Low Battery Warning
Three warnings alert you as battery power diminishes. The
level of battery life remaining is confirmed by the following:
. ‒ hours battery life remaining: the “” (battery)  flashes
once followed by the green “”  or amber “”  flashing
three times. This flashing pattern will continue for two hours.
. Less than  hours battery life remaining: the green “” 
or amber “”  flashes once followed by the red “” 
flashing three times.
. Final warning: red “”  flashes continuously coupled with
a loud, obtrusive audible warning, confirming a new battery
is required.
Please note—we advise you take  Cordless indoors
after use during cold weather. In some circumstances, the “”
(battery)  may flash if the battery is extremely cold. Once
the battery warms up however, this situation will be corrected.
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 configuration of these objects are constantly changing causing the
strength of any reflected Radar signal received to vary. A strong,
uninterrupted alert indicates the patrol car is close behind.
Instant-On Radar
If you are the target vehicle, an alert caused by instant-on Radar
will be strong and immediate. When encountered, your unit
responds with a three second audio/visual instant-on warning.

Typical False Alert (Radar)
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.

Conditions that Affect Radar Alerts
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.


sources are frequently encountered in urban and suburban
areas, making use of this mode ideal in these areas.
Pressing the  button once engages the  mode which
is confirmed by the flashing amber city  labeled “” and a
single audio “beep”. Pressing the  button a second time
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  mode will not change Super Wideband
Ka, K or instant-on X band Radar alert patterns.
Note—the cty mode has no effect on the reception of Laser,
sws™ or vg-2 signals.
Reset to Factory Settings
You can reset your unit to factory settings for volume, ,

Safety Warning System™ (sws™)—What is it?
The Radio Association Defending Airwave Rights, Inc.
(.....) conceived and developed the Safety Warning
Total Tracking Laser™ (ttl™)
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.
Three Radar Frequencies
Three microwave frequencies have been allocated by the 
(Federal Communications Commission) and are used for
traffic Radar. They are:
X band: . z
K band: . z
Super Wideband Ka: . z to . z
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: . z to . z. Once again,
 responded with Wideband Ka detection. Today, 
Cordless detects the complete Super Wideband Ka frequency
allotted for police monitoring—. to . z.

General Guidelines
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:
Instaclear is a registered trademark of the Ford Motor Company.
ElectriClear is a registered Trademark of Libbey, Owens, Ford, and Delco-Remy.

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.

Continuous Audio Alert Pattern
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.
Automatic Mute Audio Alert Pattern
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 automatic mute mode.
Manual Muting of Audio Alerts
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.

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.
Laser Alerts
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. Therefore, 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.
vg-2 Guard® Alert
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 4led 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 indicates that traffic is being monitored and your speed should be
adjusted accordingly.
Note—activation of - Guard® does not affect detection of
Laser signals.

Pocket Reflector
. Remove the detector’s cover by pressing on the raised dots
and pushing outward. Store the cover in a safe place.
. Position the reflector onto the unit as per the diagram and
slide the reflector on to the detector until it snaps into place.
. Place the detector in pocket as pictured.
Radar Alerts
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

Radar Alerts
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 - display 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.
Note–during the initial three seconds of an alert, the 

vg-2 Guard® Alert
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 4led 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 indicates that traffic is being monitored and your speed should be
adjusted accordingly.
Note—activation of - Guard® does not affect detection of
Laser signals.

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.
Laser Alerts
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. Therefore, 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.

Automatic Mute Audio Alert Pattern
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

volume setting. To return to the continuous audio alert pattern,
press the  button a second time (providing no alerts are

Manual Muting of Audio Alerts
Regardless of the  mode selected (continuous or automatic

General Guidelines
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.

Conditions that Affect Radar Alerts
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.

Typical False Alert (Radar)
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.

Three Radar Frequencies
Three microwave frequencies have been allocated by the 
(Federal Communications Commission) and are used for
traffic Radar. They are:
X band: . z
K band: . z
Super Wideband Ka: . z to . z
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: . z to . z. Once again,
 responded with Wideband Ka detection. Today, 
Cordless detects the complete Super Wideband Ka frequency
allotted for police monitoring—. to . z.

Total Tracking Laser™ (ttl™)
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.

Pressing the  button once engages the  mode which
is confirmed by the flashing amber city  labeled “” and a
single audio “beep”. Pressing the  button a second time
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.

