wireless doorbell WA-XX01-N9

Installation Method: Use double-sided adhesive tape to stick the transmitter on the wall. Press for 30 seconds for a firmer adhesion. Place the transmitter outside the door, and the doorbell host will ring immediately when pressed. Plug the host into a 220V socket (install it indoors) for power.

Special Function: The doorbell has a power-off memory function, eliminating the need to reset the ringtone repeatedly. With a honeycomb sound cavity design on the front, sound can travel unobstructed through walls. It has a working range of up to 300 meters, making it suitable for use on the 1st - 3rd floors.

Precautions: Do not install the doorbell on metal doors, as metal can block signal transmission and affect its performance.
