VRF calibration determines the direction of rudder movement, the
minimum output required to move the rudder and the voltage to
rudder speed ratio.
To perform the VRF calibration you must be able to view the
movement of the rudder.
• Follow the on-screen guided steps until the VRF calibration is
completed.
Ú
Note:
When you get asked if the rudder moved you may have
to select no several times to ensure the pump provides enough
power to turn the motor at high vessel speed.
