INSTALLATION

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

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.

INSTALLATION

Power 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.

Fuse Replacement

The lighter socket plug is equipped with a

replaceable 2 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 which may fly out when

disassembling. 

Insert the new fuse with the

spring and screw on the tip. 

With use, screw

cap on plug may loosen. Retighten

occasionally.

Unscrew the tip of the lighter socket plug 

carefully when replacing the 2 amp fuse.

INSTALLATION

Power On and Self Test

Each time your Whistler detector is turned

on, an automatic self-test sequence confirms

that the speaker and visual displays are

functional.

Feature Engaged Confirmation

Each time a button is pressed one beep confirms

feature “on”, two beeps confirm feature “off”.

Auto Quiet Mode

Pressing QUIET before a radar signal is 

detected provides an alternate alert pattern,

consisting of several beeps (indicating X, K

or Ka) followed by clicking. The clicking will

continue for as long as the detected signal is

present or any new signal is detected within

20 seconds, becoming more rapid as the

strength of the signal increases.

Quiet Mode

Quiet cancels audio during an alert and any new

alert within 20 seconds. After approximately 20 

seconds,  2 beeps are provided on any new alert,

and unit then remains quiet.

• Press Quiet to cancel the audio.

• Press Quiet a second time during an alert 

to restore the standard audio alert pattern;

or turn the unit off, then on.

OPERATION

Audio Level Adjustment

The audio levels can be adjusted high to

low or low to high.

• Move Power/Volume control back to 

increase audio level.

• Move Power/Volume control forward 

to decrease audio level. 

Highway Mode

The icon “P” indicates Highway Mode. It

provides full audio warnings any time radar (X,

K or Ka) or laser signals are detected, and is

recommended for open road driving.

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 button to cancel Highway 

mode and engage City Mode. The 

display will switch from “P” to “C”.

• Press City button again to enter City I 

Mode.

• Press City button again to enter City II 

Mode.

Note:

After 3 seconds, “I” or “II” City

Mode indicator turns off.

• Pressing City button a fourth time 

cancels City II Mode and returns the 

unit to Highway Mode.

OPERATION

OPERATION

City/City I/City II Mode - continued

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 I and City II Modes operate the same

as Highway Mode, but in City I Mode,

only the X band sensitivity is lowered. In

City II 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.

Vehicle Battery Saver Mode

The Vehicle Battery Saver Mode

automatically shuts off your detector after 6

hours if you forget to turn it off. The timer is

reset if the detector is turned off, unplugged

or any button is pressed before the time 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 unit by pressing any button. This

will reset the timer. If the unit has

automatically turned itself off, press any

button to turn the unit back on.

Engaging/Disengaging VG-2

See Option Select Mode to turn this feature

on (see pg. 15).

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 

engages Dark Mode. In Dark mode 

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 for 20 seconds after, then

the display returns to the dimmer setting.

• Pressing the Dark button a third 

time restores full illumination to the 

display.

Setting Saver

Setting Saver saves your personalized

settings so that when the detector is turned

off and then on again, you do not have to

re-enter them.

Ka Narrow Band

Many countries do not share the same Ka

radar guns as the USA. Having a radar

detector that scans the complete Ka band

may not be necessary if your Country is

only using one or more of the following

(34.0 or 34.3 GHz). See Option Select

Mode to engage Ka Narrow mode. Icon

“I” shows Ka Narrow on, “III” shows Full

Ka on.

OPERATION

Laser Audio / Visual Alerts

When a laser signal is detected, the

display indicates a laser by scrolling the

alert Icon’s from right to left. The audio

alert is continuous for a minimum of 3

seconds.

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.

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

flashes the alert strength indicators at

their fastest rate.  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.

Mounting Guidelines

• Mount the unit as low as possible near the 

center of the windshield.  

• Do not mount your unit behind wipers, 

ornaments, mirrored sunscreens, etc. These 

obstructions have metal surfaces which 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 affect radar 

signals. Consult your dealer or the owner’s 

manual supplied with your vehicle to 

determine if your windshield has this coating.

• Avoid placing unit in direct contact with wind

shield.

• To reduce the possibility of theft, conceal your

unit when not in use.

IMPORTANT:

Make sure the unit is level.
