<HTML>Listees and Listers, I don't do too much work on pianos with disc systems in them, but I do t= une them occasionally, because some of the people who install them don't tun= e.  Anyway, I get to a customer's house, and she wants me to see if I c= an add another speaker to her Pianomation 2000CD+ system so that the accompa= nying 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 4= 0--it's maximum output.  Efforts with both the remote and the buttons o= n the unit itself proved futile.  As soon as I released whichever butto= n I was pushing, it would go back up to 40.  I could get no other displ= ay. 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 an= d 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 cou= ld read the remote signal. I finally  figured it out, and it was painfully simple.  Can a= nyone figure this out? Dave Stahl</HTML>
