Just got this Manual downloaded... Scan is PERFECT! This is EXACTLY what I needed. However, please update your site info to state that it may take more than \"a few hours\" to have the download available after payment - - - I had to wait 4 days, in my case. Otherwise, I am very happy with this!!! Thanks! --- User-Manuals.COM comment We\'re sorry for delay, we had major problem with our download server, but all is ok now and downloads works as previous.

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.
