Whistler Laser XTR-690SE - Manual (Page 8)

POP™ Mode
POP ™ Mode is a feature on some newer radar
guns operating on K and Ka bands. When the gun
is in POP
™ Mode and activated, a brief burst of
energy, less that 1/15 of a second, is transmitted
and the vehicle’s speed is quickly acquired. A
detector without POP
™ Mode detection capability
cannot respond to this brief transmission.
Laser Facts
It’s well documented that many radar guns
cannot reliably provide the speed of a targeted
vehicle that is traveling in a group of vehicles. In
contrast, a laser gun can target a specific vehicle
out of a line of traffic and determine its speed. The
advantage of laser over radar in terms of
target identification is the result of the laser gun’s
narrow beam. A radar gun’s transmission can
cover more than a four-lane highway at a distance
of 1,000 feet, compared with a laser gun’s
transmission which covers about 3 feet at the
same distance. For best protection, keep these
points in mind:
• Because the vehicle’s license plate or
headlights are the laser gun’s primary targets,
mounting the Whistler detector on the
dashboard can improve laser detection at short
range.
• Do not follow closely behind any vehicle you
cannot see through. If you can’t see past a
vehicle ahead of you, chances are your detector
can’t either.
• The receiving range of your laser detector will
not be the same as a radar detector. Laser guns
are most often used at short range.
Whistler Laser-Radar detectors receive all current
laser guns which operate at a laser wavelength of 905
+/- 10nm.

Laser Tips
If you are the targeted vehicle, a laser gun can
often determine your speed within a few
seconds after you receive an alert. In this
situation, there is generally no time to safely
adjust your speed. However, if you are traveling
near or behind the targeted vehicle and receive
an alert, response time should be sufficient. Any
laser alert, regardless of duration, requires
immediate action.
Radar Facts
A radar gun operates by transmitting radio
waves at certain frequencies which reflect off
objects and are picked up by the radar gun’s
receiving section. When a radar beam reflects
off a moving target, a measurable frequency shift
occurs. The radar unit converts this shift into miles
per hour to determine your vehicle’s speed.
Currently, the FCC (Federal Communications
Commission) permits operation of traffic radar
guns at X Band (10.500 - 10.550 GHz), K Band
(24.050 - 24.250 GHz), and Ka Band (33.400 -
36.000 GHz).
Note: A radar detector will only alarm if an
officer is transmitting on any one of the above
radar bands.
Other Speed Detection Systems
Several techniques other than radar or laser are
used to measure vehicle speeds. When these
methods are being used, no detector can provide
a warning. These techniques include:
• P
Pa acciin ng g - A patrol car drives behind you and
matches your driving speed.
• V Va asscca arr//A Aiirrccrra afftt - The police measure the time it
takes your vehicle to travel a known distance.

Radar Detector Detectors: VG-2,
Spectre
The Interceptor VG-2 or simply VG-2, is one type of
microwave receiver used by Police to detect signals
radiated by the local oscillator of a radar detector.
Because its purpose is to identify persons driving with
radar detectors, these devices are known as a “radar
detector detector” (RDD).
An RDD is the primary tool used by the police to identify
radar detector equipped vehicles. If caught in a state or
country where detectors are illegal (see page 20), drivers
risk losing their radar detector and receiving a fine. In
addition, instant-on radar is almost always used in
combination with an RDD, leaving unsuspecting
motorists vulnerable to receive two tickets; one potential
for speeding, and the other for possession of a detector.
Note: The newest tool Police have to detect radar
detectors is called Spectre. Spectre can detect the
majority of undetectable (VG-2) laser/radar detectors
on the market.
It is the responsibility of the individual radar detector
user to know and understand the laws in your area
regarding the legality of the use of radar detectors.
