Setting Magnetic Zone Variance
Variance is the difference between magnetic North and geographic North. For proper compass function, the correct variance zone must be set. Refer to Fig 1 for the correct zone.
Follow these steps to check or change the variance zone:
- The ignition switch must be in the ON position and the Compass/Temperature Module display must not be blank.
- Depress and hold the STEP button for 5 - 10 seconds until ZONE appears in the display, then release the STEP button. The number displayed is the variance zone currently stored in the compass memory.
- To change the zone, depress the STEP button to scroll through the zone numbers 1 through 15, until the desired zone is displayed.
- After selecting the zone, wait approximately 15 seconds until the display returns to normal.
