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.

WIRE ARRANGEMENT ワイヤー整形図

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
