●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 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.
CAUTION
■Caution while driving
Do not connect USB memory or operate the controls.

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.
