about three or four full circles for calibration. Note
that the boat will turn to starboard with the degree set at MANUAL RUDDER LIMIT on

calibration starts automatically. For MANUAL, turn the boat to starboard or port in a circular
course. Take about two minutes to complete the circle.
If the calibration fails, the message “CALIBRATION UNCOMPLETED, RETRY?” appears. To
retry the calibration, press the course control knob.
To stop the calibration while the ship is turning, press any key to show the message “STOP
CALIBRATION”. Press any key again to return to the SEA TRIAL menu.
When the calibration is successfully completed, the message “CALIBRATION
COMPLETED” appears. Press any key to return to the SEA TRIAL menu.
After the calibration, the indicator “?” next to “COMPASS CALIBRATION” on the SEA TRIAL
menu changes to “DONE”.
Note: If the boat starts to turn automatically, the COMPASS TYPE may be wrong.
