I have a GE Advantium convection oven. I try to use it and it says "Control panel Locked" How do I clear it? Hope you can answer my question.

Have you tried unplugging it for 2 minutes?

Press and hold CLEAR/OFF for about 3 seconds to unlock the control. I just got the manual. You can get it here: http://dl.dropbox.com/u/8010163/GE_Advantium_Oven.pdf
Hope this helps.
