INST ALLATION
Bracket
Install the unit in any convenient location, provided there is clearance
behind it when it is tilted for the best viewing angle. Holes in the bracket
base allow wood screw or through-bolt mounting. Make cer tain there is
enough room behind the unit to attach the power and other cables.
9.6”
7.3”
3.7”
2.3”
Once the best location is determined, use the bracket as a template and
mark the mounting holes and the hole for the cables. Drill a 1.0" hole for
the cables. Screw the bracket to the mounting surface.
IMPORTANT!
In order to pass all connectors through the 1" hole in the bracket and
dash, first pass the transducer connector up through the hole, then any
accessory cables. Ne xt, pass the power cab le down through the hole. Fill
the hole with a marine sealant. You can now wire the power cable.
2
Power Connections
This unit operates from a 12-volt battery system. For the best results,
connect the power cable to the in-line fuse holder and attach it directly to
the battery. The power cable can be attached to an accessory or power
buss, however there could be problems with electrical interference using
this method. Therefore, it’s better from a noise standpoint to attach the
power cable and fuse holder directly to a battery. If the cable is not long
enough, splice 16-gauge wire onto it.
The power connector has two cables attached to it. One cable has the
power and ground wires, the other is f or the NMEA/DGPS interf ace . See
below for NMEA/DGPS wiring instructions. The pow er cable has two wires
- red and black. The black wire connects to the battery’s negative terminal. The red wire is the positive wire . Connect it to the fuse holder supplied
with the unit. Connect the other end of the fuse holder to the positive side
of the battery. Make certain to attach the fuse holder directly to the battery. This will protect the both cable and the unit in case there is a shor t
circuit. Use a 6-amp fuse.

IMPORTANT!
Do not use this product without a 6-amp fuse connected to the power
cable! F ailure to use a fuse will void y our w arr anty.

To prevent electrical interference , route the pow er, transducer, and GPS
cables away from other wiring, especially the engine’s wiring harness.
VHF radio antenna cables radiate noise when transmitting, so be certain
to keep the unit’ s wires a w a y from it, also.
NMEA/DGPS
NMEA is a standard communications format for marine electronic equipment. For example, an autopilot can connect to the NMEA interface on
the LCX-16CI and receive positioning information.
DGPS is an acronym for Diff erential Global Positioning System. The most
popular DGPS system relies on a grid of ground-based transmitters that
send correction signals to DGPS receivers. These in turn, connect to the
GPS receiver (such as the LCX-16CI with the LGC-12S GPS module).
This gives more accurate positions than is otherwise possible .
NMEA/DGPS Wiring
The LCX-16CI has two NMEA 0183 version 2.0 ports. Com port one can
be used for either NMEA or DGPS , Com port two is for NMEA output only .
Comunications port one uses the yellow wire wire for transmit, the orange
wire for receive. Comunications port two uses the blue wire for transmit.
Both ports use the shield wire for signal ground.
See the diagrams below f or general wiring connections. Read y our other
product’s owner’s manual for more wiring information.

Accessory Connections
The rear of this unit has three connectors: Power/Data, GPS, and Transducer. The power cable connects to the Po wer/Data connector , the cable
from the GPS module goes to the GPS connector, and the transducer
plugs into the Transducer connector.

Speed/T emperature Connections
This unit can use a speed sensor in addition to up to three temperature
sensors.
All transom-mount “Skimmer” transducers have a temperature sensor b uilt
into them. To add another temperature sensor besides the one in the
transducer requires a MY-4X “Y” adapter cab le and a TS-2X temperature
sensor. The transducer plugs into one end of the MY-4X, the TS-2X temperature sensor plugs into another, and the last end plugs into the SONAR port. The TS-2X temperature sensor has an extra connector for a
TS-3X temperature sensor. This lets you have three temperature sensors, if desired.
Note: Do not combine the temperature sensors in any order other than
shown on the next page. F or example, do not use tw o TS-3X temper ature
sensors in place of one TS-2X and one TS-3X sensors. Each sensor is
programmed to work only on the channel it’s designed f or.

