burning standard.
To obtain the best acoustic quality pos-
sible, select the lowest burning speed.
The MPEG1 and MPEG2 standards

Transmission speeds between 32 and
320 kbits/s and scans between 16 kHz
and 48 kHz are accepted.
To display the title information (the
name of the artist, the title of the album,

What is the MP3/WMA fi le format?
MP3 is the abbreviation of MPEG-1 Audio
Layer 3 and MPG is the abbreviation of
Motion Pictures Experts Group, a digital
video data compression standard used on
media such as video CDs.
The MP3 compression reduces the
number of bytes in a song by eliminat-
ing the long sound waves in the range of
frequencies which are imperceptible to
the human ear, so producing high quality
audio fi les with a low volume of data.
This compression divides the size of
the content of a conventional audio CD
by approximately 10, which means that
the content of 10 audio CDs can be re-
corded onto a single CD-R or CD-RW.
WMA is the abbreviation of Windows
Media Audio, another audio data com-
pression standard offered by Microsoft.
It can be used to create and save audio
fi les at a compression rate higher than
that of the MP3 format.
Windows Media and Microsoft Corpo-
ration are trademarks registered in the
United States and/or other countries.
When the MP3/WMA CD is
inserted in the player, playing
of the tracks is automatic.

The tracks cannot be recorded
onto the music server.
You can play up to 8 levels,
255 folders and 400 fi les
maximum.
