NOTE FOR SCHEMATIC DIAGRAM
WARNING:
Parts marked with this symbol z have critical characteristics. Use ONLY replacement parts recommended by the manufacture r.
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 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 located and corrected.
NOTICE:
ALL RESISTANCE VALUES IN OHM. k=1,000 OHM / M=1,000,000 OHM
ALL CAPACITANCE VALUES IN MICRO FARAD. P=MICRO-MICRO FARAD EACH VOLTAGE AND CURRENT ARE MEASURED AT NO SIGNAL
INPUT CONDITION. CIRCUIT AND PARTS ARE SUBJECT TO CHANGE WITHOUT PRIOR NOTICE.
Parts 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. (Refer to the Schematic Diagram for those parts.)
Parts marked with this symbol z have critical characteristics. Use ONLY replacement parts recommended by the manufacturer.
Not including General-purpose Carbon Film Resistor in the P.W.Board parts list. (Refer to the Schematic Diagram for those parts.)
