display. (You'll need to turn off Auto Sensitivity, Auto Depth Range
and ASP. Try a range setting that is two to three times the water
depth. The harder (more rocky) the bottom, the easier it will be to get a
second bottom signal.) Don't touch the controls once they've been set.
True bottom

Second bottom

Manual range setting

Example of a second bottom signal. Unit is in 30 feet of water, with
range set at 80 feet and sensitivity set at 87 percent.

2. Next, take the transducer out of the water and place it in the water in
the sump of the boat, face down. (The transducer face is shown in the
figure on the following page.) Notice how the signal strength
decreases. The second bottom signal will probably disappear and the
bottom signal intensity will likely decrease.
22

3. Now move the transducer around to find the best location with the
strongest possible bottom signal. If you find a spot with an acceptable
bottom signal, mark the location and move on to step 4.
If you can't get an acceptable bottom signal, try turning up the
sensitivity by three or five keystrokes and then move the transducer
around once more. If you find a spot that works, mark it and move on to
step 4.
If you have to turn up sensitivity by more than five keystrokes to get a
good signal, the transducer should be mounted on the outside of the
hull. This is especially true if you have to turn sensitivity all the way
up to get a decent bottom signal.
4. Most people can get good results by following steps 1 through 3, so this
step is optional. If you want to make an extra effort to be absolutely sure
that your selected location will work under all conditions, make a test
run with the boat on plane and observe the bottom signal. You'll need to
figure some way to prop the transducer into position while you make
your test run. (A brick or two might be sufficient to hold it in place.)
5. When you're satisfied with a location, mark it and proceed with
the installation.
Shoot-thru-hull Installation
If you are installing the transducer on a hull with floatation material
sandwiched within the hull, refer to the text "Hulls With Flotation
Materials" beginning on page 20.
1. Make sure the area is clean, dry and free of oil or grease, then sand
both the inside surface of the hull and the face of the transducer with
100 grit sandpaper. The sanded hull area should be about 1-1/2 times
the diameter of the transducer. The surface of the hull must be flat
so the entire transducer face is in contact with the hull prior to
bonding. After sanding, clean the hull and transducer with rubbing
alcohol to remove any sanding debris.

WARNING:
Use only the epoxy available from LEI. It has been
formulated to work with these installation procedures.
Other epoxy types may be too thin or may not cure to the
right consistency for optimum transducer performance.
2. The epoxy consists of the epoxy itself and a hardener. Remove the
two compounds from the package and place them on the paper plate.
Thoroughly stir the two compounds together until the mixture has a
uniform color and consistency. Do not mix too fast or bubbles will
form in the epoxy. After mixing, you have 20 minutes to complete the
installation before the epoxy becomes unworkable.
Spread a thin layer of epoxy (about 1/16" or 1.5 mm thick) on the face
of the transducer as shown in the previous figure. Make sure there
are no air pockets in the epoxy layer! Then, apply the remaining
epoxy to the sanded area on the hull.
3. Press the transducer into the epoxy, twisting and turning it to force
any air bubbles out from under the transducer face. Stop pressing
when you bottom out on the hull. When you're finished, the face of
the transducer should be parallel with the hull, with a minimum
amount of epoxy between the hull and transducer.
4. Apply a weight, such as a brick, to hold the transducer in place while
the epoxy cures. Be careful not to bump the transducer while the
epoxy is wet. Leave the weight in place for a minimum of three
hours. Allow the epoxy to cure for 24 hours before moving the boat.
5. After the epoxy has cured, route the cable to the sonar unit and it's
ready to use.

Speed/Temperature Sensors
Optional Speed Sensor Installation
If you wish to purchase an optional or additional speed sensor for your
unit, visit our website, www.lowrance.com, or 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 sealant.
First find a location on the boat's transom where the water flow is
smoothest. Don't mount the sensor behind strakes or ribs. These will
disturb the water flow to the speed sensor. Make sure the sensor will
remain in the water when the boat is on plane. Also make sure the
location 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
sensor on the transom. The bottom of the bracket should be flush with
the hull's bottom. Using the sensor as a template, mark the hull for the
screws' pilot holes. Drill four 1/8" holes, one in each end of the slots.
Mount the sensor to the hull using #8 stainless steel wood screws (not
included). Use a high quality, marine grade above- or below-waterline
sealant to seal the screws. Make sure the sensor is flush with the
bottom of the hull and tighten the screws.

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

GPS Antenna/Receiver Module
The LCX-25C, LCX-26CHD, LCX-110C and LCX-111XCHD packages
include the LGC-2000 GPS module. This device contains the unit's
26

external antenna and receiver for GPS and WAAS signals. The
antenna/receiver module comes with a 25-foot Y-adapter extension
cable. This module can be mounted on a flat surface or pole, or an
optional magnet is available for temporary mounting on any ferrous
surface.

LGC-2000 Module, bottom view (left) and top view (right).

You need to select an antenna installation location that has a clear,
unobstructed view of the sky. After the module is installed, connect it to
the unit. The LGC-2000 can communicate with your GPS unit either
directly (using the supplied extension cable) or through a NMEA 2000
network.
NOTE
See the module’s instruction sheet, publication part number 9880147-981, for complete installation instructions.
In an automobile, you may achieve good results by simply placing the
external antenna on the top of the dash, at the base of the windshield. A
piece of the rubber non-skid shelf liner material available in recreational
vehicle supply stores will help hold the antenna in place. This may not
work well if you have a cab-over design pickup truck camper or motor
home. If dashboard reception is poor, simply relocate the antenna module
elsewhere on the vehicle for a clearer view of the sky.
Connecting Directly to the Unit
After the module is installed, attach it to the end of the Y-adapter
extension cable as shown in the following diagram. To connect it to the
unit, insert the extension cable's splitter plug into the Network socket
on the back of the unit and your system is ready to use.

NOTE:
The extension cable’s shorter branch will have a 60-ohm terminator
attached to it. Do not remove this terminator. When you're not
connecting to a NMEA 2000 buss, you must leave the terminator
connected to this socket for your antenna/receiver to function correctly.
Connecting to a NMEA 2000 Network
The LGC-2000 can be connected to a NMEA 2000 buss, providing GPS
information to any Lowrance GPS units attached to the buss. Contact LEI
Extras (look inside back cover for accessory ordering information) for a
NMEA 2000 buss adapter cable if you would like to do this.
There are two ways to connect the antenna to a NMEA 2000 network
port. One method (shown in the following image) is to use the extension
cable's Y-adapter to connect both the antenna and the unit to the same
network port. To do this, simply remove the 60-ohm terminator shown in
the previous image and attach the NMEA 2000 buss adapter cable to the
shorter branch of the extension cable's Y-adapter. Connect the NMEA
2000 buss adapter cable's other end to an available network port.

other to an available port on the NMEA 2000 buss, as shown in the
following image. (You will have to use a similar adapter cable to connect
the GPS unit to the NMEA buss as described later in this section.)

