Mounting Guidelines

  • Mount the unit as low as possible near the center of the windshield.
  • Do not mount the unit behind wipers, ornaments, mirrored sunscreens, etc. These obstructions have metal surfaces
    that can affect radar and laser signals and reduce critical warning time. (Regular tinted glass does not affect reception).
  • Some windshields have an Instaclear™ or Electriclear™ type coating, which affects radar signals. Consult your dealer or the owner’s manual supplied with your vehicle to determine if your windshield has this coating.
  • Avoid placing the unit in direct contact with the windshield.
  • To reduce the possibility of theft, conceal the unit when not in use.


IMPORTANT: Make sure the unit is level Windshield Mounting

  • Install the two suction cups and rubber bumper onto the bracket by fitting them into their holes.
  • Press the suction cups onto the windshield at the location you have chosen.


Important: Some newer cars have a plastic safety coating on the inside of the windshield. The windshield bracket may leave permanent marks on this type of surface. To find out if your vehicle has this type of windshield, check the vehicle’s owner’s manual or ask your dealer. We recommend that you do not leave the suction cup bracket on the window in direct sunlight. If the detector is removed, this may cause blistering of the dash in some vehicles.

  • Slide the detector onto the bracket until it locks into place.
  • If necessary, the unit may be leveled by bending the windshield bracket. Press the bracket release button and remove the detector before bending.

Power Cord Connection

  • Plug the small end of the power cord into the unit’s power jack.
  • Plug the large end into the vehicle’s cigarette lighter socket.

NOTE: The cord fits tightly into the detector. When installing the cord, expect some resistance.

The USB can charge an iPad, iPhone, smartphone, MP3, or tablet. The output for the USB port is 1A.


Fuse Replacement

The lighter socket plug is equipped with a replaceable 3 amp, 3AG fuse located behind the silver tip. To replace the fuse, carefully unscrew the tip of the plug.


IMPORTANT: Unscrew slowly. The tip contains a spring that may fly out when disassembling. Insert the new fuse
with the spring and screw on the tip. With use, the screw cap on the plug may loosen. Retighten it occasionally.

Power On Self-Test

The 2.5mm external stereo audio jack can be used to connect an external speaker or headphones in environments with high ambient noise levels. The internal speaker will be disabled.

City/City 1/City 2 Mode

Whistler’s Three Stage City Mode is designed to reduce the annoyance of automatic door openers, intrusion alarms
, and other devices that share frequencies with police radar. Generally, the X band is used for these devices.

  • Press the City button to cancel Highway Mode and engage City Mode.
  • Press the City button again to enter City 1 Mode.
  • Press the City button again to enter City 2 Mode.
  • Press the City button a fourth time to cancel City 2 Mode and return the unit to Highway Mode.

In City Mode, weak speed/safety warning system signals give an initial alarm of two beeps and then remain 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, only the X band sensitivity is lowered. 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.

Highway Mode

Highway mode provides full audio warnings any time radar (X, K, Ka, Safety Warning System™) or laser signals are detected and is recommended for open road driving.

For more information on City and Highway modes, please visit our FAQ page on our website: www.whistlergroup.com

Alert Periscopes

Whistler’s Alert Periscopes provide an added attention-getting visual alert. The two extra LEDs flash on and off when the
unit alarms to provide a unique visual alert. This alert can be programmed, through the Option Select Mode ON, OFF or
FLASHING during alerts.

Dim/Dark Mode

Dim/Dark Mode reduces the illumination of the display.

  • Press the Dark button to reduce illumination to a Dim setting.
  • Press the Dark button a second time to engage Dark Mode. The display illumination is further reduced.

Dim or Dark Mode can be engaged during an alert. In Dark Mode, the display goes dark for as long as a signal is being
detected and for 20 seconds after, then the display returns to the dimmer setting.

