HOW THE RADAR AND LASER WORK-GENERAL
A. 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.
B. RADAR & LASER FREQUENCIES
The QUINTEZZ XT-9500 can detect 12 radar bands:
X-Band 10.50 GHz X-Band 10.525 GHz
X-Band 10.600 GHz Ku-Band 13.450 GHz
K-Band 24.125 GHz K-Band 24.150 GHz
K-Band 24.220 GHz Ka-Band 34.70 GHz
Ka-Band 35.50 GHz
Ka-Band Wide+Narrow 34.00 GHz
Ka-Band Wide+Narrow 34.30 GHz
Ka-Band Wide+Narrow 34.36 GHz
C. LASER DETECTION
Laserdetection is the 13th band that can be
detected. Laser Speed Guns use pulses of infrared
laser light to measure speed of target by timing each
pulse over time as it is reflected back to the gun.
D. LASER RANGE
The effective range of clocking distance by a laser
gun is less than 1Km. So, mount your laser detector
as low as possible in the car.
The QUINTEZZ XT-9500 offers the possibility to
detect a laser from before as well as from behind.
OPERATION
A. SELF TEST
Press the ON/OFF key (PWR) to switch the unit
ON. If the unit is switched ON, it will immediately
perform a self-test. During the test the different
steps will be shown in the display and the different
tones will be activated. If the test is finished and
the different settings were shown, the P (Power)
will light. Press the ON/OFF key (PWR) again to
switch the unit OFF.
