NOISE
Amajor causeofsonar

cases,
it cancompletely coverthe screen with blackdots, orcaUse theunit

Toeliminate orminimizetheeffectsofelectricalnoise,

example,turnonthe bilgepump

Ifyou findnoiseinterferencefromanelectricalinstrument, trollingmotor,
pump,
or
radio,tryto
isolatethe problem.Youcan
usuallyreroutethesonar
unit'spowercable and transducer cableawayfromthewiring that is
causing
theinterference. VHFradioantennacables radiatenoisewhen

Ifnonoise

certaineverythingexceptthe sonarunitisturned

thenstartthe

Increase theRPM withthe gearshift in neutral. Ifnoise
appears
onthO
display,the problemcouldbeoneofthree things;sparkplugs, alternator,
ortachometer wiring. Tryusing resistor spark plugs, alternatorfilters, or
routing the sonar unit'spowercableaway fromengine wiring. Again,
routing the powercable directly to the battery helps eliminate noise
problems.Makecertaintousethein-linefusesuppliedwiththeunitwhen

SPEED/TEMPERATURE SENSORS
The LCG-2400 accepts up to three temperature sensors which can
monitor surface water, live
well,air,and
virtuallyanyother temperature.
You do need to becareful whenpurchasing thetemperature sensors,
however. Each
temperature sensorhasitsown "address".Thesensors
arelabeled"Water", "T-2"
(orTemp-2),
and "T-3"(orTemp-3). If
youwant

For
