Shuffle on DVD Audio Press the pushbutton located under the Shuffle label to begin random playback of all songs in the current Group. Press again to turn off random playback. Care of Your CD and DVD-A Discs If playing a CD or DVD-A disc, the sound quality can be reduced due to disc quality, the method of recording, the quality of the music that has been recorded, and the way the disc has been handled. Handle them carefully. Store disc(s) in their original cases or other protective cases and away from direct sunlight and dust. The CD/DVD-A player scans the bottom surface of the disc. If the surface of a disc is damaged, such as cracked, broken, or scratched, the disc may not play properly or not at all. Do not touch the bottom side of a disc while handling it; this could damage the surface. Pick up discs by grasping the outer edges or the edge of the hole and the outer edge. If the surface of a disc is soiled, take a soft, lint free cloth or dampen a clean, soft cloth in a mild, neutral detergent solution mixed with water, and clean it. Make sure the wiping process starts from the center to the edge. Selecting DVD Audio Streams Each DVD audio Group may contain audio content that is encoded in one or two formats. For example, a particular Group may have both a 5.1 surround audio stream and a 2.0 stereo audio stream available. Press the pushbutton located under the Audio label to display the current audio stream playing. "Audio Stream 1" or "Audio Stream 2" briefly displays. Press the pushbutton located under the Audio label again to toggle between Audio Stream 1 or Audio Stream 2 (if available). Check the DSP settings to determine if a 5.1 surround sound Audio Stream is playing. See "Digital Signal Processing (DSP)" earlier in this section. Press the DSP label to see if the 5.1 + Normal or 5.1 + Rear settings are available for selection. If these settings are available, Audio Stream 1 is playing. 3-90
