The PC-USB operating instructions are as follows:

1. Connect the PC-USB interface on the rear panel of the machine to the factory-configured USB cable (USB supports hot plugging).
2. Press the input signal selection button to select the USB input.
3. Locate the sound icon in the lower right corner of the PC.
4. Right-click the PC sound icon in the lower right corner and select "Select Play Player".
5. A pop-up dialog box will appear to select the playback device recognized by the PC (this machine's USB is automatically recognized, no need to manually install the driver).
6. Click to confirm the recognized digital output (open the Volume Mixer, click on the device/SPDIF icon "Digital HiFi Audio" to open the Properties, click Advanced, and select 24Bit, 96000Hz for maximum sound quality output).

Note: If there is no audio output when connecting the TV, you need to adjust the TV's audio source output to optical fiber or coaxial output. Remember to switch to the corresponding input mode. PC-USB/Optical/Coaxial input are selectable.

With USB, Optical, or Coaxial Digital Audio input, there are 3.5mm headphone and RCA audio outputs. When both RCA and headphone outputs are connected, the RCA output will not work, and the headphone playback will take priority. To use the RCA output, the headset needs to be disconnected.
