TIPS FOR OPERATING THE AUDIO SYSTEM
● AAC/AAC+ v2/MP3/WMA files in folders up to 3 levels
deep can be played. However, the start of playback
may be delayed when using USB memory device
containing numerous levels of folders. For this reason, we
recommend creating USB memory device with no more
than 2 levels of folders.

computer and AAC/AAC+ v2/MP3/WMA encoding
software that were used.
