MAINTENANCE AND WARRANTY
MAINTENANCE
especially helpful in diagnosing input
voltage problems. The present input
voltage is displayed. If voltage
fluctuations or power supply in excess
of 20 VDC or less than 10 VDC is
suspected, use the diagnostic screen to
confirm input voltage. Often, small
outboard motors do not effectively
regulate voltage when operated at high
engine speeds.
Use Diagnostic while running the boat
at high speeds to show the voltage
gain. Also, if you are using the 105SX in
portable configuration or from the
trolling motor battery, Diagnostic can be
used to evaluate the health of the battery by showing the present
voltage. Voltage can also be viewed in the Trip Log view.
Total Time. The total time category indicates the total time the unit has
been in use since shipped from the factory. It is normal for some hours to
appear in the total time when the unit is new due to factory testing.
While this is often of interest to the user, it is primarily a diagnostic tool
for the repair technician should the unit need service.

glass cleaner on the lens. Chemicals in the solution may cause cracking
in the lens of the unit.
