notice the “

” or “” indicator remains dim to confirm your 

unit is receiving power. To return to a full bright setting, 
press the drk button a third time; two “beeps” confirm this 
selection. Use of the drk button does not affect audio alerts.
Important—if you press the the 

Your unit has been preset at the factory to provide continuous 
audio alerts at your selected audio level. This standard setting 
is often preferred when background noise in a vehicle is loud. 

To engage automatic muting, press the 

 button once 

when the unit is receiving no alerts. A single “beep” confirms 
automatic mute mode has been engaged. The alert pattern 
when this mode is activated, consists of an initial audio warning
at your selected audio level followed by continued warning at a 
lower audio level. If a new signal is detected within 5 seconds of 
the previously detected signal, while in automatic mute mode, 
only the lower level audio warning will be heard. The automatic 
mute mode enables you to conveniently monitor extended 
encounters without having to manually mute or adjust the 
volume setting. To return to the continuous audio alert pattern,
press the 

 button a second time (providing no alerts are 

being detected). Two “beeps” confirm you have cancelled auto-
matic mute mode.

Regardless of the 

 mode selected (continuous or automatic

mute), the audio alerts can be completely muted by pressing 
the 

 button during an alert. Once the alert has passed, the

unit will revert to the previous aud setting. 

The 

 mode has been designed to effectively reduce un-

wanted audio alerts caused by intrusion alarms, door openers,
and other devices which share X band with police Radar—
without reducing sensitivity. Signals from non-police Radar 





etc.), caution is advised until the source can be confirmed. 
The X band alert pattern caused by a non-police source can 
look like the initial alert produced by actual police Radar. For 
this reason appropriate action is required any time an alert 
is received. 

When Laser is detected, the 4-led display will “ramp” from 
right to left (opposite pattern from that of Radar detection).
This illumination pattern occurs rapidly and is coupled with 
the flashing of the red Laser 

 () and the Laser audio alert.

If a vehicle is a long distance from the source of Laser pulses,

fewer pulses will generally be received. The closer the vehicle 
is to the source of Laser pulses, the greater the likelihood of 
receiving a steady stream of Laser pulses. The reason for this 
is the aiming stability of the Laser gun and the fact that it is 
impossible to hold the gun absolutely still. Any movement of 
the gun results in motion of the beam at the target. The further
the target, the greater the displacement of the beam and the 
shorter the dwell time of the beam at the target point. There-
fore, there is the possibility of receiving only a few Laser pulses.

Due to these characteristics, all Laser alerts received from 

your unit should be taken seriously.

Whenever your express Cordless detects signals from the 
Interceptor vg-2 (Radar Detector Detector), the vg-2 Guard

®

Feature alerts (vg-2 Guard

®

must be selected on in Selectable

Features, see page 9). A distinct, 3-second audio warning
coupled with the flashing of the first and fourth leds in the 4-
led

display confirm activation of the vg-2 Guard

®

. The led

flashing continues for as long as vg-2 Guard

®

is activated.

During the vg-2 alert your unit does not detect Radar or sws

™

signals. However, the presence of the Interceptor vg-2 indi-
cates that traffic is being monitored and your speed should be
adjusted accordingly.

System

™

.The concept behind this system is to warn motorists 

of potential road hazards by employing Safety Warning System

™

transmitting devices in areas such as construction zones, 

accidents sites and detours. Because these sws

™

transmitters 

operate within the 



z

portion of the K band frequency, 

their signals are detected by your 

Cordless.

   

The alerts provided by your unit are affected both by the type 

of transmission (continuous wave or instant-on), and the 

position of the Radar source. Generally, when you drive closer

to a Radar source, the intensity of the received signal increases,

resulting in the flashing of a higher number in the

-dis-

play and a corresponding increase in the audio alert rate. 

Described below are five common types of Radar encounters 

and the alerts you will typically receive. 



.

Since Radar signals travel in a straight line, this Radar 

encounter potentially offers maximum warning range. Once 

the signal is received, the initial warning consists of the X,    

K or Super Wideband Ka audio and visual alerts and the 

simultaneous flashing of digit #1

or digit #2

in the 4-led

display.

The actual digit displayed will depend upon the strength of 



. 

Consider occupant safety when selecting a mounting location.

Choose a location where the unit will not be hazardous in 

case of an accident. 

. 

For optimum detection, position your unit with a clear,    

unobstructed view of the road from thefront and rear.

. 

Do not allow the unit to make contact with the windshield. 

This will eliminate unnecessary vibration. 

. 

Avoid placing your unit in direct sunlight. During the summer,

interior temperatures of an enclosed vehicle can sometimes 

reach temperatures that will cause premature aging of the unit.

. 

Your detector is not waterproof; exposure to water may cause

damage. 

. 

Select an area that is relatively level, clean and 

dry. Adhere 

the

soft portion of the enclosed hook and loop fastener to this area

and the corresponding hard portion to the bottom of your unit. 

. 

Fasten unit to dash by placing hook and loop pieces together.

.

The visor clip is fully 

assembled. To assemble 

the windshield bracket, 

follow this diagram.

cover by pressing on the raised dots and pushing 

outward. Store the cover in a safe place.

 

Do not mount your unit directly behind windshield wipers or 
mirrored sunscreens which block Radar and Laser signals 
and substantially reduce warning range. Unlike “after market”
mirrored sun-screens, regular tinted glass does not affect 
Radar reception.  

Radar signals are also reflected by the “heated windshields”

known as Instaclear

®

and ElectriClear

®

available as an option 

on some vehicles. This type of windshield makes any dash, 
visor or windshield mounted detector ineffective. (If in 
doubt, check with an appropriate dealership to see if this 
applies to your vehicle.) 

To achieve optimum performance, regardless of which 

mounting position you choose, follow these basic steps on the
following page: 



the signal received. As the strength of the Radar signal 
increases, the audio alert becomes more rapid and the flashing
of digit #3 or #4 or the flashing of all leds (left to right) will 
occur. This indicates a maximum signal strength. Assuming 
the Radar signal remains uninterrupted, the audible and visual
alerts will clearly indicate a “weak” signal becoming stronger 
as you drive closer to the Radar source. Remember, when the 
police Radar source is moving toward you, the Radar signal 
strength will increase much more rapidly than if you 
are approaching a stationary source. 

.

Under this circumstance, reaction time is considerably 
reduced. Since the Radar signals are transmitted across your 
line of travel, there is generally no signal available to receive 
until you are relatively close to the source. Once an alert is 
received, expect the strength of the signal to increase very 
quickly. Advanced warning in this situation may be reduced. 

.

Radar signals travel in a straight line and do not pass through
earth. Consequently, police Radar aimed at the crest of a steep
