George's recommended editorial changes read (in part):

>    c) not respond to a selection service until a hard reset occurs."

I understand he included item (a) so the list looks like the three items in the
previous list, but a reading of items (b) and (c) alone is sufficient to specify
that the power condition (or anything else) cannot change until a hard
reset occurs. I suggest that item (a) can be deleted and the other two items
re-lettered as (a) and (b).
