7.5 TROUBLESHOOTING
The following is a brief guide to some of the problems you may experience while
using the chart plotter 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. 6.6.1).
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.
