False alarms are easily terminated by re-pressing the button. When the transmitter is activated, the system calls the first of up to eight programmed numbers. When someone answers, a pre-recorded message tells them that you need help. The Voice Response unit automatically sets up a hands free, two way communication through its powerful microphone. If no one answers, the unit cycles through all programmed phone numbers four times until somone responds.
Advanced technology allows the system to ignore answering machine pick-ups.
