INSTALLATION
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 owner’s manual 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.
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.
INSTALLATION
Windshield Mounting (Continued)
IMPORTANT:
Make sure the unit is level.
Note: Some newer cars have
a plastic safety coating on the
inside of the windshield. The
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 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.
spring and screw on the tip. With use, the screw cap
on the plug may loosen. Retighten it occasionally.

IMPORTANT: Unscrew slowly.
The tip contains a spring which

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
Simply press the Quiet button during the selftest sequence to cancel the self-test audio.
This will not affect radar/laser alerts. To restore
the self-test audio, simply press the Quiet
button during the next self-test.

OPERATION
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.
Auto Quiet Mode
Pressing QUIET before a radar signal is
detected provides an alternate alert pattern,
consisting of four beeps (indicating X, K, Ka or
Safety Radar) 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.
• 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 approximately 20 seconds, 2 beeps are
provided on any new alert, and the 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
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.
• 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 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 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 do 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 Radar) or laser
signals are detected, and is recommended for
open road driving.

OPERATION
TFSR - Traffic Flow Signal Rejection
When turned on in option mode, helps
eliminate excessive alerts from erroneous X and
K-band sources. Traffic flow monitoring systems
are getting more common. Many of these
systems generate radar signals to measure
the flow of traffic across multiple lanes. Most
detectors will alert you to it unnecessarily.
This rejection feature examines the incoming
signal and will aid in reducing the alerts to such
sources.
We suggest you turn TFSR on if you are
experiencing excessive X or K band false
alerts every half mile or so along stretches of
roadway that contain these traffic flow sensors.
Low Profile Alert Periscopes
Whistler’s Low Profile 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.
