Complete at least one full 360 degree circle while the flashing "CAL" is displayed. After approximately 10 seconds the flashing "CAL" will disappear and the cardinal points and the numeric digits will stop flashing. The calibration of the compass is now completed. Check that the compass is providing readings that appear to be correct.
For best results mount the outside sensor probe either under the front bumper or in the front door frame 2 inches under the hinge. Mount the inside unit away from electronics, such as speakers, and out of the sun.
