With the unit set in
TRAVEL
mode, the number of Radar
frequencies totals 10. To see these frequencies, access Selectable
Features.
(see page 13).
In addition,
TRAVEL
mode presents the
actual frequency detected followed by the regular alarm. Based
on the alert pattern received
(see page 17)
, you can judge which
frequencies in your area of travel you know to be “false” and
which are true traffic Radar. This allows you to turn OFF any
frequency which you know to be generating false alerts.
(You can
also turn off a frequency if you know it is not used in your area of
travel.)
For example, because other devices are shared with
traffic radar
(see Typical False Alerts, page 20)
you may notice a
constant X Band signal (9.9 GHz) alarming in a specific area you
know to be a false alert. By displaying the actual frequency, you
are able to determine if you want to turn that particular
frequency OFF in Selectable Features.

area of travel, you can turn any of the frequencies off.
Note: It is important to know what frequencies are used in your
area of travel. If you encounter excessive falsing on X, K or Ka
Bands when operating your unit in
TRAVEL
mode, you can
engage the City All mode in Selectable Features or turn the
offending Band or Bands off in Selectable Features. (see page 13).
If excessive falsing occurs specifically on Super Wideband Ka,
select the specific Ka Narrow frequency or frequencies used in your
area of travel.
bel
990
allows you to engage one, two or three
specific Ka Narrow frequencies (34.0 GHz, 34.3 GHz, 34.7 GHz).
