6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is off during a power outage. | Unit is operating on battery backup. | This is normal behavior to conserve battery power. The display will return when main power is restored. Ensure AAA batteries are installed for settings retention. |

| Bluetooth device cannot connect. | Device not in pairing mode, or out of range. | Ensure the clock radio's Bluetooth indicator is flashing. Move your Bluetooth device closer to the clock radio (within 30 feet). Restart both devices and try pairing again. |
| Poor FM radio reception. | Weak signal or interference. | Extend and adjust the position of the FM antenna. Try moving the unit to a different location to improve reception. |
