The Kawai & Teisco Analog Synths Group

Hi everyone! 

I just came home from the Goodwill with a SX-240. I plugged it in 
and it does make sound. A kind of boring patch, but it seems to 
work!

I downloaded the user manual from Kawai so I have lots of 
reading and tinkering to do.

Questions-

How do I get inside this thing? I'd really like to check that the 
battery is O.K. and (I guess) get a replacement. Plus, I love 
seeing the guts of my electronic junk.

One of the switch covers is missing. Are these (even if the wrong 
color) available anywhere?

I was going to ask about the little reset hole in back. I'll just try it 
sans handholding.. 

Well, off to spend quality time with the manual. God, I hope it's 
easier to program than my CZ-101...
