USB memory functions

●

Depending on the USB memory device 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 may resolve the problem.

●

If the USB memory device still does not begin operation after being discon-
nected and reconnected, format the memory.

MP3, WMA and AAC 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. 

AAC is short for Advanced Audio Coding and refers to an audio compression
technology standard used with MPEG2 and MPEG4.

MP3, WMA and AAC file and media/formats compatibility are limited.

MP3, WMA and AAC playback

• When a device containing MP3, WMA and AAC files is connected, all

files in the USB memory device are checked. Once the file check is fin-
ished, the first MP3, WMA and 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 and AAC files or create any unnecessary folders.

• When a USB memory device is connected and the audio source is

changed to USB memory mode, the USB memory device will start play-
ing the first file in the first folder. If the same device is removed and
reconnected (and the con- tents have not been changed), the USB mem-
ory device 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.

• Microsoft, Windows, and Windows Media are the registered trademarks

of Microsoft Corporation in the U.S.A. and other countries.
