Compass
Your detector 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
NOTE
Before using it for the first time, you must calibrate the compass to
provide accurate indications of direction. See page 7 for instructions
on 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 detector 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.
NOTE
When the instructions direct you to drive in two circles, a large parking
lot is the most convenient place to do so. It does not matter what
direction your vehicle is pointing when you start the circles, which
direction you go to make the circles, and it does not have to be exactly
two circles. You do NOT have to make perfect circles. You can drive in
any pattern, as long as you make two complete turns. Four three-point
turns, two small squares, or any two complete loops will work as well as
two circles. It does not matter what size the circles are, if your speed is
constant, or how fast you make the circles [but less than two minutes].
Please be careful when making the circles and watch for other traffic.