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

Auto Dim

The Auto Dim feature automatically switches the illumination of the text display between the bright and dim settings according to the GPS time of 7 a.m. and 7 p.m. To manually override the auto-dim feature, use the dark button on the unit. Enter Option Select Mode to turn off the auto dim feature.

Understanding the Display

The unit’s display can be set up to indicate a Cardinal Point Heading, Mode of Operation (Highway and City modes), and Clock.


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.

Feature Engaged Confirmation

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

Vehicle Battery Saver Mode

The Vehicle Battery Saver Mode when selected automatically shuts off the detector after 3 hours. The timer is reset if the detector is turned off, unplugged, or any button is pressed before the timer has expired. The detector will alert you with an audible and visual warning before it shuts off. During this warning, you can momentarily reset the timer by pressing any button. If the unit has automatically turned off, press the Power button to turn the unit back on. Refer to “Option Select Mode” to change the battery-saver mode options.

Red Light/Speed Camera Detection

This unit is capable of alerting to these locations with the updatable database.

Getting a Satellite Lock

Powering up, the unit will begin its search for satellites. During this time, the unit will flash the satellite icon on the display. Please allow several minutes for the unit to lock onto the satellites. This delay is normal when the unit is turned on at least 500 miles from when the unit last received a satellite lock or if several days have passed since its last usage.

NOTE: Driving while initially searching for satellites will take longer than if you are stationary. Acquiring satellites takes much longer the first time.

Camera Alerts

When approaching a known camera, the unit will provide the type of alert (Red Light Camera, Traffic Camera, Speed Camera, or User Location). Example: the display will show TRF CAM and then count down the distance to the camera. Once past the camera location, the unit will provide a beep-beep audio tone, and the word PASS will be shown on the display.
Manual Entry (Waypoint) The unit will save a special location (i.e., a new red light camera or even a “trap”) if you enter it manually. The unit will store 1000 user locations. NOTE: Manual entries must be approximately 330 feet apart to prevent overlapping locations. To manually enter a location, simply press and hold the POWER button and the unit will beep to confirm. Manual entries can be deleted within a certain radius (selected in Option Select Mode). Once
a radius is selected the data can be deleted within the selected Radius or they all can be deleted completely from memory.

X/K and Ka Filter Modes

There are times when a radar detector in another vehicle, can emit a frequency that can cause your detector to falsely alert. These Filter Modes allow you to select the level needed for your area to minimize the occurrences of these false alerts. X/K and Ka Filter Mode factory default settings should provide adequate filtering for most conditions. If you experience excessive alerts due to radar detectors in other vehicles, increase the Filter level for the band received. See Option Selection Mode to change the filter settings.

Speed Selectable Filter Mode

Traveling below the speed selected in option mode will apply the maximum Filter.

NOTE: Enter Option Mode to set Speed Selectable Filter.

Ka Max Mode

Provides enhanced Ka sensitivity. This mode can be selected with or without RSID.

Field Disturbance Sensor Rejection (FDSR) and Traffic Flow Sensor Rejection (TFSR)

Recently many new products that operate on police radar frequencies have been causing nuisance alerts to radar detectors. These radar-based sensors are installed alongside the Highway and more recently on vehicles used as lane change assist / blind spot detectors/collision avoidance systems. TFSR when turned ON is designed to eliminate alerts from specific Traffic Flow sensors. FDSR when turned ON is designed to identify all radar-based collision avoidance systems that operate within the same band as police radar and provide a brief less intrusive alert to keep you informed and aware. A signal strength indicator will help determine your proximity to the source without the continued annoyance of audio.

We suggest you turn FDSR ON if you are experiencing excessive random false alerts when behind select vehicles.

Press the Menu button to enter the Option Select Mode. Each press of the Menu button changes to the next selectable feature. The Dark (D) button and the Quiet (Q) button turn the feature ON/ OFF or Blinking for example. A button must be pressed within 20 seconds or Option Select Mode will automatically be exited.





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 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.

