I think I allowed myself to get confused because of an earlier post,
to wit:
"You should probably coordiante with Joerg on this ... the remote
leg/arm electrode seems to be integral to the design. And shielded
cables sound highly desirable. (that is, it sounds to me like ur
thinking in a bit different direction than hardware specs)."
I had previously assumed that the "remote leg/arm electrode" was a
reference electrode that could be replaced with an Au1-Au2 linked
hookup, and didn't see the cable issue as relevant to the electrodes,
so this posting led me to conclude that I was really not
understanding something.
