OPERATION
Alert Periscopes
Whistler's new Alert Periscopes provide an added
attention getting visual alert. The two extra LEOs
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: 1. flash for all
alarms, 2. remain on, or 3. turn LEOs off
completely.
VG-2 Mode
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 3seconds the audio is canceled and the
display no longer flashes. This cycle is repeated
if the VG-2 signal is detected again.
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. (See
page 17 for more information)
Vehicle Battery Saver Mode
The Vehicle Battery Saver Mode automatically shuts
off the detector after 3
hrs (6 hrs. for XTR-475). The
timer
is reset if the detector is turned off,

timer
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
timer by pressing
any button. If the unit has
automatically turned off, press any button to turn the
unit
back on.
Refer to "Option Select Mode" for instructions
for deactivating battery saver mode feature.

OPERATION
Filter Mode (N/A on XTR-500/550/555)
There are times when aradar detector in another
vehicle, can unintentionally emit a frequency
which can cause your detector to falsely alarm.
The Whistler Filter Mode options provide
additional signal processing to minimize the
occurrences of these false alarms. Filter mode
provides normal processing. Filter 1 mode
provides additional signal analysis before
alarming.
Filter
Mode is the factory default setting and
should provide adequate filtering for most
conditions. If you experience excessive alerts
due to radar detectors in other vehicles, try Filter
1 mode. Filter Mode analysis occurs in Highway
Mode and all City Modes. See Option Selection
Mode to change the filter settings.

VCi·2 ALERTS
VG-2 AudioNisual Alerts
Note: You must turn this feature on before /t will deted VG-2
When aVG-2 signal is detected, the detector "hides" its
own radiated signal and becomes
undetectable by the
VG-2. Every 30 seconds, the detector checks for aVG-2
signal. If aVG-2 signal
is still present, the unit continues
to hide and repeats the VG-2 alert. If no signal is
detected, two beeps are provided, indicating an "all
clear" condition. During aVG-2
Alert X, K, and Ka band
signals cannot
be received (see pg. 22).
Alert Priority
When two or more signals are received at the same
time,
the alert priority is:
1. Laser 2. VG-2 3. Speed Radar 4. Safety Radar
Example: If Xband is alerting, then suddenly aVG-2

CARE AND MAINTENANCE
Care And 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,
c1eaners,
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
(exceptVirginia
and Washington, D.C., which have
local
regulations restricting the use of radar
receivers in
any vehicle) when used in
automobiles or light trucks (under 10/000 Ibs.).
The Federal HighwaY' Administration (FHWA)
issued a
regulation, effective January, 1994 which
prohibits radar and laser
detector use in vehicles
over 10/000 Ibs. Prior
to the FHWA regulation,
laws existed in
New York restricting the use of radar
detectors
in trucks over 18/000 Ibs. and in Illinois in
trucks over 26/000 Ibs.

SPEED MONITORING
Radar Facts
Aradar gun operates by transmitting radio
waves at certain frequencies which reflect off
objects and are picked up by the radar gun's
receiving section. When aradar beam reflects
off a moving target, ameasurable frequency shift
occurs. The radar unit converts this shift into miles
per hour to determine your vehicle's speed.
Currently, the FCC permits operation of traffic
radar guns at XBand (10.500 -10.550 G Hz), K
Band (24.050 -24.250 G
Hz), and Ka Band (33.400
-36.000 GHz).
Note: Aradar detector will only alarm if an
officer is transmitting on anyone of the above
radar bands.
