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

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.
