Turn off the Boss Micro BR with the slide switch on the left-hand edge of the component.
Insert the plug on one end of the USB cable that comes with the Boss Mirco BR into the USB port on the left-hand edge of the device. The plug inserts in one direction only, so do not attempt to force it in the jack.
Plug the other end of the cable into any free USB port on the computer and wait for the "New Hardware Detected" message to display on the monitor.
Double click the "New Hardware" message to open the audio software on the computer, then click the "File" tab, select "Open" and highlight the desired digital file on the Boss Micro BR.
Double-click the name of the file, then click "Play" on the computer audio software to play back the digital recording.
