from L to R looking at the panel, this is how mine stays set: power=ON, MIC setting, 24/48 phantom, -35 sens, no rolloff, 0 gain
All the runtime you need off a set of 1800mAh powerex's, but I've never really tested it to be sure. It ran an entire allmans show + opener last summer without flinching- I'm sure it would go longer than that. Contrary to popular belief, I'd just run it off internals since the power connection is in a weird place and is non-locking. Just make sure you get the sled seated in there the right way or it'll come back to bite you.
Marc might be able to help you out a little more since he ran it with the 4022s, but there ain't that much to screw up.

edit: spelling
edit 2: it's really sensitive, at the lowest gain setting it peaked out irregularly (kind of how you want a UA-5 to peak out if that makes any sense) FOB at panic running the 63 caps. I think the DPAs don't drive the signal that hard so you should be OK, but you might need to think about some attenuators if you think that will be a problem, especially for louder acts (mule and the truckers come to mind)
