Control Compass Mode
The Control Compass function allows you to turn autocalibration
on/off, read the calibration score, and clear the calibration.

Selecting Autocalibration
Every antenna’s internal sensor module is calibrated at the
factory in a perfect-world environment. However, hard and soft
iron effects on your vessel can distort the local magnetic field,
causing errors in the reported heading. These errors are
minimized by mounting the antenna in a suitable location and
are further removed by the system’s autocalibration feature,
which compensates for minor magnetic distortions while your
vessel is moving. The more the vessel moves with autocalibration
turned on, the more accurate the sensor will become.
The factory default setting for Autocalibration is ON.

A well-calibrated sensor is crucial
to system performance. If you shift,
remove, or add equipment near the
antenna, KVH suggests keeping
autocalibration ON so that the
sensor will automatically recalibrate
itself.
If the antenna’s internal sensor is
not working, the following screen
will appear:
