Recommended speed during Automatic tuning should not exceed 10 knots. It should be
performed in calm or moderate sea conditions. For displacement boats use a speed that is
approximately half the normal cruising speed (i.e. if cruising speed is 10 knots, perform the
Autotune at about 5 knots).
Select Autotune to begin the tuning process. Press 1º RIGHT to confi rm Autotune.
After the Autotune has been completed the rudder must be controlled manually, as the
autopilot has returned to Standby mode. The Automatic tuning function will take control of
the boat and perform a number of S-turns.
¼ Note:
Autotune must always be performed in open waters at a safe distance from other
traffi c. The Automatic tuning function may take from 2 to 3 minutes to complete. To stop the
Autotune, press the 1º LEFT key.
After the Autotune process has been completed, ‘Finished’ will be shown on the screen and
there should be no need for further adjustments. Fine tuning of these parameters are made
by the response control.
Rudder gain
Rudder gain is the ratio between the commanded angle and the heading error.
Too little

Too much
rudder gain
Set Course
• Too little Rudder gain and the autopilot fails to keep a steady course
• Too much Rudder gain gives unstable steering and reduces speed
• Low speed requires more rudder gain than high speed
