Could a manual be more poorly written?

I doubt it! The Bernina 830 manual is confusing, not helpful, and cryptic. For example this evening I am attempting to use the dual feed feature of the machine. There is no reference to dual feed in the index. The help built into the machine is useless. I attached the 4d presser foot and tried to sew. Big red X. Nothing in the manual references this. I am now paging through the manual and making my own index. The sad thing about this is remembering asking the Bernina representative about the manual and she raved about the abundance of documentation. What a fool I was.
