Devices that are to be prevented from recording commu- nication can be placed on the board freely (they may over- lap, this does not significantly reduce efficiency)
• When the cover is closed (having the small switch magnet facing to the back side), device automatically starts generating ultrasound which overwhelms the micro- phones of the devices inside and completely prevents any sound recording in the room.
• Acoustic signal corruption caused by ultrasound and by limitation of electric signals in device circuits makes origi- nal audio signal unrecoverable.
• The device has a built-in timer which is factory set for 3 hours (other times can be set on request). After this time, the ultrasound interference will be switched off even if the cover is covered. To continue jamming, simply lift cover slightly and put it down again.
• There are two versions of the device. Mains only pow- ered, and accumulator powered, with approx. 5 hours of operation from accumulator.
• To keep the box covered, but inactive, rotate the cover by 180°, i.e. place the small switch magnet on the cover side forward.
• Device is 100% safe. There is no risk of damage micro- phones or any other circuits of the devices placed inside
