So don't forget to switch on the City mode where it is
necessary.
•
To select the city mode, press CITY button. A yellow
LED "C" will blink.

Mute Operation

To temporarily silence the detector, press MUTE.
After leaving the area of the transmission source, the
detector automatically returns to normal after 20 seconds.
You can also press MUTE button while the audio alert is
sounding to silence it.

Receiving and Identifying Radar and Laser Signals

When your detector identifies radar signals, the following
will occur:
1. Distinctive audible alarms will be emitted for X-, K-, and
Ka-band radar signals.
The alarm sounds will occur faster and faster as the signal
gets stronger (as you get closer to the source).
When the signal gets very strong, the alarm sounds
become continuous tones.
2. The appropriate visual alarm indicator for X/K/Ka-bands
will flash in unison with the audio tones.
