Automatic tuning
Dial in the correction by turning the course knob to offset the
compass heading to agree with a known heading or bearing. The
offset value can be either positive or negative.
Note !
If an OFFSET still exists after having accounted for the
mechanical offset, one of the following problems may still exist:
•
The heading reference that you are comparing the compass is
not accurate.
•
The automatic calibration obtained by the compass is not
correct, and may be due to a large magnetic influence near the
compass (a relocation may be needed) or too much waves
during calibration.
Proceed to the AUTOTUNE function by pressing the STBD [>]
button, or return to STBY mode.
Automatic tuning
AUTOTUNE is a dynamic function that enables the AP20
system to automatically set up the two main steering parameters
(Rudder, Counter Rudder) for the boat. The scaling factors of the
parameters are also set automatically as a function of the boat
type selection performed in the Dockside menu.
Note !
Autotune is an optional procedure that is not required for the
AP20 to function. The AP20 is preset with steering parameters
that should steer most boats in the 30 - 80 foot range and
Autotune is not needed if the preset parameters steer your boat
satisfactory.
