EXPLODED VIEW
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.
IMPORTANT SAFETY NOTICE
THE    SYMBOL MARK OF THIS SCHEMETIC DIAGRAM INCORPORATES
SPECIAL FEATURES IMPORTANT FOR PROTECTION FROM X-RADIATION.
FILRE AND ELECTRICAL SHOCK HAZARDS, WHEN SERVICING IF IS 
ESSENTIAL THAT ONLY MANUFATURES SPECFIED PARTS BE USED FOR
THE CRITICAL COMPONENTS IN THE    SYMBOL MARK OF THE SCHEMETIC.
