Protects against phone/fax/modem interception.
R.F. Detection: detects R.F. transmitters on the phone line.
Voltage Display: By comparing voltage read-out to the supplied chart you can tell at a glance if your phone is safe.
Voltage Adjustment: Stretches your phones voltage to the maximum limit, leaving just enough power to operate your phone, rendering eavesdropping equipment useless (I.E. bugs, phone recorders, and extension eavesdropping).
Silent Monitoring: Gives you the option to monitor a phone conversation on your line at any time (check local and state laws). Also verifies audio while phone is on hook in order to detect infinity transmitters. Automatic conversation cut off in order to assure your maximum protection without constant viewing of your voltage display.
