until the beep sound is heard (about 2 to 5 seconds) to turn on the Digital Audio Player.
The LED lamp lights up and the Digital Audio Player is turned on, then the playback starts.
When the playback position is memorized, playback starts from the memorized position. (See "To stop playback".)
NOTE:
When the Digital Audio Player has no playable music files, it automatically turns off immediately after turning on.
It may take a longer time to read out playlists before playback each time you connect the Digital Audio Player to PC.
You may hear a little sound distortion and/or noise depending on the music type and the bitrate of the file. In this case, change the format of the music file into MP3 or make a music file with low bitrate again.
The playback order of the music files may be different from the order on the PC. To play back the music files in the desired order, see "Playing back with playlist".