Radar Alerts
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 - display 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.
Note–during the initial three seconds of an alert, the 
will illuminate solid to provide clear indication of the alert
received before entering flashing mode.

of potential road hazards by employing Safety Warning System™
transmitting devices in areas such as construction zones,

their signals are detected by your  Cordless.

coupled with the flashing of the first and fourth leds in the 4led 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™

adjusted accordingly.

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.
Laser Alerts
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. Therefore, 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.

General Guidelines
Do not mount your unit directly behind windshield wipers or

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”

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

Conditions that Affect Radar Alerts
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.

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

Three Radar Frequencies
Three microwave frequencies have been allocated by the 
(Federal Communications Commission) and are used for
traffic Radar. They are:
X band: . z
K band: . z
Super Wideband Ka: . z to . z
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: . z to . z. Once again,
 responded with Wideband Ka detection. Today, 
Cordless detects the complete Super Wideband Ka frequency
allotted for police monitoring—. to . z.

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.

Total Tracking Laser™ (ttl™)
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.

Pressing the  button once engages the  mode which
is confirmed by the flashing amber city  labeled “” and a
single audio “beep”. Pressing the  button a second time
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  mode will not change Super Wideband
Ka, K or instant-on X band Radar alert patterns.

Three Radar Frequencies
Three microwave frequencies have been allocated by the 
(Federal Communications Commission) and are used for
traffic Radar. They are:
X band: . z
K band: . z
Super Wideband Ka: . z to . z
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: . z to . z. Once again,
 responded with Wideband Ka detection. Today, 
Cordless detects the complete Super Wideband Ka frequency
allotted for police monitoring—. to . z.

Total Tracking Laser™ (ttl™)
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.

Pressing the  button once engages the  mode which
is confirmed by the flashing amber city  labeled “” and a
single audio “beep”. Pressing the  button a second time
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  mode will not change Super Wideband
Ka, K or instant-on X band Radar alert patterns.

Radar Alerts
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 - display 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.
Note–during the initial three seconds of an alert, the 
will illuminate solid to provide clear indication of the alert
received before entering flashing mode.
Stationary or moving Radar, straight ahead aimed in your

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.

vg-2 Guard® Alert
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 4led 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 indicates that traffic is being monitored and your speed should be
adjusted accordingly.
Note—activation of - Guard® does not affect detection of
Laser signals.

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.
Laser Alerts
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. Therefore, 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.
Safety Warning System® (sws™)
 Cordless detects encoded signals from sws™
transmitters and provides distinct alerts for: Highway
Construction/Maintenance, Highway Hazard Zones, Weather

General Guidelines
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.

Auto Shut-Off
To conserve battery life, if no alerts or button activations occur
for approximately one hour, the auto shut-off feature will
engage. An obtrusive,  second audio/visual warning and an
additional 5 second visual warning will confirm the unit is
about to shut off. To defeat auto shut-off, press any button
during this 8 second warning.
Low Battery Warning
Three warnings alert you as battery power diminishes. The
level of battery life remaining is confirmed by the following:
. ‒ hours battery life remaining: the “” (battery)  flashes
once followed by the green “”  or amber “”  flashing
three times. This flashing pattern will continue for two hours.
. Less than  hours battery life remaining: the green “” 
or amber “”  flashes once followed by the red “” 
flashing three times.
. Final warning: red “”  flashes continuously coupled with
a loud, obtrusive audible warning, confirming a new battery
is required.
Please note—we advise you take  Cordless indoors
after use during cold weather. In some circumstances, the “”
(battery)  may flash if the battery is extremely cold. Once
the battery warms up however, this situation will be corrected.

The jack located closest to the control panel of the unit is
used to connect the external earphone speaker. The earphone
speaker is mounted inside your helmet and will ensure you
hear all audible alerts.

Conditions that Affect Radar Alerts
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.

Typical False Alert (Radar)
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.

Three Radar Frequencies
Three microwave frequencies have been allocated by the 
(Federal Communications Commission) and are used for
traffic Radar. They are:
X band: . z
K band: . z
Super Wideband Ka: . z to . z
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: . z to . z. Once again,
 responded with Wideband Ka detection. Today, 
Cordless detects the complete Super Wideband Ka frequency
allotted for police monitoring—. to . z.

