Calibration procedure
If you know the direction to the North magnetic pole, you may go straight to Point 2.
1. To commence the calibration procedure simultaneously press both bottom push
buttons
each of the three axes (see Figs. 1, 2 and 3). Finish calibration by pressing the back/
return push button. To refine calibration proceed as per Point 2.
2. Find the North using the compass on the display and turn the receiver so that
the aerial points to the North (see Fig. 4). To commence the calibration procedure
simultaneously press the both bottom push buttons
Fig. 1
3. Carry out at least 10 rotations as per Figs. 5 and 6, whilst still pointing to the North.
For quality calibration, each single rotation should be carried out with a slight
deviation from the direction northwards (see Fig. 7). Greater number of and slower
rotations will result in better calibration. Press the back/return push button
finish.

WARNING: The accuracy of the navigation rosette depends on the correct
calibration of the digital compass. In the event that inaccurate indication of the
dog's direction from you occurs, carry out calibration again.
The digital compass calibration will be lost if the receiver is located in the vicinity
of another object's or device's magnetic field; in such event, the compass must
be recalibrated.
