itself may not be operable and certain functions may not be available. If the
device is inoperable or 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.
●If the USB memory still does not begin operation after being disconnected and
reconnected, format the memory.

USB memory that can be used for MP3 and WMA playback
●Compatible device formats
The following device formats can be used:
• USB communication formats: USB2.0 FS (12mbps)
• File formats: FAT16 /32 (Windows)
• Correspondence class: Mass storage class
MP3 and WMA files written in any format other than those listed above may not
play correctly, and their file names and folder names may not be displayed cor-
re ct l y.
Items related to standards and limitations are as follows:
• Maximum directory hierarchy: 8 levels

●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 and WMA playback
• When a USB memory containing MP3 or WMA files is connected, all files in the USB memory 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 memory is connected and the audio source is changed to USB memory mode, the USB memory will start playing the first file in the
first folder. If the same USB memory is removed and reinserted (and the
contents have not been changed), the USB memory 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 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.
