Compass

Your ESD-9860 includes an internal 8-point
compass that will continuously display your
current direction of travel: N, NE, E, SE, S,
SW, W, or NW.
Calibrating the Compass
Important: Before using it for the first
time, you must calibrate the compass to
provide accurate indications of direction.
(See page 7 for instructions using the
Program mode to select Set Compass.)
Calibration allows the compass electronics to
measure and store information about the
magnetic fields generated by your vehicle.

The compass will remain accurately
calibrated as long as your ESD-9860 is
mounted in the same place in your vehicle.
If you change the location where the unit is
mounted or move it to another vehicle, you
must recalibrate the compass.
The compass temporarily may not provide
accurate readings if you are inside a
building or enclosure, or are close to a
large metal tractor/trailer, truck, or train.
Once you are away from such a location,
the compass will work correctly again.
