VIC-3 U-94 Series Headset Controller allows an operator to conveniently connect to a VIC-3 extension cable (AP-107 connector) and take advantage of our three-function controller. Our controller is based upon the design of the U-94 PTT with a large, robust toggle switch. The U-94 VIC-3 controller PTT allows an operator to specify "Hot Mic" mode for full-duplex communications through VIC-3, or "Mic Mute" mode. An operator can also transmit on a VIC-3 integrated radio by keying the toggle switch.
