NOTE FOR SCHEMATIC DIAGRAM

WARNING:Parts marked with this symbol ! have critical characteristics.Use ONLY replacement parts recommended by the manufactur-er.

CAUTION:Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resis-tance 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.

WARNING:DO NOT return the unit to the customer until the problem is lo-cated and corrected.

NOTICE:ALL RESISTANCE VALUES IN OHM. k=1,000 OHMM=1,000,000 OHMALL CAPACITANCE VALUES IN MICRO FARAD.P=MICRO-MICRO FARADEACH VOLTAGE AND CURRENT ARE MEASURED ATNO SIGNAL INPUT CONDITION.CIRCUIT AND PARTS ARE SUBJECT TO CHANGEWITHOUT PRIOR NOTICE.
