Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Doorbell does not ring | Transmitter battery is dead or low. Receiver is unplugged or uncharged. Distance too far or too many obstacles. | Replace transmitter battery. Ensure receiver is plugged in and charged. Reduce distance between transmitter and receiver, or relocate to minimize obstructions. |
| Chime volume is too low or too high | Volume setting is incorrect. | Press the Volume button on the receiver to adjust to the desired level. |
| Chime is not the desired melody | Incorrect chime selected. | Press the Tone button on the receiver to cycle through and select a new chime. |
