Safe Line offers more levels of protection than any other device of it's kind! Six levels of protection deactivate, neutralize, monitor and alert you to eavesdropping attempts. Both "on hook" and "off hook" line voltages are constantly displayed, alerting you to any type of equipment or "bug" that has been added to your phone line. Common "voltage sensing" telephone recorder wiretaps (readily available at electronics stores) will never even know you are on the line, remaining in standby mode and never recording anything.

The same thing goes for parasitic line transmitters. High tech crystal controlled parallel line transmitters will be automatically "shifted" off their frequency to transmit nothing but static "noise". Even the feared VOX (voice-activated) systems are neutralized by the Safe Line Anti-Vox System. VOX recording systems are forced to run continuously when your phone in not in use, filling up their recording media with "noise". You are instantly alerted to any extension eavesdroppers by a special "muting" circuit that stops your conversation until the offender "hangs up" or you override the system by switching off the unsafe/safe switch.

SPECIFICATIONS:Digital display will reflect any change in your phone line. Automatically deactivates all known wiretapping devices. Creates shift of frequencies in crystal line transmitters.Voice "simulation" causes VOX equipment to record noise when line is not in use-filling up any type of recording media.Turns off voltage sensing recording/transmitting devices. Instantly alerts user to extension eavesdropping attempts. 100% state-of-the-art digital surface mount technology.
