Setup and Pairing
The adapter supports both Transmitter (TX) and Receiver (RX) modes. Use the toggle switch on the side of the device to select the desired mode.
TX Mode (Bluetooth Transmitter)
In TX mode, the adapter transmits audio from a non-Bluetooth device to Bluetooth headphones or speakers.

- Long press the multifunction key to power on the adapter.
- Push the mode toggle switch to TX. The red indicator light will flash quickly, indicating it is in pairing mode.
- Turn on your Bluetooth headphones or speakers and set them to pairing mode.

Note: The first connection may take a few seconds. After successful connection, the adapter will automatically reconnect to the paired device next time it's powered on. If pairing fails, double-click the multifunction button to search again, or power off and restart both the adapter and the Bluetooth audio device.
Important for TVs: Ensure you connect the adapter to an audio output port (RCA or 3.5mm) on your TV, not an audio input port.
