New audio will not load when memory stick is inserted.

1. If the status light does not start blinking, remove the memory stick and reinsert it.

2. If the status light is blinking, but never stops, make sure the file is an mp3 encoded at 128kbps mono at 44.1khz by an audio encoder, as simply renaming a .wma or .m4a file will not change its actual format.

3. Make sure that your audio file has any album art removed before reloading the audio to the unit.

4. Make sure that the name of the audio file contains no special characters as stated in the manual of the product.
