<I'> ~~~; the instructions direct you to drive in two circles, make two complete loops in either
direction from any starting orientation at any convenient speed. The loops need not be
perfect and can be circles, small squares, four three-point turns, or any pattern that makes
at least two complete turns within two minutes of starting the maneuver.
Willi need to calibrate the compass every time I use my radar detector?
No. The compass electronics holds the information about the magnetic fields produced 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.
