CIRCUIT DIAGRAM

All manuals and user guides at all-guides.com

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These characteristics are

often passed unnoticed by a visual inspection and the protection afforded by them cannot necessarily be obtained by using

replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety charac-

teristics are identified in this manual and its supplements; electrical components having such features are identified by the

international hazard symbols on the schematic diagram and the parts list.

Before replacing any of these components, read the parts list in this manual carefully. The use of substitute replacement

parts which do not have the same safety character istics as specified in the parts list may create shock, fire, or other hazards.

PRODUCT SAFETY NOTICE
