BEARING: You may display bearing relative to true North (true
bearing) or relative to magnetic North (magnetic bearing).
MAG CALIB: The location of the magnetic pole is different from
the geographical North pole. This causes a difference between the
true and magnetic North direction. The difference is called mag-
netic variation, and varies by the observation point on the earth.
This unit is programmed with the earth’s magnetic variations. How-
ever, you may wish to further refine variation for a particular area.
If you enter compensation manually, be sure to change it when
magnetic variation changes.

tude or Loran LOPs.
