The Whistler Group WH16 Manuel D’Utilisation

Installation

• Locate the tab near the button openings and 

insert this end first into the unit.

• Gently snap in the other tabs as you work your 

way to the back of the unit.

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 vehicle’s owner’s manual to

determine if your windshield has this coating.
• Avoid placing unit in direct contact with windshield.
• Avoid placing unit in direct sunlight.
• To reduce the possibility of theft, conceal your 

unit when not in use.

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.

• 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.

Programmable Text Display 

(XTR 425/560 only)
The above models have the ability to modify the
standard laser/radar detector’s display.
“WHISTLER”, “HIGHWAY”, “CITY”, “CITY 1”,
and “CITY 2” can be changed to display your
name, or any combination of 8 characters.  For
example, “HIGHWAY” can be changed to “GO
4 IT”. 
Note: A space is counted as a character.

are driving. You should not use any device in a
vehicle that may distract you from observing the
road ahead.

To Modify the Text

• Press and hold the Quiet button to enter 

Option mode (see page 13 ). Once “USER 

TEXT” is displayed simultaneously press and 

release the VOL UP and VOL DOWN buttons 

each time to scroll through the text that can 

be customized. When a text is selected, (use 

WHISTLER for example) the display will 

indicate “WHISTLER” with a blinking cursor 

under the letter “W”.  

Note: The blinking cursor indicates that this is
the first letter ready to be changed.

Programmable Audio Tones

(XTR 560 Only)

Model XTR 560 also has the ability to modify the
standard laser/radar detector’s audio tones. Audio
tones such as “X Band”, “K Band,” “Ka Band” “Ku
Band” and “Laser” can be changed to play up to 15
seconds of a favorite tune, phrase, saying, almost
anything you like. When the unit detects K band, for
example, the K band voice will now be followed by
what was recorded for K band.
TIP: Turn off the voice option to have the unit
respond only with the custom recorded alerts.

To Modify the Audio, Part 1

displayed, simultaneously press and release the 

VOL UP and VOL DOWN buttons to allow for 

selection of Normal Tones or Custom Tones. 

(Display shows “ X - Norm” or “ X - Cust”)  The 

Vol Up button selects Custom Tone and Vol Down 

button selects Normal Tone.  The Quiet button 

advances the menu to the next band selection. 

“X - Norm”—› “K - Norm”—› “Ka - Norm” —› 

“Ku - Norm” —› “L - Norm”

The PWR button exits User Tone Mode, but still
remains in Option Mode. Press the PWR button
again to exit Option Mode.

To Modify the Audio, Part 2

first band ready to record up to 15 seconds of 
audio. 

• Press and release the Quiet/Record button 

advances the recording feature to the next 
band.

• Press both volume buttons for less than 2 

seconds and release to exit Record/Playback 
mode.

NOTE: Custom Mode automatically exits within 20

seconds if a button is not pressed. Messages are

kept in memory and are not affected by resetting

the factory features. See “Reset Features” section of

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 which
share frequencies with police radar. Generally, X
band is used for these devices.

• Press City to cancel Highway mode and 

engage City. 

• Press City again to enter City 1 Mode 

- display shows ‘C1 Lo X’. (XTR 425/560)

• Press City again to enter City 2 Mode 

- display shows ‘C2 No X’ (XTR 425/560)

• Pressing City a fourth time cancels City 2 Mode

and returns the unit to Highway Mode.

In City Mode, weak speed/safety radar signal
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, only the X band sensitivity is
lowered. In City 2 Mode, X-band is not detected.
Caution: Some towns/small cities may still be

Engaging/Disengaging VG-2 

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 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.

Backlight Setting 

(XTR 425/560)

The backlighting (B/L) can be programmed to

be illuminated all the time, only when alarming,

or choices in-between.  The options are

selectable by pressing and holding the

Power/Dim button on the unit. The options are:
OFF-OFF = B/L is off at idle and off during an alarm.

OFF-DIM = B/L is off at idle and dim during an alarm.

OFF-BRT = B/L is off at idle and bright during an alarm.

DIM-OFF = B/L is dim at idle and off during an alarm.

DIM-BRT = B/L is dim at idle and bright during an alarm.

BRT-BRT = B/L remains bright at idle as well as alarming.

Backlight will turn on, if selected, while the unit

alarms and remain on for 3 seconds after the unit

stops alarming. When any button is pressed the

backlight will illuminate at the dim setting and

remain on for 3 seconds afterwards. The backlight

will also illuminate while in option mode.

Dim/Dark (XTR-325 only)

Dim/Dark Mode reduces the illumination of the
display.
• Press and hold B/L button for 2 seconds to 

reduce illumination to a Dim setting.

• Pressing and holding the B/L button for 2 

seconds a second time engages 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 for 20 seconds
after, then the display returns to the dimmer
setting.
• Pressing  and holding the B/L button a third 

time restores full illumination to the display.