NOTE:
An existing operational NMEA 2000 buss will already have
terminators in place and will already be powered. If you're connecting
to such a network, you won't need the terminators or extension cable
provided. Do not add terminators or power to a functional NMEA
2000 buss!
When the LGC-2000 is connected to the unit (directly or indirectly), it
will begin providing GPS signal information.

Power Connections
Your unit comes with a power/data cable that splits into three ends,
each with several exposed wires (shown in the following figure). The
end with 4 wires (blue, yellow, orange and shield) is a Data cable that
connects to a NMEA 0183 interface. The end with three wires (red,
black and shield) is a power cable that connects to a NMEA 2000 buss.
The thicker three-wire cable (red, black and white) is the Power Supply
for your unit (and optional external speaker connection).

Depending on your configuration, you may not use all of these wires.
The following segments include instructions for installing all the wires
that you will use with this unit.
Caution
All of the wires in the power/data cable have bare ends for
easier installation. The bare ends on any unused wires could
cause an electrical short if left exposed. To prevent this, you
should cover the individual wire ends – either by capping them
with wire nuts or wrapping them with electrical tape. (You
should cut off the bare wire before taping off the ends.)
29

Powering a NMEA 2000 Buss
(NMEA 2000 Power cable)
A NMEA 2000 buss must be connected to a power source to operate. If
you have a pre-existing NMEA 2000 installation, it may already be
connected to another power source. If your NMEA 2000 buss is already
powered, you can ignore the NMEA 2000 Power cable. Never attach
two power sources to a single NMEA 2000 buss.
If you do need to power your NMEA 2000 buss, attach the NMEA 2000
Power cable to your boat's battery just as indicated in the following
segment for connecting your unit's Power Supply cable. The NMEA
2000 Power cable's red wire should be attached (with provided 3-amp
fuse) to the boat battery's positive terminal, and the NMEA 2000 Power
cable's black and shield wires should both be attached to the battery's
negative terminal.
NOTE:
If the NMEA 2000 buss draws power directly from the boat's battery,
the LGC-2000 will remain on (drawing power) all the time. The LGC2000's current draw is very small and shouldn't decrease the boat's
storage battery life, but if this small draw is a concern, you can
install a switch between the NMEA 2000 buss and the battery.
Powering Your Unit
(Power Supply cable – red and black wires)
The unit works from a 12-volt battery system. For the best results,
attach the power cable directly to the battery. You can attach the power
cable to an accessory or power buss, however you may have problems
with electrical interference. Therefore, it's safer to go ahead and attach
the power cable directly to the battery.
CAUTION:
When using the unit in a saltwater environment, we strongly
recommend that you shut off the power supply to the power cable
when the unit is not in use. When the unit is turned off but still
connected to a power supply, electrolysis can occur in the power
cable plug. This may result in corrosion of the plug body along with
the electrical contacts in the cable and the unit's power socket.
In saltwater environments we recommend you connect the power
cable to the auxiliary power switch included in most boat designs.
If that results in electrical interference, or if such a switch is not
available, we recommend connecting direct to the battery and
installing an inline switch. This will let you shut off power to the
30

power cable when the unit is not in use. When you are not using
the unit, you should always shut off power to the power cable,
especially when the power cable is disconnected from the unit.
If possible, keep the power cable away from other boat wiring, especially
the engine's wires. This will provide the best isolation from electrical
noise. If the cable is not long enough, splice #18 gauge wire onto it. The
power cable has two wires, red and black. Red is the positive lead, black
is negative or ground. (There is also a white wire to power an optional
external speaker for some units.) Make sure to attach the in-line fuse
holder to the red lead as close to the power source as possible.
For example, if you have to extend the power cable to the battery or
power buss, attach one end of the fuse holder directly to the battery or
power buss. This will protect both the unit and the power cable in the
event of a short. It uses a 3-amp fuse.

boat's battery. To attach the NMEA 2000 Power cable, connect the
red wire to battery's + and black and shield wires to battery's –.
WARNING:
This product must be independently fused with the
enclosed 3-amp fuse (or equivalent), even if you connect
to a fused accessory or power buss.
If a malfunction happens inside the unit, extensive
damage can occur if the enclosed fuse is not used. As with
31

all electrical devices, this unit could be damaged to a
point that it is unrepairable and could even cause harm
to the user when not properly fused.
CAUTION:
Do not use this product without a 3-amp fuse wired into the power
cable! Failure to use a 3-amp fuse will void your warranty.
This unit has reverse polarity protection. No damage will occur if the
power wires are reversed. However, the unit will not work until the
wires are attached correctly.

NMEA 2000 Cable Connections
NMEA 2000 is a new buss network specifically designed for boats. This is
a very young industry standard and, at the time of printing, few boats
being built now have a NMEA 2000 buss installed. Over the next few
years, however, NMEA 2000 will become much more common. To help
you get the most out of this technology, your Lowrance unit is designed
to work with a NMEA 2000 network as soon as it becomes available.
Connecting to a NMEA 2000 Network
Your unit can be connected to a NMEA 2000 buss, receiving sensor
information from any Lowrance units attached to the buss. Contact LEI
Extras (look inside back cover for accessory ordering information) for a
NMEA 2000 buss adapter cable if you would like to do this. You can
connect both the unit and antenna module through the antenna's
extension cable (as described earlier), or you can connect the unit directly
to a network port. To do so, attach the adapter cable's manual locking
collar connector to the Network port on the back of the sonar unit and
attach the other end to an available port on the NMEA 2000 buss, as
shown in the following image.
To sonar
unit's Network
socket

As soon as the unit is connected to the network, it will begin receiving
shared information. Please note the buss must be powered to operate.
(See instructions in this section for more on powering NMEA 2000
buss.)
NMEA 0183 Wiring
(Data cable)
To exchange NMEA 0183 data, this unit has one NMEA 0183 version
2.0 communication port. Com port one (Com-1) can be used to receive
NMEA format GPS data. The com port can also transmit NMEA format
GPS data to another device.
32

The four wires for the com port are combined with the Power Supply
cable and NMEA 2000 Power cable to form the power/data cable (shown
earlier). Com-1 uses the yellow wire to transmit, the orange wire to
receive and the shield wire for signal ground. Your unit does not use
the blue wire.

