Listees and Listers,

I don't do too much work on pianos with disc systems in them, but I do tune 
them occasionally, because some of the people who install them don't tune.  
Anyway, I get to a customer's house, and she wants me to see if I can add another 
speaker to her Pianomation 2000CD+ system so that the accompanying music will 
be in stereo.  If I had done my research beforehand, I would have saved 
myself a bit of time and grief, because I found out later that they can't play in 
stereo--channel 2 is used to drive the player unit.

I turned the player on, and it wasn't making any sound, so I turned the 
volume up a little.  Unfortunately, the volume went all the way up to 40--it's 
maximum output.  Efforts with both the remote and the buttons on the unit itself 
proved futile.  As soon as I released whichever button I was pushing, it would 
go back up to 40.  I could get no other display.

I called my friend who installs these to see if he could help.  We ran 
through a few simple tests that didn't work, including turning it off and unplugging 
it to let the capacitors drain, then turning it back on.  I looked to make 
sure the window was lined up correctly so that the unit could read the remote 
signal.

I finally  figured it out, and it was painfully simple.  Can anyone figure 
this out?
