Commissioning
Used to calibrate your boat's steering (cable steer or hydraulic steering) with the NAC-1.
Ú Note:
The autopilot must be commissioned prior to first use and any time after autopilot
default settings have been restored.
Steering response
Used to increase or decrease the steering sensitivity. A low response level reduces the rudder
activity and provides a looser steering. A high response level increases the rudder activity and
provides tighter steering. A too high response level will cause the boat to make S
movements.
