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.

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.).

Exercise caution

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.
