28 SmartPilot Series Commissioning Guide

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):

• press and hold standby for two seconds to enter Calibration mode

• when you see the DISPLAY CAL screen, press disp until you see the

SEATRIAL CAL screen

• press auto to enter Seatrial Calibration

Note:

If you cannot access Seatrial Calibration, you need to disable the calibration lock.

This can be found in Dealer Calibration (see page 47).

2. The first page in Seatrial Calibration should be the SWING COMPASS

page. If this is not the case, use the disp key to page through the Seatrial Cal-

ibration items until you see SWING COMPASS
