Compass Calibration Set-Up (1748 only)
The unit will need to be calibrated in order for the
compass to provide accurate readings. To calibrate the
unit, perform the following procedure:
1. Mount the unit level in the center of the vehicle’s
windshield in which it will be used. Make sure there are
no other magnetic sources near the detector (i.e.,
speaker).
2. Select a large clear area (parking lot or field)
without any power lines.
3. While parked, press both volume buttons
simultaneously until the compass headings start to
rotate.
4. Drive vehicle slowly in two complete circles, in either
direction. If calibration does not automatically finish
press both volume buttons simultaneously to complete
calibration. The unit will beep twice and show current
compass heading.
Note:
If unit mounting is relocated in the vehicle, (i.e.
visor to windshield mounting or dash mounting), or if
the unit is moved to another vehicle, you must recali-
brate the compass.
