6.5 TROUBLESHOOTING
The following is a brief guide to some of the problems you may experience
while using the chartplotter with common solutions.
6.5.1 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. 6.6.1).
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 sun-
light — Control the contrast (see Par. 2.3).
6.5.2 HELP
If you want to activate a function, the chartplotter has an help on line:
'MENU' + "Help" + 'ENTER'
Use 'ZOOM IN' and 'ZOOM OUT' to select the previous and the next
page.
6.5.3 IF YOU NEED ASSISTANCE
The list above (see Par. 6.4.1) should allow you to solve most of the operat-
ing problems you are likely to encounter. Simply disconnecting the chartplotter
from power for a moment 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
