Setting Saver

Setting Saver stores your personalized settings

so that when the detector is turned off and then

on again, you do not have to re-enter them.

VG-2 Mode

See Option Select Mode to turn this feature on/

off. When a VG-2 signal is detected, the VG-2

alert is sounded and the display flashes “VG-2”.

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 24 for more information)

Laser Signature ID (LSID)

Identify the Laser gun’s pulse rate or PPS (Pulses

per Second) that is transmitted by the speed laser

gun. LSID may also be used to identify other forms

of laser sources such as LACC (Laser Assisted

Cruise Control) systems found in some high end

vehicles. If the Laser PPS information displayed

is due to another source such as local airports or

LACC, LSID allows you to Lock Out this rate from

giving you the continuous audio alert during this

and any new encounter of the same rate.

To lock out a PPS, press the Quiet button during

the Laser alert. This will place an * on the screen

beside the PPS rate and Lock Out this signature

ID. Any new encounter with the same Laser

Signature ID will provide the display information

and two quick beeps.

Caution: Do not lock out a PPS rate if it is close

to known speed laser guns.

Segmented Selectable Laser Receiver

If these alerts are bothersome, you may wish to make

note of the PPS rate for these occurrences. The laser

validation windows are separated into segments allowing

for customization.

Segment Pulse Rate

Laser Area 1: 20Hz to 950Hz

Laser Area 2: 2600Hz to 3200Hz

Laser Area 3: 3800Hz to 4200Hz

Laser Area 1 covers the traditional laser guns used in North

America. Laser Area 2 and 3 cover laser guns recently

approved for use in North America. You can change the

selection from yes to no individually in option mode.

If laser within a group is not used in your area, you may shut off

that group (change the selection from Y to N while in Option

Select Mode) by pressing the DARK or QUIET buttons.

POP

Mode Alerts

Because POP

Mode radar utilizes the same K or Ka

band frequencies, POP

Mode Alerts will initially be

displayed as POP K or POP Ka then switch to band and

signal strength.

Safety Warning System

In communities where transmitters are located, the Safety

Warning System

provides over 60 text messages. When

SWS

is detected the audio alert is geiger counter-like.

Safety Warning System Text Message

Example: Poor - Road - Surface.

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

Example: If X band is alerting, then suddenly a laser signal is

detected, the laser warning will override the X band alert.

Option Select Mode

Press the Menu button to enter Option Select Mode. Press the

Menu button again will step thru in an ascending order while

pressing the City button will step thru in a decending order.

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, two beeps are 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.

Display shows:

• Press the DARK button to exit during 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.

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 word “LSR” and

the corresponding laser pulse rate is displayed, the

audio alert is continuous for a minimum of 3 seconds.

“LSR 238”

Pulse Protection

®

Pulse (or instant-on) radar is more of a threat 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.

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.

TROUBLESHOOTING

Your Whistler detector is expertly engineered and

designed to exacting quality standards to provide you

with reliable, trouble-free operation. If your unit has

SPEED MONITORING

SPEED MONITORING WARRANTY INFORMATION WARRANTY INFORMATION WARRANTY/SPECIFICATIONS

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, 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

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.

FCC Information

FCC ID: HSXWH10

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,

(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.

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.

SPEED MONITORING

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 wave length of 905nm

+/- 50nm including but not limited to the following:

• Ultra Lyte

• LTI 20-20

• LTI TruSpeed

®

S

• Laser Ally

• Pro Laser

I II III

• Laser Atlanta

®

Stealth Mode

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.

This laser/radar detector receives signals from 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: Your radar detector is designed to alarm if an officer

is transmitting on any one of the above radar bands.

FAQs

How good is Whistler radar detector? ›

Whistler does not make the best radar detectors. But they do make by far and away the best cheap radar detectors, and they are useful , good, reliable, and attractive units that can be plugged in and go right to work sniffing out police radar. They are not "cop car detectors".

What does P mean on a Whistler radar detector? ›

P is for pop detection.

What does V mean on Whistler radar detector? ›

Quiet/VOL Button - Pressing QUIETbefore a signal is detected engages Auto Quiet Mode. Pressing QUIET during a radar/laser encounter silences audio alerts.

What mode should my radar detector be on? ›

Highway mode is the most sensitive level while City mode is the least sensitive. If the X band is left on in City mode, a radar detector can pick up many X band signals (such as garage door openers) that generate false alerts.

Why does my radar detector go off for no reason? ›

These false alarms come from moving vehicles with advanced safety systems. Some examples of these systems include auto-pilot, radar cruise control, adaptive cruise control and blind spot monitoring systems. These systems emit K band radar signals which will confuse the radar detector.
