MP3 and WMA files
●
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.
Files can be compressed to approximately 1/10 of their original size using MP3 com-
pression.
WMA (Windows Media Audio) is a Microsoft audio compression format.
This format compresses audio data to a size smaller than that of the MP3 format.
There is a limit to the MP3 and WMA file standards that can be used and to the media/
formats on which the files are recorded.

File names
●
The only files that can be recognized as MP3/WMA and played are those with the
extension .mp3 or .wma.
ID3 and WMA tags
●
ID3 tags can be added to MP3 files, making it possible to record the track title, artist
name, etc.
The system is compatible with ID3 Ver. 1.0, 1.1, and Ver. 2.2, 2.3, 2.4 ID3 tags. (The
number of characters is based on ID3 Ver. 1.0 and 1.1.)
WMA tags can be added to WMA files, making it possible to record the track title and
artist name in the same way as with ID3 tags.
MP3 and WMA playback
●
• When a device containing MP3 or WMA files is connected, all files in the USB
memory device are checked. Once the file check is finished, the first MP3 or WMA
file is played. To make the file check finish more quickly, we recommend that you do
not include any files other than MP3 or WMA files or create any unnecessary fold-
ers.
• When the USB device is connected and the audio source is changed to USB mem-
ory mode, the USB device will start playing the first file in the first folder. If the same
device is removed and reinserted (and the contents have not been changed), the
USB device will resume play from the same point in which it was last used.
