Vexilar 107 Pro - Manual (Page 26)

MAINTENANCE
Maintenance for the 107 Pro is very simple. There, sim-
ply, 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 and battery terminals with sil-
icone to prevent this. Remove the connections before you
put the boat 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 cor-
rosion doesn't attack the wire. Periodically clean the face
of the transducer with a mild detergent. An oily film can
develop which will cause weak readings.
Clean the face of the unit with a mild soap. Don't sub-
merge the unit when cleaning.
