Troubleshooting guide: Symptom Check if the disc was inserted correctly. Check if the disc is scratched or dirty. Check if there is condensation inside the player, and 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. Cannot play 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 characters for folder names and file names should be in compliance with the specifications. Check if the disc or the file is generated in an irregular format. This may occur depending on the variation or the setting of MP3/WMA writing applications or other text editing applications. 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 It takes a relatively long time before the music starts playing. Music cuts off or skips Skipping with high bit rate files Move immediately to the next song when playing. The songs do not play back in the desired order. Check if the disc is scratched or dirty. If there are many folder 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. 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 may occur with large quantities of data, such as for high bit rate data. 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. The playback order is the order in which the files were written by the writing software, so the files might not play in the desired order.
