NOTICE WARNING:
ALL RESISTANCE VALUES IN OHM. k=1,000 OHM M=1,000,000 OHM Parts marked with this symbol
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
NOTICE. 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.
