Dear friends,
My AV-900 needs to be calbirated as the volume it shows is really off. However I don't have access to the service manual and don't know which potentiometer can calibrate the volume and zero motor position.
I would like to know if anyone can give me a step by step procedure or anything helpful. Surely I would appreciate if anyone could at least share this part of the service manual.
Best regards,
Dr. Esmaeili
