Please note this device does not use RF frequency during operation.
Dictaphone counter measures voice recorder audio stopper
(Ultrasonic sound stopping with total convenience)
PLEASE NOTE THIS IS NOT A RADIO RF JAMMER. (it does not transmit RF radio frequencies)
Make sure your private conversations are not recorded, turn on this device and select different operating modes from oscillating white noise, to stealth ultrasonic mode, very low white noise can be heard when operating in this mode.
During operation the device will allow voice conversation in a room or a car to be masked, so, smart phones and digital recording devices will not be able to record your conversations as the ultrasonic white noise and typical white noise will disable the microphones from functioning, giving you a very effective audio jamming system that does not break any radio licensing law in the UK or EU. (This device does not transmit any RF or radio signals)

The device is designed to protect conversations & areas of conversation from eavesdropping devices including: wireless microphones, tape recorders, hard-wired microphones & most of professional digital tape recorders including the ones installed in mobile phones (smartphones), Ultrasonic inaudible noise signal as well as acoustic speech-like noise signal are used to muffle the eavesdropping devices.
The device should be placed so that the transducers are directed towards the possible locations of the eavesdropping devices if possible? These types of device could be tape recorders, microphone, "spy bugs" for example, point the device towards suspicious visitors or clients, basically make sure the device is facing outwards from your speech. The optimal distance from the transducers to microphone of the eavesdropping device is up to 2 meters.
Then switch ON the device and adjust the volume of the acoustic speech-like signal so that you can still hear the person you are talking to. You should hold your conversation at a slightly low voice than usual but so that you hear each other without having to repeat everything. if you feel there is a situation that needs a full response you should use TURBO mode for more effective jamming of any hidden microphone or smart phone microphones.
The device can be connected to external speakers (e.g. computer) through the special jack in order to effectively expose the acoustic speech-like signal in a large room. This will protect a large conversation area from eavesdropping as well as prevent eavesdropping by external directed microphones (such as laser).
