.Discs with copy protection.
New Disc
Some new discs may have burrs
found in the center hole or at the
edges. Remove these burrs with a
ballpoint pen, etc. before using
the disc.
If they are not removed, the disc
may not be read accurately and
cause improper operation.
Rental Discs
Do not use any disc that has
cellophane tape or any rental disc
that has glue from the label exposed
or some of the removed label still
attached to it. Using the disc like
this may cause the disc to not eject
properly and damage the disc.
Discs with Special Shapes
Heart-shaped or octagon-shaped
discs cannot be played. Do not use
them as they may cause damage.
Disc Accessories
Do not use commercially available
accessories (such as stabilizers,
protective seals, etc.) that are said to improve sound quality or protect
the discs, and CD labels, etc. They
may change the thickness of the
disc and external specifications and
lead to damage.
Do not use commercially available
accessories (such as CD rings,
protectors) that are said to improve
sound quality or are effective
against vibrations. They may come
off inside the device, causing the
disc to become unplayable or
unretrievable and lead to
malfunction.
MP3/WMA Files
MP3 (MPEG Audio LAYER 3) is a
standard format for sound
compression technology.
By using MP3, a file can be
compressed to one-tenth the size of
the original.
WMA (Windows Media Audio) is a
Microsoft sound compression
format. It can compress sounds to a
smaller size than the MP3.
This deck has limitations on MP3/
WMA file standards and recorded
media and formats that can
be used.
