Whistler CR75 Leaflet

™

 

Because POP

™

 Mode radar utilizes the same

K or Ka band frequencies, POP

™

 Mode Alerts will be 

displayed as regular radar 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. 

When a laser signal is detected the audio alert is 

continuous for a minimum of 3 seconds. 
 • The Display Shows:
 

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.

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. 22)

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 Warning System
Example: If X band is alerting, then suddenly a VG-2 

signal is detected, the VG-2 warning will 

override the X band alert.

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 

•  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 pg. 8-9).
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 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.

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.

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.
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.

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, 

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.

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 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 wavelength of 905 

+/- 50nm.

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!

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.

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 19), 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: Having a radar detector capable of detecting the 

VG-2 may alert you to the presence of a speed trap.

  without any power lines.

3. Press the Menu button until display shows 

  CAL MODE. Then press the Dark and Quiet  

  buttons simultaneously. The display shows    

 (scrolling):

4.  If calibration does not automatically finish, 

press the Dark and Quiet buttons simultaneously 

to complete calibration.  The unit will beep twice 

and display shows, for example:

Note: In Combo Mode, an “H” or “C” will be 

shown to indicate mode of operation. 

Important: If unit mounting is relocated in 

the vehicle, (i.e., visor to windshield mounting 

or dash mounting), or if the unit is moved 

to another vehicle, you must recalibrate the 

compass.
