6.4 TROUBLESHOOTING
The following is a brief guide to some of the problems you may experience
while using the chartplotter with common solutions.
6.4.1 PROBLEMS AND SOLUTIONS
The chartplotter 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 chartplotter does not turn Off — If, after a 'POWER' pressure (for at least 3
seconds) the chartplotter does not turn Off, then turn Off the voltage.
The chartplotter does not respond to any command — Try to turn Off, and then
turn On. If the problem persists, erase the memory (see Par. 6.5.1).
The chartplotter does not get a valid fix — Make sure that no metal obstacle is placed
around the chartplotter acting as a shield for the antenna. If, after 15 minutes, the
chartplotter does not get the fix, turn it Off and On again.
The chartplotter screen becames very dark after a long exposure to direct sunlight
— Control the contrast (see Par. 2.3).
6.4.2 WHEN NOTHING ELSE WORKS
The list above should allow you to solve most of the operating problems you
are likely to encounter. Simply disconnecting the chartplotter from power for a mo-
ment may solve your problem as well.
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
been made. When using the RAM Clear feature, you will loose all user stored infor-
mation and the chartplotter will default to factory settings. Before this step, you have
the option of saving user Marks, Track history and Routes to a Floppy Disk (this is
an optional purchase from your dealer). To perform a RAM Clear see Par. 6.5.1.
6.4.3 IF YOU NEED ASSISTANCE
If you still need assistance, call your local dealer, reporting the Software Re-
