This is a awesome quality scan of the original Service Manual for Technics 8099.
Contains the circuit diagram, PCB layout, adjust/tune instructions as well.
Since this is my first buy here, i'm really glad! This site do works as intended/described, it's definitely not scam!
Мои рекомендации! Все мануалы настоящие!
Very nice and real Service Manual, I didn't thought it actually exist in the real world at all.

How to Replace the Lithium Battery
Replacement Procedure
1. Remove the Main PCB (Refer to Disassembly Procedures.) 2. Remove the Lithium battery (Ref. No. �B9101� at foil side of Main PCB) and then replace it into new one.
NOTE: This Lithium battery is a critical component. (Type No.: ML-614S/F9FE Manufactured by Matsushita Battery Industrial Co.,Ltd.) It must never be subjected to excessive heat or discharge. It must therefore only be fitted in requirement designed specifically for its use. Replacement batteries must be of 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.
