may increase or decrease irregularly, but this is normal.
When the battery is low, the icon starts blinking, and in about 30 minutes the power goes off
automatically.
This icon indicates the memory usage while the player is stopped in the MP3 Player mode.
If the built-in memory is 128Mbyte, 1 segment of the icon indicates about 21MByte (128Mbyte
÷ 6).
This icon becomes animated while playback.
When tag (ID3V1, ID3V2) is available, this icon is changed to Disk and the Artist + Album
information is displayed. When the display setting is ‘Filename’, or the tag does not include the
Artist information, this icon is changed to Folder and the folder name is displayed. When the le