Total Tracking Laser™ (ttl™)
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.

Pressing the  button once engages the  mode which
is confirmed by the flashing amber city  labeled “” and a
single audio “beep”. Pressing the  button a second time
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  mode will not change Super Wideband
Ka, K or instant-on X band Radar alert patterns.
Note—the cty mode has no effect on the reception of Laser,

Radar Alerts
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 - display 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.
Note–during the initial three seconds of an alert, the 
will illuminate solid to provide clear indication of the alert
received before entering flashing mode.
Stationary or moving Radar, straight ahead aimed in your

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.

vg-2 Guard® Alert
Whenever your express Cordless detects signals from the

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 4led 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 indicates that traffic is being monitored and your speed should be
adjusted accordingly.
Note—activation of - Guard® does not affect detection of
Laser signals.

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.
Laser Alerts
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. Therefore, 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.
Safety Warning System® (sws™)
 Cordless detects encoded signals from sws™
transmitters and provides distinct alerts for: Highway

Automatic Mute Audio Alert Pattern
To engage automatic muting, press the  button once

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

General Guidelines
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:

increases, the audio alert becomes more rapid and the flashing

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

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

Continuous Audio Alert Pattern
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.
Automatic Mute Audio Alert Pattern
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 automatic mute mode.
Manual Muting of Audio Alerts
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.
If you experience a problem with your unit that is not covered
in the previous outline please call, Monday to Friday,  –

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.
Laser Alerts
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. Therefore, 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.
vg-2 Guard® Alert
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 4led 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 indicates that traffic is being monitored and your speed should be
adjusted accordingly.
Note—activation of - Guard® does not affect detection of
Laser signals.

. Position the reflector onto the unit as per the diagram and

. Place the detector in pocket as pictured.
Radar Alerts
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 - display and a corresponding increase in the audio alert rate.

and the alerts you will typically receive.

Low Battery Warning
Three warnings alert you as battery power diminishes. The
level of battery life remaining is confirmed by the following:
. ‒ hours battery life remaining: the “” (battery)  flashes
once followed by the green “”  or amber “”  flashing
three times. This flashing pattern will continue for two hours.
. Less than  hours battery life remaining: the green “” 
or amber “”  flashes once followed by the red “” 
flashing three times.
. Final warning: red “”  flashes continuously coupled with
a loud, obtrusive audible warning, confirming a new battery
is required.
Please note—we advise you take  Cordless indoors
after use during cold weather. In some circumstances, the “”
(battery)  may flash if the battery is extremely cold. Once
the battery warms up however, this situation will be corrected.
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 configuration of these objects are constantly changing causing the
strength of any reflected Radar signal received to vary. A strong,
uninterrupted alert indicates the patrol car is close behind.
Instant-On Radar
If you are the target vehicle, an alert caused by instant-on Radar
will be strong and immediate. When encountered, your unit
responds with a three second audio/visual instant-on warning.

Typical False Alert (Radar)
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.

Conditions that Affect Radar Alerts
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.


sources are frequently encountered in urban and suburban
areas, making use of this mode ideal in these areas.
Pressing the  button once engages the  mode which
is confirmed by the flashing amber city  labeled “” and a
single audio “beep”. Pressing the  button a second time
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  mode will not change Super Wideband
Ka, K or instant-on X band Radar alert patterns.
Note—the cty mode has no effect on the reception of Laser,
sws™ or vg-2 signals.

Safety Warning System™ (sws™)—What is it?
The Radio Association Defending Airwave Rights, Inc.
(.....) conceived and developed the Safety Warning
Total Tracking Laser™ (ttl™)
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.
Three Radar Frequencies
Three microwave frequencies have been allocated by the 
(Federal Communications Commission) and are used for
traffic Radar. They are:
X band: . z
K band: . z
Super Wideband Ka: . z to . z
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: . z to . z. Once again,
 responded with Wideband Ka detection. Today, 
Cordless detects the complete Super Wideband Ka frequency
allotted for police monitoring—. to . z.

General Guidelines
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:
Instaclear is a registered trademark of the Ford Motor Company.
ElectriClear is a registered Trademark of Libbey, Owens, Ford, and Delco-Remy.

Post-Warranty Service
The following arrangements apply if the one-year warranty
period has expired or you are not able to provide a copy of
your dated sales receipt indicating purchase within the last
twelve months.

