liquid cleaners or solvents should be used.
Cleaning
Q: All the cables are connected, but no sound output?
A: 1. Check the indicator is on, turn on the power if the light is still off, at this point
you can find a same output voltage power supply (must 12V) to check if the
machine or power supply failure.
2. If the indicator light is on, check whether the select knob is in the right position.
3. If both of the above are normal, check the input device if it is paused.
Troubleshooting

Q: Why do loudspeakers make a lot of electric noise?
A: If you are not using the original factory standard power supply, please replace
the power supply before testing. Many power supply in the market have large
interference coefficient, which will cause a lot of current sound.
Q: Why the speaker has drone when I just plug in the input cable but
don’t connect the sound sources?
A: If you use unshielded signal lines, there will be interference signals entering the
power amplifier. If you hate the sound, you are advised to use the shielded signal
lines or unplug the signal lines.
Q: Why there is no sound when PC-USB connects to PC?
A: First press the PC-USB operation to confirm whether the digital playback output
has been selected. If still no sound, you can restart the computer and repeat the
operation again.
Q: USB Device not recognized on Windows?
A: 1. Select Start, then type device manager in the Search box, and then select
Device Manager;
2. Expand Universal Serial Bus controllers. Press and hold (or right-click) a device
and select Uninstall. Repeat for each device;
