A comprehensive Operating and Service Manual. All schematics are complete and easy to read. The PCB drawings and complete parts list are very helpful. I would definitely recommend this manual.
Genuine Toshiba owner's manual. Couldn't really ask for more. And written in understandable English in contrast to a few recent experiences I have had with manuals for other equipment other than Toshiba but made in China and written in "Chinglish"!
