Troubleshooting
| Problem | Possible Cause / Solution |
|---|---|
| No power / Display off | Ensure power adapter is securely plugged into the unit and a working wall outlet. Check the power outlet. |
| Alarm does not sound | Ensure the alarm is activated (alarm icon visible). Check alarm volume. Verify alarm time is set correctly. |
| Poor FM radio reception | Adjust the position of the unit. Extend the FM antenna (if applicable, internal for this model). Try auto-scanning for stronger signals. |
| Bluetooth device cannot pair | Ensure the alarm clock is in Bluetooth pairing mode (flashing BT icon). Make sure Bluetooth is enabled on your device and it's within range. Forget previous pairings on your device and try again. |
| App control not working | Ensure the app is updated. Verify Bluetooth connection between the app and the clock. Restart the app or your phone. |
| Time drifts / Incorrect time | Reset the time manually. If frequent, the backup battery may be weak (though it primarily holds settings during power loss, not for continuous accuracy). |
