Is this BCF2000 defective?

[mojogil]

I picked up a used BCF2000 locally. I got it home, fired it up, and the screen displays "OC C". Not sure what that means, I can't find anywhere in the docs that tells me what it means. Nothing I do can get it to move from that display. My computer recognizes it when I plug it in. Any ideas?
Thanks,
Gil

It's in Mackie mode. I can't remember how to get it back, but it's in the instructions.

Holding each of the buttons below the rotary controls when switching the unit on selects which control protocol the BCF2000 uses.

Yes, that is correct. Holding the first button while powering on put it back to B-control.
