SAFETY PRECAUTIONS IMPORT ANT SAFETY NOTICE Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by the Schematic Diagram and Replacement Parts List. It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent X-RADIATION, Shock, Fire, or other Hazards.
SERVICING PRECAUTIONS CAUTION: Before servicing receivers covered by this service transistors and semicounductor "chip" components. The manual and its supplements and addenda, read and follow the following techniques should be used to help reduce the SAFETY PRECAUTIONS on page 3 of this publication. incidence of component damage caused by static by static NOTE: If unforeseen circumstances create conflict between the electricity.