Service and follow steps  through (b) outlined in that section.
Enclose a check with your unit for $  or $ Canadian to

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.

Continuous Audio Alert Pattern
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.
Automatic Mute Audio Alert Pattern
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 automatic mute mode.
Manual Muting of Audio Alerts
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.
If you experience a problem with your unit that is not covered
in the previous outline please call, Monday to Friday,  –

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.
Laser Alerts
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. Therefore, 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.
vg-2 Guard® Alert
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 4led 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 indicates that traffic is being monitored and your speed should be
adjusted accordingly.
Note—activation of - Guard® does not affect detection of
Laser signals.

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

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 the front 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.

Continuous Audio Alert Pattern
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.
Automatic Mute Audio Alert Pattern
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 automatic mute mode.
Manual Muting of Audio Alerts
Regardless of the  mode selected (continuous or automatic

General Guidelines
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.

Conditions that Affect Radar Alerts
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.

Ideally, a Radar detector should only alert in the presence of
police Radar. However, because other devices share X band

Three Radar Frequencies
Three microwave frequencies have been allocated by the 
(Federal Communications Commission) and are used for
traffic Radar. They are:
X band: . z
K band: . z
Super Wideband Ka: . z to . z
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: . z to . z. Once again,
 responded with Wideband Ka detection. Today, 
Cordless detects the complete Super Wideband Ka frequency
allotted for police monitoring—. to . z.

Total Tracking Laser™ (ttl™)
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.

Pressing the  button once engages the  mode which
is confirmed by the flashing amber city  labeled “” and a
single audio “beep”. Pressing the  button a second time
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  mode will not change Super Wideband
Ka, K or instant-on X band Radar alert patterns.

Radar Alerts
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 - display 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.
Note–during the initial three seconds of an alert, the 
will illuminate solid to provide clear indication of the alert
received before entering flashing mode.
Stationary or moving Radar, straight ahead aimed in your

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.

vg-2 Guard® Alert
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 4led 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 indicates that traffic is being monitored and your speed should be
adjusted accordingly.
Note—activation of - Guard® does not affect detection of
Laser signals.

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.
Laser Alerts
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. Therefore, 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.
Safety Warning System® (sws™)
 Cordless detects encoded signals from sws™
transmitters and provides distinct alerts for: Highway
Construction/Maintenance, Highway Hazard Zones, Weather
Related Hazards, Emergency/Slow Moving Vehicles and
Travel/Convenience Information.

For optimum detection, position your unit with a clear,
unobstructed view of the road from the front 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.

Continuous Audio Alert Pattern
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.
Automatic Mute Audio Alert Pattern
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

General Guidelines
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.

Conditions that Affect Radar Alerts
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.

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: . z to . z. Once again,
 responded with Wideband Ka detection. Today, 
Cordless detects the complete Super Wideband Ka frequency
allotted for police monitoring—. to . z.

Total Tracking Laser™ (ttl™)
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.

Pressing the  button once engages the  mode which
is confirmed by the flashing amber city  labeled “” and a
single audio “beep”. Pressing the  button a second time
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  mode will not change Super Wideband

Auto Shut-Off
To conserve battery life, if no alerts or button activations occur
for approximately one hour, the auto shut-off feature will
engage. An obtrusive,  second audio/visual warning and an
additional 5 second visual warning will confirm the unit is
about to shut off. To defeat auto shut-off, press any button
during this 8 second warning.
Low Battery Warning
Three warnings alert you as battery power diminishes. The
level of battery life remaining is confirmed by the following:
. ‒ hours battery life remaining: the “” (battery)  flashes
once followed by the green “”  or amber “”  flashing
three times. This flashing pattern will continue for two hours.
. Less than  hours battery life remaining: the green “” 
or amber “”  flashes once followed by the red “” 
flashing three times.
. Final warning: red “”  flashes continuously coupled with
a loud, obtrusive audible warning, confirming a new battery
is required.
Please note—we advise you take  Cordless indoors
after use during cold weather. In some circumstances, the “”

Conditions that Affect Radar Alerts
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.

Typical False Alert (Radar)
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.

