Virtual Feedback calibration
To perform the Virtual Feedback
calibration and rudder test you must
be able to view the movement of
the engines/drives (“rudder”).
The Virtual feedback calibration is
entered as a numerical value equal
to the physical rudder angle
observed at the hard over position.
Use the course knob to enter the
starboard and port rudder angle.
Rudder test
Activate the automatic rudder test
by turning the course knob

While observing the rudder
position, use the wheel to center the
rudder. Confirm by turning the
course knob clockwise.
The next step is to enter the correct
direction of the rudder movement.
Press and hold the TURN/DODGE
button. Observe the rudder
movement. Release the button after
3 seconds.
