The factory settings for Rudder,
Counter Rudder, Yaw and Turn Rate
are 3, 3, 1 and 6 respectively.
TO SELECT THE SLOW MODE, (if the
vessel is travelling at slow speed), press
the ADJUST key once followed by either
the up or down ARROW key until the
display reads 'SLOW'.
This will occur
automatically if the speed sensitivity is
turned on.
The Rudder, Counter Rudder, Yaw and
Turn Rate settings for the slow mode are
adjusted the same way as described
above.
The factory settings for Rudder,
Counter Rudder, Yaw and Turn Rate
are 5, 5, 1 and 6 respectively.
When in doubt about how to determine
the correct Rudder and Counter Rudder
settings for either the FAST or SLOW
modes, try the factory settings shown
above.
If you make a large turn, and you see
that the vessel overshoots the new
course more than once, try either
increasing the amount of Counter
Rudder by one setting, or reducing the
amount of Rudder by one setting. If this
does not solve the problem try it again.
If the vessel seems to stop turning before
you get to the new course, and then
slowly come up to it, try either decreasing
the amount of Counter Rudder or
increasing the amount of Rudder.

Rudder and Counter Rudder
adjustments.
If nothing seems to make the vessel
steer properly, or it steers properly on
some headings but not on others,
particularly north or south, it is almost
always a problem with the compass.
If the autopilot is using a Magnetic
Compass,
problems could be caused by
the compass not having been swung by
a qualified compass adjuster; the card
may be sticking because of a worn pivot;
or the compass may not have been
swung properly the first time.
On new steel vessels in particular, the
magnetism of the hull can change
dramatically over time, and it is not
uncommon to require the compass to be
swung twice in the first year. Also there is
a common misconception that aluminum
vessels do not require the compass to be
swung because aluminum is non-
magnetic. It is, but the welds where the
aluminum plates are joined become
magnetic because of the amount of
energy injected there. For this reason,
having the compass properly swung is
just as important on an aluminum vessel
as on a steel vessel.
If the autopilot is using a fluxgate
compass,
problems could be caused by
the compass being mounted too far from
the vessel’s center of pitch and roll. The
sensor's gimbal may be sticking; or the
vessel has such strong magnetism that a
compass adjuster is required to manually
swing the compass.
The
DODGE
keys may be used to avoid
logs or other obstacles in the water
ahead. Pressing one
DODGE
key will
cause the vessel to make a panic turn in
that direction. Pressing both
DODGE
keys when the vessel has turned far
enough to miss the obstacle, will make
the autopilot bring and hold the rudder to
dead ahead.
Release the
DODGE
keys to return the
vessel to the original course at the
programmed turn rate when the vessel is
clear of the obstacle. The Function
Indicator will show a 'd' until the dodge is
complete.
