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 – 36.000 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 alerts you when 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,
train or a stationary road hazard.
Because these microwave signals are within the K band frequency, most
conventional radar detectors 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, watch for emergency vehicles ahead of you,
on cross streets or behind you. If you see an emergency vehicle
approaching, pull over to the right side of the road and allow it to pass.
