Error, I'm an audio guy who just got a Sony UVM 100 for a back up front of house corporate show live feed cam. I got the same error and the LCD didn't function. This is typical in musical keyboards when the lithium button battery dies. The one on the cam was so asscessable, I figured it had to have something to do with it. Tested it, it was dead. I replaced it an the error went away immediately and it all works fine. Just though someone would like to know
