Once again owner-manual.com has saved the day for me, and come through with the manual I need. I looked other places too, and couldn't find it anywhere. Thank You owner-manual.com!!! You're the BEST!
The service manual is really great - thanks to it I was able to install the laser unit and thus "save" my CD-player, which seemed to be impossible before I had the manual.

Note: The lithium battery is a critical component. (Type No.: VSB0407 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.
