Idling
Pre-check
Channel
FL,FR,C,SL,SR,SBL,SBR
Terminals
P6021,P6022,P6023,P6025,P6026,P6027,P6028
*Connect 1/4W 100 ohms resisters in each probe of multi mater .
*Make sure from 1mV to 21mV, When it is not this range, you have to make sure again repair.
b.
Aging
The AVR is turned on about 6 minutes for aging.
c.
Idling After-check
*Equip series 1/4W 100-ohm resisters near the terminal respectively in each pole of the jig used for the above mentioned terminals.
*If the measured value are under 1 mV or over 21 mV, turn off the power of the AVR and rework the AVR.
*Connect 1/4W 100 ohms resisters in each probe of multi mater .
*Make sure from 1mV to 21mV, When it is not this range, you have to make sure again repair.
