9. Press and hold
STANDBY
for 2 seconds to exit calibration and save
the new settings.
Note:
Setup options are always saved on exit.
Further Heading Alignment Adjustment
You should always check the compass alignment after swinging the
compass. However, once the initial deviation correction procedure
has been performed, 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, you will probably be left with small errors (of
the order of a few degrees) that will 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.
This value can then be entered 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.
Checking Autopilot Operation
Having calibrated the compass the following procedure is
recommended to familiarise yourself with autopilot operation:
1. Steer onto a compass heading and hold the course steady.
2. Press
AUTO
to lock onto the current heading. A constant heading
should be achieved in calm sea conditions.
3. Use the
-1
,
-10
,
+1
and
+10
keys to alter course to port or starboard
in multiples of 1° and 10°
4. Press
STANDBY
and disengage the autopilot to return to hand
steering.
