After 3 seconds the audio is canceled and the
display no longer flashes. This cycle is repeated
if the VG-2 signal is detected again.
During the period a VG-2 signal is detected, a
radar signal cannot be detected. However,
because the VG-2 alert has confirmed that a
patrol car is nearby, you are already aware of the
potential for speed monitoring and can adjust
your speed accordingly. Laser detection is not
affected while a VG-2 signal is detected. (See
page 16 for more information)

SWS™
Safety Warning System™
In communities where transmitters are located,
the Safety Warning System™ displays over 60
text messages. When Safety Radar is detected,
the audio alert sounds like a geiger counter.
Safety Warning System Text Example: Poor - Road -

Note: Not all areas have Safety Warning System™
transmitters.
POP™ MODE ALERTS
POP™ Mode Alerts
Because POP™ Mode radar utilizes the same
K or Ka band frequencies, POP™ Mode Alerts will be
displayed as regular radar alerts.
LASER/RADAR ALERTS
Speed Radar Audio/Visual Alerts
When X, K, or Ka is detected, the band ID and
signal strength is displayed. The audio alert is
continuous and has a pattern like a geiger
counter. The faster the beep, the closer or
stronger the radar source.
Laser Audio/Visual Alerts
When a laser signal is detected the audio alert is
continuous for a minimum of 3 seconds.
• The Display Shows:
Pulse Protection®
Pulse (or instant-on) radar is more difficult to
detect than conventional radar because it
remains ‘off’ until activated to measure the
speed of a targeted vehicle.
When a pulse type transmission is detected, your
Whistler detector sounds an urgent 3-second
audio warning and the display shows:
After the 3-second pulse alert, the standard alert
pattern continues for as long as the signal is
present.
It is important to respond promptly to a pulse
alert, since warning time may be minimal.
VG-2 Audio/Visual Alerts
Note: You must turn this feature on before it will detect VG-2.
When a VG-2 signal is detected, the detector “hides” its
own radiated signal and becomes undetectable by the
VG-2. Every 30 seconds, the detector checks for a VG-2
signal. If a VG-2 signal is still present, the unit continues
to hide and repeats the VG-2 alert. If no signal is
detected, two beeps are provided, indicating an “all
clear” condition. During a VG-2 Alert X, K, and Ka band
signals cannot be received (see pg. 22).
ALERT PRIORITY
When two or more signals are received at the same
time, the alert priority is:
1. Laser
2. VG-2
3. Speed Radar
4. Safety Radar
Example: If X band is alerting, then suddenly a VG-2
signal is detected, the VG-2 warning will
override the X band alert.

TROUBLESHOOTING Care And Maintenance
During the summer months, avoid prolonged
exposure to direct sunlight by removing your unit
from the dash when your vehicle is parked for an
extended period of time. Do not spray water,
cleaners, or polishes directly onto the unit. The
spray may penetrate through the openings and
damage the unit. Also, do not use any abrasive
cleaners on the unit’s exterior.
ARE DETECTORS LEGAL?
In Most States YES!
Laser-Radar detectors are legal in every state
(except Virginia and Washington, D.C., which have
local regulations restricting the use of radar
receivers in any vehicle) when used in
automobiles or light trucks (under 10,000 lbs.).
The Federal Highway Administration (FHWA)
issued a regulation, effective January, 1994 which
prohibits radar and laser detector use in vehicles
over 10,000 lbs. Prior to the FHWA regulation,
laws existed in New York restricting the use of radar
detectors in trucks over 18,000 lbs. and in Illinois in
trucks over 26,000 lbs.
CARE AND MAINTENANCE FCC ID : HSXWH21
This device complies with part 15 of the FCC
Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference,
and
(2) this device must accept any interference
received, including interference that may cause
undesired operation.
Important: FCC (Federal Communications
Commission) requirements state that changes or
modifications not expressly approved by
Whistler could void the user’s authority to
operate the equipment.
SPEED MONITORING
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 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.
FCC INFORMATION
18 19 20
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. If you
can’t see past a vehicle ahead of you, chances
are your detector won’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.
SPEED MONITORING
21
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!
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:
• Pacing - A patrol car drives behind you and
matches your driving speed.
• Vascar/Aircraft - 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 19), 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.
SPEED MONITORING Note: Having a radar detector capable of
detecting the VG-2 may alert you to the
presence of a speed trap.
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
owner to know and understand the laws in your area
regarding the legality of the use of radar detectors.
