Illegal transmitters have a number of typical signs, they are:

Compact

Hidden

Handmade or produced with low quantity

Contain microphones or video cameras

Implanted inside another piece of electronic equipment

Connected to a telephone line

Connected to AC wires or with its own source of power

With an antenna

With a SIM card inserted

Regardless of the results, apply all other sweeping devises available and

carry out a physical search. Visually inspect and probe each object in the

highlighted area. Disassemble, if necessary, lamps, desktop items, tele-

phones, AC outlets, phone outlets. Inspect all power and phone lines

carefully. Open books, wardrobes, etc. Please remember, that a physical

search is a fundamental operation during a sweep.

If you find a bugging device, do not stop! You should continue the search

more carefully as eavesdroppers often install more than one device. They

may install a so called 'foolish bug' which may be easily detected and

some other well hidden devices that may have remote control and non-

standard modulation.

Checking telephone lines

When talking about phone lines we should firstly mention GSM/3G/LTE(4G)

bugging devices, which can pick up conversations from a normal landline

telephone and then transmit them via the GSM/3G/LTE(4G) network. It is

also probable that a Wi-Fi/Wi-Max or Bluetooth channel can be arranged to

transmit the information.

The Protect 1207i has been specially designed to detect all of the mentioned

kinds of telephone bugging devices.

Telephone bugs may be installed anywhere a phone line lays. It may be within

the phone set, the phone outlet, connecting box or cable. Most telephone bugs

activate only when the receiver is off-the-hook. Therefore the sweeping of

phone lines should be carried out only when the receiver is in this state.

Start checking from the phone set itself. Place the Protect 1207i near the set

and lift the receiver. Watch for an increase of the RF level (or starting of the

vibration). (Please note: It is pointless to test wireless (radio) telephones, for

they act exactly like a bugging device themselves due to the use of radio

waves. Only a physical inspection of these items is sufficient to know if they

are bugged.
