Simrad AP25 Autopilot

122 20221495F

Recommended speed during Automatic tuning varies with the

type of boat, but should not exceed 10 knots. It should be

performed in calm or moderate sea conditions.

Note ! Automatic tuning should not be performed at planing speed or in

following seas!

For displacement boats use a speed that is approximately half the

normal cruising speed (i.e. if cruising speed is 10 knots, perform

the Automatic tuning at about 5 knots).

The parameter values calculated during Automatic tuning

becomes the HI parameters. The LO parameters are

automatically set to 66% of the HI.

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

56). However, viewing or changing

the parameters can be made from within the Parameter menu

item. See also “Recall Autotune” on page

128.

Proceed to the next menu item by pressing the STBD button, or

return to Standby mode by pressing the STBY button.
