(clicks, whistles, trills, etc.) indicate the presence of working electronic
devices near the antenna. Detection range from 5 to 30 cm.
6.2. CABLE LOCATOR MODE
Purpose - tracing cables when searching for wire listening devices.
The mode is implemented by applying a test signal (455 kHz, modulated
by dual tone low frequency signal) to the wired line and its reception by
antennas of the main unit.
Test signal is generated and fed into the cable by the generator (fig.1,
pos.2). To compensate for the attenuation of the signal, generator power
adjustment is provided.
The generator is equipped with two output connectors. If the line is
equipped with plugs or sockets of the RJ standard, an RJ45 socket is used
(fig.3, pos.7). The test signal fed to the contact #4 of that socket.
