1.3.2. RECEIVERS ANTENNAS
For the operation of receivers, a telescopic (Fig.1, item 2) and mini-antenna (Fig.1, item 9) are
used.
It is recommended to use a telescopic antenna to receive signals in the range of 20 MHz ÷ 3
GHz. It is recommended to use a mini-antenna to receive signals in the range of 2 GHz ÷ 6 GHz.
Any of these antennas can be used to receive signals in the range of 2 GHz ÷ 3 GHz.
Antennas are connected to the ANT socket on the top panel of the main unit
(Fig.3, item 5) .
1.3.3. PARAMETRIC DETECTOR ST 100P
ST 100P is a transceiver device that detects the modulation of the reflected RF sounding signal
caused by low-frequency processes in working electronic devices.
The analysis of the detected signals is carried out on the basis of the acoustic information
heard in the headphones.
1.3.4. MINI-USB CABLE
The cable (Fig.1, item 6) is used to connect the main unit to the USB port of the PC.
1.3.5. PLAYER OF THE TEST SOUND (PTS). The player is not included in the Kit.
A player is required to search for eavesdropping devices. Any portable device equipped with a
speaker (smartphone, tablet, voice recorder) can be used. Purpose of the PTS:
 creation of an acoustic signal (the correlation of this signal and the information obtained
using the ST 100 means that there is an active eavesdropping device with an unencrypted
transmission channel in the tested room);
 forced inclusion of eavesdropping devices equipped with a VOX activation system;
 localization of detected eavesdropping devices;
 creation of the "masking noise" during the search operations.
MP3 files recorded on the USB flash drive. The user can use their own files (noise in the office,
people talking, music, etc.).
1.3.6. USB FLASH DRIVE
MP3 files (for PTS), this Manual and the ST 100 software recorded on the USB flash drive.
1.4. POWER SUPPLY
The device operates on a built-in battery, the charge level of which displayed using an
indicator in the information line (Fig.6, item 3) . A fully charged battery provides 7 hours of
operation. The battery charged using a charger (Fig.1, item 5) .
To do this, insert the charger plug into the socket on the side panel (Fig.3, item 12) and
connect the charger to the 220V/50Hz.
Charging is accompanied by a red or orange glow of the charger connection indicator (Fig.3,
item 11) on the side panel of the device. Full charging time is no more than 7 hours. When
charging is complete, the indicator will turn green.
It is allowed to use the device while charging the battery. In this case, the time required to
fully charge the device increases.
