CONFIRMATION OF IDLING CURRENT
1. Right after the power is turned on, confirm that the volt-
age across the terminals of R137 (L ch) and R138 (R ch)
are between 0.1mV to 10.0mV.
2. If the measured voltage exceeds 10.0mV, open (cut off)
R131 (L ch), R132 (R ch) and reconfirm the voltage.
3. Confirm that the voltage is between 0.20mV and 15.0mV
after 60 minutes.
