• Change in the Installation Interface menu: Select FLUX =
ROBNET.
• Select FLUX as compass in the User Set-up Menu to activate
the RC25/RFC35R as the steering compass.
• Perform the compass calibration as described on page 133.
Note ! After turning on, the compass will stabilize in less than 30
seconds, but it will need another 10 minutes to fully utilize
information from the rate sensor.
Refer to Compass Offset on page 134 to compensate for any
permanent offset after the calibration is completed.
Calibration data is stored in the compass and will not be deleted
by a Master Reset in the autopilot. However, offset
compensation must be reset.
