Using AC-3® to Optical Digital Audio Output
MiniDisc player/recorders, DAT player/recorders, and older digital
receivers do not support Dolby® Digital (AC-3). You should not use the
AC-3 to Optical Digital Audio Output option unless you are using a
device that supports Dolby Digital. Please refer to the manual supplied
with your equipment to determine if it supports Dolby Digital. If you are
unsure and you have selected the AC-3 to Optical Digital Audio Output
option, turn down the volume on your equipment before using the DVD
player.
Using America Online or Sony Online Support with WinFax®
Basic Edition
Once you have configured WinFax Basic Edition, it is automatically
available for your use. You cannot use America Online or Sony Online
Support when the automatic fax receive feature of WinFax Basic Edition
is on. To disable this feature, right click the WinFax icon in the task tray at
the bottom right corner of your screen, and then select Exit.