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) show at the top left corner of
the screen. The FasTrak™ 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 that’ s z oomed when
the zoom is in use. (See the Zoom section for more information.) The
frequency of the transducer in use shows at the bottom of the screen.

Split Zoom Sonar Chart
A split chart shows the underwater world from the surface to the
bottom on the right side of the
screen. The left side shows an
enlarged version of the right side.
The zoom range shows at the
bottom left corner of the screen.
In this example, the zoom range
is 2X, or two times the right side’s
view .
Split Frequency Sonar Chart
This chart shows sonar data from
the 50 kHz transducer element (if
equipped) on the left side of the
screen, and data from the 200
kHz transducer element on the
right. All features are the same
as the Full Sonar Chart.
Digital/Chart
This mode shows the chart on the
right side of the screen. The left
side has seven large digital bo xes
containing the W ater Depth at the
top of the screen, (with the shallow and deep alarm settings immediately beneath the depth)
Water Speed (from an optional
speed sensor), Water Distance
(distance travelled or log) also requires a speed sensor. Surface
Water Temperature, Temperature #2, Temperature #3, and input voltage .
(Note: Temper ature #2 and #3 require additional temperature sensors .)

key to. Press the EXIT key when you’re finished. To reassign the menu
key, repeat the above steps.
11
SONAR OPTIONS
Sensitivity
The sensitivity controls the ability of the unit to pick up echoes. A low
sensitivity level excludes much of the bottom information, fish signals,
and other target information. High sensitivity levels let y ou see this detail,
but it can also clutter the screen with many undesired signals. Typically,
the best sensitivity level shows a good solid bottom signal with Grayline
and some surface clutter .
The sensitivity is adjusted to keep a solid bottom signal display ed, plus a
little more when the unit is in the automatic mode. This gives it the capability to show fish and other detail.
However, situations occur where it becomes necessary to increase or
decrease the sensitivity. This typically happens when you wish to see
more detail, so an increase in sensitivity is indicated. The procedure to
adjust it is the same whether the unit is in the automatic or manual mode.
T o adjust the sensitivity, press the
MENU key , then select “Sensitivity”. The screen at right appears.
The sensitivity control has a vertical adjustment bar. The number
at the bottom of the bar shows
the percentage of sensitivity in
use.
To increase the sensitivity level,
press the up arrow key. As you
press the key, the control knob
will move upward and the percentage will increase in v alue . You can also
see the difference on the chart record as it scrolls. When the sensitivity is
at the desired level, release the k ey.
To decrease the sensitivity level, press the down arrow key. The control
knob will move downward and the percentage will decrease. When the
sensitivity is at the desired level, release the k ey. When you reach either
the maximum or minimum limit, a tone sounds.
To erase the menu, press the EXIT key.
Automatic Sensitivity
The unit can adjust the sensitivity for you. It bases the sensitivity level on
water depth and conditions. To tur n this on, press the MENU key, then
12
select “Auto Sensitivity” and press the ENT key. To turn it off, repeat the
above steps. Press the EXIT key to erase the menu.
COLORLINE
Colorline lets you distinguish between strong and weak echoes. It “paints”
gray on targets that are stronger than a preset value. This allows you to
tell the difference between a hard and soft bottom. For example, a soft,
muddy or weedy bottom returns a weaker signal which is shown with a
narrow, lighter colored colorline. A hard bottom returns a strong signal
which causes a wide gray line .
If you have two signals of equal
size, one with color and the other
without, then the target with color
WEAKER SIGNAL
STRONG SIGNAL
is the stronger signal. This helps
distinguish weeds from trees on
the bottom, or fish from structure.
Colorline is adjustable. Since
COLORLINE
Colorline shows the difference
between strong and weak signals, adjusting the sensitivity may
require a different Colorline level, also. The level chosen by the unit at
power on is usually adequate for most conditions. Experiment with your
unit to find the Colorline setting that’s best for y ou.
T o adjust the Colorline le vel, press the MENU key, then select “Colorline”.
The screen above appears . Use the up or down arrow keys to adjust the
color lev el. You can see the change on the chart record as you press the
keys. After you’ve finished, press the EXIT key to er ase the menu.
