The manual for working with the recorder is most confusing,as it jumps from one thing to a diff subject,when you go from recording to transfer to pc threw the fat or wave, on one page it says to open usb first on diff page says to open after all songs have been saved and backed up,also says all songs can be sent at 16 bit to pc as mono but have to use pc to format them that don't work you will cause all songs to delete. i get a recording about one out of three trys as pc don't recognize usb conn, manual should start at number 1 and go threw from there instead of starting over with number 1 on ever page.
