Designed as a discreet detection unit, the DD-28 AM/FM clock radio quickly and silently alerts you to the presence of privacy invasion from clandestine RF transmitting devices in your home or office. Housed in a fully functional, attractive radio, the DD-28 is unobtrusive and fits well into an office or home environment.

The DD-28 utilizes AC power from the radio and blanks out the red LED digits on the clock whenever room RF goes above a preset threshold. You can set the threshold at any time by means of a small adjustment knob on the back of the radio. A fine wire antenna exits the rear of the unit and can be draped out of sight over the edge of a desk or table.
