Compass Calibration (Uplevel Only) The compass can be manually calibrated. To calibrate the compass through the DIC, see DIC Compass (Uplevel Only) on page 240. Compass Calibration Under certain circumstances, such as during a long distance cross-country trip, it will be necessary to compensate for compass variance and reset the zone through the DIC. Compass variance is the difference between the earth's magnetic north and true geographic north. If not adjusted to account for compass variance, the compass in the vehicle could give false readings. In order to do this, the compass must be set or calibrated to the variance zone in which the vehicle is traveling.
