INSTALLATION
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 certain there is
enough room behind the unit to attach the power and other cables.
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.Next, pass the power cable down through the hole.Fill
the hole with a marine sealant.You can now wire the power cable.

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 for the NMEA/DGPS interface.See
belowforNMEA/DGPSwiringinstructions.The powercablehas two wires
- red and black.The black wire connects to the battery’s negative termi-
nal.Theredwireis the positivewire.Connectitto 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 bat-
tery.This will protect the both cable and the unit in case there is a short
circuit.Use a 6-amp fuse.
IMPORTANT!
Do not use this product without a 6-amp fuse connected to the power
cable! Failure to use a fuse will void your warranty.

To prevent electrical interference, route the power, 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 away from it, also.
NMEA/DGPS
NMEA is a standard communications format for marine electronic equip-
ment. For example, an autopilot can connect to the NMEA interface on
the LCX-16CI and receive positioning information.
DGPSisanacronymforDifferentialGlobalPositioningSystem.Themost
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/DGPSWiring
The LCX-16CI has two NMEA 0183 version 2.0 ports.Com port one can
beusedforeitherNMEAorDGPS,ComporttwoisforNMEA output only.
Comunicationsport one uses the yellowwire wire fortransmit,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 for general wiring connections.Read your other
product’s owner’s manual for more wiring information.

The LCX-16CI can accept position information from any GPS receiver
that transmits NMEA 0183 data.Use the wiring diagram shown above
for NMEA input to the LCX-16CI.
See page 25 and 26 for NMEA and DGPS com port setup instructions.
Accessory Connections
The rear of this unit has three connectors:Power/Data, GPS, andTrans-
ducer.The power cable connects to the Power/Data connector, the cable
from the GPS module goes to the GPS connector, and the transducer
plugs into theTransducer connector.
Speed/Temperature Connections
This unit can use a speed sensor in addition to up to three temperature
sensors.
Alltransom-mount“Skimmer”transducershavea temperaturesensorbuilt
into them. To add another temperature sensor besides the one in the
transducer requires a MY-4X“Y” adapter cable and aTS-2X temperature
sensor.The transducer plugs into one end of the MY-4X, theTS-2X tem-
perature sensor plugs into another, and the last end plugs into the SO-
NAR port. The TS-2X temperature sensor has an extra connector for a
TS-3X temperature sensor. This lets you have three temperature sen-
sors, if desired.
Note: Do not combine the temperature sensors in any order other than
shown on the nextpage.Forexample,do not use twoTS-3X temperature
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 for.

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 you see this detail,
but it can also clutter the screen with many undesired signals.Typically,
the best sensitivity level shows a good solid bottom signal with Grayline
and some surface clutter.
The sensitivity is adjusted to keep a solid bottom signal displayed, plus a
little more when the unit is in the automatic mode.This gives it the capa-
bility 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.
Toadjustthe sensitivity,pressthe
MENUkey,thenselect“Sensitiv-
ity”.The screen at right appears.
The sensitivity control has a ver-
ticaladjustmentbar.Thenumber
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 value.You can also
see the difference on the chart record as it scrolls.When the sensitivity is
at the desired level, release the key.
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 key.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 turn this on, press the MENU key, then

13
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 youdistinguish betweenstrongandweakechoes.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 andtheother
without,then the targetwithcolor
is the stronger signal.This helps
distinguish weeds from trees on
thebottom, orfishfromstructure.
Colorline is adjustable. Since
Colorline shows the difference
between strong and weak sig-
nals,adjusting thesensitivity 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 you.
Toadjustthe Colorline level,press the MENU key,thenselect“Colorline”.
The screen above appears. Use the up or down arrow keys to adjust the
color level.You can see the change on the chart record as you press the
keys.After you’ve finished, press the EXIT key to erase the menu.
RANGE - Automatic
Whenturned on forthe first time,

selecting the range, press the EXIT key to erase the range menu.
NOTE:The sonar’s depth capability depends on the transducer installa-
tion, 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 key, then
select“Upper and Lower Limits”.

binations.Virtually any segment of the water, from the surface to the bot-

15
tom can be shown, which enlarges targets to best suit your fishing needs
and water conditions.
