at high volume while walking, especially at
pedestrian crossings. You should exercise
extreme caution or discontinue use in
potentially hazardous situations.
Preventing hearing damage
Avoid using headphones/earphones at high
volume. Hearing experts advise against
continuous, loud and extended play. If you
experience a ringing in your ears, reduce
volume or discontinue use.
Consideration for others
Keep the volume at a moderate level. This
will allow you to hear outside sounds and to
be considerate to the people around you.
Additional information
On the water resistance
• Before unfastening the buckle to open the
lid, be sure to wipe off water, dust or sand
on the exterior of the unit. Open and close
the lid where water or sand cannot fall in
the unit, and make sure that your hands are
dry. If water or sand falls in the unit,
trouble may occur.
• When closing the lid, check that there is no
dust or sand on the rubber packing around
the lid. Then close the lid firmly with the
buckle.

Precautions
• The supplied headphones are not meant to
be immersed in water or come in
continuous contact with water. If they are
accidentally dropped into water or get wet,
dry them with a soft cloth. Never use an
electric hair dryer.
• The supplied AC power adaptor is not
water resistant. To prevent shock hazard,
avoid using the player near water during
AC operation.
• Cover the DC IN 4.5 V jack and i jack
with the attached rubber caps when
nothing is connected to these jacks. If the
inside of the jacks are contaminated with
water or sand, rust may develop and cause
trouble.
Notes
• Since the unit is airtight, you may not be able to
open the lid when there is a sudden change in air
pressure inside the unit. This happens when the
unit is transported on a plane or moved from a
warm place to a cold place. In this case, open the
rubber cap on the DC IN 4.5 V jack.
• To prevent water from leaking in, the buckle is
designed to be slightly stiff. Be careful not to
catch a fingernail on the buckle when unfastening
the lid.
Maintenance
To clean the casing
Use a soft cloth slightly moistened in water
or a mild detergent solution. Do not use
alcohol, benzine or thinner.
To clean the headphones/
earphones plug
Keep the plug of your headphones/earphones
clean to obtain optimum sound. Wipe it with
a dry, soft cloth.
To remove any dust or sand
from the rubber packing
Any sand or dust on the rubber packing will
prevent the lid from shutting tightly, and
water may leak in. Brush off the dust once in
a while.
We recommend the replacement of the
rubber packing every year which is available
optionally at an authorized Sony service
facility.
Do not hold the player with the buckle
by itself. Doing so may damage the
unit.

About “MP3”
What is the MP3?
MP3 (MPEG 1 Audio Layer-3) is a standard
technology and format for compressing a
sound sequence. The file is compressed to
about 1/10 of its original size. Sounds
outside the range of human hearing are
compressed while the sounds we can hear are
not compressed.
Playable “MP3” files on this
player
You can only play MP3 files recorded by
following requirements.
USABLE MEDIA
CD-Rs and CD-RWs
USABLE DISC FORMAT
You can use ISO 9660 Level 1/2 and Joliet
extension format discs. This unit can display
only 1-byte characters. (2-byte characters
like those of Japanese are displayed as “–.”)
The major specification of the usable disc
format is:
• Maximum directory steps: 8
• Usable characters for a file/folder name:
A - Z, 0 - 9, _ (underscore)
• Maximum number of characters for a file
name: 64 and a 3-character extension code
THE USABLE NUMBER OF FOLDERS/
FILES
• Maximum number of folders: 255
• Maximum number of files: 255
SETTINGS FOR COMPRESSION
SOFTWARE AND WRITING
SOFTWARE
• To compress a source for an MP3 file, we
recommend setting the transfer bit rate of
the compression software to “44.1 kHz”,
“128kbps,” and “Constant Bit Rate.”
• To record up to the maximum capacity, set
to the “halting of writing”.
• To record at one time up to the maximum
capacity on media that has nothing
recorded on it, set to “Disc at Once.”
NOTES FOR SAVING FILES ON THE
MEDIA
When the disc is inserted, the player reads all
the files on that disc. If there are many
folders or non-MP3 files on the disc, it may
take a long time for play to begin or for the
next MP3 file to start play.
Do not save unnecessary folders or files other
than MP3 ones in the disc to be used for
MP3 listening.
We recommend that you do not save other
types files or unnecessary folders on a disc
that has MP3 files.
Additional information
Notes
• When naming, be sure to add the file extension
“mp3” to the file name.
• If you put the extension “mp3” to a file other than
an MP3 file, the player cannot recognize the file
properly.
• The file name does not correspond to the ID tag.
About “ID3 tag”
ID3 tag is a format for adding certain
information (track name, album name, artist
name, etc.) to MP3 files.
Note
This CD player conforms to Version 1.1 of the ID3
tag format. If you use a version other than 1.1, ID3
tag information will not be displayed correctly, but
the file can be played back.
