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 Mute
6
button to begin compass calibration.
2. Drive your vehicle in two circles.
3. Press the Mute
6
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.
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.
NOTE
If you do not press the Mute
6 button 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.
