4.3.1. DECLINATION

You can compensate for the difference between true north
and magnetic north by adjusting the compass declination.
The declination can be found, for example, from sea charts or
topographic maps of your local area.

4.3.2. CALIBRATE

Because of changes in the surrounding magnetic fi eld the
D9 electronic compass occasionally needs to be re-calibra-
ted. During the calibration process the compass adjusts itself
to the surrounding magnetic fi eld. As a basic rule, you should
calibrate the compass when it does not seem to operate pro-
perly, or after replacing the D9 battery.
