I just got my 'new' MZ-R90 through my mail, which I won off Ebay. But when I pushed the play button nothing appeared on the display. I listened to music, but the display wasn't showing anything. Well, now half an hour later it does show something. It shows everything, but the display goes on and off and on and off all the time. So, is this because the MZ-R90 hasn't been used for some time and it'll re-appear within a few days properly? Or maybe it has something to do with the fact I'm using just a AA battery and not the gumstick as there isn't a adapter with it? Hopefully you guys can help me out.
