8.1

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 prob-
lems 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.

RAM Menu

RAM Test: Verifies the integrity of the RAM chips. If on the screen the message
"ERROR" appears, the RAM is physically damaged.
RAM Clear: Clears internal memory. If the chart plotter exhibits unusual behav-
iour, 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 C-CARD (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]).

DIM Menu

Contrast: Each time you press the cursor key to right, the screen will decrease
brightness, when you press the left key the brightness will increase.
Backlight: Sets the backlight. It operates in similar mode as Contrast.

Cartridges

Background ROM: Tests the WorldWide Background.
C-CARD Test: Tests the C-CARD. There are four possible situations:
If there is a C-CARD inserted in the slot and there is not a malfunction,
♦
the name of the C-CARD zone and the message "OK" are shown
If there is a C-CARD inserted in the slot, but it is damaged C-CARD, the
♦
name of the C-CARD zone and/or the message "Faulty" are shown
If there is not any C-CARD inserted in the slot, the message "not present"
♦
is shown
If there is a User C-CARD inserted in the slot, the message "USER
♦
C-CARD" is shown
C-CARD Connector: While a C-CARD is inserted in the slot, if the counter in-
creases, there is a malfunction reading it.
