3NOTE FOR SCHEMATIC DIAGRAMWARNING:Parts marked with this symbol z have critical characteristics. Use ONLY replacement parts recommended by the manufacturer.CAUTION: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 theleakage 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 located and corrected.NOTICE:ALL RESISTANCE VALUES IN OHM. k=1,000 OHM / M=1,000,000 OHMALL CAPACITANCE VALUES IN MICRO FARAD. P=MICRO-MICRO FARAD EACH VOLTAGE AND CURRENT ARE MEASURED AT NO SIGNALINPUT CONDITION. CIRCUIT AND PARTS ARE SUBJECT TO CHANGE WITHOUT PRIOR NOTICE.NOTE FOR PARTS LISTParts for which "nsp" is indicated on this table cannot be supplied.When ordering of part, clearly indicate "1" and "I" (i) to avoid mis-supplying.Ordering part without stating its part number can not be supplied.Not including General-purpose Carbon Chip Resistor in the P.W.Board parts list.
