OPERATION
In City Mode, weak speed/safety radar signals give an initial
alarm of two beeps, and then remain quiet until the signal
becomes very strong. When the signal strength increases,
two additional beeps are provided. City 1 and City 2 Modes
operate the same as Highway Mode, but in City 1 Mode, only
the X band is lowered. In City 2 Mode, X-band is not
detected.
CAUTION: Some towns/small cities may still be using X band
radar. City Modes do not change the audio alert for laser or
VG-2.
Vehicle Battery Saver Mode
The Vehicle Battery Saver Mode automatically shuts off your
detector after 6 hours if you forget to turn it off. The timer is reset
if the detector is turned off, unplugged or any button is pressed
before the time has expired. The detector will alert you with an
audible and visual warning before it shuts off. During this warning
you can momentarily reset the unit by pressing any button. This
will reset the timer. If the unit has automatically turned itself off,
press any button to turn the unit back on.
