front panel. Then, move one button to the left. This is the “play/pause”
button. With the “play/pause” button, you can easily play audio files
registered in the play list. If there are no files that have been registered
in the play list, the Braille Sense U2 will display the message, “There are
no items to display.” You have to add a file to the play list before it can
be played. If there is more than one file in the play list when you press
the “play/pause” button, the Braille Sense U2 will start playing all the
files in the list one after another. If you press the “play/pause” button
again while a file is being played, the playback will be paused. If you
want to resume playing, press the button again. If you press the
“play/pause” button while you are in the “record” dialog box, the sound
that was recorded most recently will be played back to you.
9.1.2 Next button and previous button
These buttons have a triangular shape. The “previous” button is the first
button from the left on the front panel, and it points to the left. The “next”
button is the button that is farthest to the right on the front panel, and it
points to the right. If you press the “next” button, the next file in the play
list will be played, and pressing the “previous” button will play the
previous file. If you press one of these buttons while an audio file is
being played, the Braille Sense U2 will stop playing the current file, and
jump to the previous or next file (depending on which button you press)
in the play list, and start playing it. If you press the “next” button (while
the last file in the list is being played), or the “previous” button (while the
first file in the list is being played), it will have no effect, as the Braille
Sense U2 will not stop playing the current file.
9.1.3 Record Button
The “record” button has a circular shape, and is used to record sound
using the built-in or an external microphone. The “record” button is
located directly to the right of the “previous” button. To use this button to
record sound, you should be either in the “Media Player,” or in the
“program” menu. If you press the “record” button once, the Braille Sense
U2 will open the “record” dialog box. If you press the “record” button
