5. Troubleshooting

• No Power:

  Ensure the power adapter is securely connected to both the radio and a working power outlet. Check the power outlet with another device.

• No Sound:

  Check the volume level. Ensure the radio is not muted. Verify that the correct input mode (DAB+, FM, Internet Radio, Bluetooth, USB, AUX-IN) is selected.
• Poor DAB+/FM Reception:

  Fully extend and adjust the telescopic antenna. Try repositioning the radio to a location with better signal strength, away from potential interference sources like other electronic devices.

• Internet Radio Not Connecting/Buffering:

  Verify your Wi-Fi connection in the radio's settings. Ensure your Wi-Fi network is active and has internet access. Check the Wi-Fi signal strength. Restart your router and the radio. If the issue persists, try re-entering your Wi-Fi password.

• Bluetooth Pairing Issues:

  Ensure the radio is in Bluetooth pairing mode. Make sure Bluetooth is enabled on your external device and it is within range. Try unpairing and re-pairing the device. Ensure no other devices are currently connected to the radio via Bluetooth.
• USB Device Not Recognized:

  Ensure the USB device is formatted in a compatible file system (e.g., FAT32). Check that the audio files are in a supported format. Try a different USB device to rule out a device-specific issue.

• UPnP/DLNA Playback Issues:

  Ensure your media server is running and properly configured to share media. Verify that the radio and media server are on the same local network. Check for recent software updates on the radio, as some updates have been noted to affect UPnP functionality (refer to manufacturer support if issues arise after an update).
