Thanks for the reply and the information - you, and some others, prove that there are some helpful people on this site! Perhaps Dan was having a very bad day, don't tell him that the full moon won't be until late February. On second thought perhaps he should be told so that he'll have something to look forward to.
I have the manual that you provided the links for, it is a service manual and has been helpful in making adjustments. I was hoping that there was an owners manual that may provide the information about the mysterious non-existing button.
