5 Commissioning the Wheel Pilot
Heading alignment
1. Steer your boat on a straight course, then use -1 and +1 to adjust
the displayed autopilot heading until it agrees with the boat’s
steering compass or a known transit bearing.
2. Exit compass linearization and heading alignment and store the
compass correction/alignment values as follows:
• press and hold
STANDBY for 1 second until the pilot beeps
• or, to exit without saving any new settings, press
STANDBY
momentarily
Note: For installations where an ST50 or ST30 Steering Compass
instrument is connected to the SeaTalk bus, and the Steering
Compass has a fluxgate transducer connected, it is only necessary to
carry out the auto deviation correction on the Steering Compass
Instrument (refer to Steering Compass handbook instructions).
Further adjustments to heading alignment
If the heading alignment requires further adjustment after the initial
sea trial:
1. Enter Compass Deviation Correction by pressing
STANDBY for
1 second.
2. Press
AUTO to skip Deviation Correction and proceed to Heading
Alignment.
3. Adjust the heading as described above.
4. Press and hold
STANDBY for 1 second to save changes and exit.

should achieve a constant heading in calm sea conditions.

multiples of 1° and 10°.
