Calib. Rudder

Initiates a procedure that establishes the maximum range of movement of the rudder and calibrates the rudder-position sensor. If an error appears during calibration, there may be an issue with the actuator. If the error persists, contact Garmin^® product support.

Calib. Center

Max. Port Angle

Allows you to enter the angle at which your rudder turns furthest port.

Max. Stbd. Ang.

Allows you to enter the angle at which your rudder turns furthest starboard.
