3. Fail to be connected with a Bluetooth device (Bluetooth headset)? Answer: Put the Bluetooth adapter closer and start the device again and connect the Bluetooth headset and other devices again. If that fails to work, you can restart the adapter and the Bluetooth headset to ensure that they have entered the waiting state for pairing.

4. No sound output?
   Answer: Please check whether the 3.5mm audio line is connected correctly; the audio line shall be inserted to the audio output interface under the transmitting mode and the audio line shall be inserted to the audio input interface under the receiving mode. At the same time, please check whether all current signal sources are correct. If wrong interfaces are found, please double press C) to switch to the correct signal sources.

5. No sound after the digital optical/coaxial cable is inserted? Answer: Determine the current working mode; if it is RX receiving mode, digital fiber/coaxial input will be switched to AUX/RCA analog signals, which will be output to the ordinary speaker through the wire. If TX transmitting mode is used, the digital optical/coaxial input will be switched to analog signals, which will be output to Bluetooth headset Bluetooth speaker

6. What devices can be used?
   Answer: All devices with audio input or output interfaces, such as computer, television, active soundbox, home loudspeaker, office acoustics, vehicle, power amplifier, projector, wired earphone.
