7. Maintenance

This chapter gives information on routine maintenance and problem solving associated with the
chart plotter.

7.1 SYSTEM TEST

If you have connected your position-finding device according to the instructions, and chosen
the proper menu selection for your device, and are still having problems with your chart plotter,
the extended auto-test should help determine the problem. Make sure the chart plotter is turned
Off. While pressing and holding any other key, turn the chart plotter On. A new menu will appear
on the display.
Use the cursor key to select the desired test: this will display in reverse video. To choose the
test press [ENTER]. To exit from any submenu press [CLEAR]. To exit from the System Test
turn Off the chart plotter.
7.1.1

RAM Menu

RAM clear: Clears internal memory. If the chart plotter exhibits unusual behaviour, or appears
to be malfunctioning, it may be possible to correct the problem by clearing RAM. This operation
will erase all Marks, Routes, stored Track plots and destinations. It will also return all selections
(Input Data Format, Autopilot selection, etc.) to original default values. Before this step, you
have the option of saving user Marks, Track history and Routes to a User MEDIA (this is an
optional purchase from your dealer). To confirm to clear RAM press [ENTER] again (but if this
time you do not wish to clear RAM press [CLEAR]).
7.1.2

DIM Menu

you press the left key the contrast will increase.
