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.

USB 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 (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 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 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.

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 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
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.
CAUTION
Caution while driving
Do not connect USB memory or operate the controls.
NOTICE
To prevent damage to USB memory
Do not leave USB memory in the vehicle. The temperature inside the vehi-
cle may become high, resulting in damage to the player.
Do not push down on or apply unnecessary pressure to the USB memory
while it is connected as this may damage the USB memory or its terminal.
Do not insert foreign objects into the port as this may damage the USB
memory or its terminal.