Radar Alerts
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 - display 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.
Note–during the initial three seconds of an alert, the 

received before entering flashing mode.

transmitting devices in areas such as construction zones,
accidents sites and detours. Because these sws™ transmitters

their signals are detected by your  Cordless.

vg-2 Guard® Alert
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 4led 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 indicates that traffic is being monitored and your speed should be
adjusted accordingly.
Note—activation of - Guard® does not affect detection of
Laser signals.

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.
Laser Alerts
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. Therefore, 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.
Safety Warning System® (sws™)
 Cordless detects encoded signals from sws™
transmitters and provides distinct alerts for: Highway
Construction/Maintenance, Highway Hazard Zones, Weather

Automatic Mute Audio Alert Pattern
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

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

General Guidelines
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.

Conditions that Affect Radar Alerts
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.

Three Radar Frequencies
Three microwave frequencies have been allocated by the 
(Federal Communications Commission) and are used for
traffic Radar. They are:
X band: . z
K band: . z
Super Wideband Ka: . z to . z
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: . z to . z. Once again,
 responded with Wideband Ka detection. Today, 
Cordless detects the complete Super Wideband Ka frequency
allotted for police monitoring—. to . z.

Total Tracking Laser™ (ttl™)
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.

Pressing the  button once engages the  mode which
is confirmed by the flashing amber city  labeled “” and a
single audio “beep”. Pressing the  button a second time
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  mode will not change Super Wideband
Ka, K or instant-on X band Radar alert patterns.
Note—the cty mode has no effect on the reception of Laser,

Radar Alerts
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 - display 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.
Note–during the initial three seconds of an alert, the 
will illuminate solid to provide clear indication of the alert
received before entering flashing mode.
Stationary or moving Radar, straight ahead aimed in your
direction.
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.

vg-2 Guard® Alert
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 4led 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 indicates that traffic is being monitored and your speed should be
adjusted accordingly.
Note—activation of - Guard® does not affect detection of
Laser signals.

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.
Laser Alerts
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. Therefore, 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.
Safety Warning System® (sws™)
 Cordless detects encoded signals from sws™
transmitters and provides distinct alerts for: Highway
Construction/Maintenance, Highway Hazard Zones, Weather
Related Hazards, Emergency/Slow Moving Vehicles and

General Guidelines
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.)

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. Therefore, 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.
vg-2 Guard® Alert
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 4led 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 indicates that traffic is being monitored and your speed should be
adjusted accordingly.
Note—activation of - Guard® does not affect detection of
Laser signals.

. Remove the detector’s cover by pressing on the raised dots
and pushing outward. Store the cover in a safe place.
. Position the reflector onto the unit as per the diagram and
slide the reflector on to the detector until it snaps into place.
. Place the detector in pocket as pictured.
Radar Alerts
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 - display 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.
Note–during the initial three seconds of an alert, the 

received before entering flashing mode.

flashing three times.
. Final warning: red “”  flashes continuously coupled with
a loud, obtrusive audible warning, confirming a new battery
is required.
Please note—we advise you take  Cordless indoors
after use during cold weather. In some circumstances, the “”

the battery warms up however, this situation will be corrected.
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 configuration of these objects are constantly changing causing the
strength of any reflected Radar signal received to vary. A strong,
uninterrupted alert indicates the patrol car is close behind.
Instant-On Radar
If you are the target vehicle, an alert caused by instant-on Radar
will be strong and immediate. When encountered, your unit

Typical False Alert (Radar)
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.

Conditions that Affect Radar Alerts
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.


sources are frequently encountered in urban and suburban
areas, making use of this mode ideal in these areas.
Pressing the  button once engages the  mode which
is confirmed by the flashing amber city  labeled “” and a
single audio “beep”. Pressing the  button a second time
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  mode will not change Super Wideband
Ka, K or instant-on X band Radar alert patterns.
Note—the cty mode has no effect on the reception of Laser,
sws™ or vg-2 signals.

Safety Warning System™ (sws™)—What is it?
The Radio Association Defending Airwave Rights, Inc.
(.....) conceived and developed the Safety Warning
Total Tracking Laser™ (ttl™)
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.
Three Radar Frequencies
Three microwave frequencies have been allocated by the 
(Federal Communications Commission) and are used for
traffic Radar. They are:
X band: . z
K band: . z
Super Wideband Ka: . z to . z
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: . z to . z. Once again,
 responded with Wideband Ka detection. Today, 
Cordless detects the complete Super Wideband Ka frequency
allotted for police monitoring—. to . z.
