OPERATION DETAILS
Using the Alert Filter Button
Press the ALERT FILTER button to switch between filter modes. The factory default is FILTER-NORMAL.
•
FILTER-NORMAL –
Optimized filtering for typical city or highway driving. The NORMAL mode
filters out all X band and other known radar signals commonly associated with annoying false
alerts in city and suburban areas. When this mode is selected, the screen will scroll “FILTER-
NORMAL MODE”.
•
FILTER-HIGH –
Increased filtering to reduce most false alerts, good for high-density commercial
areas. The HIGH mode is ideal when youʼre receiving frequent false alerts. Most North
American speed monitoring systems use the K or KA bands, and this mode will not adversely
affect the sensitivity to police radar/laser devices. When this mode is selected, the screen will
scroll “FILTER-HIGH MODE”.
•
FILTER-OFF –
No filtering of alert signals, ideal for open space areas. The OFF mode eliminates
the X band filter and is recommended for driving in areas where X band radar devices are still
in use. While now being phased out in most areas, X band is still used in some locations. When
this mode is selected, the screen will scroll “FILTER-OFF MODE”.
X band, occupied by police radar, is also used for other devices, such as automatic door
openers like those at supermarkets, burglar alarms, terrestrial microwave emission, and
more. In addition, other radar detectors in close proximity may falsely alert your detector.
Filtering false alerts will help you travel more comfortably.
Invisibility to VG-2 Devices
VG-2 is a technology used by speed monitoring systems to identify vehicles equipped with radar detectors
in instances and locations where they are not legal (such as in vehicles over 10,000 lbs. or in Virginia
and Washington D.C.). The VG-2 interceptors work by detecting emission frequencies (11.4~11.7 GHz)
