1.3.6 Test sound player
The Test sound player is used for:
• the emission of a known acoustic signal on site (if the sound response from ST300 correlates
with the test sound, that means there is an active eavesdropping device around that sends uncoded
transmissions);
• forced triggering of voice-activated eavesdropping electronics equipped with VOX;
• locating the detected eavesdropping electronics;
• emission of a masking noise during searches;
• playback from external devices connected via line input.
For these purposes, an MP3 player is supplied with ST300. Using a flash card, the operator may
record and play custom signals that are best tailored to his search procedures.

The accumulator incorporated in the Test Sound Source is chargeable from a USB-port of a computer
through a USB/mini-USB cable.
Connect the miniUSB end of the cable to the Player (10, Fig.10), and the USB end to a computer. If
the power switch is in the
“
