NOTICE WARNING:
ALL RESISTANCE VALUES IN OHM. k=1,000 OHM M=1,000,000 OHM Parts marked with this symbol have critical characteristics.
ALL CAPACITANCE VALUES IN MICRO FARAD. P=MICRO-MICRO FARAD Use ONLY replacement parts recommended by the manufacture.
EACH VOLTAGE AND CURRENT ARE MEASUERD AT NO SIGNAL INPUT
CAUTION:
CONDITION.
Before returning the unit to the customer, make sure you make either (1) a
CIRCUIT AND PARTS ARE SUBJECT TO CHANGE WITHOUT PRIOR
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 card 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.
