Description

Interpretation

Recommended
Response

Tone repeats slowly at
first, then speeds up
rapidly.

Probably police radar.

FULL ALERT

Tone sounds one 
time only.

Probably a false alarm, 
but possibly pulsed radar,
VG-2, or Spectre I or IV+
nearby.

Exercise caution

Tone instantly begins 
repeating rapidly.

Radar, VG-2 or Spectre I 
or IV+ nearby has been
activated suddenly.

FULL ALERT

Tone repeats slowly as you
approach a hill or bridge,
then speeds up sharply as
you reach it.

Probably police 
radar beyond the 
hill or bridge.

FULL ALERT

Tone repeats slowly 
for a short period.

Probably a false alarm.

Exercise caution

Any type of laser alert.

Laser alerts are 
never false alarms.

FULL ALERT

Any Safety Alert.

You are nearing an
emergency vehicle,
railroad crossing, 
or road hazard
(construction, 
accident, etc.).

Understanding Radar and Laser

Radar Speed Monitoring Systems

Three band frequencies have been approved by the Federal Communications
Commission (FCC) for use by speed monitoring radar equipment: 

X band

10.525 GHz

K band

24.150 GHz

Ka band

33.400 – 36.00 GHz

Your detector detects signals in all three radar bands, plus Ku band (13.435 GHz),
which is an approved frequency used in parts of Europe and Asia.

VG-2 and Spectre I & IV+

VG-2 

and

Spectre I & IV+ 

are radar detector detectors (RDDs) that work by

detecting low-level signals emitted by most radar detectors. Your detector
does not emit signals that can be spotted by VG-2 and Spectre I RDDs.
However, your detector 

can

be spotted by Spectre IV+ RDDs. Your unit

detects signals from these or similar devices and will alert you when such 
a device is in use near your vehicle.

Safety Alert Traffic Warning System

FCC-approved 

Safety Alert

transmitters emit microwave radar signals that

indicate the presence of a safety-related concern. Depending on the frequency
of the signal emitted, it can indicate a speeding emergency vehicle or train, 
or a stationary road hazard. 

Because these microwave signals are within the K band frequency, most
conventional radar detectors will detect Safety Alert signals as standard 
K band radar. Your detector, however, is designed to differentiate between
standard K band and Safety Alert signals, and give separate alerts for each.

Safety Alert technology is relatively new. Safety Alert transmitters can 
be found in limited numbers in all 50 states, but the number is growing.
Depending on your location, you may not receive these alerts regularly 
and may often encounter emergency vehicles, trains and road hazards 
without being alerted. As the number of transmitters increases, 
these alerts will become more common. 

When you receive such an alert, please watch for emergency vehicles ahead 
of you, on cross streets and behind you. If you see an emergency vehicle
approaching, please pull over to the right side of the road and allow it to pass.

Instant-On Detection

NOTE

You should take appropriate action immediately 
whenever an instant-on alert is given.
