Make sure the RF300 is installed and aligned as pr. instruction in 
section 3.6 (or eventually section 3.27 for LF3000). This 
function enables you to compensate for any non-linearity in the 
transmission between the rudder and the rudder feedback.  

 

Confirm Rudder feedback 
calibration to STBD by 
turning the course knob 
clockwise. 

Manually turn the helm/wheel to starboard until the rudder stops 
at starboard lock (H.O.). 

 

The value on the display is 
the angle read by the rudder 
feedback unit before any 
adjustment is made.  

If the actual rudder angle is different from that of the display, 
correct the reading by turning the course knob clockwise to 
increase the value or counter clockwise to decrease the value. 
See note. 
Advance to the next step by pressing the STBD button. 
Manually turn the helm to port until the rudder stops at 
maximum port rudder. 
Adjust the displayed angle the same way as for starboard rudder. 

Note ! 

Many boats have ±45° (90° H.O. - H.O.) rudder angle as 
standard. So if you are not making any adjustment to the display 
readout (i.e. not turning the course knob), the autopilot will set a 
(default) value of 45° to each side. However, you should always 
simulate an adjustment by tuning the course knob forwards and 
back again. This is necessary to prevent the rudder from hitting 
the end stops. 
Rudder zero may still be inaccurate and should be adjusted later 
during sea trial. 
Proceed to next menu item by pressing STBD button.
