Troubleshooting guide:
Symptom Cause and Countermeasure
Cannot play
Check if the CD/DVD/USB device was inserted correctly.
Check if the CD/DVD 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 player will play correctly after it returns to the normal temperature.
If there is a mixture of music CD files (CD-DA data) and compressed audio files on a CD, only the music CD files (CD-DA data) will be played.
Files with extensions other than “.MP3”, “.WMA”, “.AAC”, “.M4A” or “.AA3” cannot be played. In addition, the character codes and number of charac-
ters for folder names and file names should be in compliance with the specifications.
Check if the disc or file is generated in an irregular format. This may occur depending on the variation or the setting of the compressed audio file writ-
ing application 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 CD/DVD/USB device is protected by copyright.
Poor sound quality Check if the CD/DVD is scratched or dirty.
It takes a relatively long time
before the music starts
playing. If there are many folders or file levels on the CD/DVD/USB device, 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 playing If an unsupported compressed audio file has been given a supported extension like “.MP3”, or when play is prohibited by copyright protection, 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 desired order.
Random/Shuffle may be active on the audio system or on the USB device.
