hey people out there... please help me. i'm very down now. so here's the problem: i'm using a mz-n910. everything is fine when i have it plugged to the pc and in the cradle. so i can record music from the pc to the md fine. but when i try to charge the battery by pressing the stop button or plug the dc into the md without having it in the cradle or whatever, when i have the dc plugged in to the main unit i can press any key, don't matter which, and the display is flashing saying pc->->md. so i can't record, change settings or whatever. please help me i don't know what to do. thank you a lot
