About the RESTORER function
Compressed audio formats such as MP3, WMA (Windows Media Audio)
and MPEG-4 AAC reduce the amount of data by eliminating signal
components that are hard for the human ear to hear. The RESTORER
function generates these signals that are eliminated upon compression,
restoring the sound to a similar state as the original uncompressed sound.
n Operations

The noise cancellation function and the
RESTORER function turn on, and the
RESTORER indicator lights white.
