7. Important Notes
1. When USB audio device has been wearing out caused by plugging and
unplugging too often or disconnecting device too fast from the computer,
the system may not be able to detect the change in time. In this case,
switch the USB audio device manually.
2. Please pay attention: Do not unplug the device while player
software or Microphone is operating; Do not unplug the device while
the red light of controller box is flashing. This indicates operation of any
player software or Microphone is on; Doing so could damage the normal
operation of the system. The correct way is to close all player programs
and microphone functions. Wait until red light of controller box stops
flashing and stays led before unplugging the USB device.

etc. are required to provide Dolby Digital AC-3 and DTS 5.1 channel
