UNDERSTANDING YOUR INSTRUMENT PANEL 93
When the CAL indicator goes off, the compass is cali-
brated 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
4
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 vari-
ance 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.
