Many electrical and mechanical parts in this chassis have special safety-related characteristics. These
parts are identified by       in the Schematic Diagram and EXPLODED VIEW. 
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. 
Do not modify the original design without permission of manufacturer.
