Apparently the Mk II manual is much larger.

Post directly above yours, Robert...

Yeah, I saw your post and wasn't deliberately ignoring it. I responded to HPL because he said it first and because I wanted to comment on his point about the brevity of the printed manual.

I came across this almost 3 years later because I had an "!" on my 7Dii screen for the first time.  Thanks for the help.  I'll just add that mine was warning me that I had Picture Style set to Monochrome.  I had it on that for lens microadjustment testing and didn't  want it there after the testing was done.

Guys, guys!  What difference does it make how many pages are there in the manual.  I still haven't seen the resolution to Exclamation Mark.  I know it is a Warning of some sort, warning me about some setting that I may have chosen unintentionally.  I got that from David Busch's boonk on EOS 7D M2.  But there were no specifics or I haven't reached that page number yet.  Guess, I'll have to do little more research. 

Thank you all very much.
