Aligning the compass heading
1. Once the deviation is displayed, press
disp
to move to the Heading Align
ment page (
ALIGN HDG
).
2. Manually steer the boat on a steady course at a speed which enables you to
hold that course.
3. If you have a GPS connected to your SmartPilot:
• increase the boat speed to more than 3 knots
• press
auto
: the SmartPilot 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 (such
as tides and leeway affecting the boat) you must then finetune the head
ing alignment so it matches the boat’s steering compass or a known tran
sit bearing
4. Use
1, +1, 10
and
+10
keys to adjust the displayed heading until it matches
boat’s steering compass or a known transit bearing.
5. Press and hold
standby
for 2 seconds to exit Seatrial Calibration and save
the new compass settings.
