MAINTENANCE
Permanent Mount
With permanent mount applications, the power cord is left connected
to the source, the transducer is not easily removed, and the gimbal brack-
et is screwed to the seat, deck, or dash. Under these conditions mainte-
nance is very simple because nothing changes once the unit is installed.
Because of this, problems can sneak up on you if you're not careful.
The unit should be removed from the bracket whenever the boat is
parked to guard against theft. Don't store it in a place that may fill with
water.
Power connections need constant checking. Corrosion can develop and
cause intermittent or loss of operation. Connections made to battery posts
need extra attention because of the battery acid.
The transducer should be checked for scratches and cracks which can
reduce the units sensitivity. Cuts or breaks in the cord should be repaired
as soon as possible so corrosion doesn't attack the wire. Periodically clean
the face of the transducer with a mild detergent. An oily film can devel-
op which will cause weak readings.
Portable Setups
In portable applications the unit is generally mounted to a carrying
case and the transducer is frequently removed, as is the power. These
conditions can cause more wear and tear than a permanently mounted
unit.
In addition to the previously mentioned maintenance items, be sure to
check for broken or pulled wires, loose screws or hardware, and battery
condition.
