Diagnostic
DIAGNOSTIC
The GEONAV has a diagnostic program to verify its correct
performance, once the installation has been made, and detect
problems that may occur during the use of the unit. To access
this program, turn the unit on by keeping any key pressed
excepting
CLR .
The GEONAV will perform automatically a test of the entire
system; as soon as the memory test has been performed, the
program allows verifying whether each key works properly.
Keep the
CLR
key pressed for 3 seconds to exit, otherwise go on
with testing keys.
The diagnostic program allows verifying the correct connection
between the GPS receiver and the unit. The position sensor
should be operating and should transmit NMEA 0183
messages. If the receiver is working, a string of NMEA
messages will be dispayed; this indicates that the entire
system is working correctly.
Press
ENT to freeze the messages on the screen.
Press CLR to exit the diagnostic program.
ATTENTION: to perform a memory reset, switch the unit on holding the CLR key
pressed.
This operation allows deleting all the data saved by the GEONAV so
far and resetting it.
