Hi-Fi Component SERVICE MANUAL MODEL AVR-3801 AV SURROUND RECEIVER Some illustrations using in this service manual are slightly different from the actual set. AVR-3801 SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective. SPECIFICATIONS !
