UNDERSTANDING RADAR & 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.
VG-2 and Spectre
VG-2 and Spectre 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, but does
detect VG-2 and Spectre 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 near full strength.
You should take appropriate
action immediately whenever
an alert is given.
Bee III Pop Detection
Your detector is designed to detect single
pulse mode radars. These radars are
designed to have a low probability of
detection. You should note that these radar
guns have a much shorter range while in
this mode.
