Muting an Alert
Your detector allows you to quickly turn Off an audio Alert by momentarily
pressing the Mute button. If you press the Mute button a second time
during the Alert, the audio Alert will be turned back On.
Auto Mute Mode
Auto Mute will automatically reduce the audio volume of all alerts
after four seconds for as long as the signal is detected. The factory
setting for Auto Mute is On.
IntelliMute
IntelliMute is a unique feature that allows you to avoid alerts you don’t need
to hear because you are stopped or moving slowly. By sensing the “revs”
(RPMs) of your engine, IntelliMute knows when you are at low speed and
automatically mutes audio radar alerts.
Before IntelliMute will work, you must set an activation point for your engine’s
revs (see page 10). Whenever the revs are below that point, IntelliMute will
begin muting. The activation point will be stored in memory and recalled
each time the power is turned On. The factory setting is IntelliMute Off.
NOTE
IntelliMute may not work with some vehicles because it cannot sense
the engine’s revs. In such cases, you can reduce unwanted audio alerts
by using Auto Mute and City mode when appropriate.

What to Remember While Using IntelliMute
IntelliMute works with both City and Auto Mute modes.
Whenever your engine revs are below the activation point, the dot next to
the large character on the right side of the display will remain lit. Above the
activation point, the dot will blink twice every two seconds.
If, for any reason, the unit stops sensing your engine’s revs, IntelliMute
will indicate an error and automatically turn Off.
The rev point you set will be stored in the unit’s memory when power is
turned Off and recalled each time the power is turned On.
NOTE
The rev point must be reset if you use your detector in a different vehicle.
NOTE
When initially choosing your IntelliMute activation point, a setting
of approximately 300 to 600 RPMs above idle is recommended.
You can reset the activation point at any time to fit your individual
preferences and driving style.
Setting the IntelliMute Activation Point
Your detector must be installed in your vehicle.
CAUTION
Do not attempt to set the rev point while driving.
Your vehicle should be parked and idling.
IntelliMute must be turned On before setting the activation point. Depending
on whether the unit is in Tone Alert or Voice Alert mode, you will hear a series
of beeps or voice messages as you follow the steps on the next page.

VG-2 and Spectre I & IV+ Alert Settings
Police use radar detector detectors (RDDs) to spot users of radar detectors.
Your detector is able to identify signals from VG-2,Spectre I and Spectre IV+
RDDs and can provide alerts when any of these or similar devices are in use
near your vehicle.
Your detector can be spotted by Spectre IV+ RDDs, but is invisible to VG-2 and
Spectre I RDDs. You can choose whether you want to be alerted to VG-2 and
Spectre I & IV+ RDD signals. The factory setting for VG-2 and Spectre I & IV+
alerts is Off.
IntelliMute Pro
IntelliMute Pro prevents detection by radar detector detectors (RDDs) such as
VG-2, Spectre I and Spectre IV+ when traveling at slower speeds. It is intended
for use by experienced users only.
When IntelliMute Pro is turned On, and engine RPMs are below the IntelliMute
activation point, your detector’s radar detection circuits are turned Off to
prevent detection by RDDs.
Before IntelliMute Pro can be turned On, you must have turned On and Set the
IntelliMute activation point. (See pages 9 through 11.)

Detection •
Signals Detected
The tables on the following pages show you the types of Signals your detector
will detect, as well as the voice and visual alerts it provides for each of them.
Audio Alerts
In Voice Alert mode you will first hear several tones, then a voice message
announcing the type of signal detected, followed by more tones. In Tone Alert
mode, you will hear the tones only.
In both Voice Alert and Tone Alert modes, a distinctly different alert tone is
used for each type of signal detected (including separate tones for each laser
signal). For X, K, Ka and Ku band radar signals, the tones will repeat faster as
you approach the signal source. The repeat rate of the tones gives you useful
information about the signal detected. (See responding to alerts on page 18.)

Pop Alert
The Pop Mode Radar Gun is a single-pulse Doppler radar that is a feature
of a K and Ka (Bee III Ka radar gun) band Instant-On radar gun. It uses
asingle, short-time pulse to measure the target vehicle’s speed.
The Pop mode receiver senses Pop singles beyond the effective range of
Pop radar guns. As the Pop mode receiver is so sensitive, you should limit
the use of Pop Detect mode to highway and rural driving.
Pop Alert will alert you to Pop radar signals. During the alert, the unit
continues to detect other signals. The factory setting is Pop Detect Off.

