Calibration Procedure A: Ahrs Orientation - Garmin G3X Installation Manual

The addition, removal, or modification of components that are ferrous, or otherwise magnetic, within 10.0
feet of the GMU 22 magnetometer location after the magnetometer interference test or magnetometer
calibration procedure were completed requires a repeat of both procedures.
Furthermore, electrical changes to the installation that affect components within 10.0 feet of the GMU 22
magnetometer after the magnetometer calibration and magnetometer interference procedures were
completed will require a repeat of the magnetometer interference test. If new magnetic interference is
detected, it must be resolved and then the magnetometer calibration procedure must be repeated. Wiring or
grounding changes associated with a device located in the vicinity of the GMU 22 is a good example of
such a change.
