illegal, may be enforced by your local law enforcement officials until and unless  

they are prohibited from doing so by federal court action.

involved in traffic accidents. It is only intended to alert  

the motorist that an emergency vehicle equipped with a Cobra Safety Alert  

transmitter is within range as defined by that product. Please call local fire  

and police departments to learn if coverage exists in your area.

Safe Driving 

Motorists, as well as operators of emergency or service vehicles, are expected to exercise all due

Installation 

Where to Mount Your Unit

 You will get optimum performance from your detector if you 

Mount

 it at a point 

approximately in the center of the vehicle, as low as possible on the front windshield 

without obstructing the unit’s view of the road either to  

the front or rear. Make sure the unit is level with the road. You can also 

mount it directly on the dashboard. 

The unit’s lens must not be blocked and the LaserEye should have a clear view out the 

back window to allow 360° detection.

Radar and laser 

signals pass through 

glass but not through 

other materials and 

objects. Objects that 

can block or weaken 

incoming signals 

include: 

g

  Windshield wiper blades

g

  Mirrored sun screens

g

  Dark tinting at the top of the windshield

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. You will 

hear a series of beeps as you follow the steps on the next page.

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  

a single, 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.

Detection  

Signals Detected

The tables on the following pages show you the types of 

Signals

 your  

detector will detect, as well as the visual alerts it provides for each of them.

Audio Alerts

 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.)

Visual Display

 An indication of the type of signal detected will appear in the UltraBright  

data 

Display

. During X, K, Ka and Ku alerts, a number will also appear,  

indicating the strength of the signal detected. (1 = weakest, 5 = strongest)

During pop alerts, the letter 

P

 

will  

appear; and during laser alerts,  

the letter 

L

 will appear, instead of  

the signal strength indication.  
 During VG-2 or Spectre I or IV+ 

alerts, the letter 

V

 will appear.  

It will be steady during VG-2  

and blink during Spectre I or IV+.

 During Safety Alert the letter 

S

 

will appear.

Understanding Radar and Laser 

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 Spectre I & 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  

a device 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 stationary road hazard. 
Because these microwave signals are within the K band frequency, most conventional 

radar detectors will detect Safety Alert signals as standard  

K band 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.

Instant-On Detection

Your detector is designed to detect

Understanding Radar and Laser  

and Maintenance

Your Detector

English

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 without the 

need for service. No routine 

Maintenance

 is required.

If your unit does not appear to be operating properly, please follow these troubleshooting 

steps:

   Make sure the power cord is properly connected.

    Make sure the socket of your vehicle’s cigarette lighter is clean and  

free of corrosion.

   Make sure the power cord’s cigarette lighter adapter is firmly seated  

in your cigarette lighter.

   Check the power cord fuse. (Unscrew the ribbed end cap of the  

cigarette lighter adapter and examine the fuse. If required, replace  

it with a 2-amp fuse only.)
