It also is recommended to perform the Automatic tuning steering 
East or West, as this will yield the best balanced parameters. 
Note ! 
After the Automatic tuning has been completed the rudder must 
be controlled manually, as the autopilot has returned to STBY 
mode. 
Caution ! 
The Automatic tuning function will take control of the boat 
and perform a number of S-turns. It must always be performed 
in open waters at a safe distance from other traffic. The 
Automatic tuning function may take from 1 to 2 minutes to 
complete. To stop the Automatic tuning, press the STBY 
button. 
Activate the Automatic 
tuning, by rotating the course 
knob clockwise. The display 
will flash “Automatic tuning”.
After an Automatic tuning, there should be no need for further 
adjustments. “Fine tuning” of these parameters are made by the 
response control (see page 45). However, viewing or changing 
the parameters can be made from within the Parameters menu 
item. See also “Recall Autotune” on page 107. 
Proceed to the next menu item by pressing the STBD button, or 
return to Standby mode by pressing the STBY button. 
Transition Speed 
The transition speed is the speed where the autopilot will 
automatically change the steering parameter set from HI to LO 
parameters, or vice versa (page 23). 
The default setting of transition speed is 5 kts. 
It is recommended that you set the transition speed to a speed 
that represents the speed where the hull begins to plane, or the 
speed where you change from slow to cruising speed. 
The speed used for the automatic transition is obtained with the 
following priority: 
1. Speed through water from the speed log source. 
2. Speed Over Ground (SOG) from the GPS/Chartplotter. 
If no speed data is available, manual speed selection is required.
