The doorbell transmitter and the doorbell receiver are paired at the factory and can be used directly. 2. Please do not install the doorbell transmitter on an iron or steel door. Iron or steel has a strong shielding effect on wireless signals, which will cause the wireless signal between the transmitter and the doorbell receiver to be unable to transmit, resulting in malfunction. 3. It is recommended that the doorbell receiver be at least 50cm above the ground to increase the reception strength of the wireless signal. Warm tips: 1. This product enjoys a one-year warranty and lifetime paid maintenance. The maintenance costs are paid by the customers. 2.
