Compass calibration
This function will activate the compass
calibration procedure for Simrad compasses
connected to Robnet2 and the Autopilot
Computer terminals (HS).
Notes !
1. The RC36 Rate Compass that comes with the autopilot as
standard will store the calibration and off-set data in its own
memory.
2. Compass calibration for a second compass connected to the
HS terminal will be stored in the Autopilot Computer
memory.
3. Calibration is made on the compass that is active for the
autopilot. The active compass is the one that is displayed on
the compass calibration screen.
RATE-0 = Rate compass, FLUX-0 = Fluxgate compass on
HS terminals.
4. If an optional NMEA compass from Simrad or another
manufacturer is installed, also refer to the optional compass’
manual regarding calibration. This compass will not be
calibrated by the autopilot.
Before you start the compass calibration, make sure you have
enough open water around you to make a full turn with the boat.
The calibration should be done in calm sea conditions and with
minimal wind to obtain good results. Use about 60-90 seconds to
make a full circle.

clockwise. The display will flash “Calibrating”. Establish
your turning rate using the arrows in the display.
