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.
MAINTENANCE
Your 105SX is designed to provide years of trouble free operation with
virtually no maintenance. Follow these simple procedures to ensure your
105SX continues to deliver top performance.
•If the unit comes into contact with salt spray, simply wipe the affected
surfaces with a cloth dampened in fresh water. Do not use a chemical
glass cleaner on the lens. Chemicals in the solution may cause cracking
in the lens of the unit.
•When cleaning the LCD protective lens, use a chamois and non-abrasive,
mild cleaner. Do not wipe while dirt or grease is on the lens. Be careful
to avoid scratching the lens.
