·
technology standard.
This product allows playback of MP3 files on CD-ROM, CD-R or CD-RW discs.
·
The unit can read MP3 files written in the format compliant with ISO 9660.
·
However it does not support the MP3 data written by the method of packet write.
The unit can not read an MP3 file that has a file extension other than ".mp3"

noise.
In this manual, we refer to what are called "MP3 file" and " folder" in PC
·
terminology as " track " and " album ", respectively.

·
number of files and folders per disc is 256.
The unit may not play tracks in the order of Track numbers.

·
MP3 files.
When playing a disc of 8 kbps or "VBR", the elapsed playing time in the display

window will not be correct and also the intro play may not function properly.
" VBR ":Variable Bit Rate.
The unit supports the playback of WMA files. The playback of ID3 tags for WMA
·
format is not guaranteed, it depends on versions and availability of Cyrillic
alphabet.
WMA (Windows Media Audio) -music data compression format, created by
·
Microsoft Corporation. This format uses coding algorithm for compression of
initial audio-record, greatly decreasing the file size, but, saving the good sound
quality even when the bit rate is low (for example, 64 Kbit/s).
Remember that the unit may not play the tracks in order they are written on disc.
·
Notes on creating your own CD-R or CD-RW containing MP3 files:
·
To enjoy high quality sound, we recommend converting to MP3 files with a
sampling frequency of 44.1 kHz and a fixed bit rate o f 128 kbps.
·
DO NOT store more than 256 MP3 files per disc.
For ISO 9660 - compliant format, the maximum allowable depth of nested
·
folders is 8, including the root directory (folder).
When CD-R disc is used, playback is possible only for discs, which have been
·
finalized.
Make sure that when MP3 CD-R or CD-RW is burned that it is formatted as a
·
data disc and NOT as an audio disc.
You should not write non-MP3 files or unneeded folders along with MP3 files
·
on the disc otherwise it takes a long time until the unit starts to play MP3 files.
With some CD-R or CD-RW media, data may not be properly written depending
·
on its manufacturing quality. In this case, data may not be reproduced correctly.
High quality CD-R or CD-RW disc is recommended.
Up to 16 characters are displayed for the name of an Album or a Track. ID3TAG
·
version 1.x is required.
Note that the unit may not play Tracks in the order that you wrote them to the
