Calibrating the compass
Note:
This section does not apply if you have connected an NMEA compass to your Smart
Pilot. Refer to the handbook supplied with the NMEA compass for information about cali
bration.
Deviating magnetic fields can cause significant compass errors on your boat. The
correction procedure reduces these errors to a few degrees, so you
MUST
perform this procedure as the first item in your initial seatrial. The SmartPilot will
then automatically correct the compass.
CAUTION:
Failure to complete the deviation correction will impair your
SmartPilot’s performance on some compass headings.
The deviation correction procedure (commonly called “swinging the compass”)
involves turning your boat in slow circles so the SmartPilot can determine the
deviation and calculate any correction required. You must carry out this procedure
in calm conditions and preferably on flat water.
Initial procedure
Automatic compass deviation correction
1. With the pilot in Standby mode, enter Seatrial Calibration as follows (see the
following illustration):

Note: If you cannot access Seatrial Calibration, you need to disable the calibration lock.
This can be found in Dealer Calibration (see page 43).
