The rudder feedback calibration determines the rudder feedback's
direction.

Rudder test
This rudder test verifies the drive direction. It detects minimum
power to drive the rudder and reduces the rudder speed if it
exceeds the maximum preferred speed for autopilot operation.
Ú Note:
If the boat uses power assisted steering, it is important
that the engine or electric motor used to enable the power
assist steering is turned on prior to this test.
• Run the rudder test as described in the on-screen instructions
- Rudder should make a small movement within 10 seconds,
then follow up with travelling both directions
Failure to complete test will result in an alarm.
VRF calibration
Ú Note:
Only available if the rudder source is set to a virtual
rudder feedback.
