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.
;
High quality scan of original Service Manual. Everything´s fine!

[3] Downloading Sequence
A
� Downloading the firmware to the AUDIO DSP
Downloading the firmware to the AUDIO DSP is performed in 4 sessions. 1. After reset of the AUDIO DSP is canceled, DSPCS# is set to �L.� Then transfer of the initialization program 1 starts. 2. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �L.� 3. DSPCS# is set to �L.� Then transfer of the initialization program 2 starts. 4. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �H.� 5. DSPCS# is set to �L� then transfer of the initial values starts. 6. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �L.� 7. DSPCS# is set to �L.� Then transfer of the program for the main unit starts. 8. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �H.� Downloading is completed. DSPCS# (Pin 50)
B
SPICLK (Pin 53) SPIOUT (Pin 55) DSPDREQB# (Pin 27) Approx. 110 msec Note: The above-mentioned pin numbers are those of the IC202 (SOUTH CPU). Transfer of the initialization program 1 Transfer of the initialization program 2 Transfer of the initial values Transfer of the program for the main unit
C
� Downloading the firmware to the FPGA
1. The FPGRM is set to �H.� 2. It is checked that SD2_OUT is set to �H.� 3. Transfer of the FPGA firmware starts. 4. After the transfer is completed, it is checked that DONE is set to �H.� 5. After a wait of 1 ms or more, FPGARST# is set to �H� (released). Downloading is completed. FPRGM (Pin 38) SD2_OUT (Pin 36) SPICLK (Pin 53)
D
SPIOUT (Pin 55) FDONE (Pin 37) FPGARST# (Pin 46)
Transfer of the FPGA firmware 1 ms or more
Approx. 200 msec Note: The above-mentioned pin numbers are those of the IC202 (SOUTH CPU).
