13. TECHNICAL TESTS
13.0 SYSTEM TEST
If you have connected your chartplotter according to the instructions, and chosen the proper
menu selection for your device, and are still having problems with your chartplotter, the
extended auto-test should help determine the problem. Make sure the chartplotter is turned
Off. While pressing and holding any other key, turn the chartplotter On. A new menu will
appear on the display:

exit from any submenu press [CLEAR]. To exit from the System Test turn Off the
chartplotter.
13.0.0 RAM Menu (reset)
This test verifies the integrity of the memories and if desired during this test all the internal
memory can be erased and the default setting restored.
RAM Test
To verify the integrity of the RAM. If on the screen the message
ERROR appears, the RAM
is physically damaged. Contact your Dealer or STANDARD HORIZON.
RAM Clear
To clear internal memory. If the chartplotter exhibits unusual operations, 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

To confirm clear RAM press [ENTER] again (but if at this time you do not wish to clear RAM
press [CLEAR]).
