About MP3/WMA files
MP3, which stands for MPEG-1 Audio Layer-3, is a
music file compression format standard. It
compresses audio CD data to approximately 1/10 of
its original size.
WMA, which stands for Windows Media Audio, is
another music file compression format standard. It
compresses audio CD data to approximately 1/22*
of its original size.
* only for 64 kbps

Playback order of MP3/WMA files
Notes
• When naming an MP3 file/WMA file, be sure to add
the file extension “.mp3”/“.wma” to the file name.
• During playback of a VBR (variable bit rate) MP3/
WMA file or fast-forward/reverse, elapsed playing
time may not display accurately.
• When the disc is recorded in Multi Session, only the
first track of the first session format is recognized
and played (any other format is skipped). The
priority of the format is CD-DA and MP3/WMA.
– When the first track is a CD-DA, only CD-DA of the
first session is played.
– When the first track is not a CD-DA, an MP3/WMA
session is played. If the disc has no data in any of
these formats, “NO MUSIC” is displayed.
Notes on MP3
• Be sure to finalize the disc before using on the unit.
• If you play a high-bit-rate MP3, such as 320 kbps,
sound may be intermittent.
Notes on WMA
• Files made with lossless compression are not
playable.
• Files protected by copyright are not playable.
If you have any questions or problems concerning
your unit that are not covered in this manual, consult
your nearest Sony dealer.
Maintenance
Replacing the lithium battery of the
card remote commander
Under normal conditions, the battery will last
approximately 1 year. (The service life may be
shorter, depending on the conditions of use.)
When the battery becomes weak, the range of the
card remote commander becomes shorter.
Replace the battery with a new CR2025 lithium
battery. Use of any other battery may present a
risk of fire or explosion.
Notes on the lithium battery
• Keep the lithium battery out of the reach of children.
Should the battery be swallowed, immediately
consult a doctor.
• Wipe the battery with a dry cloth to assure a good
contact.
• Be sure to observe the correct polarity when
installing the battery.
• Do not hold the battery with metallic tweezers,
otherwise a short-circuit may occur.
Fuse replacement
When replacing the fuse, be
sure to use one matching the
amperage rating stated on the
original fuse. If the fuse blows,
check the power connection and
replace the fuse. If the fuse
blows again after replacement,
there may be an internal
malfunction. In such a case,
consult your nearest Sony
dealer.
