The following display is presented when accessing the COMPASS OFFSET
entry screen:
INSTALLATION
Offset ?: 000°
Heading : 194°
Dial in the correction by turning the course dial to offset the RFC35 heading
to agree with the known, accurate heading. 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 RFC35 is not accurate.
•
The automatic calibration obtained by the RFC35 is not correct, and may
be due to a large magnetic influence near the RFC35. (A relocation may
be needed.)
Caution !
Do not compare with GPS’ COG since your GPS is showing course and
not heading.
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 AP35 system to
automatically set up the two main steering parameters (Rudder and 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 Settings menu.
Note !
Autotune is an optional procedure that is not required for the AP35 to
function. The AP35 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 varies with type of boat, but should
not exceed 10 knots. Autotune should not be performed at planing speed!
For displacement boats use a speed that is about half the normal cruising
speed (i.e. if cruising speed is about 10 knots, do the Autotune at about 5
knots). The parameter values calculated during this Autotune becomes the
LO speed parameters. The HI speed parameters is automatically set to 66%
of the LO speed parameters. It is recommended that the Autotune be done in
an East or West direction if possible, as these will yield the best balanced
parameters.
WARNING !
The Autotune function will take control of the boat and perform a
number of S-turns. It must always be performed in open waters with
sufficient safe distance to other traffic. The Autotune function may
take from 1 to 2 minutes to complete.
