5. Operating Modes
5.1 Transmitter Mode (TX)
In TX mode, the adapter transmits audio from a non-Bluetooth source (e.g., TV, PC) to Bluetooth-enabled receiving devices (e.g., Bluetooth headphones, Bluetooth speakers).
- Connect the adapter's input (AUX, RCA, Optical, or Coaxial) to your audio source (e.g., TV audio output).
- Set the adapter to TX mode. The LED display will show 'TX'.
- Place your Bluetooth receiving device (headphones/speakers) in pairing mode.
- The adapter will automatically search for and connect to nearby Bluetooth devices. Once connected, audio from your source will be streamed wirelessly.

5.2 Receiver Mode (RX)
In RX mode, the adapter receives Bluetooth audio from a source device (e.g., smartphone, tablet) and outputs it to a non-Bluetooth audio system (e.g., wired speakers, home theater system).

5.3 FM Transmitter Mode (FM)
In FM mode, the adapter transmits audio from a source device (e.g., smartphone, tablet) as an FM radio signal, which can be picked up by an FM radio (e.g., car radio, portable radio).
- Connect your smartphone/tablet to the adapter via Bluetooth (as in RX mode).
- Set the adapter to FM mode. The LED display will show 'FM' and a frequency.
- Tune your FM radio to the same frequency displayed on the adapter.

8. Troubleshooting
If you encounter issues with your Beedove Bluetooth Adapter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound or low volume | Incorrect mode selected; volume too low; incorrect cable connection; incompatible audio format. | Ensure the correct mode (TX/RX/FM) is selected. Increase volume on both the adapter and connected devices. Verify all audio cables are securely connected to the correct input/output ports. Check if the audio format is supported. |
| Cannot pair with Bluetooth device | Adapter not in pairing mode; device too far; interference; previously paired device connected. | Ensure the adapter is in the correct mode (TX for transmitting, RX for receiving) and in pairing state. Keep devices within 10 meters. Turn off other Bluetooth devices to reduce interference. Disconnect from any previously paired devices. Try NFC pairing for RX mode if supported. |
| Remote control not working | Battery depleted; line of sight blocked; remote not pointed at adapter. | Replace the remote control battery. Ensure there is a clear line of sight between the remote and the adapter's infrared receiver. Point the remote directly at the adapter. |
| FM transmission static or poor quality | Interference from other FM stations; weak signal. | Try a different FM frequency on the adapter and tune your radio to match. Ensure the adapter is placed in an optimal position for signal transmission. |
| Device not charging or holding charge | Faulty charging cable/adapter; battery issue. | Try a different USB charging cable and power adapter. If the issue persists, contact customer support. |
