Scanning the area
Walk around the room clockwise or counter clockwise and probe all objects, surfaces and constructions
with the detector. Scan slowly, approaching the antenna(s) 10-20 cm to the objects.
Spy bugs can be located everywhere. Take into consideration that a hidden camera must be installed in
a way that it observes the table, negotiation area or other place of interest. Audio listening bugs must
hear the conversation clearly so they are typically placed closer to the target area and further from any
source of noise.
Despite the fact a potential bugging device can be powered from a battery, special attention should be
paid to objects and places where an AC source is available.
The bargraph levels will increase or decrease when the detector is closer to or father away from a
transmitting device.
Interference
The following appliances and equipment, when active, periodically send radio waves which may be
detected during the search:
Laptops
Tablets
Cell phones (GSM, 3G, CDMA, 4G/LTE)
Printers and other office equipment with wireless functions
Bluetooth headsets and accessories
Internet-of-Things (IoT) devices (security systems, sensors, home appliances, etc.)
Wireless alarm systems
Cordless DECT phones
Other wireless devices
Each transmitting device must be inspected carefully. It is recommended to consult with the owner/
customer in order to confirm that the device is known and friendly. When possible deactivate its
wireless function temporarily (switch off or turn on the flight mode) and continue searching.
Please note that the modern environment, especially urban areas, is full of RF sources. As a result
the detector may show a constant or periodical illumination on the bargraphs. External interference
coming from radio and TV broadcasting, cell towers, radio communications, etc. tend to cause a similar
increase of RF level near a number of windows. Signals sent by wireless and mobile devices from
neighboring premises cause an increased level near the adjacent walls or constructions. The ALARM
mode is recommended when it is necessary to reject interference.
