press down gently until the disc clicks into place.
The disc may be incompatible with the player. This player supports CD-audio, CD-
R/RW, and MP3 CD discs.
Homemade discs must be finalized and mastered with the ISO/Joliet file system.
I cannot play MP3s.
If you have a disc with MP3 files, there are several reasons it may not play even if you
can see the files on a computer. Make sure to do the following when making an MP3
CD:
1) Make sure that there are only MP3 files on the disc. If there are any other
types of files, the disc may not play.
2) Make sure that you have MP3 files and not a different type of digital music
file. On your computer, right-click the file and select Properties (or Get Info)
to view info about the file.
3) Make sure that you finalize the disc after burning.
4) Make sure that the disc is made with the ISO/Joliet file system.
There are many computer programs that can make CDs. Your computer may already
have one. Please refer to the instructions provided by the computer program author
to learn more about making CDs.
MP3 playback is skipping
or otherwise distorted.
MP3 files encoded at a very high or very low sample rates may not play properly. (A
typical CD-quality file is encoded at 192 Kbps and 44,100 Hz. Try playing a different
file).
On occasion, an MP3 file may become corrupt while it is stored on a computer. Try
downloading the file again or re-encoding the file if you made it yourself. You may
also try playing a different file.
Fast-forward and reverse
are erratic with MP3 files.
MP3 files use dynamic compression to store music. Music is complex and different
passages of music may require more or less compression. When a player scans
quickly through an MP3 file, the uneven compression will appear as erratic jumps and
skips. This is normal for an MP3 player.
