Select the amount of
correction by turning the
course knob to offset the
heading to agree with the
known, accurate heading. The
Offset value can be either
positive or negative.
Note ! If an OFFSET still exists after having compensated for it, one of
the following problems may still exist:
• The heading reference to which you are comparing the
compass is not correct.
• The automatic calibration is not correct. Refer to above
“Compass deviation”.
Proceed to the next menu item by pressing the STBD button, or
return to Standby mode by pressing the STBY button.
Set Thrust Direction
(Only applicable if a thruster is connected)
Rotate the course knob
clockwise to activate the Set
thrust direction setting.
Rotate the course knob CW and verify that the vessel turns to
starboard. The thruster stops after 10 seconds, or when the
STBD button is pressed.
If the boat turns to port when the course knob is turned CW,
rotate the knob to port to ensure a starboard turn.
The autopilot has now been set to the correct thrust direction.
On thrusters, a change in direction command will always be
delayed 1 second to prevent thruster breakage.
