7.5 TROUBLESHOOTING
The following is a brief guide to some of the problems you may experience
while using the chartplotter with common solutions.
7.5.1 PROBLEMS AND SOLUTIONS
The chart plotter does not turn On — Make sure that the correct voltage (10-35
volt dc) is present. Check also that the polarity is correct. Refer to the Par. 2.2.
The chart plotter does not turn Off — If, after a 'POWER' pressure (for at least 3
seconds) the chart plotter does not turn Off, then turn Off the voltage.
The chart plotter does not respond to any command — Try to turn Off, and then
turn On. If the problem persists, erase the memory (see Par. 7.6.1).
The chart plotter does not get a valid fix — Make sure that no metal obstacle is
placed around the chart plotter acting as a shield for the antenna. If, after 15 minutes,
the chart plotter does not get the fix, turn it Off and On again.
The chart plotter screen becomes very dark after a long exposure to direct sun-
light — Control the contrast (see Par. 2.3).
7.5.2 IF YOU NEED ASSISTANCE
The list above should allow you to solve most of the operating problems you
are likely to encounter. Simply disconnecting the chart plotter from power for a

If this does not help, you can try one additional memory clear option. This
is a factory default RAM Clear that should only be tried after all other attempts have
