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 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 affects radar  
 signals. Consult your dealer or the user guide  
 to determine if your windshield has this coating.
• Avoid placing unit in direct contact with the wind  
 shield.
• To reduce the possibility of theft, conceal the unit  
 when not in use.
INSTALLATION
Rubber Bumper
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: Make sure the unit is level.
Note: 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 user guide or ask your dealer. We 
recommend that you do not leave the suction cup 
bracket on the windshield in direct sunlight. If the 
detector is removed, this may cause blistering of the 
dash in some vehicles.
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, the screw cap on the plug may 
loosen. Retighten it occasionally.
OPERATION
Power On Self Test & Volume
Each time your Whistler detector is turned on, an 
automatic self-test sequence confirms that the 
speaker and visual displays are functional. To 
increase the volume, continue turning the 
volume knob.
Integrated Real Voice
When selected, Real Voice® will be used to 
articulate the following:
 1. Band Identification
 2. Safety Warning System messages
 3. Feature Selection
Voice OFF/ON is selected by holding quiet 
button for approximately 2 seconds. Voice ON 
will announce “caution”, Voice OFF will give a 
double beep.
Feature Engaged Confirmation
Each time a button is pressed, one beep confirms 
the feature is “on”, two beeps confirm feature 
“off”.

Self Test Mute
Press the Quiet button during the self-test 
sequence to cancel the Self-Test audio. This will 
not affect radar/laser alerts. To restore the SelfTest audio, press the Quiet button during the 
next Self-Test.
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.
Auto Quiet Mode
Pressing QUIET before a radar signal is detected 
provides an alternate alert pattern, consisting 
of several beeps (indicating X, K, Ka or Safety 
Warning System™) followed by reduced tone. 
The reduced tone 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.
• Press Quiet (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.
Quiet Mode
Quiet mode cancels audio during an alert and any 
new alert within 20 seconds. After 20 seconds of 
no alerts, the audio is restored for any new alerts.
• 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.

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 button to cancel Highway Mode  
 and engage City Mode. 
• Press City button again to enter City 1 Mode 
• Press City button again to enter City 2 Mode 
• Press 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 
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 Mode does not change the 
audio alert for laser or VG-2.
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.
Field Disturbance Sensor Rejection (FDSR) 
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. 
NOTE: TFSR and FDSR are ON by default and 
not selectable on the Z11R+/Z-11RS
Alert Periscopes
Whistler’s 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.
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.
Engaging/Disengaging VG-2
See Option Select Mode to turn this feature on.
Vehicle Battery Saver Mode
The Vehicle Battery Saver Mode automatically shuts 
off your detector within 6 hours. 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.
Stay Alert Feature (Z-15R+/Z-15RS Only)
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 button during or immediately  
   after the alert is given.
The “H” or “C” will flash indicating Stay Alert is 
activated. 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 and the display flashes all the LEDs.
• 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. 
Laser Audio / Visual Alerts
When a laser signal is detected, model 
Z-11R+/Z-11RS display indicates alert by illuminating 
the “V/L” and scrolling the signal strength indicators 
from right to left. Model Z-15R+/Z-15RS display 
indicates an “L” on the display. 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. Model Z-11R+/Z-11RS will flash 
the alert strength indicators at their fastest rate; on 
model Z-15R+/Z-15RS a “P” will be displayed. 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.

VG-2 ALERTS
VG-2 Detection Mode
The VG-2, also known as a “radar detector 
detector,” is a special receiver used by police to 
detect signals radiated by a radar detector. See 
speed monitoring section for more information 
on VG-2.
When the VG-2 signal is detected, the VG-2 
alert is sounded. After 3 seconds, the audio 
is cancelled and the VG-2 indicator flashes at 
a slower rate. Every 30 seconds, the detector 
checks for a VG-2 signal. This cycle is repeated if 
the VG-2 signal is detected again. If no signal is 
detected, two beeps are provided indicating an 
“all clear” condition.
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.

Care & 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. 
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: HSXWH23
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.
ARE DETECTORS LEGAL?
(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 
then 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 only alarm if an officer is 
transmitting on any one of the above radar bands.
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. 
SPEED MONITORING SPEED MONITORING
A radar transmission can cover more than a four-lane 
highway at a distance of 1,000 feet, compared with a 
laser transmission which covers about 3 feet at 
the same distance. For best protection, keep these 
points, listed on the following section, 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 ± 50 nm including but not limited to the  
 following:
• Ultra Lyte
• LTI 20 - 20
• LTI TruSpeed® S
• Pro Laser™ I II III
• Laser Ally
• Laser Atlanta® Stealth Mode
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:
• Pacing - A patrol car drives behind you and  
 matches your driving speed.
• Vascar/Aircraft - The time it takes a vehicle  
 to travel a known distance is measured. 
Radar Detector Detectors (VG-2) Spectre The 
Interceptor VG-2, or simply VG-2, is a 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, the VG-2 is known as a 
“radar detector detector”. The VG-2 is a tool used 
by the police to identify radar detector equipped 
vehicles. If caught, in a state where detectors 
are illegal drivers risk losing their radar detector 
and receiving a fine. In addition, instant-on 
radar is almost always used in combination with a 
VG-2, leaving unsuspecting motorists vulnerable 
to receiving two tickets—one potentially for 
speeding, the other for possession of a detector.  
Having a radar detector capable of detecting the 
VG-2 may alert you to the presence of a speed 
trap.
For more information on speed monitoring  
technologies, please visit our FAQ page on our 
website: www.whistlergroup.com
It is the responsibility of the individual radar 
detector operator to know and understand the 
laws in your area regarding the legality of the 
use of radar detectors.
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.

rates when:
• The unit’s original warranty has expired.
• A dated store receipt is not supplied.
• The unit has been returned without its serial  
number.
• The unit has been abused, modified, installed 
improperly, or had its housing removed.
The minimum out-of-warranty service fee for your 
Whistler Z-11R+/Z-11RS detector is $35.00 (U.S.) 
and $40 (U.S.) for the Z-15R+/Z-15RS detector. If 
you require out-of- warranty service, please return 
your unit as outlined in the section “Service Under 
Warranty” along with a certified check or money 
order in the amount stated above. Payment may also 
be made by MasterCard, VISA or American Express; 
personal checks are not accepted.
In the event repairs cannot be covered by the

a Whistler technical service specialist who will 
outline options available to you.
If you elect not to have your unit repaired, it will be 
returned to you along with your certified check or 
money order.
