Heading sensor calibration
The built in heading sensor will need to be calibrated before use
to compensate for local magnetic fields on your vessel for accurate
chart with radar overlay.
Auto Calibrate mode
Before the heading sensor calibration is started, make sure that
there is enough open water around for the vessel to make multiple
full turns. The calibration should be done in calm sea conditions
and with minimal wind to obtain best results.
A Disconnect then re-connect the sensors NMEA 2000 cable.
B Make two consecutive turns of 360 degrees. The completion
of these two turns automatically activates the Auto Calibration
procedure.
C Continue with a smooth third turn and a quarter (of at least 390
degrees) within 2 to 5 minutes, to complete the calibration.
D Calibration should be complete. If the time is outside the limits,
the calibration is void and the radar overlay may not appear
accurate on your chart. Repeat steps A-D again.

Calibration from a Multifunction Display
Calibration can be performed from a compatible Multifunction
Display, instrument display or autopilot controller. (Please refer to
the operator/installation manual).
Multiple heading sensors on the network
WARNING:
If there are two Point-1 units (or an additional heading sensor) on
the network, the Point-1 antenna(s) will stop sending heading
information.
This does not apply to Simrad GS25 and B&G ZG100.
Heading sensor application
This sensor includes an electronic heading sensor to provide chart
stabilization, course over ground at low speeds, and overlay of radar
on charts.
Acceptable performance for the application
A rate stabilized heading sensor such as RC42N
will provide the most robust performance for
demanding applications.
