set the MagnetIc DecLInatIon angLe
The angle between magnetic north and the true north direction is called
magnetic declination. The earth's magnetic poles fluctuate over time, and
it also varies from place to place. Find the magnetic declination on a map
or website, and then set the declination on this unit to offset the difference
between magnetic north and true north. Please note that if you fail to do this,
the readings you get from the compass could be in error.

90°, and press "MODE" button to
