6.1 HOW THE RADAR WORKS
The actual process involved in determining a vehicle's speed is basically a simple one. It involves directing a beam of microwave energy
at an approaching target vehicle. A portion of this beam is reflected by the target and is received by the radar unit that originally
transmitted the signal. The reflected signal is shifted in frequency by an amount proportional to the speed of the target vehicle.
This phenomenon is known as the Doppler effect. The radar unit determines the target vehicle speed from the difference in
frequency between the reflected signal and original signal.
To activate the Radar Detector, please read chapter 4.2.9 'SN 0 Display'. To de-activate the Radar Detector press the red button
briefly (not longer than 2 sec.!). If you press this button too long, the device will set to 'illumination' mode and the Radar Detector
will NOT be switched off.
6.2 RADAR FREQUENCIES
The QUINTEZZ DRIVE CONTROL can detect 5 radar bands with 14 different frequencies and includes Instant ON radar and POP
radar.
X band: 9.41 Ghz, 9.9 Ghz, 10.5 Ghz, 10.525 Ghz, 10.6 Ghz 9.9 Ghz, 10.5 Ghz, 10.525 Ghz, 10.6 Ghz
Ku band: 13.450 Ghz,
K band: 24.1 Ghz, 24.125, 24.15 Ghz 24.1 Ghz, 24.125, 24.15 Ghz
Ka narrow-band: 34.0 Ghz, 34.3 Ghz, 34.36 Ghz
Ka wide-band: 34.7 Ghz, 35.5 Ghz
POP detection
6.3 LASER DETECTION
Laser detection is another kind of signal that can be detected. Laser Speed Guns use pulses of infrared laser light to measure speed
of target by timing each pulses over time as it is reflected back to the gun.
6.4 LASER RANGE
The effective range of clocking distance by a laser gun is less than 1 km. The operator of the laser gun is instructed to target on the
number plate. So, mount your laser detector as low as possible in the car. The QUINTEZZ DRIVE CONTROL offers the possibility to
detect a laser from front as well as from behind.
If the Laser Detector is activated by reflection signals from the laser beam to a vehicle in front of you, then you still have time to
react on the laser check.
If the Laser Detector is activated by a laser beam that is pointed on your car, then your speed is already measured during the laser alarm.
6.5 OTHER SPEED CHECKS
There are a couple of other checks that cannot be detected by Radar or Laser Detectors. These checks include digital video recording,
loops within the road and optical speed checks. These checks have to be detected by GPS.
A Radar Detector is able to detect several of these traps, but not all of them. The new generation of radar speed traps is increasingly
difficult to detect by means of a Radar Detector. Furthermore, the Radar Detector is forbidden in many countries. False alarms occur
on a regular basis with each and every Radar Detector.
