AV SURROUND RECEIVER SR9300
Updated of the CPU and DSP DISC ...........................*SR9300CDR
The disc is used when QU01 and Q671 are replaced.
No software is in the IC's when replaced.
Refer the service manual for SR9200/SR8200/PS9200 (344J855010) to upload software.
The procedure to upload is the same to the SR9200/SR8200/PS9200.
However the software is NOT the same to the SR9200/SR8200/PS9200.
NEVER write the software to SR9200/SR8200/PS9200. It causes breakdown.
So be careful to use this disc to upload.
