Aligning the compass heading
Once the deviation is displayed, press
disp to move to the Heading Alignment (ALIGN
HDG) page, then:
1. Manually steer the boat on a steady course at a speed sufficient to hold the
course.
2. If you have a GPS connected to your SPX-5 Tiller system:
i. Increase the boat speed to more than 3 knots.
ii. Press
auto
. The SPX-5 Tiller system will then set the heading to agree with
the COG (course over ground) heading received from the GPS.
As many factors can cause a difference between heading and COG you must then
fine-tune the heading alignment so it matches the boat’s steering compass (or a
known transit bearing). To do this:
1. Use
-
1, +1, -10
and
+10
to adjust the displayed heading until it matches boat’s
steering compass (or a known transit bearing).
2. Hold down
standby
for 2 seconds to exit Seatrial calibration and save the new
compass settings.
Although the compass calibration removes most of the alignment error, small errors
(a few degrees) may remain. Once you have completed the initial compass
calibration, you can make further adjustments to the alignment without having to
swing the compass again.
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 more slowly and in more favorable
conditions.

Coarse adjustment: If COG is available from GPS, press to set autopilot heading to
COG value, then fine tune manually (see below).
Fine adjustment: If COG is not available (or after setting heading to COG),
align autopilot heading manually:
