Troubleshooting guide
Symptom Cause and Countermeasure
Cannot play
Check if the disc was inserted correctly.
Check if the disc is scratched or dirty.
Check if there is condensation inside the player. If there is, wait until the condensation is gone (about 1 hour) before using the player.
If there is a temperature increase error, the CD player will play correctly after it returns to the normal temperature.
If there is a mixture of music CD files (CD-DA data) and MP3/WMA files on a CD, only the music CD files (CD-DA data) will be played.
Files with extensions other than “.MP3”,“.WMA”, “.mp3” or “.wma” cannot be played. In addition, the character codes and number of char-
acters for folder names and file names should be in compliance with the specifications.
Check if the finalization process, such as session close and disc close, is done for the disc.
Check if the disc is protected by copyright.
Poor sound quality
Check if the disc is scratched or dirty.
Bit rate may be too low.
It takes a relatively long
time before the music
starts playing.
If there are many folders or file levels on the MP3/WMA disc, or if it is a multisession disc, some time may be required before the music
starts playing.
Music cuts off or skips
The writing software and hardware combination might not match, or the writing speed, writing depth, writing width, etc., might not
match the specifications. Try using the slowest writing speed.
Skipping with high bit
rate files
Skipping may occur with large quantities of data, such as for high bit rate data.
Moves immediately to
the next song when play-
ing
When a non-MP3/WMA file has been given an extension of “.MP3”, “.WMA”, .“mp3”or “.wma”, or when play is prohibited by copyright
protection, there will be approximately 5 seconds of no sound and then the player will skip to the next song.
Songs do not play back
in the desired order
The playback order is the order in which the files were written by the writing software. Therefore, the files might not play in the de-
sired order.
