Features: This highly sensitive device (TD-201) enables you to easily detect various types of hidden electronic listening devices. The device is functional, portable and comes in handy, allowing anyone to readily detect a target; a variety of bugs such as concealed microphones, or wiretapping devices which may use HF, FM, VHF or UHF band radio wave. The detector, near aimed transmitting equipment, will alert you with light (dot-meter of LED) and beep sound, which can be stopped wherever, preferred. |
|
| How to Use: Extend the antenna. Turn the volume knob toward "Large" from OFF position and all of the LED lamps of Dot-meter will go on with click sounds of the switch. Turn the knob further to set for the maximum sensitivity. After a few seconds the lamps will be turned off one by one from right side, and only the extreme left lamp (power lamp) will remain "ON" to start the operation. When the target (transmitter) or radio station is already nearby. Some of the LED lamps will remain "ON" in accordance with the strength of the waves. When there is an antenna tower of TV, FM or other radio station nearby, the detector may react to the strong electric wave, resulting in failure to detect a listening device with extremely weak electric waves. If the detector slightly reacts to FM radio waves at such places as higher stories or window. |

Transmitter consists of a body
in tiny case with antenna. Usually black vinyl wire is used for
antenna. And the length is less than 120 cm (4-feet) or so. As
you may know, the wave of transmitter is transmitted not from
the body itself, but from the antenna. Naturally, the transmitter is hidden nearby. When a wiretap is installed on the telephone, the telephone line works as antenna. And it is difficult to detect it. Carefully probe it along the line. |
