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 1 nearby

Exercise caution

Tone instantly begins 
repeating rapidly.

Radar, VG-2, or Spectre 1
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 
or Strobe Alert.

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

Exercise caution

Understanding Radar and Laser

Radar Speed Monitoring Systems

Four 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

Ku band

13.435 GHz

Your detector detects signals in all four radar bands.

VG-2 and Spectre 1

VG-2 and Spectre 1 are “detector detectors” that work by detecting low-level
signals emitted by most radar detectors. Your detector does not emit signals
that can be detected by VG-2 or Spectre 1, but does detect VG-2 and Spectre 1
signals and will alert you when a device is in use near your vehicle, if you 
so choose.

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

Your detector is designed to detect Instant-On speed monitoring signals,
which can suddenly appear at full strength.

NOTE

You should take appropriate action 

immediately whenever an instant-on alert is given.
