WARNING:
x Parts marked with this symbol a o have critical characteristics.
y
Use ONLY replacement parts recommended by the manufacture.
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
i
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.
