Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Doorbell does not ring or light up. | Low or dead battery in transmitter. | Replace the CR2032 battery in the transmitter. |
| Receiver not plugged in or no power. | Ensure the receiver is securely plugged into a working U.S. electrical outlet. | |
| Transmitter and receiver are not paired. | Refer to the full user manual for re-pairing instructions if needed. The power-off memory function should prevent this in most cases. | |
| Short operating range. | Obstacles (thick walls, metal structures) or interference. | Relocate the receiver or transmitter to minimize obstructions. Avoid placing near large metal objects or other wireless devices. |
| Unwanted ringing or no response. | Interference from other devices. | Try changing the melody to see if it resolves the issue. |
