Manual Calibration

With the ignition in the ON position, pressing and holding the Zone/Cal button (left reading lamp button) for 10-15 seconds will toggle the display to CAL. Releasing the button within the 10-15 second duration will enter the compass into the calibration mode. CAL will remain illuminated until the calibration is complete or is toggled off by pressing the Zone/Cal button. Move the vehicle to an area away from large metallic objects or overhead power lines. While CAL is illuminated in the display the vehicle must be driven in 3 complete 360 degree circles at less than 5 MPH (8 KPH). The compass will calibrate; CAL will turn off, and then resume normal operation.
