OPERATION
X/K Filter Modes
Recently, many new products operate on X or K band
causing nuisance alerts to radar detectors. Some of these
are radar based Traffic Monitoring Systems mounted to
poles alongside the highway and others are K Band Lane
Change Assistants and Blind Spot Detectors found on
some automobiles. The X/K Filter Mode offers multiple
levels of rejection to reduce false alerts caused by these
systems.
Ka Filter Modes
There are times when a radar detector in another vehicle,
can emit a frequency which can cause your detector to
falsely alert. The Ka Filter Modes allow you to select the
level needed for your area to minimize the occurrences of
these false alerts.
Filter Mode is the factory default setting and should
provide adequate filtering for most conditions. If you
experience excessive alerts due to radar detectors in other
vehicles, increase the Filter level. See Option Selection
Mode to change the filter settings.

Setting Saver

Setting Saver saves your personalized settings so that when the
detector is turned off and then on again, you do not have to
re-enter them.

OPERATION

Selectable Ka Band

Russia currently does not use Ka band. Having a radar
detector that scans Ka band is not necessary. See Option
Select Mode to turn on Ka band.
VG-2 Mode
See Option Select Mode to turn this feature on/off. When a
VG-2 signal is detected, the VG-2 alert is sounded and the
display flashes "VG-2". After 3 seconds the audio is canceled
and the display no longer flashes. This cycle is repeated if the
VG-2 signal is detected again.
During the period a VG-2 signal is detected, a radar signal
cannot be detected.
However, because the VG-2 alert has confirmed that a patrol
car is nearby, you are already aware of the potential for speed
monitoring and can adjust your speed accordingly. Laser
detection is not affected while a VG-2 signal is detected. (See
page 27 for more information)
