The wireless doorbell is suitable for homes, offices and shops. When pressed, the button generates the energy needed to transmit the signal, so it does not require a battery. The receiving units are plugged into a 200–240 V mains supply.
Main advantages:
Before first use, connect both receivers to the mains and then press the external button. If one of the receivers does not ring, pair the devices by simultaneously holding the melody button on both receivers for 3 seconds. Successful pairing is confirmed when both units ring simultaneously.
