If the pairing between the transmitter and receiver is accidentally cleared (e.g., by long-pressing the volume button), the chime may stop ringing. To re-pair the devices: a. Press and hold the "Next Chime" button on the receiver for over 3 seconds. You will hear a "ding dong" sound, indicating the receiver is in pairing mode b. Separate the magnetic sensor parts (move the door sensor magnet away). The chime receiver will play the default chime sound, confirming that the pairing is successfully completed
