3. Transmitter Mode (TX)
In TX mode, the device transmits audio from a non-Bluetooth source (e.g., TV, airplane entertainment system, computer) to Bluetooth-enabled headphones or speakers.
- Set the TX/RX OFF switch to "TX".
- Connect the device's 3.5mm audio jack to the audio output port of your source device (e.g., headphone jack on a TV, airplane seat, or computer). Use the appropriate adapter if necessary (e.g., airplane audio plug).
- Put your Bluetooth headphones or speakers into pairing mode.
- The eppfun device will automatically search for and connect to nearby Bluetooth devices. The LED indicators will show pairing status and the active audio codec.
- For dual connection, after the first device is paired, put the second Bluetooth headphone/speaker into pairing mode. The eppfun device will attempt to connect to the second device.
