Bingo. I've only had one problem with Yamaha: finding all the details in the manuals. Many subtle things are only explained in little notes after the main text of some category.
They also seem to want to save ink instead of make our lives easier: I've run across situations where I read the instructions on, say, Page 43, which refer me to Page 76 while I'm in the middle of doing the steps on Page 43. Writing a manual this way is irritating and unnecessary.
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
