This was an excellent source of detailed assembly information on a device which is at least 12 years old. A very lucky find, coupled with great service.
Excellent Service Manual and best price on the Internet. This Service Manual covers everything you could ever need including full circuit schematics, component layout diagrams, stripdown procedure and full parts list/breakdown. I needed this to carry out a modification to one of these headunits and this manual covered everything I needed. Fast delivery, processed within a few hours.
Thought I would never find a copy of the Technics SX-EN2 Service Manual until I found Owner-Manuals.com. Price was very fair and I received the download promptly. While a photocopy, it is quite readable and includes all the pertinent information and diagrams. Thank you Owner-Manuals!
I really like this manual and it's reliable.I found and bought easly.thank you.

5 HOW TO REPLACE THE LITHIUM BATTERY (PROCEDURE)
1. Remove the Top Flex. Unit. (Refer to Disassembly Procedures.) 2. Unsolder the Lithium Battery �VSB0407� and then replace the new one. (See Fig. B1.)
Fig. B1
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.
