In addition to the functions supported by Version 1.1, Version

functions. Note that the DPC-7.5 doesn’t support all Video
CD PBC functions.
MP3/WMA/JPEG Compatibility
• The DPC-7.5 can play/display MP3, WMA, and JPEG files
recorded on CD-R and CD-RW discs.
• Discs must be in ISO9660 Level 2 format (folders can be up
to eight levels deep).
• Discs must be finalized.
• The DPC-7.5 can only recognize the first session on multises-
sion discs.
• You can determine the order in which the DPC-7.5 plays/dis-
plays your MP3/WMA songs and JPEG pictures by prefixing
file and folder names with a three-digit number. For example
001.Root, 002.Folder, and so on, and 001.Track.mp3,
002.Track.mp3, and so on.
• Only the first eight characters of folder and track names
(excluding the filename extension) are displayed.
• The folder numbered “001” appears as “ROOT” in the Disc
Navigator.
• The DPC-7.5 supports up to 999 folders and up to 672 files per
folder.
• If you try to play an incompatible file, the message “This for-
mat cannot be played” appears on the display.
■
MP3
• MP3 files must be MPEG1 Audio Layer 3 format, 44.1 or
48 kHz, fixed bit-rate.
• MP3 files must have a “.mp3” or “.MP3” filename extension.
• Variable bit-rates (VBR) from 64 kbps to 384 kbps are sup-
ported. (Playing times may display incorrectly with VBR.)
■
WMA
• WMA files must have the copyright option turned off.
• Sampling rates 44.1/48 kHz are supported.
• Variable bit-rates (VBR) from 16 kbps to 192 kbps are sup-
ported. (Playing times may display incorrectly with VBR.)
• WMA files must have a “.wma” or “.WMA” or “.ASF” file-
name extension.
■
JPEG
• JPEG files must have a “.jpg” or “.JPG” or “.JPEG” filename
extension.
• Baseline JPEG files are supported. Progressive JPEG files are
not.
• Only JPEG files with the following brightness/color differ-
ence ratios are supported: 4:4:4, 4:2:2, and 4:1:1.
• JPEG files must be less than 5 megabytes in size.
Handling Discs
• Never touch the underside of a disc. Always hold discs by the
edge, as shown.
• Never attach adhesive tape or sticky labels to discs.
Cleaning Discs
• For best results, keep your discs clean. Fingerprints and dust
can affect the sound and picture quality and should be
removed as follows. Using a clean soft cloth, wipe from the
center outwards, as shown. Never wipe in a circular direction.
• To remove stubborn dust or dirt, wipe the disc with a damp
soft cloth, and then dry it with a dry cloth.
• Never use solvent-based cleaning fluids, such as thinner or
benzine, commercially available cleaners, or antistatic sprays
intended for vinyl records, because they may damage the disc.
