2.PRODUCT 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 replacement component which
dose 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 information,
always
consult the current
PIONEER Service Manual.
A subscription to, or ad-
ditional copies of, PIONEER Service Manual may be
obtained at a nominal charge from PIONEER.
