will also compensate for offsets if there is a CD100/CDI35
connected to the boats own compass instead of an RFC35.
Activate the COMP ADJ feature by pushing MODE once.
Adjust the heading readout to agree with the known,
accurate heading by pushing < or >. The offset value can be
either positive or negative. Store value by pushing MODE.
The adjusted heading is flashing on the display, while the
offset value is shown on the bottom line.
Note ! The offset required may be as big as 90 degrees, caused
by the orientation of the compass when installed. 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 with the
compass is not accurate.
• The automatic calibration is not correct, and may be due
to a large magnetic influence near compass. (A relocation
may be needed.)

Automatic tuning
The display will read AUT TUNE. Autotuning is a new
dynamic function that enables the AP11 system to
automatically set up the steering parameters (Rudder,
Counter Rudder, Autotrim) 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 Settings
Menu.
Note ! Autotune is an optional procedure that is not required
for the AP11 to function. The AP11 is preset with
steering parameters that should steer most boats in the
30 - 50 foot range and Autotune may not be required if
the preset parameters steer your boat acceptably.
Recommended speed during Autotune is 5-10 knots.
Autotune should not be performed at planing speed. It is
recommended that the Autotune be done in an East or West
direction if possible, as these will yield the best balanced
parameters.
