After commissioning, a calibration journey is required. During the jour-
ney, the speed signal (GAL) is automatically adapted to the
vehicle-specific data and the gyro sensor is automatically adapted
to the installation position of the unit.
The distance to be covered depends on the type of vehicle and the local
conditions.

Adequate GPS reception must be ensured for the calibra-
tion ride. This means at least 2-D FIX. With GPS FIX 3-D
the calibration will be quicker. However: a lower accuracy
of the GPS signal (2-D FIX) does not lead to a poorer cali-
bration, but instead will mean that the time and distance
needed for the calibration will increase.
