About the product

Wireless calls require batteries and wires! This button uses unique energy harvesting technology. When you press the button, the internal energy conversion module converts energy into electrical energy. Then the wireless button module sends a signal to the receiver. The receiver receives the signal and turns on/off the call power, then hears a ringing tone.
