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.
