[Declination]
1. The GH-561’s electronic compass indicates
magnetic north. Geographic north (true north) is
not exactly in the same direction. To get a more
clear idea when traveling, you need to enter the
declination between magnetic north and true
north. By default, the value is set to 0.
You can ignore this parameter by selecting
OFF. In this case, you assume that true north
and magnetic north is the same thing. This can
lead to significant errors of direction in some
regions (near the poles).
If you select MANUAL you have to enter the
declination value.
