1.7 Connection of the GPS receiver

To check whether GPS data is being received, switch the operating mode
switch to position F (GPS diagnosis).

The status LED now indicates the operating state of the GPS.
LED is illuminated red:
LED flashes yellow:

LED is illuminated green:
In halls or buildings and under roofed areas, reflections of the GPS signal can occur.
This can have a significant effect on the accuracy of the positioning, and theft alerts
can be triggered although the vehicle has not been moved.
To prevent such alerts we recommend disarming the geofence function if the vehicle
is parked in a building or under a roof.

To do this, send an SMS with "fence off" to the number of the GSM module.
GPS not connected
Repeat the connection procedure with the power
supply disconnected. If this is not successful, the GPS
receiver may be defective.
GPS data is being received, however without a valid position.
If the status LED is still flashing after 5 minutes,
either the receiver is mounted at a position that
makes GPS reception impossible, or the vehicle
is parked under a roofed area, for example.
GPS position OK.
Switch the operating mode switch back to the ini-
tial position. If the LED is now illuminated red, a SIM
card has not been inserted. Additional LED states
are described in chapter 1.10.
