- 12 years ago
Remote beeper has two parts: receiver and transmitter. Both two are small enough for you to carry in the pocket. If you want to call other people, press the button on transmitter and the receiver will beep to alert. The receiver can be controlled by transmitter from any place within a reliable distance; the wireless signal can pass through walls, floors and doors.
