USB MP3/WMA概述
MP3概述
MP3(MPEG Audio Layer 3)是一种包含音
乐压缩技术。
本产品能播放CD-ROM，CD-R或CD-RW光
碟上的MP3文件。
主机能读以ISO9660格式记录的MP3文件，
但是不支持MP3数据以捆绑方式记录的MP3
文件。
主机不能读取".MP3"扩展名的非MP3文件,
可能听到一些噪音。
在手册里，PC术语中的“.MP3文件”和
“文件夹”分别称为“曲目”和“唱片集”。
支持最大的目录深度为8层，包括根目录支
持每个光碟最大的文件数量是512。
主机可能不按照曲目号码顺序播放曲目。
当一张光碟同时包含音频文件和MP3文件时，
主机仅播放音频文件。
当播放8kbps或VBR*光碟时，当前播放时间
可能无法正常显示，扫描播放功能也可能无
法正常使用。
*VBR：可变比特率。
创建包含MP3文件的CD-R或CD-RW
的注意事项
为了享受高质量的音乐，我们建议转换MP3
时使用44.1KHz的取样率和128Kbps的固定
比特率。
每张碟片不要存储超过512个MP3文件。
遵从ISO9660格式，允许的最大目录深度为8
层，包括根目录(文件夹)。
播放CD-R光碟时，只有已经终结刻录的光碟
才可以播放。
确保MP3 CD-R或CD-RW刻录时，应作为一
个数据光碟格式而不是作为一个音频光碟格
式来刻录。
不应将非MP3文件或不需要的文件与MP3文
件一同写入光碟，否则在开始播放MP3文件
之前会花费很长一段时间。
一些CD-R或CD-RW媒体，数据烧写可能达
不到他们的生产质量，这样的话数据不能被
正确的读取，所以建议使用高质量的CD-R或
CD-RW光碟。
支持版本为1.XX和2.XX ID3标签，多达16个字
符显示歌曲标题、唱片集标题和艺术家名字。
(不支持中文显示)
注：主机有可能不会按照您刻录的顺序去播放
曲目。

Safety Information
PRECAUTIONS
• Use only in a 24-volt DC negative-
ground electrical system.
• Disconnect the vehicle's negative battery
terminal while mounting and connecting
the unit.
• When replacing the fuse, be sure to use
one with an identical amperage rating.
Using a fuse with a higher amperage
rating may cause serious damage to the
unit.
• DO NOT attempt to disassemble the unit.
Laser beams from the optical pickup are
dangerous to the eyes.
• Make sure that pins or other foreign objects
do not get inside the unit,they may cause
malfunctions, or create safety hazards
such as electrical shock or laser beam
exposure.

USB MP3/WMA Overview
Note on Mp3
• MP3 is short for MPEG Audio Layer 3
and refers to an audio compression
technology standard.
• This product allows playback of MP3 les
on CD-ROM, CD-R or CD-RW discs.
• The unit can read MP3 les 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 le that has
a le extension other than ".mp3".
• If you play a non- MP3 file that has the
" .mp3 " extension, you may hear some
noise.
• In this manual, we refer to what are called
"MP3 le" and "folder " in PC terminology
as "track" and "Album," respectively.
• Maximum number of directory level is
8, including the root directory. Maximum
number of les and folders per disc is 256
.
• The unit may not play tracks in the order
of Track numbers.
• The unit plays only the audio Tracks if a
disc contains both audio tracks and MP3
les.
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. ID3 TAG
version 1.x is required.
• Note that the unit may not play Track in
the order that you wrote them to the disc.

• When playing a disc of 8kbps 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
Note on creating your own CD-Rs or
CD-RWs containing MP3 les
• To enjoy high quality sound, we
recommend converting to MP3 files with
a sampling frequency of 44.1 kHz and a
xed bit rate of 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
nalized.
• 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 les on
the disc otherwise it takes a long time until
the unit starts to play MP3 les.
• With some CD-R or CD-RW media, data
may not be properly written depending on
their manufacturing quality .
