EXPLANATORY NOTES:
Radar frequency bands: Dierent
radar bands are used to measure
speed, most often Ka, K, X, or newer
MultaRadars and GATSO Radars
that have extremely low transmit
power and are hard to detect.
Dierent bands and frequencies are
used in each country, it is therefore
necessary to have the detector set up
correctly for each country.
• Ka - One of the most commonly
used radar band for speed
measuring.
• K - The most widely used band at
all, is comonnly used for automatic
doors at petrol stations and shops,
adaptive cruise control, etc. Devices
operating in the K band cause false
alerts, so their quality filtration is
essential.
• X – Less and less used band, used
only in some Eastern European
countries.
• CD/CT MultaRadars - Modern
radars used in Austria, Iceland,
Netherlands, Poland, Portugal,
Slovakia, Spain.
• GATSO radars - Another modern
radars, they can be stationary or
mobile. They are used in Belgium,
France, Finland, Great Britain,
Lithuania, Netherlands, Slovenia.
They are divided into RT2/RT3/RT4
- a higher number means a more
modern version. The detection of
these radars is possible only by the
latest and most sensitive detector.
Narrow: Narrowed bands. Frequency
of a specic part of aband is detected
in the narrowed band to increase
sensitivity and eliminate false alerts.
Wide: Broadband mode, on the
other hand, searches for example
the entire Ka band from 33.4 GHz
to 36.0 GHz. Use this setting only if
absolutely necessary, as it shortens
the detection distance and increases
the number of false alerts.
Filters and false alerts: For the
correct functioning of the detector, it
is essential to lter unwanted radar
signals from sources other than
police radars (eg adaptive cruise
control of modern vehicles), so that
the detector reports only police
radars. The lter settings are further
described on page 7 in the manual
(ALERTS NOTIFICATION SETTINGS).
Laser measurement: Laser speed
measurement is based on emitting
an ultra narrow and short-time beam
of electromagnetic light at the level
of infrared radiation. The signal is
transmitted for a very short time at
a specic place (usually car’s licence
plate) and therefore, it is almost
imposible to detect it in advance. The
only eective protection against laser
speed measurement is an additional
active laser system.
GPS: The GPS antenna also detects
measurements that do not emit any
signals. These include section speed
cameras, stationary speed cameras
(induction loops) or “red-light
cameras”. We keep adding everything
continuously to the GPS database of
stationary threats - all you have to do
is keep the detector updated.
