MAINTENANCE
Maintenance for the Boundary Waters CLC-200 is very
simple. There, simply, is not that much to maintain. Because
of this, problems can sneak up on you if you're not careful.
The unit should be removed 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.
Spray the power connector pins and battery compartment
contacts with silicone to prevent this. Remove the
batteries before you put the unit away for storage.
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 soap An oily film can
develop which will cause weak readings.
Clean the face of the unit with a mild soap and a clean
soft towel. Don't submerge the unit when cleaning.
