4. Keep turning your boat until the display changes to show the
amount of deviation the autopilot has detected (this should take
between 1
1
/
2
t o2 complete circles). The deviation alternates with
the autopilot’s current heading every second.
Heading alignment
1. Use the -1 and +1 keys to increase or decrease the displayed
heading until it agrees with the heading on the boat’s steering
compass, or a known transit bearing.
2. Exit compass linearization and heading alignment and store the
compass correction/alignment values as follows:
• press and hold
standby for 1 second until the pilot beeps
• or, to exit without saving any new settings, press
standby
momentarily
Note: For installations where an ST50 or ST30 Steering Compass
instrument is connected to the SeaTalk bus, and the Steering
Compass has a fluxgate transducer connected, it is only necessary to
carry out the auto deviation correction on the Steering Compass
Instrument (refer to Steering Compass handbook instructions).
