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 carry out automatically a
test of the whole system; as soon as the memory test is com-
pleted, the program will allow checking the correct operation
of the unit’s parts.
Press ENTER to run one test or CLR to skip it and pass to the
following test.
WARNING: The unit’s internal memory can be cleared by holding the CLR key
pressed when switching the unit on. This operation will delete all the settings stored
in the GEONAV and restore factory settings. Moreover, the routes, tracks and mark-
ers not saved on the CompactFlash™ cartridge will be deleted.
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.
