The web site can be searched: type a search term (e.g. "DAC10") into the search box on the right hand side of the header, and hit enter. the search engine will find words matching the search string in the main body of the site, but it won't search attached documents (e.g. the product manuals).
Many articles are displayed one after the other. some are quite short, and say "read more" at the bottom. Click that to read the remainder of the article.
