terminals or
wiring on the terminals are corroded, or the battery
needs transducer into the epoxy, twisting
and
turning
it to force
any air bubbles
charging.
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
greater
thanthewateryou
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.
Bottom echo
disappears
at
high speeds
or erratic
digital reading or
weak bottom echo while boat is moving
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
ability
to
find the bottom or
other
targets.
The technical term for this is Cavitation.
out from under the transducer face. The
face of
the
transducer should
be parallel with 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 in two
vertical columns plus
a
horizontal
row at the bottom. The
keys in the left column are used to enter numbers
and menu selections. The
keys in the right column activate the windows
feature and the basic sonar functions. The menu key
in the bottom
right
corner of the keyboard activates the first menu page. The
keys along the
bottom of the screen are used to activate the alarm menu, stop
the
chart,
and make menu selections with the arrow keys.

you access to the windows
mode, which lets
you customize displays.
SENS - Press this key
to
adjust
the unit's
sensitivity.

This
key
lets you adjust
the range
when the unit is in the manual
mode.
