Mode Alerts

Because POP

™

Mode radar utilizes the same

K or Ka band frequencies, POP

™

Mode Alerts will be

displayed as regular radar alerts.

Speed Radar Audio/Visual Alerts

When X, K or Ka is detected, the band ID and
signal strength are displayed. The audio alert is
continuous and has a geiger counter-like 
pattern. 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 Displays 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.

Alert Priority

When two or more signals are received at the
same time, the alert priority is:
1. Laser  2. Speed Radar  3. Safety Radar
Example: If X band is alerting, then suddenly a
laser signal is detected, the laser warning will 
override the X band alert.

Compass Calibration Set-up 

The unit will need to be calibrated in order for
the compass to provide accurate readings.  To
calibrate the unit, perform the following
procedure:
1

1.. Mount the unit level in the center of the 
vehicle’s windshield. Make sure there are no
other magnetic sources near the detector 
(i.e., speaker).
2

2. Select a large clear area (parking lot or field)
without any power lines.
3

3. Press the Menu button until display shows 
C

CA

AL

L M

4. If calibration does not automatically finish press
the Dark and Quiet buttons simultaneously to
complete calibration. The unit will beep twice and
display shows, for example:

Note: In Combo Mode an “H

H” or “C

C” will be

shown to indicate mode of operation. 
Important: If unit mounting is relocated in the
vehicle, (i.e., visor to windshield mounting or
dash mounting), or if the unit is moved to
another vehicle, you must recalibrate the
compass.

Your Whistler detector is expertly engineered
and designed to exacting quality standards to
provide you with reliable, trouble-free operation.
If your unit has been correctly installed following
the guidelines in this manual, but is not 
operating optimally, please refer to the 
troubleshooting guide below.

PROBLEM:  No display or audio.
• Check fuse in plug; replace if necessary with a

2 amp, 3AG type.

• Check fuse for lighter socket; replace if 

necessary.

• Make sure lighter socket is clean.

PROBLEM:  Unit alarms when vehicle hits
bumps.
• Check for loose lighter socket; tighten and 

clean.

• Check connections at both ends of power 

cord. Substitute another cord to determine if 
cord is defective. Return defective cord to 
the factory.

PROBLEM:  Audio alerts are not loud
enough.
• Cancel Auto Quiet Mode or City Mode.
• Check audio level setting (see page 8 ).
If difficulties occur which cannot be solved by 
information in this Troubleshooting Guide, please
call Whistler Customer Service at 1-800-531-0004
or visit our F.A.Q. page at
www.whistlergroup.com/faq-detectors.asp,
before returning your unit for service.

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.

In Most States YES!

Laser-Radar detectors are legal in every state
(with the exception of 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.). 
Concerning trucks over 10,000 lbs., the Federal
Highway Administration (FHWA) issued a 
regulation, effective January, 1994 which prohibits
radar and laser detector use in these types of
vehicles nationally. Prior to the FHWA regulation,
laws existed in the state of New York restricting
the use of radar detectors in trucks over 18,000
lbs. and in Illinois in trucks over 26,000 lbs.

FCC ID: HSXWH20

This device complies with part 15 of the FCC
Rules. Operation is subject to the following two
conditions:  
(1) This device many not cause harmful 
interference, and
(2) this device must accept any interference
received, including interference that may cause
undesired operation.

Important:

FCC requirements state that

changes or modifications not expressly approved
by Whistler could void the user’s authority to
operate the equipment.

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.

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!

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

afftt - The time it takes a vehicle to 

travel a known distance is measured.

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 18), 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.
