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
VG-2
VG-2 is a Radar Detector Detector (RDD) that works by detecting low-level signals emitted by
most radar detectors. Your detector does not emit signals that can be detected by VG-2, but
does detect VG-2 signals and will alert you when a VG-2 device is in use near your vehicle.
While no signal is being detected, press and hold the Dim button for four seconds.
The factory setting for VG-2 alerts is Off.
