4. Select 'Digital Output'.
5. Change the setting to 'Digital Stereo'.

5. Operating Instructions

5.1 Power On and Re-connection

Once connected to a power source, the SW03 will automatically power on. It will then enter re-connection mode, attempting to connect to the last paired Bluetooth devices. During this phase, the blue LED indicators 'A' and 'B' will flash slowly. If successful, the blue LEDs will remain steadily on. If no connection is established within 15 seconds, the device will automatically enter searching mode.

5.2 Pairing New Bluetooth Devices

1. If the device is not already in searching mode, you can double-click the 'O' (Searching) button to enter searching mode directly. The blue LED 'A' will flash quickly.
2. Turn on your Bluetooth headset or speaker and ensure it is in pairing mode (refer to your Bluetooth device's manual).
3. The SW03 will automatically pair with your Bluetooth device. Once the first device is successfully connected, blue LED 'A' will be steadily on.
4. The transmitter will then automatically search for a second device. Blue LED 'B' will flash quickly.
5. Turn on your second Bluetooth headset or speaker and put it into pairing mode. Once successfully connected, blue LED 'B' will be steadily on. Both blue LEDs 'A' and 'B' will be continuously lit, indicating two connected devices.
6. If no connection is made within 50 seconds during the search, the search will stop. You can click the 'O' button to restart the search.

5.3 Switching Audio Transmission Mode

To switch between USB Audio Mode and Optical Audio Mode:

• Click the 'USB/Optical Switch' button.
• When the red 'Optical' LED is lit, the transmitter is in Optical Audio Mode.
• When the red 'Optical' LED is off, the transmitter is in USB Audio Mode.

Ensure you select the correct audio transmission mode corresponding to your device's connection.

5.4 Clearing Pairing Records

To clear all previously paired Bluetooth devices from the transmitter's memory:

7. Troubleshooting

• No sound or low audio output: Ensure the SW03 is correctly connected and powered. Verify that your audio source (TV, PC, console) is outputting audio through the selected interface (USB or Optical) and that its volume is turned up. For Xbox 360, confirm 'Digital Stereo' is selected in audio settings. Also, check the volume on your Bluetooth receiving device.
• Unable to pair: Make sure your Bluetooth receiving device is in pairing mode and not connected to other devices. Turn off Bluetooth on other nearby devices that might interfere. Clear the pairing records on the SW03 and try again.
• Interference/Poor signal: The SW03 uses 2.4GHz wireless transmission. Avoid placing it near high-power electrical appliances (e.g., induction cookers, microwave ovens) or in areas with many obstacles that could block the signal.
• SW03 not appearing in device list: The SW03 uses the latest Bluetooth chip technology and is designed for automatic connection. It will not appear in the Bluetooth device list of your phone, computer, or TV. Simply bring your Bluetooth device close to the transmitter for automatic connection.

8. User Tips

• For optimal performance, ensure your Bluetooth headphones or speakers are fully charged before use.
• When connecting two Bluetooth devices, using devices of the same model or with the same audio format encoding can provide the best experience.
• Many users report excellent connectivity and low latency, making it suitable for gaming and watching movies.
