Operation Settings - Crunch BLACK Series Operation Manual

City Operation
In modern cities there are many weak signals which have no relation to the
traffic signal controllers. The City mode reduces the detector's sensitivity to
weak signals and eliminates responses to false sources.
It‟s important to notice that old or poorly shielded detectors in other vehicles can
sometimes transmit weak radar signals. So don‟t forget to switch on the City
mode where it is necessary.
 To select the City mode, press CITY button.
 Press CITY button again to go back Highway mode
The Highway mode provides maximum sensitivity for open road driving
where there are no false signals
Mute Operation
To silence the detector, press MUTE. You can also press MUTE button while
the audio alert is sounding to silence it. Press MUTE button again to restore
audio alarm.
Tone Operation
To change the tone sound, press MUTE for three seconds. The unit will change
the tone sound.
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 will flash in unison with the audio
tones.
When the pulses of laser light from a laser gun are detected by your
detector
a. The audible alarm will emit a distinctive sound for laser.
b. The "L" indicator will flash and start blinking.
c. Laser detection will override all radar bands.