VG-2 Detection 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.

Teach/Tutorial Mode

Provides simulated alerts for each type of signal.
• Press the City and Quiet buttons simultaneously
• Display Shows:


Press the Dark button to exit.

Alert Priority

When two or more signals are received at the same time, the alert priority is:

  1. Laser
  2. Speed Radar
  3. Safety Warning System™

EXAMPLE: If the X band is alerting, then suddenly a laser signal is detected, the laser warning will override the X band alert.

Safety Warning System™

In communities where transmitters are located, the Safety Warning System™ provides over 60 text messages. When
SWS™ has detected the audio alert is Geiger counter-like.

Safety Warning System Text Message

Example: Poor – Road – Surface.

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

Whistler has two features that will assist the driving enthusiast in further identifying threats from laser and Ka-band radar guns.

Ka RSID (Ka Radar Signal IDentifier)

Identify the difference between the likelihood of a Ka threat vs. the likelihood of a Ka false from another source (possible radar detector). Ka RSID feature will educate you about the common Ka speed radar guns by displaying and announcing the nominal police radar frequencies of 33.8GHz / 34.0GHz / 34.3GHz / 34.7GHz / 35.5GHz. Ka alerts that do not fall into the common Ka speed radar windows will be reported only as Ka.

NOTE: This product is not a frequency counter. The unit will categorize the received Ka signal and select the appropriate information. Treat every Ka alert with caution.

LSID (Laser Signal IDentifier)

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 by giving you a 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.


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 than 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 transmitted. Because POP™ Mode radar utilizes the same K or Ka-band frequencies, POP™ Mode Alerts will be displayed as regular radar alerts.


Follow the steps below to update the Laser-Radar Detector.

Step 1: Remove the Laser-Radar Detector from the vehicle and bring it to your PC. Note: You do not need to power the Laser-Rar Detector to update it.

Step 2: Download the update program and install it on your PC.
Note: The program is not MAC-compatible

Step 3: Download and save the .msc file downloaded to your PC. Create a folder for the unit so you can store future updates and save this file into the newly created folder.


Step 4: Open the update program and plug the USB cable into the Laser-Radar Detector.

Step 5: Click the “Open File” button on the update program and locate the saved file from Step 3. Click the “DB Update”
button to install the file.

Step 6: When an update is complete, close the update program, unplug the USB cable, and the Laser-Radar Detector is ready with the new updates.


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.

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.

Displays 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.


Your Whistler detector is expertly engineered and designed to exact 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: The unit does not turn on.

  • Check the fuse in the plug; replace if necessary with a 3 amp, 3AG type.
  • Check the fuse for a lighter socket; replace it if necessary.
  • Make sure the lighter socket is clean.

PROBLEM: Unit alarms when the vehicle hits bumps.

  • Check for loose lighter sockets; tighten and clean
  • Check 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: Low or no audio.

  • Cancel Auto Quiet Mode or City Mode.
  • Check the audio level setting.
  • Check the Speed Selectable Auto Quiet setting in option mode.

PROBLEM: Unit falses too much.

  • If alarms are POP Ka, switch POP Mode to off.
  • If the above option doesn’t help, use a higher Filter setting.
  • If alarms are X or K band and due to radar-based traffic flow sensors or radar-based vehicle blind spot detectors, turn TFSR on.

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 www.whistlergroup.com, before returning your unit for service.


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. 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 (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. Before 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.



This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:

  • This device may not cause harmful interference,
  • This device must accept any interference received, including interference that may cause undesired operation.


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 ranges.

Whistler Laser-Radar detectors receive all current laser guns which operate at a laser wavelength of 905 +/- 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. Currently, the FCC (Federal Communications Commission) permits the 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.

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 “radar detector detectors” (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 detectors and receiving a fine. In addition, instant-on radar is almost always used in combination with an RDD, leaving unsuspecting motorists vulnerable to receiving two tickets; one potentially 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.