Mounting the Unit: Bracket or In-Dash
You can install the unit on top of a dash with the gimbal bracket. It can
also be installed in the dash or mounted on a portable power supply.
34

If you use the supplied bracket, you may be interested in the optional
R-A-M bracket mounting system. This converts the unit's gimbal
bracket to a swivel mount, which can be used on the dash or overhead
mounting positions.

Optional R-A-M mounting system.

Bracket Installation
Mount the unit in any convenient location, provided there is clearance
behind the unit when it's tilted for the best viewing angle. You should
also make sure there is enough room behind the unit to attach the
power, transducer and GPS antenna/receiver module cables. (A
drawing on the next page shows the dimensions of a gimbal-mounted
unit.)
Holes in the bracket's base allow wood screw or through-bolt mounting.
You may need to place a piece of plywood on the back side of thin
fiberglass panels to reinforce the panel and secure the mounting
hardware.

Install the gimbal bracket. Place the bracket so the arms slope toward
the front of your unit.

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 the
antenna connector and 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
marine caulking compound. No matter what type of installation you
prefer, be sure to leave enough slack in the cables to allow tilting or
swiveling 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.
In-Dash Installation
You can mount the unit in the dash with an optional FM-3 In-Dash
Adapter Kit. The kit includes mounting hardware and a template for
cutting the hole.

In-dash mounting template for this unit, showing dimensions.
NOTE: The figure above is not printed to scale.

MMC or SDC Memory Card Installation
Your unit uses MultiMedia Cards to store information, such as sonar
logs, custom maps, waypoints, trails and other data. The unit can also
use Secure Digital Cards (SD card) to store data. The unit can use up to
two cards; a MMC and a SD card can be used at the same time.
Throughout this manual, we will use the term MMC, but just
remember your unit can use an MMC or SD card to store data.
NOTE
The LCX-26CHD and LCX-111CHD have Nautic Path charts,
HotSpots Elite charts and all high detail custom maps preloaded
onto a 20 Gigabyte hard drive. Therefore, if you own either the
LCX-26CHD or the LCX-111CHD, you do not need to load any of
those charts/maps into the unit. The unit can also use Navionics
charts, but they must be loaded into the unit via a Navionics card.
MMC and SD cards still will be necessary to log sonar chart data
and to store GPS data files.
Both of these solid-state flash memory devices are about the size of a
postage stamp. A SD card is slightly thicker than a MMC. MMCs are
38

available in storage capacities of 8 MB, 16 MB, 32 MB and 64 MB. SD
cards are available in capacities of 8 MB, 16 MB, 32 MB, 64 MB, 128
MB, 256 MB and 1 GB.
Additional MMC cards are available from LEI Extras; see ordering
information inside the back cover of this manual. MMCs and SD cards
are also available at many camera and consumer electronics stores.
The MMC drawer is located on the front of the case. To install an
MMC, twist the drawer retainer counter-clockwise and pull.
The drawer will come out of the unit. Place the MMC in the drawer face
down (see following figures.)

Other Accessories
MMC and MapCreate
Other available accessories include MMC cards, MMC card readers and
MapCreate™ 6 custom mapping software for your computer. MMC card
readers are available in USB versions.

MapCreate™ 6 CD-ROM, left; MMC card reader for USB ports, right.

Switch Boxes
Two switch boxes are available for this unit. One transducer switch box
switches two transducers to one sonar unit. The other transducer switch
box switches two sonar units to one transducer.
If these accessories are not available from your dealer, see the
accessory 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
Shallow Alarm while fishing, or put one in your galley so you can hear
the GPS Arrival Alarm.
You can purchase an external speaker and the wire to connect it at
your nearest audio or marine electronics store. You will need to buy
marine-grade 18 gauge stranded wire. Buy enough of one color (we
suggest white) to run from the unit's Power/Data cable to the speaker.
Buy enough of another color (we suggest black) to run from the speaker
to the battery or fuse box.
The unit is designed to work with most speakers, but make sure you
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 as shown in the following figure.

output is the white wire in the unit power supply cable. Connect this
wire to the speaker's positive (+) wire or terminal with white 18 gauge
wire. Connect the speaker's negative (–) ground wire or terminal to the
negative (–) terminal on your battery or fuse box with black 18 gauge
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. 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. In Sec. 3 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 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.)

Notes

Section 3:
Basic Sonar Operation
This section addresses the unit's most basic sonar operations. The
instructions presented in Sec. 3 follow a chronological order. Sec. 4,
Sonar Options & Other Features, will discuss other more advanced
functions and utilities. Material in Sec. 4 is arranged in alphabetical
order.
Before you turn on the unit, it's a good idea to learn about the different

You can customize how the Sonar Page displays its pictures and other data
in many ways. Your unit also includes several special sonar features and
options that can help you better interpret the underwater scene.
We'll discuss all of those features and options in Sec. 4, but to show you
how easy 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-25C, LCX-26CHD, LCX-110C & LCX-111CHD
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
details beginning on page 9.)
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
position 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
portion 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:
Zooming in to enlarge the chart for more detail: press ZIN.
Zooming 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
appears in a box at the right end of the cursor line. To clear the cursor,
press EXIT.
9. If you are anchored or drifting at a very low speed, you are not
moving 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.
51

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
situations when too much clutter appears on the screen. Decreasing the
sensitivity can reduce the clutter and show the strongest fish echoes, if fish
are present. As you change the sensitivity setting, you can see the difference
on the chart as it scrolls.
Fig. 1

Fig. 2

Fig. 3

Fig. 4

These figures show results of different sensitivity levels on the same
location. Fig. 1: Sensitivity at 88 percent. 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
Sensitivity mode or Manual Sensitivity mode. The adjustment method
works the same in both modes, but gives you slightly different results.
52

Adjusting sensitivity in Auto Sensitivity Mode is similar to manually
adjusting 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 sensitivity level, with a bias toward the setting you
selected.
Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a
car without cruise control — you have complete 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 water
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.)

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
OPTIONS|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 fish signal
return when he sees it. However, locating a fish via symbol 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
recommend you turn off Fish I.D. and begin learning to interpret fish
arches.
Fish I.D. is most handy when you're in another part of the boat or
performing 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 downrigger 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
possible 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.

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 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
the 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
setting. 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.

