SAFETY PRECAUTION
Many
electrical
and
mechanical
parts
in
this
chassis
have
special
safety-related
characteristics.
These
characteristics
are
often
passed
unnoticed
by
a
visual
inspection
and
the
protection
afforded
by
them
cannot
necessarily
be
obtained
by
using
replacement
components
rated
for
higher
voltage,
wattage,
etc.
Replacement
parts
which
have
these
special
safety
characteristics
are
identified
in
this
manual,
electrical
components
having
such
features
are
identified
by
a
/\
in
the
schematic
diagram
and
the
parts
list.
Before
replacing
any
of
these
components,
read
the
parts
list
in
this
manual
carefully.
The
use
of
substitute
replacement
parts
which
do
not
have
the
same
safety
characteristics
as
specified
in
the
parts
list
may
create
shock,
fire
or
other
hazards.
