WARNING:
Parts marked with this symbol have critical characteristics.
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
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.
