are connected to a Simrad autopilot.
Before you begin the compass calibration procedure, make sure
you have enough open water around you to make a full
clockwise turn. Let the boat turn at idle engine speed.

2.
Press the
button and hold for 2 seconds. The LCD flashes
‘rUN’ and then ‘CAL.C’.

approximately 1 ¼ turns), it will be confirmed by the display
reading ‘doNE’.

HEADING OFFSET [OFFS]
Note !
Do not use the Heading Offset procedure when the system is
connected to a Simrad autopilot.
The Heading Offset feature allows you to correct for a
permanent heading offset that may be present as a result of the
compass being installed with a lubber line offset, or a fixed
offset remains after the calibration procedure has been
completed. The value of heading offset is specific to the heading
sensor that is connected at the time the offset is entered.
1.
Activate the Heading Offset by pressing and holding the
button for 2 seconds. The reading starts flashing.
2.
Increase the compass reading using the
button or
decrease the compass reading using the
button.
3.
Save the offset by pressing and holding the
button.
