Mounting
Mounts easily on windshield or dashboard

This booklet describes the simple steps for mounting and setting up your detector. It also provides helpful information about how radar and laser guns are used and how you can interpret the alerts you receive.

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 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:

• Windshield wiper blades
• Mirrored sun screens
• Dark tinting at the top of the windshield
• Heated windshields currently available on some vehicles
  (Instaclear for Ford, Electriclear for GM.) Consult your dealer to see if you have this option.

Windshield Mounting

1. Attach the rubber cups to the bracket.
   
2. Make sure the rubber cups and your windshield are clean.
3. Push the bracket firmly onto the windshield.
   
4. Attach the detector to the bracket. Check the angle of the unit.
   
5. To adjust the angle if necessary, gently push or pull on the bracket to bend it. DO NOT use the detector to bend the bracket.

Getting Started

To Turn On the Unit and Adjust the Audio Volume
Rotate the On-Off/ Volume control clockwise (away from you).	Tone	Visual Display
	Three beeps	appears in the display indicating that the power is On

NOTE
In some vehicles, power is supplied to the cigarette lighter even while the ignition is Off. If this is the case with your vehicle, you should turn Off or unplug your detector when parking for lengthy periods.

Auxiliary Audio Jack

The Auxiliary Audio Jack can be used to connect external speakers in environments with high ambient noise levels. The internal speaker will be disconnected. (This uses a mini stereo audio connector.)

Settings

When changing the Settings on your detector, please keep in mind:

• Buttons can have multiple functions.
• All settings will be stored in memory when the power is turned Off and recalled when the power is turned back On.

Highway/City Mode

Setting your detector to City mode delays all X band audio alerts until the signal strength reaches Level 3. (A single beep will sound when the signal is first detected.) This will reduce false alerts while you are driving in, or near, urban areas where there are many sources for conflicting X band signals such as microwave towers and automatic door openers.

To change settings, follow the procedure listed below, which indicates what you will see and hear as you complete each step. The factory setting is Highway mode.

To Change From Highway Mode to City Mode
Press and release the City button.	Tone	Visual Display
	One beep	appears in the display

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.

To Turn Auto Mute On
Press and release the Mute button again while no alert is occurring.	Tone	Visual Display
	Two beeps	None
To Turn Auto Mute Off
Press and release the Mute button while no alert is occurring.	Tone	Visual Display
	One beep	None

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. 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.

To Turn IntelliMute On
Press and release the IntelliMute button.	Tone	Visual Display
	Two beeps	Dot appears next to the large character on the right
To Turn IntelliMute Off
Press and release the IntelliMute button again.	Tone	Visual Display
	One beep	None

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.

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 below.

To Set the IntelliMute Activation Point
Press and hold the IntelliMute button for two seconds.	Tone	Visual Display
	Two beeps	None
Rev your engine to the level you wish to set (recommend slightly above idle) and hold revs steady for two seconds.	None	Three bars will flash in succession
At the desired rev level, press and release the IntelliMute button.	Three beeps	All three bars flash three times

NOTE
If the unit is unable to sense usable pulses within three seconds or if you do not set a rev point within 20 seconds of beginning these steps, IntelliMute will indicate an error and automatically turn Off.

Tone	Visual Display
Four beeps	E appears

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.

When IntelliMute Pro is On, NO radar signals will be detected and NO alerts will be given at RPMs below the IntelliMute activation point.

To Turn IntelliMute Pro On
While no signal is being detected, press and hold both the IntelliMute and City buttons for four seconds.	Tone	Visual Display
	Two beeps	c or h will blink
To Turn IntelliMute Pro Off
Press and hold both the IntelliMute and City buttons for four seconds.	Tone	Visual Display
	One beep	c or h will show steady

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.

To Turn VG-2 and Spectre I & IV+ Alerts On and Off
While no signal is being detected, press and hold the Dim button for four seconds.	Tone	Visual Display
	On = Two beeps	V will blink twice in the display
	Off = One beep	V will blink once in the display

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.

To Turn Pop Alert On and Off
While no signal is being detected, press and hold both the Dim and City buttons for four seconds.	Tone	Visual Display
	Pop On = Two beeps	P will blink twice in the display
	Pop Off = One beep	P will blink once in the display

Radar Alert Settings

The detector allows you to choose whether it will show alerts on the X, K and Ku bands. The factory settings are: X Band and K Band On; Ku Band Off.

To Turn X Band On and Off
While no signal is being detected, press and hold both the Dim and Mute buttons for four seconds.	Tone	Visual Display
	X On = Two beeps	X will blink twice in the display
	X Off = One beep	X will blink once in the display
To Turn K Band On and Off
While no signal is being detected, press and hold both the Mute and City buttons for four seconds.	Tone	Visual Display
	K On = Two beeps	K will blink twice in the display
	K Off = One beep	K will blink once in the display
To Turn Ku Band On and Off
While no signal is being detected, press being detected, press and hold the City button for four seconds.	Tone	Visual Display
	Ku On = Two beeps	X and K will blink twice in the display
	Ku Off = One beep	X and K will blink once in the display

Detection

Signals Detected

The following tables 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)

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.

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

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.)
