3.4 Open water calibration

WARNING: Ensure you have sufficient open space for calibration
The open water calibration manoeuvres require a clear, familiar area of
water, with enough depth for your vessel. Ensure you are not likely to
collide with any vessel or other obstruction during calibration.
WARNING: Unexpected turns
The autopilot may make unexpected turns during open water calibra-
tion. Maintain a speed that will enable safe turns.
Ensure that the Initial setup and Dockside setup have been satisfactorily completed,
then navigate to a familiar area of open water, and carry out the separate Open water
calibration procedures for the autopilot and instrument systems, as necessary.
Sailing vessels should perform open water calibration under engine power.
Note:
You may exit the calibration process at any time by pressing
keypad. The next time you power up, you will be prompted to complete calibration.
