TherefOre,
after

pass
the transducer
connector
up
through
the hole from
under the dash. Then
drop
the
power
cable down
from the front side
of the dash. Slide the bracket

POWER CONNECTIONS
The
X-25 works from a 12 volt DC
system
only.
For the best
results,
run the
power
cable
directly
to the boat's
battery.
Keep
the
power
cable
away
from
other boat
wiring, especially
the
engine's
wires. This
will
give
the best
isolation from electrical noise. If the
supplied
cable is
not
long enough
to reach
the
battery; splice
#18
gauge
insulated wire
to it. You can attach
the
power
cable to an
accessory
or
power buss,
however,
you may
have
problems
with electrical interference.
See
page
25 for more information on
electrical noise.
This unit
has reverse
polarity protection.
No
damage
will occur if the
power
wires are reversed.
However,
the
unit
will
not work until the
wires are
attached
correctly.

SONAR
TROUBLESHOOTING
Unit won't turn on:
I.
Check the
power
cable's
connection at the unit. Also check the
wiring.
2. Make
certain the
power
cable is wired
properly.
The red wire connects
to the
positive battery
terminal,
black to
negative
or
ground.
3. Check the
fuse.
4. Measurethe
batteryvoltage
atthe unit's
powerconnector.
It
should be at least
ii volts. If it
isn't, thewiring
to the unit is
defective,
the
batteryterminals
orwiring
on the terminals are
corroded,
or the
battery
needs
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.
Re-routing
the
power
and 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
transducer and
power
connectors. 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 afilmto form on the
transducer,
reducing
its effectiveness. If the
transducer is mounted inside the
hull,
be sure it is
shooting through only
one
layer
of
fiberglass
and that it is
securely
bonded to the
hull. Do NOT use RN silicone
rubber adhesive or Marinetexid.
