Page 6: Important Safety Precautions
IMPORTANT SAFETY PRECAUTIONS Prior to shipment from the factory, our products are strictly inspected for recognized product safety and electrical codes of the countries in which they are to be sold. However, in order to maintain such compliance, it is equally important to implement the following precautions when a set is being serviced.
Page 7 ing is performed that involves B+, horizontal de- earth ground. If a voltage reading in excess of 1.0V flection or high voltage. Correct operation of the is obtained, remove and reinsert the AC power X-radiation protection circuits also must be recon- plug in the opposite polarity and again measure firmed each time they are serviced.
Page 8 Precautions during Servicing H. When a power cord has been replaced, check that 5~6 kg of force in any direction will not loosen it. A. Parts identified by the ( # ) symbol are critical for I. Also check areas surrounding repaired locations. safety.
Page 9 Safety Check after Servicing Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, Chassis or Secondary Conductor parts and wires have been returned to original posi- tions. Afterwards, perform the following tests and con- Primary Circuit Terminals firm the specified values in order to verify compliance with safety standards.
