Symptoms

Remedies/Causes

MP3/WMA playback

•  Tracks are not played back in the order you 

have intended.

The playback order is determined when the files are 

recorded.

•  The elapsed playing time is not correct.

This sometimes occurs during playback. This is caused by 

how the tracks are recorded on the disc.

•  The correct characters are not displayed (e.g. 

album name).

This unit can only display alphabets (upper case), 

numbers, and a limited number of symbols.

USB device playback

•  Noise is generated.

The track played back is not an MP3/WMA track. Skip to 

another file. (Do not add the extension code <.mp3> or 

<.wma> to non-MP3 or WMA tracks.)

•  “READING” keeps flashing on the display.

•  Readout time varies depending on the USB device.

•  Do not use too many hierarchy, folders, and empty 

folders*.

•  Turn off the power then on again.

•  Reattach the USB device again.

*  Folder that is physically empty or folder that contains 

data but does not contain valid MP3/WMA track.

•  Tracks/folders are not played back in the 

order you have intended.

The playback order is determined by the write-in time 

stamp. The first track/folder written into the USB device 

will be the first  track/folder for playback.

•  “NO FILE” flashes on the display.

•  “NO USB” appears on the display.

•  The unit cannot detect the USB device.

•  Attach a USB device that contains tracks encoded in an 

appropriate format.

•  Reattach the USB device again.

•  “READ” and “FAILED” appear alternately on 

the display.

The total number of tracks could not be accessed properly.

•  Correct characters are not displayed (e.g. 

album name).

This unit can only display alphabets (upper case), 

numbers, and a limited number of symbols.

•  While playing a track, sound is sometimes 

interrupted.

The MP3/WMA tracks have not been properly copied into 

the USB device.

Copy MP3/WMA tracks again into the USB device, and try 

again.
