Slide the visor clip onto the top of the detector until it snaps 
into place. Clip the detector to the edge of the sun visor nearest
the windshield. 

Windshield Mounting (Not recommended for Motorcycle use)

1.

Remove the detector’s cover by pressing on the raised dots 
and pushing outward. Store the cover in a safe place.

.

Clean the selected windshield area, position the suction-cup 
mount on the windshield, and press firmly on each suction 
cup to secure it in place. 

3.

Use a screw driver or a small coin to adjust the suction-cup 
mount until the base plate is level.

Slide detector onto base plate until it snaps into place.

hil

lcannot be received until you are at or near the top. 

Warning time may be minimal (as in situation #2) since a 

strong signal is not present until you are near the crest of the 

hill. At this point, you may be nearly in the police officer’s 

line of sight. When cresting a hill, a weak initial alert followed

very quickly by a full alert is typical. This alert pattern requires

prompt attention. 

.

Police Radar signals transmitted from behind your vehicle can

be received when reflected by objects in front of you such as 

large signs, bridges and trucks. As you drive, the size and con-

figuration of these objects are constantly changing causingthe 

strength of any reflected Radar signal received to vary. A strong,

uninterrupted alert indicates the patrol car is close behind. 

If you are the target vehicle, an alert caused by instant-on Radar

will be strong and immediate. When encountered, yourunit 

responds with a three second audio/visual instant-on warning. 

Ideally, a Radar detector should only alert in the presence of 

police Radar. However, because other devices share X band 

with police Radar, false alerts sometimes occur. Generally, a 

false signal produces only a short audio and visual alert. Since

they are most often weak, it is possible to drive out of the   

signal’s range very quickly and receive only a brief alert. 

Although many times the probable source of the false signal 

can be identified (supermarket, bank, commercial building,

To conserve battery life, if no alerts or button activations occur 

for approximately one hour, the auto shut-off feature will 

engage. An obtrusive,

additional 5

about to shut off.T

returns you to highway mode; a single “beep” will confirm 

this selection. Once engaged, weak X band signals encountered

will produce no audible alert until the signal strength reaches 

a preset level. However, visual alerts are processed the instant

an X band signal is detected, keeping you quietly informed. 

Since most “false” X band signals are weak, the use of the

mode allows you to drive out of their range before they reach 

the preset level and trigger a full audio alert. In contrast,    

signals from X band traffic Radar are generally stronger and 

will exceed the preset level, causing a full X band audio alert. 

Activating the

Three microwave frequencies have been allocated by the 



(Federal Communications Commission) and are used for 
traffic Radar. They are:  

Both X and K bands are well known to motorists who have 
traveled with Radar detectors. Introduced first was X band 
Radar which became common during the 

s. In the mid 

s the lower powered, more difficult to detect K band Radar 

was introduced. In 

,  approval was given for Radar 

equipment using a third frequency, Ka. In response to this, 

 introduced the first Radar detectors capable of 

detecting X, K and Ka band signals. In late 

,  approval

was given to Wideband Ka:

Unlike Radar signals, which are highly reflective, Laser signals
have very poor reflective characteristics. Many of today’s Laser
detectors do not have the high sensitivity necessary to detect 
Laser within a large “field of view”. Your 

 Cordless 

incorporates 

’s number one rated Laser detection. Twin 

Laser ports detect energy far outside the main Laser beam—
including off-axis signals—providing the largest achievable 

° “field of view”. The alerts received by your unit are the 

same whether they are received from the front or rear. 
Note—the use of the pocket reflector will provide front Laser
detection only.

If you feel your unit is not alerting properly, keep in mind that

there are many conditions that influence the intensity or 

duration of an alert: 

.

The police are using instant-on/pulsed Radar, in which case 

no signal is transmitted until visual contact has been made 

with your vehicle. For detection of this signal, you must rely 

on reflected signals from Radar directed at traffic traveling 

ahead of you. 

.

The police Radar unit is positioned perpendicular to the road,

around a curve, or just over the crest of a hill, thus, significantly

reducing the reception range. 

.

The highway traffic between your vehicle and the police Radar

source is heavy. This blocks/reflects transmitted signals. The 

presence of several large trucks between you and the police 

Radar unit could also significantly reduce reception. 

.

Rain or humid weather conditions can absorb transmitted  

signalsbefore they reach your vehicle, again reducing detection

range. 

.

The police Radar unit is not properly tuned and is transmitting

outside the X, K or Super Wideband Ka frequency ranges.  

If you feel your unit is not properly alerting to the presence of 

Laser signals, keep in mind that rain, fog, high humidity and 

other weather conditions can affect the range that the Laser 

beam can be detected.