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. However, depending
upon the bottom depth and the
current range, you can change
the range to a different depth. To
do this, press the MENU key, then
select “Depth Range”. The screen
at right appears. Press the up or do wn arro w k e ys to select a different
13
range that’ s highlighted. The range numbers that are gray cannot be selected. When you’re finished, press the EXIT key to er ase the menu.
RANGE - Manual
You have complete control ov er the range when the unit is in the manual
mode.
To change the range, first turn the automatic depth range off by pressing
the MENU key, then selecting “Auto Depth Range”, then press the ENT
key to turn it off. Next, select “Depth Range”. Press the up or do wn arrow
keys to select a diff erent range. The availab le ranges are 0-10, 20, 30, 40,
60, 100, 150, 200, 300, 500, 800, 1000, 1500, 2000, and 3000 feet. After
selecting the range, press the EXIT key to erase the range menu.
NOTE: The sonar’s depth capability depends on the transducer installation, water and bottom conditions, and other factors .
RANGE - Upper and Lower Limits
Virtually any segment of the water can be displayed by using the upper
and lower limit feature. This lets you pick the shallow and deep range
limits that are shown on the screen, provided there is at least ten feet
between the upper and lower limit. For example, a range from 12 feet to
34 feet.
To change the upper and lower
limits, press the MENU ke y, then
select “Upper and Lower Limits”.
A screen similar to the one at right
appears. Upper Limit is highlighted. To select it, press the ENT
key. To select the lower limit,
press the down arrow ke y to highlight it, then press the ENT key.
Once a limit window is selected,
the range inside the window
changes to zeros. Use the arrow ke ys to both select and change the numbers in the window. Press the ENT key to accept the change. Press the
EXIT key when you’re finished. The Upper and Lo wer Limit menu erases
and the unit begins scrolling echoes across the screen using the new
range values.
Changing the upper and lower limits gives y ou far greater control ov er the
range. This feature lets you “zoom” the display in virtually unlimited combinations. Virtually any segment of the water, from the surface to the bot-
14
tom can be shown, which enlarges targets to best suit your fishing needs
and water conditions.
ZOOM
“Zooming” the display is a common method used to enlarge
small detail, fish signals, and the
bottom with its asscociated structure. This unit lets you zoom the
display quickly and easily by
pressing the ZIN key. Pressing it
once doubles the size (2X) of all
echoes on the screen. Pressing
it again quadruples the size of the
echoes (4X). The zoom bar on the
far right side of the screen shows which echoes will be displayed on the
screen when the ZIN key is pressed. For example, pressing the ZIN key
once will enable a 2X zoom which will show all echoes that are betw een
the top and bottom of the 2X zoom bar . Pressing the k ey 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 ZOUT key to return the display to the normal mode.
STOP CHART
To temporarily stop the char t from scrolling, press the MENU key, then
select “Stop Chart” from the menu and press the ENT ke y. Repeat these
steps to start the chart again.
CHART SPEED
The rate that echoes scroll
across the screen is called the
chart speed. It’s adjustable by
pressing the MENU key, then selecting “Chart Speed”. A sliding
knob adjustment appears on the
screen. The def ault is maximum.
Press the up or down arrow key
to adjust the speed, then press
the EXIT key to erase the menu.
DEPTH CURSOR
The depth cursor consists of a horizontal line with a digital depth box on
the right side. The numbers inside the box show the depth of the cursor.
15
The cursor can be moved to any
location on the screen, letting you
pinpoint the depth of a target.
To show the depth cursor, press
the MENU key , then select “Depth
Cursor”. Press the ENT k e y. The
cursor appears at the top of the
screen. Use the arrow keys to
move the cursor to the desired
depth.
Erase the depth cursor by pressing the EXIT ke y.
CHART D ATA
The digital information shown in
the upper left corner of the display along with the zone alarm
and zoom bar can be changed
using the Chart Data menu. To
use this menu, press the MENU
key, select “Chart Data Shown”
and press the ENT key. A screen
similar to the one at right appears.
The unit can show the digital
depth in large numbers (default), small numbers , or off . To change it, select the “Depth” label, then press the ENT key. Highlight the desired setting using the arrow keys , then press the ENT k ey.
To change any of the other settings, on this screen, select them using the
arrow keys , then press the ENT key to select them. Press the EXIT k ey to

