• Change in the Installation Interface menu: Select FLUX =
ROBNET.
• Select FLUX as compass in the User Set-up Menu to activate
the RC25 as the steering compass.
• Perform the compass calibration as described on page 62.
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
63 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.
RFC35 Fluxgate Compass
The RFC35 Fluxgate Compass can be connected to the J50
Junction Unit, but the compass is not recommended for
commercial use.
