■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 available.

  If the device is inoperable or a function is unavailable due to a malfunction (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 disconnected and reconnected, format the memory.

■Error messages for USB memory

■USB memory

• Compatible devices
  USB memory device that can be used for MP3, WMA and AAC playback.
• Compatible device formats
  The following device format can be used:
  • USB communication format: USB2.0 HS (480 Mbps) and FS (12 Mbps)
  • File system format: FAT16/32 (Windows)
  • Correspondence class: Mass storage class
    MP3, WMA and AAC files written to a device with 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: 3000 (including the root)
  • Maximum number of files in a device: 9999
  • Maximum number of files per folder: 255
• 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.

  • Compatible channel modes: 1 ch and 2 ch
• File names
  The only files that can be recognized as MP3/WMA/AAC and played are those with the extension .mp3 or .wma.
• ID3, WMA and AAC 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 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 and AAC files is connected, all files in the USB memory device are checked. Once the file check is finished, 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 playing the first file in the first folder. If the same device is removed and reconnected (and the contents have not been changed), the USB memory 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.
