I downloaded the manual from the website in PDF form, and put it in iBooks on my iPad so that I could read it like a book.
That's what I did, on my iPad Pro the pages are almost 8 1/2 x 11 so are quite legible.
Virtual material is harder to browse, and, unless it has a good indexing system, harder to look up.
Index works well, all page numbers are clickable making it easy to jump to the content you're looking for. Additionally, since the PDF is text (as opposed to pictures of text) you can search using any arbitrary word.
