Will I need to calibrate the compass every time I use my radar detector?

No. The compass electronics holds the information about the magnetic fields made by your vehicle.

However, for best results, you should mount the detector in exactly the same location every time you

use it. When you remove the detector from your windshield, it is best to leave the mounting bracket on

your windshield so that when you replace the detector it is mounted, again, in exactly the same place.

If you decide to relocate your detector to a different place (either on the windshield or on the dash),

it is best to calibrate the compass again.

My compass sometimes seems to give a wrong direction – what is wrong?

If your compass is unable to detect the magnetic field of the Earth (used to determine the direction),

it cannot give the correct reading. This may happen if you are under a bridge, inside a parking garage,

or inside any enclosure or building that is constructed with metal framework. Other vehicles with a lot

of metal may also confuse your compass so that it cannot give accurate readings. This may happen if

you are next to a large tractor trailer, truck or train. Your compass will work again correctly as soon

as you get away from these locations. There is no need to calibrate your compass again after this.

Calibrating Your Compass

The compass in your radar detector must be calibrated before you use it to give accurate directions.

In order to determine the direction, the compass detects the weak magnetic field of the Earth, but all

vehicles also produce many different magnetic fields that will confuse the compass.

These magnetic fields are produced by audio speakers and other electronics within your vehicle.

Calibration allows the compass electronics to measure and store information about the magnetic

fields from your vehicle so that it can then ignore them!

* Drive your vehicle in two complete circles. A large parking lot is the most convenient place to do this. Please be careful

when making the circles and watch for other traffic. 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).
