Calibrating the Compass
Compass calibration is the process used with electronic digital compass to
separate the earth's magnetic field from stray magnetic fields emitted by
your vehicle. Calibration is necessary to ensure accurate compass
readings.
To perform compass calibration:
1. In Easy mode, press the Page button to display
the Compass page.
2. Press the Menu button to display the menu
options.
3. Use the navigation keys to select Calibration
and press OK to confirm.
4. The compass starts calibrating. This takes 15
seconds. Place the GM-120 on a level surface
and start rotating the unit through 360 degrees
three times every 5 seconds.
Note: This function just for the models integrated the electronic compass,
the GM-120B and GM-120C.
