2、one: 03 (3584) 8111 X0117 1174 NC 0109 RadioFans.CN 2 AVR-1802/882 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

3、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 ? ? ? ? ?
