The customer service folks from Helm called me back (before the 5 day limit :-) and were as helpful as they could be. The good news is they are refunding my money as they realize they didn't send what was advertised. Better news - I don't need to return the manual, so I have a partially useful manual for free. They are going to call me back in a few more days to let me know if they really have the right F6B manual.

By the way, with reference to the previous post - this manual is excellent quality - definitely an original print and not a photocopy. All of the text, diagrams and photos are top quality. Price for the manual was $79.95 plus $10 shipping.
