3. Mode Selection (RX / TX)
Use the RX/TX switch on the side of the device to select the desired mode:
- RX (Receiver) Mode: For receiving Bluetooth audio from a source device (e.g., smartphone) and playing it through a non-Bluetooth audio system (e.g., wired speakers, car stereo).
- TX (Transmitter) Mode: For transmitting audio from a non-Bluetooth source device (e.g., TV, PC) to a Bluetooth audio device (e.g., Bluetooth headphones, Bluetooth speaker).
4. Operating in TX (Transmitter) Mode
In TX mode, the BW-BL2 transmits audio from a non-Bluetooth device to a Bluetooth receiving device (e.g., headphones, speaker).
- Switch the device to TX mode.
- Connect the BW-BL2 to the audio output port (e.g., 3.5mm headphone jack) of your non-Bluetooth audio source (e.g., TV, PC) using the 3.5mm Aux cable.
- Turn on your Bluetooth headphones or speaker and set them to pairing mode.
- The BW-BL2 will automatically search for and connect to nearby Bluetooth receiving devices. The LED indicator will show a solid light once connected.
- Play audio on your source device, and it will be transmitted to your Bluetooth headphones/speaker.
5. Operating in RX (Receiver) Mode
In RX mode, the BW-BL2 receives Bluetooth audio from a source device (e.g., smartphone) and plays it through a non-Bluetooth audio system (e.g., wired speakers).
- Switch the device to RX mode.
- Connect the BW-BL2 to the audio input port (e.g., 3.5mm AUX-in) of your non-Bluetooth audio system (e.g., wired speaker, car stereo) using the 3.5mm Aux cable.
- Enable Bluetooth on your smartphone or other Bluetooth audio source and search for available devices.
- Select "BW-BL2" from the list of available devices to pair. The LED indicator will show a solid light once connected.
- Play audio on your smartphone, and it will be received by the BW-BL2 and played through your connected audio system.
Maintenance
- Keep the device dry. Moisture can damage electronic circuits.
- Do not expose the device to extreme temperatures.
- Avoid dropping or subjecting the device to strong impacts.
- Clean the device with a soft, dry cloth. Do not use harsh chemicals or detergents.
- Store the device in a cool, dry place when not in use for extended periods.
Troubleshooting
- Device won't turn on: Ensure the device is fully charged. Connect it to a power source using the Micro USB cable.
- Cannot pair with a Bluetooth device:
- Ensure the BW-BL2 is in the correct mode (TX for transmitting, RX for receiving).
- Make sure the target Bluetooth device is in pairing mode.
- Keep the BW-BL2 and the target device within 10 meters (33 feet) of each other.
- Try restarting both the BW-BL2 and the target Bluetooth device.
- Clear previous Bluetooth connections on your source device if necessary.
- No sound or poor audio quality:
- Check all 3.5mm Aux cable connections to ensure they are secure.
- Verify that the volume on both the BW-BL2 and the connected audio device is turned up.
- Ensure the BW-BL2 is correctly paired and connected.
- Move closer to the connected device to rule out range issues.
- Can it connect to two Bluetooth headphones simultaneously? The BW-BL2 supports connection to one Bluetooth device at a time in both TX and RX modes.
User Tips
