Here are a few shots from Wersi manuals, there are many others but it should give you an idea of the general layout and operation. (They say a picture paints a thousand words)
I have also included the number of pages in the manuals. (Each manual is only ever in 1 language)
http://www.4shared.com/file/34643925/57dbe634/User.html 148 pages
http://www.4shared.com/file/34643983/4457ab8b/Program.html 140 pages
http://www.4shared.com/file/34644028/bb6c99bf/OAA.html 60 pages

Enjoy
