PowerCom and PowerCom Plus 2-way radio headsets have a programmable frequency range between 462 to 467 mHZ and a 30-channel capacity. Other features include 38 privacy tones to avoid unwanted frequency chatter, voice-activated transmitting or push-to-talk on the back left ear cup, and a noise-canceling boom microphone. Two headband configurations are available: a neckband for use with or without hardhats and a hardhat clip-in for use with slotted hats.
