When the radio skips from one folder to another, the

ignored during this period) and a maximum of three
seconds. When you reach the final track in the last folder
and turn the ROTARY knob clockwise, the radio will
advance to the first track in the first folder on the USB

turn the ROTARY knob counterclockwise, the radio will
advance to the last track in the last folder on the USB
device.
Forward/Reverse Folder
When you push the memory 1 button, the radio will
advance to the first track in the next folder containing
audio files, if you push button 2, the radio will return to
the first track in the previous folder containing audio
files.
When this operation is complete, the display shows the
name of the selected folder. If you push any of these
buttons again quickly, the name shown is updated as you
select folders on the USB device. While the track is being
selected, that is, when you push buttons 1 or 2 quickly,
the information contained in ID3 tag is not processed. If
you do not push and hold 1 or 2, the track is selected, the
ID3 tag is processed and the music will start playing.
In this case, the display will continue showing the name
of the selected folder for two seconds and then return to
the default display defined by the DISP function.