Main Menu and Alarms command (left). Sonar Alarms menu (right).
To adjust and turn on the shallow alarm:

To switch to a different depth setting, open the Sonar Alarms menu and
repeat the instructions in step 3 above.
To adjust and turn on the deep alarm:

1. Press MENU|MENU|↓ to ALARMS|ENT|↓ to SONAR ALARMS|ENT.
2. Press ↓ to DEEP ALARM ENABLED|→ to DEEP ALARM DEPTH|ENT.
3. Press ↑ or ↓ to change the first number, then press → to move the
cursor to the next number and repeat until the depth is correct, then
press ENT.
4. Press ← to DEEP ALARM ENABLED|ENT|EXIT|EXIT|EXIT.
To switch to a different depth setting, open the Sonar Alarms menu and
repeat the instructions in step 3 above.
Zone Alarm
The zone alarm is triggered when any echo passes inside the zone
alarm bar, shown on the right side of the screen.
To adjust and turn on the zone alarm:

Sonar Alarms menu, with Adjust Zone command selected (left); Adjust
Zone Alarm selection box, with Upper Limit selected (right).

3. To set the upper boundary for the Zone Alarm, use ← or→ to select
UPPER, then press ↑ or ↓ to move the top of the bar to the desired depth.
4. To set the lower boundary for the Zone Alarm, use ← or→ to select
LOWER, then press ↑ or ↓ to move the bottom of the bar to the desired
depth.
5. Press EXIT|← to ZONE ALARM ENABLED|ENT|EXIT|EXIT|EXIT. Now, any
echo — fish, bottom, structure — within the zone alarm's depth range
will trigger the zone alarm.
To switch to a different depth setting, open the Sonar Alarms menu and
repeat the instructions in steps 3 and 4 above.
59

Fish Alarm
Use the fish alarm for a distinctive audible alarm when fish or other
suspended objects are detected by the Fish I.D. feature (Fish I.D.
must be turned on for the Fish Alarm to work). A different tone sounds
for each fish symbol size shown on the display.

indicating the alarm is turned off.
To turn on the fish alarm:

Calibrate Speed
The speed sensor can be calibrated to compensate for inaccuracies.
Before you change the setting, first calculate the percentage that the
speed is off. You will enter this percentage in a moment.
For example, if you figure the sensor is reading 10 percent faster than
actual speed, you will enter – 10 in the calibration window. If the
sensor 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
possible. (Unless, of course, you are taking the current speed into
consideration when making your calculation.) After you have a correct
figure, here's how to enter it:
1. Press MENU|MENU|↓ to SONAR SETUP|ENT|↓ to CALIBRATE WATER
SPEED|ENT.
60

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 echoes scroll across the screen is called the chart speed. The
default is maximum. We recommend you leave the setting there for
virtually all fishing conditions.
You, however, might consider experimenting with chart speed when
you are stationary or drifting very slowly. You may sometimes achieve
better images as you slow 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.

Sonar Page menu with Chart Speed command selected (left);.
The Chart Speed Control Bar (right).

If you do experiment with chart speed, remember to reset it to
maximum 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 return a stronger signal. This
allows you to tell the difference between a hard and soft bottom. For
61

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 displayed as a wide, brightly colored 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
ColorLine setting that's best for you.

2. The depth cursor appears. Press ↓ ↑ to move the cursor line.
3. To clear the depth cursor, press EXIT.

Depth Range - Automatic
When turned on for the first time, the bottom signal is automatically
placed in the lower half of the screen. This is called Auto Ranging and
is part of the automatic function. You can change the range to a
different depth, depending upon the bottom depth and the current
range. To do this:
1. From the Sonar Page, press MENU|↓ to DEPTH RANGE|ENT.

shaded numbers can not be selected.
3. When the new range is selected, press EXIT to clear the menu.
64

Depth Range - Manual
You have complete control over the range when the unit is in the
manual mode. There are 16 depth ranges, from 5 to 4,000 feet.
To switch to Manual Depth Range:

1. First, turn off automatic depth range. From the Sonar Page, press
MENU|↓ to AUTO DEPTH RANGE|ENT.
2. Press ↑ to DEPTH RANGE|ENT and the Depth Range Control Scale appears.
3. Press ↓ or ↑ to select a different depth range. A horizontal blue bar
highlights the selected range.
4. When the new range is selected, press EXIT to clear the menu.
NOTE
The sonar's depth capability depends on the transducer
installation, water and bottom conditions, and other factors.

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

FasTrack
This feature automatically converts all echoes to short horizontal lines
on the display's far right side. The rest of the screen continues to
operate normally. FasTrack gives you a rapid update of conditions
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 signals are
long, drawn out lines on a normal chart display. FasTrack converts the
graph to a vertical bar graph that, with practice, makes a useful
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 undesirable signals. 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 recognizes a target as a small fish, a medium fish
symbol 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
extending outward from a group of limbs are the hardest objects 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 also is true.
Does that mean Fish I.D. is broken? No. The feature is simply
interpreting 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. Practice with Fish I.D. mode on and off to become more
familiar with it. The default for Fish I.D. is off.

Frequency (Change Transducer Frequency)
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
frequency is the best choice.
The 200 kHz transducer will give you better detail and definition, but
less depth penetration. The 50 kHz transducer will give you greater
depth penetration, but a little less detail and less definition. (Remember,
all sonar units typically read deeper in fresh water than in salt water.)
There is a common exception to these rules of thumb. Some fishermen
on freshwater lakes (or the ocean) using downriggers like to see them
69

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
automatically provides enough return echoes to refresh the screen and
scroll the chart at maximum chart speed.
However, when you are running at high speeds, or just want the fastest
possible screen update, you may want to use the HyperScroll feature.
When you change the Ping Speed to any setting greater than 50
percent, 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
75

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.

Reset Water Distance
The sonar chart's Digital Data display option includes a window that
shows distance traveled, called Water Distance ("W Distance"). This
information is calculated from an optional water speed sensor, not the
GPS. The Water Distance window can be reset to zero using the Reset
Water Distance command.
Press MENU|MENU|↓ to SONAR SETUP|ENT|↓ to RESET WATER
DISTANCE|ENT. The menus are cleared and water distance is reset to 0.00.

Set Keel Offset
This unit measures water depth from the face of the transducer. Since
the transducer is installed below the water surface, the depth displayed
by the digital depth, chart depth scale, chart cursor or fish symbols is
not exact. If the transducer is 1 foot below the surface, and the screen
shows the water depth as 30 feet, then the actual depth is 31 feet.
On sailboats or other large vessels with deep drafts, the distance
between 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
77

feet. This will entered as a negative 3.5 feet, which makes the depth
indicators perform as if the transducer's lower in the water than it really
is.
1. Press MENU|MENU|↓ to SONAR SETUP|ENT.
2. Use ↓ to scroll down to KEEL OFFSET, then press ENT. 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 water
depth beneath the keel.
NOTE:
If knowing the exact depth of water beneath the keel is less
important, you can calibrate the depth indicators so that they show
the actual water depth from surface to bottom. To do this, first
measure the distance from the face of the transducer to the surface
(the water line on the boat). In this example, we will use 1.5 feet. This
will be entered as a positive 1.5 feet, which makes the depth
indicators perform as if the transducer's higher in the water than it
really is.
1. Press MENU|MENU|↓ to SONAR SETUP|ENT.
2. Use ↓ to scroll down to KEEL OFFSET, then press ENT. The Keel
Offset dialog box appears with a plus (+) sign at the front of the
box.
3. Press → to the first number, then press ↑ to change the number
to 1.
4. Press → to the second number, then press ↑ to change the
number to 5 and press EXIT. The depth indicator now accurately
shows the water depth from surface to bottom.

