shock than expected,

– if a dirty or scratched CD is played or
– when using poor-quality CD-Rs/CD-RWs or

if there is a problem with the original recording
device or application software.

Additional information

Precautions

On safety

• Should any solid objects or liquid fall into
the CD player, unplug it and have it
checked by qualified personnel before
operating it any further.

• Do not put any foreign objects in the DC
IN 4.5 V (external power input) jack.

On the CD player

• Keep the lens on the CD player clean and
do not touch it. If you do so, the lens may
be damaged and the CD player will not
operate properly.

• Do not put any heavy object on top of the
CD player. The CD player and the CD may
be damaged.

• Do not leave the CD player in a location
near heat sources, or in a place subject to
direct sunlight, excessive dust or sand,
moisture, rain, mechanical shock,
unleveled surface, or in a car with its
windows closed.

• If the CD player causes interference to the
radio or television reception, turn off the
CD player or move it away from the radio
or television.

• Discs with non-standard shapes (e.g.,
heart, square, star) cannot be played on this
CD player. Attempting to do so may
damage the CD player. Do not use such
discs.

On handling CDs

• To keep the CD clean, handle it by its
edge. Do not touch the surface.

• Do not stick paper or tape onto the CD.

• Do not expose the CD to direct sunlight or

heat sources such as hot air ducts. Do not
leave the CD in a car parked under direct
sunlight.

On headphones/earphones

Road safety

Do not use headphones/earphones while
driving, cycling, or operating any motorized
vehicle. It may create a traffic hazard and is
illegal in some areas. It can also be
potentially dangerous to play your headsets
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.

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.

The CD player is designed to stop the rotation of an MP3 CD
during playback to reduce the power consumption. The player is not
malfunctioning.

c

There are no MP3 files in the CD.

c A CD-RW from which the data has been erased is being used.
c The CD is dirty.

c Finalize the CD. (page 8)

c

The CD player is reading the information on the CD. The player is
not malfunctioning.

c

Adjust the volume of the CD player and the connected device.
(page 20)

c

If you use an MP3 file that was compressed with a transfer bit rate
setting other than “128 kbps,” this phenomenon may occur. We
recommend setting the bit rate to “128 kbps.”

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

• Maximum number of files: 511

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”,

“128 kbps”, 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 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.

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.
