FEATURE DESCRIPTIONS
1. Bracket Release Button – provides quick
and easy release of the mounting bracket.
2. Speaker – provides distinct audio warnings
for X, K, Ka band radar, safety warning system,
laser and VG-2.
3. Mounting Bracket Location – slot holds
mounting bracket firmly.
4. Radar Antenna – compact, high-efficiency
antenna receives radar signals.
5. Front Laser – high gain optical lens provides
increased sensitivity and field of view for
leading-edge laser detection.
6. Rear Laser – an integrated optical waveguide
provides superior detection of laser signals
transmitted from behind.
7. City Button - reduces the annoyance of false
alerts typically encountered in urban driving
areas.
8. Quiet Button - pressing QUIET before a radar
signal is detected engages Auto Quiet Mode
which provides “clicking” sounds after the
initial warning. Pressing QUIET during a radar
encounter silences audio alerts, while allowing
visual alerts to keep you informed.
9. Power / Volume Control - turns unit on/off
and adjusts audio level.
10. Dim / Dark Mode - engages Dim/Dark modes.
11. Menu Button - enters option select mode.
12. Numeric Icon Display - combines icon
display with a 7 segment digital display that
shows signal strength indication and band
identification.
13. Alert Periscopes - provide an additional
attention getting visual alert.
14. X-band Icon - indicates the unit is receiving a
X-band signal.
15. K-band Icon - indicates the unit is receiving a
K-band signal.

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 affect radar
signals. Consult your dealer or the user guide
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.

16. Ka-band Icon - indicates the unit is receiving a
Ka-band signal.
17. V - indicates that the unit is receiving a VG-2
signal. Indicates that VG-2 is engaged.
18. H - indicates unit is in Highway mode.
19. C - indicates that the unit is operating in city
mode.
20. Signal Strength Icon - indicates the strength
of the signal being detected.
21. L - indicates that the unit is receiving a laser
signal.
22. Power Jack - provides connection for the
power cord
INSTALLATION

INSTALLATION
6
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 user guide 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.
Windshield
Mounting
IMPORTANT: Make sure the unit is level

INSTALLATION
7
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: Cord fits tightly into detector. When
installing the cord, expect some resistance.
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.

OPERATION
8
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® (CR73 Only)
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
Self-Test audio, press the Quiet button during the
next Self-Test.

OPERATION
9
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 clicking. After 20 seconds of no
alerts, the audio is restored for any new alerts.
• 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
Pressing Quiet cancels the 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.

OPERATION
10
City/City 1/City 2 Mode(cont’d)
• Press City button again to enter City 2 Mode.
• Press City button a fourth time to cancel City 2
Mode and returns 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, 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.
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.
