  By "take apart" you mean removing the front panel PCBs, right?
Opening the case is no big deal, though you have to be a little
careful of some thin metal tabs near each end.  I have a post in the
archives with more about this.  The archives may also contain some
comments about the knobs; search for something like "blue panel" or
"beta panel" or some such...or "aurora", though that will yield many
many hits.  There was discussion about how difficult it would be to
affix one of the pre-release panels.

  Anyway, some photos of the guts of the thing may be found here:

  I don't recall there being a battery but my memory is hazy and my pictures
are not really very good.  :)
