After installation of the feedback unit is complete and the linkage is fitted, have
the steering of the vessel turned lock to lock and ensure:
a)The direction (port or starboard) indicated on the top of the RFU is correct.
b)No undue mechanical strain is placed on the rudder feedback or linkage.
NOTE: THE AUTOPILOT WILL NOT FUNCTION CORRECTLY IF A
RUDDER FEEDBACK IS NOT FITTED, OR IF THE FEEDBACK IS
FAULTY OR INCORRECTLY ADJUSTED.
NOTE: THE RUDDER FEEDBACK UNIT IS FACTORY ALIGNED. THE
ARM SHOULD NOT BE REMOVED OR LOOSENED
UNNECESSARILY. IF ARM IS LOOSENED OR REMOVED,
VOLTAGE ALIGNMENT SHOULD BE CHECKED BEFORE USING
THE AUTOPILOT. THIS MUST BE DONE BY A COMPETENT
TECHNICIAN.
