SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
LEAKAGE CURRENT CHECK
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.
