The "new" Tap Buster PLUS will defeat telephone tapping and telephone taping attempts. Line activated tape recording controls, line transmitters or any other voltage-activated devices, will not function. The Tap Bluster PLUS will also send a constant tone through the line (on-hook) defeating the operation of a VOX Tele Recorder. This new unit will also, still alert you to an extension phone eavesdropper. No batteries are required.
Easy to install, no adjustment necessary. Simply plug the cord from the Tap Buster PLUS into your telephone wall jack, then plug your telephone cord into the Tap Buster PLUS. If the green indicator lights is lit, your line is safe. If the green light goes out while you're on the line, and your line goes dead, this is a clear indication of an eavesdropping attempt. Another phone on your line may be off hook or someone on premise is listening on an extension. When using the Tap Buster PLUS, the green light should be lit if your phone line is safe.
