Vanark, well, Chris pointed out the possible problem and I just moved the switch the rest of the way
I didn't want to force it but when he mentioned that possibility, a little low watt light bulb DID come on!
Dark train, with the STC-9000 turned upside down with the battery case opened, yeah, moving the switch left would turn it off, at least on mine. But mine's marked inside. Not sure about the 9100. PM Chris to be sure. I'm taping four bands tonight at a mini-festival here at home.
My son is also going to attempt to do a live webcast on synchronicitylive.com beginning at 6 p.m. It's the Urban Echo show so check it out if you can to see if it works. Thanks for the help. rWc3523
