Wow! I thought I wouldn't be able to find manual for such rare equipment like KM2000E. And here it is! Thanks for fast service!

Essential for popping the top open and cleaning and replacing what needs repalced. One note: the Ornamental Panel is attached with some adhesive as well as screws and faders so don't be shy about prying it open.
