tLEAR DISTANCE LOG
To reset the
distance
log
to zero, press the MENU key, then press
the
key adjacent to the "More" label two times. Now press
the key
adjacent to the "Clear
Distance Log" label. This resets the distance
log and returns to
the chart display.
SPEAKER VOLUME
The speaker
volume has two steps -
low and high. The
speaker
volume is high when the unit is first turned on. To change
it, first
press the MENU key, then press the
key adjacent to the "More" label
two times. Now press the key adjacent to the "Set Speaker
Volume
Low" label. To switch back
to the high volume, repeat the above
steps.

NOISE REJECTION
The X-60's noise rejection feature is an effective tool in cdmbating
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
pro-
duces unwanted marks on the display.
The X-60 has a two step
nise
rejection system. Whed the unit is
turned
on, the
noiserejection is normal. If you have
noise problems
(identified by random lines or dots on the display), try changing the
noise rejection level to high.
To do this, first press:the MENU key, then the
key adjacent to
the
"More" label three
times. Now press
the key adjacent to the 1Set
Noise Rejection" label. The
screen below appears. Now
press
the
key adjacent to the "High" label. The screen will clear and return to
the chart screen. The noise
should clear from
the
display as new
echoes scroll across the screen. If
it isn't, you may
have a problem
with electrical wiring, engine, or transducer installation. Check
with
your local dealer, Lowrance service
center, or the
Lowrance factory
cu.tomer
service
department for help.
The X-60 has reverse polarity protection. No damage
will occur to the
unit if the power
wires are hooked up backwards. However,
the unit
will not work until you connect the
wiring properly.
Minimize electrical noise
by routing the power
cable
away from other
ppssible sources of electrical interference. One of the
largest noise
generators is the engine's wiring harness. For best
results, keep
the
power
and transducer cables away
from
the engine wiring. Bilge
pumps
and their wiring can also radiate noise, so keep
the cables
away from
them, if
possible.
VHF radio antennas and cables radiate RF energy
at high
power
levels. It is important to keep the power
and transducer cables away
from
them, also.
If qntèrference begins at slow boat speeds and gets
worse as the
spead increases, then the
probable cause is cavitation. This noise is
caused
by air bubbles passing over the
face of the
transducer-. It's
easy
to determine if this noise is electrical or cavitation. Stop the
boat, put
the engine in neutral, and increase the Rpm. If the noise
increases, then it's electrical, If it doesn't show on the display,
then
the
problem is cavitation. To solve this problem, move
the transducer
out
pf
the turbulent water flow. Adjust
the
bracket so smooth water
flows over
the transducer's face at all
boat speeds.
