Compass Variance
Variance is the difference between magnetic north and
geographic north.
In some areas, the difference between
the two can
be great enough to cause false compass
readings.
If this happens, follow these instructions
to set the variance for your particular location:
--
1. Find your location on the zone map. Note the
zone number.
2. Hold in the CAL switch (on the bottom of the mirror
housing) for five seconds
until the current zone entry
number appears in the display.
To hold in the CAL
switch, insert a paper clip into the small hole on the
bottom
of the mirror housing.
3. Press the CAL switch until the number for the new
zone entry
is displayed.
Once the desired zone number is displayed, stop
pressing the
CAL switch and the display will show
compass direction within a few seconds.
