Diagnostic

DIAGNOSTIC
The GEONAV features a diagnostic program to verify its cor-
rect performance, once installed, and detect problems that
may occur during the use of the unit.
To access the diagnostic program, hold the ENTER key pressed,
while pressing the PWR key.
The GEONAV will switch on and execute automatically the
diagnostic program. After displaying the system's software
releases, it will start carrying out the memory test.
As soon as the memory test is completed, the program will
test the NMEA 0183 port, the CompactFlash™, the external
GPS device, the keyboard, the backlight, the LCD and the
audio output. Press ENTER to run each test or CLR to skip to the
next test.
When testing the NMEA 0183 port, hold the ENTER key pressed
to freeze on the screen the messages sent by the GPS device
or the depth sounder, then release it to keep on displaying
any new message.
When testing the keyboard, press CLR twice to exit.
Once terminated all tests, press ENTER to re-boot the unit.
WARNING: The internal memory can be cleared by pressing simultaneously the
PWR and CLR keys while holding the CLR key pressed until the "Erase backup
procedure" message pops up. Press CLR to cancel the operation, or ENTER to
confirm it. This operation will delete all the settings stored in the GEONAV and restore
factory settings.
NOTE: In case of damaged cartridge or abnormal power spikes, the unit might lock,
requiring a power shutdown to restart. In that case, the unit can be turned off without
the need of detaching the power or the batteries, but by simply holding the PWR key
pressed for more than 9 seconds.
