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.

CAUTION Please heed the points listed below during servicing and inspection.

Heed the cautions! Inspect for safety after servicing!

WIRE ARRANGEMENT
If wire bundles are untied or moved to perform adjustment or
parts replacement etc., be sure to rearrange them neatly as
they were originally bundled or placed afterward.
Otherwise, incorrect arrangement can be a cause of noise
generation.