Sensitivity & Auto Sensitivity
Sensitivity controls the ability of the unit to pick up echoes. 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 solid bottom signal with some surface clutter.
78

Automatic Sensitivity
The default sensitivity mode is automatic. The unit bases the
sensitivity level on water depth and conditions. When the unit is in the
automatic 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.
Situations occur, however, when it becomes necessary to increase or
decrease sensitivity. This typically happens when you wish to see more
detail, so an increase in sensitivity is needed. Or when wave action and
boat wakes create tiny air bubbles that clutter much of the water
column. In that case, a decrease in sensitivity is necessary 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
adjustments, 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
setting 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.)

Sonar Menu with Sensitivity command selected (left).

To adjust sensitivity in manual mode:
1. First, turn off Auto Sensitivity: from the Sonar Page. Press MENU|↓
to AUTO SENSITIVITY|ENT.
2. Press ↑ to SENSITIVITY|ENT and the Sensitivity Control Bar appears.
Press ↓ or ↑ to pick a different sensitivity setting. When it's set at the
desired level, press EXIT.
To turn Auto Sensitivity back on:
From the Sonar Page, press MENU|↓ to AUTO SENSITIVITY|ENT|EXIT.
NOTE:
To return to the original factory setting for Auto Sensitivity, see the
entry in this section on Reset Options. If sensitivity is in manual
mode, the Reset Options command will switch back to Auto and
reset the factory setting at the same time.

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

Sonar Chart Mode
The default color scheme for the sonar chart is white background, but
we offer other variations to suit your viewing preferences. The chart
can be displayed in Grayscale, Reverse Grayscale, Blue Background,

Full Sonar Chart
This is the default mode used when the unit is turned on for the first
time or when it's reset to the factory defaults.
The bottom signal scrolls across the screen from right to left. Depth
scales on the right side of the screen aid in determining the depth of
targets. The line at the top of the screen represents the surface. The
bottom depth and surface temperature (if equipped with a temperature
sensor or a transducer with a temp sensor built in) show at the top left
corner of the screen.
The FasTrack™ display shows just to the right of the scale. This
changes all echoes into short horizontal bars, replicating a flasher
sonar. The zoom bar on the far right shows the area magnified when
the zoom is in use. (See the Zoom section on page 92 for more
information.)

While you're in the Sonar Simulator menu, don't forget to check
Simulate Position if you want to run the sonar and GPS simulators
simultaneously. As you review sonar logs, you can create waypoints
to mark sites you want to return to.
While the simulator is running, you can switch from one chart log
to another by opening the Sonar Simulator menu and using the
instructions in step 2 to select a different chart.
NOTE
If you turn on your unit before attaching a transducer, it may enter
a demo mode. The words "demo mode" flash on the bottom of the
screen and a sonar chart plays much like the simulator. Unlike the
simulator, the demo mode is for demonstration only, and will
automatically stop as soon as you turn on the unit with a
transducer attached. The simulator will continue to function
normally.

Stop Chart
If you are running multiple units on a boat or using this unit in a car,
there are times when you may want to turn off the sonar. This
command turns off the sonar and stops the chart from scrolling. Sonar
restarts 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.

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 in" is a fast and easy method used to enlarge small detail,
fish signals and the bottom with its associated structure. This unit lets
you zoom in quickly and easily by pressing the Zoom In key, ZIN.
Pressing ZIN once doubles the size (2X) of all echoes on the screen.
Pressing it again quadruples the size of the echoes (4X). The zoom bar
on the far right side of the screen shows which echoes will be displayed
on the screen when the ZIN key is pressed.
For example, pressing the ZIN key once will enable a 2X zoom that 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 echoes
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.

Sonar page zoomed 2X (left). The same view zoomed 4X (right).

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
65) and turn on 2X or 4X Zoom. Then press ↑ or ↓ to pan up and down
the water column.

Notes

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 have not yet been connected or have
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.
91

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.
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.
92

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.

98

The Satellite Status Page shows 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!

The Satellite Status Page.

This screen shows a graphical illustration 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 represented by a blue bar. The
receiver hasn't locked onto a satellite if the number is a lighter shade,
therefore 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
location. This also gives you an indicator of the fix quality the unit
currently has. The smaller the position error number, the better (and
more accurate) the fix is.
99

If the position error flashes dashes, then the unit hasn't locked onto the

NOTE:
Remember, when information displays are flashing, satellite lock
has not been achieved and no position 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
traveling. 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
destination 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 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.
Trip 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.)
The Navigation Page has its own menu, which is used for some
advanced functions and for setting various options. (Options and setup
are discussed in Sec. 8.) To access the Navigation Page Menu, from the
Navigation Page, press MENU.
Map Page
The Map Page screens show your course and track from a "bird's-eye"
view. By default, this unit shows the map with north always at the top
of the screen. (This can be changed. See the topic Map Orientation, in
Sec. 8.) If you're navigating to a waypoint, the map also shows your
starting location, present position, course line and destination. You,
however, don't have to navigate to a waypoint 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
following figure appears.
101

The arrow in the center of the screen is your present position. It points
in the direction you're traveling. The map zoom range is the distance
across the screen. This number shows in the lower right corner. In the
example below, the range is 15 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.

The Over Zoomed notice in the top left corner means you have reached
the map’s detail limits for the area. Zooming in closer will reveal no
more detail because a custom map has not been loaded on the MMC.

If you're using only the factory-loaded background map, the maximum
zoom range is 20 miles. You can continue 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.

Map Pages with high-detail MapCreate map. Arterial streets appear at
the 6-mile zoom range with a few Point of Interest icons visible (left).
Numerous Points of Interest dots are visible at 3-mile range, along with
minor streets (center). At 0.6-mile zoom, you can see a interstate
highway with an exit, major and minor streets as well as Point of
Interest icons (right).

