Users are requested to use the "Safely remove hardware" function during the disconnection process and wait until the message "Safe to remove hardware" appears before disconnecting the vocal element from the PC. Alternatively, music files can be transferred to the vocal element using a different operating system (e.g. Windows 2000/XP or Linux).
