K9 x1, Ka1 x9, Ka9 x2 – Beltronics RX45 User Manual

ThreatDisplay
Beltronics’s exclusive ThreatDisplay option 
is an advanced display for experienced 
detector users. Please use the RX45 for a 
few weeks to get fully familiar with its 
other features before using ThreatDisplay.
 
To use the ThreatDisplay instead of the
standard bar graph signal strength meter, 
you must select Meter THT in the RX45’s 
Preferences (see pages 8-12).
 
ThreatDisplay simultaneously tracks
multiple radar signals. It shows you detailed 
information on multiple radar signals and 
their signal strength.
 
ThreatDisplay can help you spot a
change in your normal driving 
environment; for example, a traffic radar 
unit being operated in an area where there 
are normally other signals present.
A few more examples will help you
better see how the ThreatDisplay works.
K9 X1
Here Threat Display shows a strong 
K-band signal, and a weak X-band 
signal.
Ka1 X9
Here Threat Display shows a weak 
Ka-band signal, and a strong X-band 
signal.
ThreatDisplay Details
 
The band designators (X, K, Ku, Ka) will
stay on the display for a few seconds after 
the signal has passed. This allows you to see 
what the unit detected, even on very brief 
signals.
 
However, the numeric values,
representing signal strength, continuously 
change (several times a second) to give you 
a continuous view of the signal strength of 
all radar signals present.
TechDisplay
The RX45’s TechDisplay option is also 
designed for the advanced detector user. In 
this mode, it will display the actual numeric 
radar frequency being received
K 24.150
Display shows a K-band signal at 24.150 
GhZ.
Ka 34.700
Display shows a Ka-band signal at 34.700 
GhZ.
X 10.525
Display shows a X-band signal at 10.525 
GhZ.
NOTE: Even long-time detector
users will require a significant
amount of time to get familiar with
this new level of information.
The ThreatDisplay is actually a
miniature spectrum analyzer. It shows what 
band each signal is, and its signal strength. 
Ka9 X2
Above is the ThreatDisplay if the RX45 
was detecting a strong Ka-band and a 
weak X-band signal.
 
As you can see, there are numeric
values (1-9) after each band designator. 
Each number shows a relative signal 
strength for each signal being detected.