102

Background map vs. MapCreate map content
The background map includes: low-detail maps of the whole world,
containing cities, major lakes, major rivers, political boundaries, and
medium-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) and some major city streets. Also included
are Interstate, U.S. and state highways, highway exits and exit services
information, large and medium-sized lakes and streams and more than
60,000 navigation aids with 10,000 wrecks and obstructions in U.S.
coastal and Great Lakes waters.
NOTE
The LCX-26CHD and LCX-111CHD have Nautic Path charts,
HotSpots Elite charts and all high detail custom maps preloaded on
a 20 Gigabyte hard drive. Therefore, if you own either the LCX26CHD or LCX-111CHD, you do not need to load any of those
charts/maps into the unit. The unit can also use Navionics charts,
but they must be loaded via a Navionics card. MMC and SD cards
still will be necessary to log sonar chart data and to store GPS data
files.
MapCreate custom maps include massive amounts of information not
found in the background map. MapCreate contains: 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. Many smaller islands
would not be included in the background map, but are in MapCreate.

Tip:
In some urban areas, businesses are so close to one another that
their POI icons crowd each other on the screen. In the preceding
figure, you can see a jumbled pile of POIs along Highway 34. You
can reduce screen clutter and make streets and other map features
easier to see by turning off the display of undesired POIs. (To see
how, check out the Map Detail Category section, page 150.)
The Map Page has its own menu, which is used for several functions
and for setting various options. To access the Map Page Menu, from the

This allows you to change which map the cursor, keyboard and menus
operate on. A blue title bar denotes the active window.
Resize Window is another handy feature for pages that have two major
windows. You can change the horizontal size of the windows to suit
your viewing preference. Here's how:
1. From any two-window display, press MENU|↓ to RESIZE WINDOW|ENT.
2. Two flashing arrows appear along the centerline dividing the two
windows. Press ← or → to adjust the window widths. Press EXIT to clear
the menu. When you are using the Two Maps page, four flashing
arrows appear, which allow you to not only resize the window from side
to side, but also gives you the option of stacking the windows, one on
top of the other.

The following page contains a 12-step quick reference for basic GPS
operations. If you don't want to carry the manual, you might consider
photocopying this reference page and tucking it into your pocket.

106

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

press MENU|MENU|↓ to CANCEL NAVIGATION|ENT|← to YES|ENT.
12. To turn off the unit, press and hold PWR key for three seconds.
107

Find Your Current Position
Finding your current position is as simple as turning the unit on.
Under an unobstructed sky, the unit automatically searches for
satellites and calculates its position in approximately one minute or
less.
If for some reason satellite acquisition takes longer, you may be inside
a structure, a vehicle or in terrain that is blocking signal reception. To
correct this, be sure you are positioned so the unit's antenna module
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. 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,
eastward or westward by using the arrow keys, which launch the crosshair map cursor. This allows you to look at map places other than your
current position. To clear the cursor, press EXIT, which switches the
map back to the current position or the last known position.

Tip:
Use the cursor to determine the distance from your current position
to any map object. Position the cursor over the object or landmark
with the arrow keys. The distance, measured in a straight line,
appears in the pop-up box. Press EXIT to clear the cursor.

Selecting Any Map Item with the Cursor
1. Use the zoom keys and the arrow keys to move around the map and
find the item you wish to select.
2. Use the arrow keys and center the cursor cross-hair on the desired
object. 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.
109

Category Selection menu (left) and list of the nearest restaurants (right).
4. Select the nearest restaurant highlighted at the top and press ENT.
5. The POI information screen appears. This is how you can use the
unit as a business phone directory! If you wanted to navigate there, you
could press ENT, since the GO TO WAYPOINT command is highlighted. But
we just want to see it on the map, so press ↓ to FIND ON MAP |ENT.

name, street address, phone number, latitude/longitude distance and
compass bearing. The Go To command is selected (left). The figure on
the right has the Find On Map command highlighted.

6. The unit's map appears, with the cross-hair cursor highlighting the
restaurant's POI symbol. A pop-up name box identifies the POI, as well
as its distance and bearing. A data box at the bottom of the screen
continues to display the location's latitude and longitude.

110

7. To clear the search and return to the last page displayed, press EXIT
repeatedly. (Before you completely exited out of the Search menus, you
could have gone looking for another place.)
NOTE:
Search works from mapping and POI data loaded in the unit. If you
have not loaded a MMC for the area you are searching, 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 recalled and
used later for navigational 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. It is also possible to 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
"waypoint 003." The waypoint symbol and number appear on the 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 a 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.
112

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
repeat 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, which will be covered later
in this section. 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, we’ll 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. 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 WAYPOINT
command selected.
4. To begin navigating to the waypoint, press ENT.

Set Man Overboard (MOB) Waypoint
One of boating's most terrifying events is having a friend or family
member fall overboard. 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
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 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
automatically 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.

114

The cursor is redirected toward the Man Overboard position on the
Map Page. The victim is astern of the vessel. The GPS shows which
direction to steer for the rescue.

The man overboard position is also stored in the waypoint list for future
reference. It can be edited the same as any other waypoint.
To cancel navigation to MOB, press MENU|MENU|↓ to CANCEL
NAVIGATION|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'd like to visit.
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
Interest, 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.

115

Navigate to cursor. In this example, the town of Oologah, Oklahoma
has been selected.

3. Press MENU|ENT and the unit will begin navigating to the cursor
location.
The Map Page will display a course line from your current position to the
cursor position. See the following examples.

The 30-mile zoom figure (left) clearly shows the course line connecting
your current position to your destination. The 30-mile zoom (right) shows
current position and direction to destination on screen.

116

Navigate to a Point of Interest
POIs in view on the map can be located easily by using 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
earlier 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 unit begins navigating to the item.
To cancel navigation, press MENU|MENU|↓ to CANCEL NAVIGATION|ENT|←
to YES|ENT. The unit stops showing navigation information.

Creating and Saving a Trail
A trail, or plot trail, is a string of position points plotted by the unit as
you travel. It's a travel history, a record of the path you have taken.
Trails are useful for repeating a journey along the same track. They are
particularly handy when you are trying to retrace your trip and go back
the way you came. The unit is set at the factory to automatically create
and record a trail while it is turned on. The unit will continue recording
the trail until the length reaches the maximum trail point setting.
Default is 2,000, but it can record trails up to 9,999 points long. When
the point limit is reached, the unit begins recording the trail over itself.
By default, the trail flashes once a second, making it easier to see
against the background map. With the default auto setting, the unit
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 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 unit automatically creates
and begins recording a new trail.
To Save a Trail
1. Press MENU|MENU|↓ to MY TRAILS|ENT.

