Almost every time I go away from the BC for a while, say, a day or more, when I return to it and press any button, I get a static sound and hear nothing else. The only way to fix this is to take out the batteries and put them in again. Anybody else have this problem? Hope I don't have to send it to be fixed. A couple of other strange problems are: 1. When I try to play the BC with advance mode on, after a while I get an error message and am asked to reset the unit. I can't write down the message; too fast. 3. If I put mp3s on a flash card through a flash card reader, sometimes the BC won't be able to read them. I just get an error message. I have no trouble playing the files straigh from the card reader. Thanks for your assistance. Sharon
