■ USB memory functions
●Depending on the USB memory that is connected to the system, the
device itself may not be operable and certain functions may not be avail-
able. If the device is inoperable or a function is unavailable due to a mal-
function (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 discon-
nected and reconnected, format the memory.

●Compatible devices
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 (12 Mbps)
• File formats: FAT12/16/32 (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 correctly.
Items related to standards and limitations are as follows:
• Maximum directory hierarchy: 8 levels
• Maximum number of folders in a device: 999 (including the root)
• Maximum number of files in a device: 9999
• Maximum number of files per folder: 255
● 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 usi\
ng
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.

● 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.

282 3-2. Using the audio system
●MP3 and WMA playback
• When a device 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 device 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.
• Microsoft, Windows, and Windows Media are registered trademarks of Microsoft Corporation in the U.S.A. and other countries.
