I can't give you a step by step cause my H340 is busy, but I belive you go into the folder containing all your music and then press the button that brings up the menu for playlist options, either the "*" or the "AB".(Its been a while cause i havent had to create a new list with all my songs on random
) and select create playlist(it will probably put the playlist one folder up from there). Then you open that playlist and turn shuffle on and turn random on by going into the playmode menu by pressing one of those buttons again. I hope you can figure it out, I rarely ever use those options so I am relying on my ,not so great, memory.
