You can easily view your current heading at a glance. There
are eight cardinal points on the display — north, northeast,
east, southeast, south, southwest, west, northwest.
Calibration helps the compass better separate the earth’s
magnetic field from the magnetic field generated by external
influences (such as your vehicle), providing more accurate
heading information.
Calibrate the compass anytime you move it, or whenever
distortion continuously appears. Before calibration, peel off
the backing on one side of the supplied tape and attach the
tape to the back of the compass, then mount the compass
by peeling off the backing on the other side of the tape, then
press the compass onto the level mounting surface, with the
compass’ arrow facing up and pointing to the front. Do not
mount the compass upside down.
1. Hold down

for a second. All eight cardinal points

2. Drive your vehicle in two complete circles. Be sure your
vehicle is on level ground, in an open area, such as a
parking lot.
3. Press
CAL
to confirm calibration
You must complete the circles on level ground and press
CAL
within 10 minutes. Or, start from Step 1 again.
