6. THE "WIRED RECEIVER" CHANNEL
The "WIRED RECEIVER" channel is intended for the detection of signals from eavesdropping
devices transmitting over electric mains and low current lines in the frequency range 0.1–180 MHz.
The detected signals are analyzed with the aid of
visual information on the screen
sounds (through headphones or the inbuilt speaker).
For connecting to electric mains, an adapter (
) is used.
For connecting to low current lines, cables (
) are used.
The mode is activated from the main menu of device, after which it is necessary to determine:
tested line type (electric mains or low current)
frequency range (0.1 – 60 MHz or 0.1 – 180 MHz).
6.1. CIRCUIT TYPE SELECTION
Upon channel activation use the keys
and
to select the circuit type ("MAINS" or "LOW
CURRENT") and press "ENTER".
A mains circuit
is connected to the electronic switch through an adapter (
). Control of
the electronic switch is disabled: only two cable cores are tested.
Low current
circuits typically comprise multiwire cabling. Eavesdropping devices can be
connected to certain paired combinations of wires. The Device is connected to those by means of
the Electronic Switch.

6.2. FREQUENCY RANGE SELECTION
Using
and
keys select one of the two frequency bands (0.1 – 60 MHZ or 0.1 – 180 MHz)
in which to search for signals, and press "ENTER". Fig.29 shows the frequency range selection
menu.
