GENERAL INFORMATION
Maintenance
� Do not touch the lens A of the player. � Do not expose the unit, batteries or discs to humidity, rain, sand or excessive heat (caused by heating equipment, or direct sunshine). � You can clean the player with soft, slightly dampened and lint-free cloth. Do not use any cleaning agents, as they may be corrosive. � To clean the CD, wipe it in a straight line from the center toward the edge using soft, lint-free cloth. � Never write on a disc or attach a sticker to it. � Discs and lens may cloud over when the unit is moved suddenly from cold to warm surroundings. Leave the player in a warm environment until the moisture has evaporated. � Active mobile phones in the vicinity may cause malfunctions. � Avoid dropping the unit as this may cause damage.

GENERAL INFORMATION
General MP3 information
MP3 music �les The music compression technology MP3 (MPEG Audio Layer 3) reduces the digital data of an audio CD signi�cantly while maintaining CD-like sound quality. With MP3 you can record up to 10 hours of CD-like music on a single CD-RW. How to get music �les Either download legal music �les from the Internet to your computer hard disc or create them from your own audio CDs. For this, insert an audio CD into your computer's CD-ROM drive and convert the music using appropriate encoder software. To achieve good sound quality, a bit rate of 128 kbps or higher is recommended for MP3 music �les. How to organize music �les In order to easily handle the large number of music �les on a CD-ROM, you can organize them in folders ("albums"). The tracks of an album will be played in alphabetical order. If you want to arrange them in a certain order, let the �le names start with numbers. For example: 001-EWORLD.MP3 002-FIRESTARTER.MP3 003-DEEP.MP3 Albums will be arranged in alphabetical order, but subfolders (albums within another album) will be played immediately after the album in which they are located. Albums without MP3 �les will be skipped. If there are MP3 �les which you did not put into an album, you will �nd them in the album VARIOUS with album number 0. VARIOUS is the �rst album that will be played.
