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 by using MP3
compression.
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. ●

iPod will resume play from the same point in which it was last used.●
Depending on the iPod that is connecte d to the system, certain functions may
not be available. If a function is unavailable due to a malfunction (as opposed to
a system specification), disconnecting the device and reconnecting it once
again may resolve the problem. ●

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 th e file check finish more quickly, we
recommend that you do not include any files other than MP3 or WMA files
or create any unnecessary folders.
• When the USB device is connected and the audio source is changed to
USB memory 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.●
Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and WMA
files, they will be skipped (not played).●
Playback
• To play MP3 files with steady sound quality, we recommend a fixed bit rate
of at least 128 kbps and a sampling frequency of 44.1 kHz.
• There is a wide variety of freeware and other encoding software for MP3
and WMA files on the market, and depend ing on the status of the encoding
and the file format, poor sound quality or noise at the start of playback may
result. In some cases, playback may not be possible at all.
