It is recommended to calibrate the Motion Processor in the Orca Core after installing the Orca Core on your boat for the first time.

Calibration must be done at sea, as your vessel will need to do at least a 360-degree turn to calibrate its compass.

The Orca Application will automatically notify you if a calibration is needed when you connect to your Core. If you have dismissed this notification, open Main Menu > Settings > Orca Core and press Calibrate to begin calibration. After the calibration is complete, align your boat's direction with the Core's compass heading via Set compass offset.
