From the introduction in the H200/U manual: "Sound-powered telephones are just what the name implies. They are telephones powered by the sound pressure of your voice rather than batteries or an electrical power source. If your phones work properly, speaking in a strong, clear voice generates enough current to carry your voice to all other phones on the circuit.".
