This document is just what I was looking for, it´s very useful, it contains adjustment procedures for the final stage of the power amp and also
has a complete wiring diagram and description of the main semiconductors used in the design.

Dear Sirs,
Thank you for the fast support, the manual does provide all necessary information to repair the radio. All schematics are in a good quality for reading.
The manual fits 100% to my requirements as a technican.
Kind regards Thomas

the big video recorder format s-vhs many features delicate in loading system of the cassette. Such machines are no longer manufactured, it would be too expensive.
 ;
THIS MANUAL IS VERY GOOD AND VERY CLEAR
PLEASE NOTE IT DOES NOT CONTAIN THE SETUP INFORMATION TO ALIGHN THE GEARS IN THE CD MECH IT DOES SHOW ALL THE PARTS AND THEIR LOCATIONS .
;
Complete service and operation manual. All schematics are there, all circuit boards AND add-on boards. Including exploded views ,component names and specifications. Also electrical and mechanical adjustment procedures are in this manual. This manual also covers the more advanced BR-S811E unit. Scan quality is fair and usable.
ADJUSTMENT

Procedure 1. Connect the Choronometer to TP218. 2. Connect the B/U and ACC line, and Turn on the ACC switch. 3. LCD display change Ver.---, While holding the buttons of MENU,M1,M5 and POWER. 4. Adjust TC201 so that an output of TP218 becomes 0.0 +0.2/-0.0Sec./day. 1. Input the 98.1MHz/55dBu(1kHz 22.5kHz Div.) SSG signal. 2. Set the output to 0dBm(1V)by main volume. 3. Adjust VR102 so that the output level is -18+3/-3dB down when the output of SSG is set to -20dBu. Connect the SSG to Main antenna (Red) side. Set the minimum VR101. Input the 98.1MHz/1kHz 22.5kHz(30%) Div. SSG signal. Input the 26dBu SSG signal and adjust VR101 so that an output of TP101(DIVADJ) becomes High from Low. 5. Confirm that TP101(DIV-ADJ) becomes Low from High within about three seconds of input the 22dBu SSG signal. 6. Confirm that TP101(DIV-ADJ) becomes 10.0V from 2.0V within about one second of input the 30dBu SSG signal. 7. Confirm that TP101(DIV-ADJ) is as follows 1.0V within five seconds of input the 20dBu SSG signal.
