ID3 tags can be added to MP3 files,

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.
AAC tags can be added to AAC files,
making it possible to record the track
title and artist name in the same way as
with ID3 tags.
● MP3, WMA and AAC playback
• When a device containing MP3, WMA
or AAC files is connected, all files in
the USB memory device are checked.
Once the file check is finished, the first
5-5. Using an external device
MP3, WMA or AAC file is played. To
make the file check finish more
quickly, we recommend that you do
not include any files other than MP3,
WMA or AAC 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 memory
will resume play from the same point
in which it was last used.
●
Extensions
If the file extensions .mp3, .wma and
.m4a. are used for files other than MP3,
WMA and AAC 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,
WMA and AAC 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.
