• Compass off set adjustment, used to compensate for a fi xed off set in the fi nal heading
readout
• Wind calibration to compensate for a fi xed mechanical off set of the Wind vane
• Boat speed calibration
• Transition HI/LO speed setting (the speed at which you want to change the set of steering
parameters)
• Automatic tuning of the steering parameters
• Setting the seastate fi ler
• Saiboat setup
Compass calibration
Before the compass calibration is started, make sure that there is enough open water around
the vessel to make a full turn.
The calibration should be done in calm sea conditions and with minimal wind to obtain good
results. Follow the on-screen instruction, and use about 60-90 seconds to make a full circle.
During the calibration, the compass will measure the magnitude and direction of the local
magnetic fi eld.
• If the local magnetic fi eld is stronger than the earth's magnetic fi eld (the local fi eld is reading
more than 100%), the compass calibration will fail
• If the local fi eld is reading more than 30%, you should look for any interfering magnetic
objects and remove them, or you should move the compass to a diff erent location. The
(local) fi eld angle will guide you to the local interfering magnetic object.
 Calibration
must be made on the compass that is active for the autopilot. If another model
compass from B&G or another manufacturer is installed, refer to the instruction for that com-
pass regarding calibration.
 Note:
In certain areas and at high latitudes the local magnetic interference becomes more
signifi cant and heading errors exceeding ±3° may have to be accepted.
Compass mounting off set
After compass calibration, the diff erence between the compass lubber line and the boat's
center line should be compensated for.