Radar Speed Monitoring Systems
Three band frequencies have been approved by the Federal Communications
Commission (FCC) for use by speed monitoring radar equipment:
X band 10.525 GHz
K band 24.150 GHz
Ka band 33.400 – 36.00 GHz
Your detector detects signals in all three radar bands, plus Ku band (13.435 GHz),
which is an approved frequency used in parts of Europe and Asia.
VG-2 and SpectreI&IV+
VG-2 and Spectre I & IV+ are radar detector detectors (RDDs) that work by
detecting low-level signals emitted by most radar detectors. Your detector
does not emit signals that can be spotted by VG-2 and Spectre I RDDs.
However, your detector can be spotted by Spectre IV+ RDDs. Your unit
detects signals from these or similar devices and will alert you when such
adevice is in use near your vehicle.
Safety Alert Traffic Warning System
FCC-approved Safety Alert transmitters emit microwave radar signals that
indicate the presence of a safety-related concern. Depending on the frequency
of the signal emitted, it can indicate a speeding emergency vehicle or train,
or a stationaryroad hazard.
Because these microwave signals are within the K band frequency,most
conventional radar detectors will detect Safety Alert signals as standard
Kband radar. Your detector, however, is designed to differentiate between
standard K band and Safety Alert signals, and give separate alerts for each.
Safety Alert technology is relatively new.Safety Alert transmitters can
be found in limited numbers in all 50 states, but the number is growing.
Depending on your location, you may not receive these alerts regularly
and may often encounter emergency vehicles, trains and road hazards
without being alerted. As the number of transmitters increases,
these alerts will become more common.
When you receive such an alert, please watch for emergency vehicles ahead
of you, on cross streets and behind you. If you see an emergency vehicle
approaching, please pull over to the right side of the road and allow it to pass.
Description Interpretation Recommended
Response
Tone repeats slowly at
first, then speeds up
rapidly.
Probably police radar. FULL ALERT
Tone sounds one
time only. Probably a false alarm, but possibly pulsed radar,
VG-2, or Spectre I or IV+
nearby.
Exercise caution
Tone instantly begins
repeating rapidly. Radar,VG-2 or Spectre I or IV+ nearby has been
activated suddenly.
FULL ALERT
Tone repeats slowly as you
approach a hill or bridge,
then speeds up sharply as
you reach it.
Probably police
radar beyond the
hill or bridge.
FULL ALERT
Tone repeats slowly
for a short period. Probably a false alarm. Exercise caution
Any type of laser alert. Laser alerts are
never false alarms. FULL ALERT
Any Safety Alert. You are nearing an
emergency vehicle,
railroad crossing,
or road hazard
(construction,
accident, etc.).
Exercise caution
Responding to Alerts
Instant-On Detection
Your detector is designed to detect Instant-On speed monitoring signals,
which can suddenly appear at full strength.
NOTE
You should take appropriate action immediately
whenever an instant-on alert is given.

LIDAR (Laser)
The correct name for the technology that most people refer to as
laser is actually LIDAR,which stands for Light Detection and Ranging.
LIDAR operates much like radar. Its signal spreads out like a radar signal, though
not as widely. Unlike radar, LIDAR must have a clear line of sight to its target
vehicle throughout the entire measurement interval. Obstructions such as sign
posts, utility poles, tree branches, etc., will prevent valid speed measurement.
Some common questions about LIDAR include:
■Does weather have any affect on LIDAR?
Yes. Rain, snow, smoke, fog or airborne dust particles will reduce the
effective range of LIDAR and can, if dense enough, prevent its operation.
■Can LIDAR operate through glass?
Yes. Newer LIDAR guns can obtain readings through most types of glass.
However, the laser pulse also can be received through glass to trigger
an alarm by your detector.
■Can LIDAR operate while in motion?
No. Because LIDAR operates by line of sight, the person using it cannot
drive the vehicle, aim and operate the gun all at the same time.
■Is LIDAR legal to use?
Yes. It is legal in all 50 states.
Maintenance •
Maintenance of Your Radar Detector
Your detector is designed and built to give you years of trouble-free performance
