ABSTRACT:
The hands-free, two-way communication radio includes a multiple channel transmitter/receiver having one of the channels designated a primary communication channel. The transmitter/receiver is also operable in a scan mode to scan multiple channels for communication signals. The radio also includes an interface operatively connected to the multiple channel transmitter/receiver and a hands-free microphone operatively connected to the transmitter/receiver through the interface. A foot pedal actuator is provided for keying the hands-free microphone to allow transmission of a message over the multiple channel transmitter/receiver. Further, the radio includes a switching mechanism operative in response to actuation of the foot pedal for providing a control signal to the multiple channel transmitter/receiver. This control signal results in the multiple channel transmitter/receiver switching to the primary communication channel for transmission of the message. The invention also includes the combination of the interface, hands-free microphone and foot pedal actuator and switching system for retrofit conversion of a standard radio to hands-free operation.
