Each time a button is pressed, one beep confirms feature “on”, two beeps confirm feature “off”.

Audio Level Adjustment

The audio levels can be adjusted high to low or low to high.

• Press and hold the “VOL” button and the volume level will increase (Level “IIIIII”) then proceed to lower the volume (Level 0).

Continuing to hold this button will repeat the sequence. As audio level is adjusted, beeps are provided and the display indicates volume level.

OPERATION

Quiet Mode

Quiet cancels audio during an alert and any new alert within 20 seconds. After 20 seconds, approximately 2 beeps are provided on any new alert and unit then remains quiet.

• Press Quiet to cancel the audio.

• To restore the standard audio alert pattern, press Quiet a second time during an alert or tun the unit off, then on.

Auto Quiet Mode

Auto Quiet reduces the selected audio level to level (1) approximately 5 seconds after a radar or safety radar signal is detected. The alert for any new signal within 20 seconds will resume at level

(1). Auto Quiet does not affect VG-2 or laser alerts.

• Press Quiet/Menu (before a signal is detected) to engage Auto Quiet.

• Once the Auto Quiet mode is engaged, you may cancel the audio alarm by pressing Quiet.

• Press Quiet (when the unit is not alarming) to cancel Auto Quiet mode.

Low Profile Alert Periscopes

Whistler’s Low Profile Alert Periscopes provide an added attention getting visual alert. The two extra

LED’s flash on and off when the unit alarms to provide a unique visual alert. This alert can be programmed through the Option Select Mode to be: ON, OFF, or FLASHING during alerts.

OPERATION

City/City I/City II Mode

Whistler’s Three Stage City Mode is designed to reduce the annoyance of automatic door openers, intrusion alarms and other devices which share frequencies with police radar.

Generally, X band is used for these devices.

• Press City to cancel Highway mode and engage City mode.

Display will switch from “H

• Press City again to enter City II Mode

• Press City again to enter City IIII Mode

N otte indicator turns off.

• Press City a fourth time to cancel City IIII Mode and return the unit to Highway Mode.

In City Mode, weak speed/safety radar signals give an initial alarm of two beeps, and then remains quiet unless the signal becomes very strong. When the signal strength increases, two additional beeps are provided. City 1 and City 2

Modes operate the same as Highway Mode, but in City 1 Mode, X band requires a stronger signal to alert. In City 2 Mode, X-band is not detected.

Caution: Some towns/small cities may still be using X band radar. City Modes do not change the audio alert for laser or VG-2.

OPERATION

Teach/Tutorial Mode

Provides simulated alerts for each type of signal.

• Press City and Quiet simultaneously and release.

• Unit will go thru all the bands detected.

• Press Power to exit.

Dim/Dark Mode

Dim/Dark Mode reduces the illumination of the display

• Press and release the Dark button to reduce illumination to a dim setting.

• Press and release the Dark button a second time to engage Dark Mode. The display illumination is further reduced.

Dim or Dark can be engaged during an alert. In

Dark Mode, the display goes dark for as long as a signal is being detected and 20 seconds after, then the display returns to the dimmer setting.

• Press and release the Dark button a third time to restore the display to full illumination.

VG-2 Detection

When a VG-2 signal is detected, the VG-2 alert is sounded for 3 seconds and the display flashes the “V L” icon for 30 seconds.This cycle is repeated if the VG-2 signal is again detected.

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.

OPERATION

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).

See “Menu Mode” for engaging/disengaging VG-2.

Auto Shut Off Mode

Auto Shut Off Mode automatically shuts off the detector.

The timer is reset:

3.. Any button is pressed before the timer has expired.

The detector will alert you with an audible and visual warning before it shuts off. This auto off function can be programmed for the following:

Off, 1, 2, or 3 hours. During this warning you can reset the timer by pressing any button. If the unit has automatically turned itself off, press the Power button to turn the unit back on.

VEHICLE IF YOU ARE DROWSY.

Safety Warning System

™

In communities where Safety Warning System™ transmitters are located, the detector will receive over 60 messages. When Safety Radar is detected, the audio alert is given and the display alternately flashes the “I”, “III” and “II” icons.

Note: Not all areas have Safety Warning System ™ transmitters.

LASER/RADAR ALERTS

Speed Radar Audio/Visual Alerts

When X, K, or Ka band 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.

“II” = weak signal, “IIIIII” = strong signal

K//K Ka

Laser Audio/Visual Alerts

When a laser signal is detected, the “V be illuminated.

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, your

Whistler detector sounds an urgent 3-second audio warning and the display will show a max signal strength level.

M axx S all

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

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.

POP

CARE AND MAINTENANCE

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 this unit will not be used for an extended period of time. Damage caused by leaky or improperly charged batteries are not covered under warranty. Check with the battery manufacturer about the specific battery 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.

FCC INFORMATION

FCC ID : HSXWH15

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.

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 (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 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.

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. 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

+/- 10nm.

•Pro Laser ™ I II III •LT1 20-20 •Ultra Lyte

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:

• P acciin g - A patrol car drives behind you and matches your driving speed.

Va 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.
