  You may nd that although you have added les to either an SD card 
or a USB memory device, the MP-23  is unable to identify the les 
and may report "No data". In this event, we recommend that the card 
or memory should be reformatted in your computer. Before doing this, 
you should copy all les and folders on the card to your computer for 
temporary storage. After the format process is completed, then you 
should copy the les back again. If the MP-23 is still unable to read 
the les, then it is likely that your SD or USB memory device is not 
completely compatible in some way.
