The device is destined for operational measurements as far as detection and location of the bugs are concerned. It consists of main control-measurement unit and converters kit. The devices can be used in such modes:
- High frequency detector - frequency meter;
- Scanning wires analyser
- Infrared detector
- Low frequency magnetic field detector
- Vibro-acoustic receiver
- Acoustic receiver
- Wired acoustic receiver

The process of switching into other operation mode is made automatically (connection of proper converter is necessary).
Information is displayed on LCD; acoustic control is realized by special headphones or the speaker that is built-in.
Device control takes place by membrane keyboard (16 keys).
The detector enables conversion of the low frequency received signals in the oscillograph mode, or spectrum analyser together with picturing of the variables.
