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.
