WARNING
Lead in solder used in this product is listed by the California Health and Welfare agency as
a known reproductive toxicant which may cause birth defects or other reproductive harm
(California Health & Safety Code, Section 25249.5).
When servicing or handling circuit boards and other components which contain lead in
solder, avoid unprotected skin contact with the solder. Also, when soldering do not inhale

SAFETY
NOTICE
Many electrical and mechanical parts in the appli-
ance have special safety related characteristics. These
are often not evident from visual inspection nor the
protection afforded by them necessarily can be ob-
tained by using replacement components rated for vol-
tage, wattage,
etc. Replacement
parts which have
these special safety characteristics are identified in
this Service Manual.
Electrical components
having such features
are
identified by marking with.a A on the schematics and
on the parts list in this Service Manual.
The use of a substitute replacernent component which
dose not have the same safety characteristics as the
PIONEER recommended replacement one, shown in
the parts list in this Service Manua!, 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 information, always consw't the current
PIONEER Service Manual.
A subscription to, or ad-
ditional copies of, PIONEER Service Manual may be
