The manual is complete with excellent quality! One suggestion, show number of pages and weather it is multi-lingual. The AD 600 Manuel is about 76 pages and over half is non English. This results in a larger print job than usually needed. Having this information, one could select the desired pages for printing.
Very happy to find this from owners-manual.com and the enclosed spec sheet as well.
