Stay Alert Feature

The Stay Alert Feature is designed to test a

driver’s alertness. To engage (when the unit is

not alarming) :

• Press and hold the City button for

approximately 2 seconds. Release the button

during or immediately after the alert is given.

Display shows:  

Within 30-60 seconds, an alert is sounded; to

show alertness, the driver must press either the

City, Menu, or Quiet buttons within 3-5 seconds.

If a button is pressed within 3-5 seconds, the

cycle is repeated.

If a button is not pressed within 3-5 seconds, an

alarm sounds and the display shows: 

• Press the Dark button to exit the Stay Alert

feature.

WARNING!!! 

Stay Alert is NOT intended as a

substitute for adequate rest. You should NOT

operate a vehicle if you are drowsy. During

extended periods of vehicle operation, you

should take frequent breaks. Improper reliance

on the Stay Alert feature may result in vehicle

damage, personal injury or death. 

NEVER OPERATE A VEHICLE IF YOU ARE

DROWSY.

OPERATION

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.

POP

™ 

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 (see pg.

21).

RESET FEATURES

All user features can be reset to factory settings.

•Unplug the Power Cord from the unit.

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 the fuse in the plug; replace if 

necessary with a 2 amp, 3AG type.

• Check the fuse for lighter socket; replace if 

necessary.

• Make sure the lighter socket is clean.

PROBLEM:  Unit alarms when vehicle hits

bumps.

• Check for a loose lighter socket; tighten and 

clean.

• Check the connections at both ends of the 

power cord. Substitute another cord to 

determine if the cord is defective. Return the 

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 FAQ page at

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 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

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

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. 

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 +/- 50nm.

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 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 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.

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 radar detector

user to know and understand the laws in

your area regarding the legality of the use of

radar detectors.
