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 are 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 (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, the 

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.

MODE ALERTS

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 (Reference page 21 for VG-2 information).

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

.  SWS

Example:

If X band is alerting, then suddenly a VG-2 

signal is detected, the VG-2 warning will 

override the X band alert.

TFSR - Traffic Flow Signal Rejection

When turned on in option mode, helps 

eliminate excessive alerts from erroneous X 

and K-band sources. Traffic flow monitoring 

systems are getting more common. Many 

of these systems generate radar signals to 

measure the flow of traffic across multiple lanes. 

Most detectors will alert you to it unnecessarily. 

This rejection feature examines the incoming 

signal and will aid in reducing the alerts to such 

sources.

We suggest you turn TFSR on if you are 

experiencing excessive X or K band false alerts 

every half mile or so along stretches of roadway 

that contain these traffic flow sensors.

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.
As with all battery operated devices remove the 

batteries when the unit will not be used for an 

extended period of time. Damage caused by 

leaky or improperly charged batteries are not 

covered under warranty. 

ARE DETECTORS LEGAL?

In Most States YES!

Laser-Radar detectors are legal in every state for 

automobiles and light trucks (under 10,000 lbs.) 

except Virginia and Washington, D.C., which 

have local regulations restricting the use of 

radar receivers in any vehicle. 

The Federal Highway Administration (FHWA) 

passed a nationwide regulation, effective 

January 1994, which prohibited radar and laser 

detector use in vehicles over 10,000 lbs.

CARE AND MAINTENANCE

FCC ID : HSXWH15

This device complies with part 15 of the FCC 

Rules. Operation is subject to the following two

 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 not alarm if an 

officer is not transmitting on any one of the 

above radar bands.

POP™ Mode

POP

 Mode is a feature on some 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. 

FCC INFORMATION

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 laser signals will  

    not be the same as radar signals. 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 

± 50 nm., including Laser Atlanta ’s™ Stealth mode.

SPEED MONITORING

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 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 potentially for speeding, 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. As of this printing. Spectre can detect 

the majority of undetectable (VG-2) laser/radar 

detectors on the market.
It is the responsibility of the radar detector user 

to know and understand the laws in your area 

regarding the legality of the use of radar detectors.
