wattage, etc. Replacement par ts which have these
special safety character istics are identified in this
Service Manual.
Electr ical components having such features are
identified by marking with a

on the parts list in this Service Manual.
The use of a substitute replacement component which
does not have the same safety characteristics as the
PIONEER recommended replacement one, shown in the
parts list in this Service Manual, may create shock, fire,
or other hazards.
Product Safety is continuously under review and new
instructions are issued from time to time. For the latest
infor mation, always consult the current PIONEER
