18. MICROPROCESSOR INFORMATION
The version, checksum and the port specified by the microprocessor are displayed. The signal is processed using
EFFECT OFF. The checksum is obtained by adding the data at every 16 bits for each program area and expressing the
result as a 4-figure hexadecimal data.

AMP ADJUSTMENT
Confirmation of Idling Current of Main (1) P. C. B.
• Right after power is turned on, confirm that the voltage
across the terminals of R64 (Main Lch), R65 (Main
Rch), R61 (Center), R59 (Rear Lch), R60 (Rear Rch),
R126 (Rear Cch) are between 0.1mV and 10.0mV.
• If it exceeds 10.0mV, open (cutoff) R39 (Main Lch), R40
(Main Rch), R37 (Center), R34 (Rear Lch), R35 (Rear
Rch), R117 (Rear Cch) and reconfirm the voltage.
• Confirm that the voltage is 0.20mV ~ 15.0mV after 60
minutes.