2. Press ↓ to the active Trail Name|ENT.
3. Press → then ↓ to ACTIVE|ENT. This unchecks the Active option.
4. To return to the previous page, press EXIT|EXIT|EXIT|EXIT. As you
left the Edit Trail menu, you will notice a new trail was started with a
new sequential number. In the example below, the new trail is number
15, showing zero points. Note Trail 14 is inactive, but is still visible on
the map.

A new trail, "Trail 15," is created when Trail 14 is made inactive. Any
new travel will be recorded in this trail, which is active and visible.
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 be
copied to your MMC for archiving or for transfer to your MapCreate
software.

118

Tip:
Another quick way to stop recording one trail and begin a new one
is to use the New Trail command: Press MENU|MENU|↓ to MY
TRAILS|ENT|ENT.
Caution:
You also have the option of completely turning off trail
recording, under the Trail Options command. However, if the
Update Active Trail option is left off, it will cancel the automatic
trail creation feature.

Displaying a Saved Trail
The active trail is automatically displayed on the map (the "Visible"
option) with the factory default settings. You can selectively turn the
trail display off and on for any saved or active trail. In the Saved Trails
List, visible trails have a check mark in front of the trail name.
To turn off trail display:
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 VISIBLE|ENT. To return to the previous page, press

3. Press ↓ → to VISIBLE|ENT. To return to the previous page, press
EXIT|EXIT|EXIT|EXIT.

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.) Visual trailing, however, provides no navigation
information during the trip, such as the time to your destination.

119

The other two methods provide a full range of navigation data and work
with both the Map Page and Navigation Page. The only difference
between them is "navigating a trail" follows a trail forward (from start
to end) while "backtracking" follows a trail in reverse.)
When hiking at walking speed with a hand-held GPS, we often use
visual back trailing because it is a bit better at following each little
turn on a footpath. At faster speeds, such as the highway or on the
water, 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 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. A navigation option window will appear
asking if you want to be prompted or directed to intermediate waypoints
along the trail. Use → ← to make your selection, then press ENT.
After making your selection, the unit will begin to show navigation
information along the trail.

directed to intermediate waypoints 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 ENT. Press EXIT to clear
the alarm and proceed.
5. Now, begin moving and let your unit guide you.
6. When you reach your destination, be sure to cancel your navigation:
press MENU|MENU|↓ to CANCEL NAVIGATION|ENT. The unit asks if you're
sure, press ←|ENT.

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 a MMC are contained in
the instruction manual for your MMC card reader and MapCreate 6
software. For instructions on inserting a MMC into the Unit, see Sec. 2,
Installation/Accessories.
123

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 a 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 to store it on your personal

Routes
A route is a series of waypoints, linked together in an ordered sequence
to mark a course of travel. You can visualize a route as a string of
beads. The beads represent waypoints and the string represents the
course of travel connecting waypoint to waypoint.
The course from one waypoint to the next is a leg. Routes are composed
of one or more legs. The legs of all GPS routes are based on straight
lines between waypoints.
A route provides the automatic capability to navigate through several
waypoints without having to reprogram the unit after arriving at each
waypoint. Once programmed into the GPS unit, a route provides the
option of navigating forward through the route waypoints or in reverse
order. You can even begin navigating in the middle of a route!
129

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 unit.
To load a MapCreate route into the unit, follow the instructions in
MapCreate's manual for creating and saving a route as part of a GPS
Data File (file format *.usr). Copy the GPS Data File to an MMC and
insert the MMC in the unit. (See Sec. 2 for instructions on installing
MMCs. To load the GPS Data File into the Unit memory, see the entry
on Transfer Custom Maps & GPS Data Files in Sec. 6, Basic GPS
Operations.
Routes Created in the Unit

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.
An arrival alarm also can be set 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. Choose GPS ALARMS|ENT.
2. Scroll ↓ or ↑ to select the desired category, then press ENT to check or
uncheck the Enabled box. This turns the alarm on (checked) or off
(unchecked.)
3. To change distance settings, scroll ↓ or ↑ to select the desired
category, 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.
139

4. When your adjustments are finished, return to the last page
displayed by repeatedly pressing EXIT.
IMPORTANT ALARM NOTES:
Anchor Alarm - The anchor alarm may be triggered even when
you're sitting still. This typically happens when using small (less
than 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 data it acquired
the last time it was turned on. This probably was at the factory. Since
it's almost certain that you're not at our factory, it's probably 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 100 miles from the last location it was used.

To get to Coordinate System Selection:
1. Press MENU|MENU|↓ to GPS SETUP|ENT.
2. Press ↓ to COORDINATE SYSTEM|ENT.
This unit can show a position in degrees (36.14952°); degrees, minutes
and thousandths of a minute (36° 28.700'); or degrees, minutes, seconds
and tenths of a second (36° 28' 40.9"). It can also show position in: UTM
(Universal Transverse Mercator) projection; MGRS (Standard); MGRS
(Standard + 10); Map Fix; Loran TD; British, Irish, Finnish, German,
New Zealand, Swedish, Swiss, Taiwan, Greek and Military grids.
UTM's are marked on USGS topographic charts. This system divides
the Earth into 60 zones, each 6 degrees wide in longitude.
British, Irish, Finnish, German, New Zealand, Swedish, Swiss, Taiwan,
and Greek grid systems are each the national coordinate system used
only in their respective countries. In order to use these grid systems,
you must be in the respective country. This unit will pick the matching
datum for you when you select the grid. See the entry on Map Datum
Selection for more information.
The military grid reference system (MGRS) uses two grid lettering
schemes, which are referred to as standard and standard + 10 MGRS
142

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
positions are shown on all screens. This includes waypoints.
To change the coordinate system, press ENT while COORDINATE SYSTEM is
highlighted. Press the ↑ or ↓ keys to highlight the desired format. Press
ENT. Press EXIT to close the menu.
To setup Loran TD:
NOTE
If the Loran TD conversion is chosen, you must enter the local
Loran chain identification for the master and slaves. Do this by
selecting "Setup Loran TD" at the bottom of the "Coordinate
System" menu and select the ID. Press EXIT to close this menu.

Configure Loran TD menu.

Map Fix
Map Fix is used with charts or maps. This system asks for a reference
position in latitude/longitude, which you take from a marked location
on the map. It then shows the present position as distance on the map
from that reference point.
For example, if it shows a distance of UP 4.00" and LEFT 0.50", you
then measure up four inches and to the left a half-inch from the
reference 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.
143

(Please note that in order for this system to work, the
latitude/longitude lines must be parallel with the edge of the map.
USGS maps are parallel, others may not be. Also, this works better
with smaller scale maps.) The reference position can be anywhere on
the map, but the closer it is to your location, the smaller the numbers
you'll have to manipulate.
Once you've decided on a reference position, you can save it as a
waypoint. See the waypoint section for information on saving a
waypoint. Save the reference position as a waypoint. Exit from the
waypoint screens.
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.

