Course as set on
Autopilot instrument is
different from ship’s
steering compass. If constant error, Autopilot
compass is not aligned with for-
aft line of boat. Use Compass setting [C6] [ADJ] to adjust
alignment of compass.
Variable error in heading
caused
by magnetic
interference.
Verify that the steering compass is
accurately corrected and then correct the
Autopilot compass as per installation
instructions.
Large errors not corrected by
above remedies or lack of
change in course set point with
different headings indicate a
defective compass.

"good" NMEA heading is used
until good data restored. Check for poor navigator installation
causing bad signal to noise ration. Check
for erroneous data as detected by
navigator. Revert to magnetic course only,
if situation cannot be corrected.
Course under NAV
steering is erratic. May appear when close to
waypoint due to GPS-S/A.
