MP3/WMA Compatibility
Storage precautions
< Discs should be returned to their cases after use to
avoid dust and scratches that could cause the laser
pickup to “skip.”
< Do not expose discs to direct sunlight or high-
temperature and humidity for extended periods. Long
exposure to high temperatures will warp discs.
< CD-R and CD-RW discs are more sensitive to the effects
of heat and ultraviolet rays than ordinary CDs. It is
important that they are not stored in locations where
they will be exposed to direct sunlight. They should also
be kept away from sources of heat, such as radiators and
heat-generating electrical devices.
Maintenance
< If a disc becomes dirty, wipe its surface radially from the
center hole outward towards the outer edge with a soft,
dry cloth.
< Never clean discs using chemicals such as record sprays,
antistatic sprays and fluids, benzene and thinner. Such
chemicals will do irreparable damage to the disc’s
plastic surface.
This unit can play MP3/WMA files recorded on a CD-R,
CD-RW discs and USB storage device. Refer the instruction
manual of the software when making an MP3 or a WMA
file using a PC.
< This unit can play back monaural and stereo MP3
files that are in the MPEG-1 Audio Layer 3 format with
a sampling rate of 44.1 or 48 kHz and a bit rate of
320 kbps or less.
< WMA file must have a sampling rate of 44.1 kHz, and a
bit-rate of 192 kbps or less.
< This unit is not compatible with discs that have been
recorded using multiple sessions. Only the first session
can be played back.
< This unit cannot play copyright protected files.
File information display
The display of this unit can only show single-byte letters
and numbers.
< If the file information contains Japanese, Chinese or
other double-byte characters, playback is possible but
the name will not be shown correctly.
Cautions when preparing MP3/WMA files using a
computer or other device
< Always include the extension in the file name. This unit
recognizes MP3 files by their “.mp3”, and WMA files by
their “.wma” file extensions.
< Always close the session (complete disc creation).
This unit cannot play discs if the session has not been
closed.
< Carefully read the manual for the software that you are
using when you create an MP3/WMA disc.
Files that are unplayable or only partially playable
< Files without extensions cannot be played. Files that are
not in the MP3/WMA format cannot be played even if
they have extensions.
< Variable bit rate files might not play back correctly.
< If the disc/USB storage device contains more than
99 files or 99 folders, this unit can not play it back
correctly.
< Depending on disc/USB storage device conditions, this
unit might not be able to play a disc or skipping might
occur.
