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
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. | |
