Cobra XRS 979 Operating Instructions - Page 13

Your Detector Settings 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. If the Optional GPS Locator is installed and receiving a signal, its Compass function will override the magnetic Compass except when the GPS signal is lost. Set Compass After the detector is installed in your vehicle and Compass is turned On using Menu mode, the system will automatically advance to the Set Compass calibration screen from which the calibration can be performed. WARNING Before calibrating the Compass, go to a large parking lot or other safe, low-traffic area. When 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. From the Calibrate Compass screen: 1. Press the Mute6 button to begin compass calibration. 2. Drive your vehicle in two circles. 3. Press the Mute6 button to complete the setting process. The system will store the calibration data and provide a completion message on the display as well as a tone or voice message. Your Detector Settings NOTE If you do not press the Mute6button within two minutes after beginning the Set Compass process, Compass calibration will automatically terminate. The unit will provide a corresponding message. Once the initial calibration is complete, you can go to Set Compass in User Settings Menu and recalibrate the Compass as needed by repeating the three-step calibration process. SmartPower Mode Your detector includes the SmartPower feature that, when turned On, will put the unit into Low Power mode 15 minutes after the car's engine has been turned Off. Before SmartPower enters Low Power mode, you will hear three beeps and SmartPower will flash on the display. SmartPower Entering Standby Mode (Flashing) To return the unit to Normal Power mode and exit Low Power mode, start the car, press any button or turn the unit Off and then On again. The factory setting is SmartPower On. Speed Units If an Optional GPS Locator unit is installed, you can select between mph and km/h as the units of speed to be displayed. The factory setting is mph. Restore Factory Settings From the Restore Factory Settings screen, you can quickly and conveniently restore your detector to its original settings. Confirmation messages are provided during the process. 20 English Nothing Comes Close to a Cobra® 21
