2.PRODUCT SAFETY NOTICE
Many
electrical
and
mechanical
parts
in
the
appliance
have
special
safety
related
characteristics.
These
are
often
not
evident
from
visual
inspection
nor
the
protection
afforded
by
them
necessarily
can
be
obtained
by
using
replacement
components
rated
for
voltage,
wattage,
etc.
Replacement
parts
which
have
these
special
safety
charac-
teristics
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 additional copies of, PIONEER
