Compass calibration
If the Module was exposed to a strong magnetic field or was not
in use for a long time, the compass accuracy may diminish.
To bring the compass into working condition:
ƒ Select
Cd 17
in the Setup mode
ƒ Keeping the unit horizontally, perform one full rotation
around vertical axis within half a minute and then one full
rotation around vertical axis with device upside down
during half a minute.
ƒ If one rotation does not restore calibration – perform two
rotations.
The normal compass functioning will be restored.
Depending on the version of the on-board software, during
calibration LCD will show either time countdown in seconds
from 59 to 1 or flashing word CAL.
To ensure azimuth measurement accuracy calibrate compass
after changing the battery.
