Idling Current Adjustment
1. Adjust the Idling Current with the variable resistor R623
and R723 on the PCB (P601/P701).
2. Turn off the power.
3. "-" of Connect Digital Voltage is connected to the No. 1
pin and connected "+" to No. 3 pin of J609.
4. "-" of Connect Digital Voltage is connected to the No. 1
pin and connected "+" to No. 3 pin of J709.
5. Before turning on the power, R623 and R723 have been
counter clockwise turned with the adjustment driver.
6. Turn on the power, VOLUME is set as -
.
7. With seeing the digital voltage meter turn the variable
resister clockwise slowly to adjust the idling current.

Idling adjustment with R623 (R723).
• Turn R623 (R723) clockwise to increase the idling cur-
rent.
• The adjustment value of idling current is
10mV(50mA) ±0.5mV(2.5mA) each.
8. After 4 minutes, repeat the same procedure as 7.
• Turn R623 (R723) clockwise to increase the idling
current.
• The adjustment value of idling current is
10mV(50mA) ±0.5mV(2.5mA) each.
Adjustment is completed.
9. Remove connection cable, attach the top cover.
