have not been changed), the USB memory will resume playing from the
same point it was last used.
Depending on the USB memory that is connected to the system, certain
functions may not be available. Disconnecting the device and reconnecting
it once again may resolve some malfunctions.

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 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.
MP3 file compatibility

File names

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.

tags.
(The number of characters is based on ID3 Ver. 1.0 and 1.1.)

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 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 con-
tents 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 depending on the status of the encod-
ing and the file format, poor sound quality or noise at the start of play-
back may result. In some cases, playback may not be possible at all.
• Microsoft, Windows, and Windows Media are registered trademarks of
Microsoft Corporation in the U.S.A. and other countries.
