SAFETY
NOTICE
Many
electrical

in
the

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

having
such
features
are
identified
by
marking
witha
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.
