If the measured voltage exceeds1.6mV, cut the
lead wire of R557(L ch), R565(R ch), R572(C ch),
R744(RL ch) or R751(RR ch) and then check
again if each measured value satisfies the rating.
*
Confirm that the voltage at the test points is 7.5mV ~ 12mV after 60 minutes.

•
If R557(L ch), R565(R ch), R572(C ch), R744(RL ch) or R751(RR ch) have already been
cut off and idling current does not flow, reconnect R557(820
