Your Detector Settings 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. N NW NE 8-Point W Compass E Calibrating the Compass SW SE S 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. 18 English Your Detector Settings Program/Mute Button Set/City Button Select/Dim Button To Calibrate the Compass Using Program Mode (See Page 7 For Instructions on Using Program Mode) In Program mode, go to Set Compass.
