Garmin 9-axis Heading Sensor Installation Instructions - Page 3

5 Turn on power to the sensor, and wait until the heading data appears on the display . À 6 Within three minutes, complete two full, slow, tight circles , Á taking care to keep the boat as steady and level as possible. The boat should not list during calibration. If possible, you can turn the vessel in place by engaging two engines in opposite directions. When the sensor is prepared to calibrate the compass, the heading data disappears from the display .  You may receive an error message that the heading was lost. You can ignore this message. 7 Continue turning in the same direction at the same speed for approximately 1 1/2 rotations until the heading data à appears . Ä 10When it is safe, straighten the boat and drive in a straight line at cruising speed (must be at least 6.4 km/h (4 mph)) until Æ the heading data appears . Ç When the heading appears, the compass has been calibrated, and the heading has been aligned on the sensor. 11Test the results of the calibration, and repeat this procedure if necessary. Restoring Factory Default Settings If you relocate the sensor or do not believe the calibration was successful, you can delete all calibration information from the sensor, and restore its factory default settings. After restoring the factory default settings, you must configure the sensor before you can use it with your system. 1 Select Settings > Communications > NMEA 2000 Devices > Device List. 2 Select the name of the sensor. 3 Select Review > Factory Defaults > Yes.

Over the next two minutes the heading data should disappear and then reappear. When the heading data reappears, the compass should be calibrated and no heading offset should be applied. NOTE: If an unwanted heading offset is applied, you must disconnect all GPS sources from the NMEA 2000 network, and repeat the calibration. If the only available heading display is also a GPS source, you must repeat the calibration, and disconnect the sensor after step 7. 9 Continue turning in the same direction at the same speed for approximately ten seconds, until the heading data disappears from the display .
