5 Commissioning the Wheel Pilot
To complete the compass correction:
1. Press and hold
STANDBY for 1 second – a series of dashes will
cycle around the display.
Note: If you see a ‘CAL OFF’ message instead of the dashes,
calibration access has been prevented. Refer to page 66 for details.
2. Keeping boat speed below 2 knots, turn the boat in slow circles.
You should take at least 3 minutes to complete each 360°.
3. Keep turning your boat until the display changes to show the
amount of deviation the autopilot has detected. The deviation
alternates with the autopilot’s current heading every second.
Note: If the deviation exceeds 15° you should re-site the control unit
to a location less affected by magnetic interference.
