3.3.4. Compass
The compass menu includes functions for either calibrating the compass or setting its
declination.
Calibrating the compass
You should calibrate the compass if it does not seem to work well, for example, when
it displays the wrong compass heading or the heading changes too slowly. You
should also calibrate the compass after replacing the battery.
Strong electromagnetic fields, such as electric lines, loudspeakers and magnets, can
affect the compass calibration. Therefore calibrate the compass if your Suunto X6/
X6M has been exposed to these fields.
You should also calibrate the compass before a long trip.
NOTE: Calibrate the compass before using it for the first time.
NOTE: Remember to hold the Suunto X6/X6M level during the calibration.
To calibrate the compass:
1. In the Function menu, scroll to Compass with the arrow buttons and press Suunto.