T ransducer Frequency
This unit operates from both 200 kHz and 50 kHz. The default frequency
is 200 kHz. It’ s best f or use in shallow water. The 50 kHz frequency is best
for deep water, especially saltwater. Use the arrow keys to highlight the
desired frequency, then press the ENT key to select it.
Surface Clarity
The markings extending downward from the zero line on the chart are
called “surface clutter”. These markings are caused by wav e action, boat
wakes, temperature in v ersion, 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. The maximum depth that the surface clarity control can affect
is 75% of the selected depth range. For example, on a 0 - 60 foot range
with surface clarity control set to high, surface clutter will be reduced down
to 45 feet.
There are three levels of surf ace clarity av ailable: low, medium, or high. It
can also be turned off. The default level is low. To change it, highlight
“Surface Clarity” on the “Sonar Features” men u, then press the ENT k e y
to select it. Use the cursor keys to highlight the desired level of surface
clarity, then press the ENT key.
Noise Rejection
The automatic noise rejection system built into this unit constantly ev aluates the effects of boat speed, water conditions, and interference from
electrical and mechanical sources such as bilge pumps, engine ignition
systems and wiring, even engine vibration. It then works to reduce or
eliminate the negative effects on the sonar screen. This gives the best
display possible under most conditions .
The Noise Rejection system is an effective tool in combating noise. In
sonar terms, noise is any undesired marks on the display.
This unit has two lev els of noise rejection: normal and high. It can also be
turned off. The def ault is normal. To change it, highlight “Noise Rejection”
on the “Sonar Features” menu, then press the ENT key to select it. Use
the cursor keys to highlight the desired le vel of noise rejection, then press
the ENT key.

SONAR FEATURES (cont.)
Fish Symbols
The Fish Symbols feature identifies targets that meet certain conditions as fish. The microcomputer analyses all echoes and
eliminates surface clutter, thermoclines, and other signals that
are undesirable. In most instances, remaining targets are
fish. The Fish Symbols feature
displays 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 w ords, it displays a small fish symbol when it thinks a target is a small fish, a medium fish symbol on a
larger target, etc.
The 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 outwards from a group of limbs is the hardest object for the Fish Symbols
feature to distinguish from fish.
You may see Fish Symbols symbols on the screen when actually, there
are no fish. Practice with the unit in both the Fish Symbols mode and
without to become more familiar with the Fish Symbols feature .
The default for Fish Symbols is off. To turn the Fish Symbols feature on,
highlight “Fish Symbols” on the “Sonar Features” menu. Press the ENT
key to turn the Fish Symbols feature on. Any targets the microcomputer
determines are fish will be displayed as fish symbols.
Fish Depths
The Fish Depths feature shows the depth of a fish symbol when it appears on the display. This lets y ou accurately gauge the depth of targets.
This feature is av ailab le only when the Fish Symbols f eature is on.
The default for Fish Depths is off. To turn the this feature on, highlight
“Fish Depths” on the “Sonar Features” menu. Press the ENT key to turn
the Fish Depths feature on. (Note: If Fish Symbols is off, turning Fish
Depths on will also turn Fish Symbols on.)

unit, the sonar data shown on the
screen can be saved to the MMC .
This can be played back using the
sonar simulator at any time.
T o sa ve the chart data, press the
MENU key, then select “Log Sonar Chart Data”. The screen at
right appears.
To save data using the defaults on this screen, highlight “Start Logging”
and press the ENT key. You can change any of the def aults on this screen,
if desired. When finished, press the EXIT key .
