Operating Tips for AAC

AAC stands for Advanced Audio Coding, which is standardized voice compression established by the ISO *1 working group (MPEG). Audio data can be created and stored at a higher compression ratio than MP3.

This unit plays files with the extensions (.aac/.m4a/.wav *2 ) as the AAC files.

CAUTION Do not use an audio fi le extension on fi les other than audio fi les. In addition, do not change the audio fi le extension.

Otherwise, the unit will not recognize the fi le correctly resulting in noise or a malfunction.

• AAC files written under specifications other than the indicated specification may not play normally or files or folder names may not display correctly.
• The file extension may not be provided depending on the computer operating system, version, software, or settings. In this case, add the file extension “.aac ”, “.m4a”, or “.wav *2 ” to the end of the file name, and then write it to the memory.
