standby
for 2 seconds to exit calibration and save
the new settings.
Note: Setup options are always saved on exit.
Adjusting the heading alignment
You should always check the compass alignment after completing the
deviation correction procedure (swinging the compass). After you
have completed the initial deviation correction procedure, you can
make adjustments to the alignment as often as you wish without
swinging the compass again.
Although the compass deviation correction procedure removes most
of the alignment error, small errors (of the order of a few degrees) will
probably remain, that vary depending on the heading.
Ideally, you should check the heading reading against a number of
known headings, plot a deviation curve, and determine the heading
alignment value that will give the lowest average alignment error.
You can then enter this value on the Heading Alignment screen, as
described above.
If the average heading error is more than 5°, you should perform the
compass deviation correction procedure again, circling slower and in
move favorable conditions.
Checking autopilot operation
After calibrating the compass, familiarize yourself with autopilot
operation:
1. Steer onto a compass heading and hold the course steady.
2. Wheel Pilot: Engage the wheel drive clutch.
Tiller Pilot: Place the push rod end over the tiller pin.
3. Press
auto
to lock onto the current heading. The autopilot should
achieve a constant heading in calm sea conditions.
4. Use the
-1
,
+1
,
-10
and
+10
keys to check that the autopilot alters
the course to port and starboard in multiples of 1° and 10°.
5. Press
standby
and disengage the autopilot to return to hand
steering:
•
Wheel Pilot: disengage the wheel drive clutch by rotating the
clutch lever anti-clockwise
•
Tiller Pilot: remove the drive unit from the tiller pin (if
required, retract the push rod using
-1
,
+1
,
-10
and
+10
keys)
