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"!

3.3. INSERTING THE BUTTON-TYPE BATTERY
Note:
The lithium battery is a critical component (Type No.: CR2025 Manufactured by Panasonic.) It must never be subjected to excessive heat or discharge. It must therefore only be fitted in equipment designed specifically for its use. Replacement batteries must be of the same type and manufacture. They must be fitted in the same manner and location as the original battery, with the correct polarity contacts observed. Do not attempt to re-charge the old battery or re-use it for any other purpose. It should be disposed of in waste products destined for burial rather than incineration.
