TRUE NORTH CALIBRATION

When you do not know the declination angle, the true north
calibration function can be used to compensate for the
difference between magnetic and true north. All you need
to know is the direction of true north (this can be found from
landmarks in your immediate vicinity). Setting the true north
calibration makes the compass reading more accurate.
To set True North calibration:
1. Press and hold COMPASS to enter settings mode.
2. Press ALT / + or BARO / - to navigate to North mode.
3. Press TIME to confirm and move to the next setting.
4. Press ALT / + or BARO / - to change setting. The
setting options are as follows: ON / OFF; point to true
north.
5. Press TIME to confirm.
NOTE If the declination angle is turned ON, the True north
function will automatically turn itself OFF and vice-versa.
TIP Press COMPASS anytime to quickly exit.
