UNDERSTANDING YOUR INSTRUMENT PANEL 93 When the CAL indicator goes off, the compass is calibrated and should display correct headings. Verify proper calibration by checking North (N), South (S), East (E), and West (W). If the compass does not appear accurate, repeat the calibration procedure in another area. Compass Variance Variance is the difference between magnetic North and geographic North. For proper compass function, the correct variance zone must be set. Setting the Compass Variance Refer to the variance map for the correct compass variance zone. To check the variance zone, the ignition must be on and the compass / temperature displayed. Hold down both the US / M and STEP buttons simultaneously until the VAR symbol is lit and then immediately release both buttons. The current variance zone will now be displayed. To change the zone, press the STEP button until the correct zone is displayed. Wait for about 5 seconds. The trip computer will store this variance in memory and the compass will resume normal operation. 4
