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.

Radar Speed Monitoring Systems

Three (3) 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 (3) 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.
