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 available. If the
device is inoperable or a function is unavailable due to a malfunction (as
opposed to a system specification), di sconnecting 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.■

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 (MPEG1 AUDIO LAYERII, III, MPEG2 AUDIO LAYERII, III,
MPEG2.5)

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 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).