Configure a map fix so the unit can find your position on a printed
chart or topographical map.

Press ↓ to SELECT ORIGIN |ENT. Press → |ENT, then ↓ or ↑ |ENT to choose
a saved waypoint. Select the waypoint you saved the reference point
under and press ENT. The unit displays a waypoint information screen
with the command SET AS ORIGIN selected; press ENT and the unit
returns to the Configure Map Fix menu. Finally, press EXIT to close this
menu. Now press ↑ to COORDINATE SYSTEM|ENT, select MAP FIX from the

1. From the Map Page, go to the simulator menu. Pick a STARTING
POSITION at or near the beginning of your trail/route. Enter an
approximate TRACK (shown in compass degrees) that will point you
toward the start of the trail/route.
2. Set SPEED to zero. Select STEER WITH ARROWS command and press ENT,
which turns on the simulator and returns you to the Map Page.
3. Begin navigating along the trail/route. (If you are close enough to the
first waypoint, the arrival alarm will usually go off as soon as
navigation begins. Press EXIT to clear the alarm.) When navigation
starts, press ↑ to increase speed to the desired setting.
4. Press EXIT to turn off the steering and speed boxes. The unit will now
automatically "steer" along the trail or route. When you arrive at your
"destination," cancel navigation as you normally do.

Tip:
You can pick any spot on the map to begin your simulation session
by using the Initialize GPS command. This makes your unit think
it's located at the position you select.

Hide GPS Features
If there is no GPS antenna/receiver module attached to this unit, the
GPS menus and features can be hidden from view with this command.
The default setting is off, allowing you to rotate between the Sonar
Page and the GPS pages and features. To hide GPS features:
Press MENU|MENU|↓ to SYSTEM SETUP|ENT|↓ to HIDE GPS FEATURES|ENT.
The GPS menus and pages are now hidden.

Initialize GPS
This command makes the unit operate as if it is sitting someplace other
than its actual location. So, you and your unit could be located in
Kansas City, but practice navigating in the ocean off Islamorada,
Florida.
1. With the GPS simulator off, press MENU|MENU|↓ to GPS
SETUP|ENT|ENT.
2. A message appears, telling you to move the cursor near the desired
location and press ENT. When the message automatically clears, follow
the message instructions. Turn on the GPS Simulator.
3. In a moment, your present position marker arrow appears on the
map in the location you selected with the cursor. The unit will consider
that spot as its last known position until changed by either a live
satellite lock-on or a new simulator location.

Map Auto Zoom
This receiver has an auto zoom feature that eliminates much of the
button-pushing characteristic of other brands of GPS receivers. It
works in conjunction with the navigation features.
First, start navigation to a waypoint. (See the waypoint section for
more information on navigating to a waypoint.) Then, with the auto
zoom mode on, the unit zooms out until the entire course shows, from
the present position to the destination waypoint. As you travel toward
the destination, the unit automatically begins zooming in — one zoom
range at a time — always keeping the destination on the screen.
To turn on this feature, from the MAP PAGE, press MENU|↓ to AUTO
ZOOM|ENT|EXIT. Repeat these steps to turn it off.

Map Data
This menu lets you turn the map off, if desired (which turns the map
screen into a GPS plotter); turn on or off the pop-up map info boxes;
draw the map boundaries or boxes around the areas of high detail or fill
water areas with white. You can also turn on or off Map Overlays,
which display latitude and longitude grid lines or range. This menu lets
you select between Standard, Nautic Path, Hotspots Elite and
Navionics Maps. If you own either the LCX-26CHD or LCX-111CHD
the Nautic Path and Hotspots Elite maps already are loaded into your
unit's 20GB hard drive. Navionic charts still must be loaded via a MMC

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

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."
149

Maps that are created 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
datum, which covers the entire world. Other datums may also cover the
entire world, or just a small portion of it. By default, your unit uses the
WGS-84 datum. It, however, can show your position using one of 191
different datums. To change the datum:
1. Press MENU|MENU|↓ to GPS SETUP|ENT|↓ to DATUM SELECTION|ENT.
2. Scroll ↓ or ↑ to select the desired datum, then press ENT.
3. To return to the last page displayed, press EXIT|EXIT.

A list of the datums used by this unit is in the back of this manual.

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 is shown in north up (left) and track up (right).

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. If, however, 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, a "N" is displayed on the map screen
to help you see which direction is north.
To change map orientation: from the Map Page, press MENU|↓ to MAP
ORIENTATION|ENT. Use ↑ or ↓ to select the desired mode, then press ENT.
Press EXIT|EXIT to return to the page display.

Tick Marks setup menu (left) with Thresholds Setup menu (right).

162

Tick Marks setup gives you the option of modifying the gauges
minimum and maximum angles, values and ticks.
Minimum and Maximum Angles gives you control over the numerical
layout of the gauge. You can spread the numbers out around the gauge
or bunch them together in a smaller area.
Minimum and Maximum Values allows you to decide where the gauge's
numbers will begin and where they will top out. For example: you may
decide to start the gauge at 0, 5 or 10 and top it out at 85, 90 or 100.
Minimum or Maximum Tick controls how many tick marks will be
displayed on the gauge. If you set the minimum tick to 1 and the max
tick to 10, there will be 10 tick marks between 0 and 10, 10 and 20 and
so on. In the case of a speedometer, that's one tick for one mile per
hour. If you change the minimum tick to 2 and leave the maximum tick
at 10, you'll have one tick for every two miles per hour. That's five ticks
between 0 and 10, 10 and 20 and so on.
Thresholds setup can be used as a visual aid to mark portions of the
gauge. It is divided into Upper and Lower Thresholds, each containing
major (warning) and minor (caution) threshold settings. Two sets of
numbers must be entered for each threshold. Minor thresholds ranges
are colored yellow. Major threshold ranges are red.

Gauge Text Setup (left). When Restore Defaults is selected (right) the
unit asks if you're sure you want to replace the current settings with
the default settings.

Text setup allows you to individually label gauges. There are two
windows in Text Setup: Gauge Text and Units Text. Units Text is
positioned at the bottom of the gauge. Gauge Text is located above the
Units Text.
Restore Defaults restores the factory default settings. If you run into
trouble modifying any of the gauge settings, Default is there to bail you
out.

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

envelope and tape it to the unit.

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.

box underneath your return address.

shipping courier. Lowrance does not assume responsibility for goods
