will appear in the center of the display. 32-
segment ring around the outside will animate clockwise to
prompt the user to rotate the instrument during calibration.
3.
Rotate the instrument clockwise for two complete rotations
of approximately 15-seconds per rotation.
NOTE:
For the optimum accuracy, the compass must be
held completely level during the calibration process. We
recommend placing the unit on top of a drinking glass
while performing the calibration as this will make it
easier to keep the compass level.

MAGNETIC DECLINATION
A magnetic compass points to the earth’s magnetic north pole. Depending on your
location, this may be different from True North. Adjusting the Magnetic Declination
allows you to compensate for this variation. Magnetic Declination for an area can be
found on topographical maps. Declination can change over time and distance. Make
sure the source for your declination settings is up to date. The following websites are
good sources for finding local Magnetic Declination.
