turning
it to force

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
powerand
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 transducerand
powerconnectors.
Make certain both are
securely plugged
in to the
unit.
Weak bottom
echo,
digital readings
erratic,
or no fish
signals:
1. Make certain
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 ismounted inside the
hull,
be
sure it
is
shooting through only
one
layerof fiberglass
and that it is
securely
bonded tothe hull. Do NOT use RTV silicone rubberadhesiveorMarinetex
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
will flash
continuously.
It
may change
the
range
to limits far

are in. If this
happens, placethe
unit in the manual
mode,
then
change
the
range
to a realistic
one, (for example,
0-100
feet)
and
increase the
sensitivity. Asyou
move
into
shallowerwater,
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.

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

The technical term for this is Cavitation.
out from under the transducer face. The
face of
the

hull,
with a minimum amount of
epoxy
between the
hull and transducer. After the
epoxy dries,
route the
cable to the
X-55A.
KEYBOARD
The
keyboard
has
keys arranged
