When replaced of the U-PRO (Microprocessor) or the Flash ROM, confirm contents of the following.
PCB Name Ref. No. Description After replaced Remark
8U-210120-1 U1001 R5F100MFAFA A
After replacing
A : Mask ROM (With software). No need write-in of software to the microprocessor.
B : Flash ROM (With software). Usually, no need write-in of software. But, when the software was updated, you should
be write-in of the new software to the microprocessor or flash ROM. Please check the software version.
C : Empty Flash ROM (Without software). You should be write-in of the software to the microprocessor or flash ROM.
Refer to "Update procedure" or "writing procedure", when you should be write-in the software.

Adjustment Procedure
Set the power voltage to rated voltage for this adjustment.
DC offset Voltage Adjustment
1. Before turning on the power,
Insert Digital Voltage Meter between the SPEAKER SYSTEMS A (L CH) "+" and "–".
Insert Digital Voltage Meter between the SPEAKER SYSTEMS A (R CH) "+" and "–".
2. Turn on the power, VoLUMe is set as -∞ .
3. Press the SPeAKeR A button.
4. After turn on the power and 2 minutes pass, first L CH is adjusted.
The variable resistor V6002 on 8U-110131-1 is turned with adjustment driver, and the Digital Voltage Meter is adjusted
to " 0 mV ± 10 mV ".
5. Then, R CH is adjusted.
The variable resistor V7002 on 8U-110131-2 is turned with adjustment driver, and the Digital Voltage Meter is adjusted
to " 0 mV ± 10 mV ".
6. Although after-adjustment DC offset voltage has some change, Please check that the range of DC offset voltage
between L ch (R ch) "+" and L ch (R ch) "-" terminal of SPEAKER SYSTEMS A is " 0 mV ± 20 mV ".
