The
design
this
product
contains
special
hardware and
many
circuits
and
components
specially
for
safety
purposes
.
For
continued
protection
,
no
changes
should be made
to
the
original design
unless authorized
in
writing by
the
manufacturer
.
Replacement
parts
must
be identical
to
those
used
in
the
original
circuits
.
Service
should be
performed
by
qualified
personnel
only
.

Alterations
of
the
design
or
circuitry
of
the
product
should
not
be
made
.
Any
design
alterations
of
the
product
should
not
be
made
.
Any design
alterations
or
additions
will
void the

.
Many
electrical and
mechanical
parts
in
the
product
have
special
safety
—
related
characteristics
.
These
characteristics
are
often
not
evident
from
visual
inspection
nor can
the
protection
afforded
by
them
necessarily
be obtained
by using
replacement
components
rated
for
higher
voltage
,
wattage
,
etc
.
Replacement
parts
which have these
special
safety
characteristics
are
identified
in
the
parts
list
of
service manual
.
Electrical
components
having
such
features
are
identified
by
shading
and
(
A
\
)
on
the
schematic
diagram
and
by
( )
on
the
parts
list
in
the
service manual
.
The
use
of
a
substitute
replacement
which
does
not
have the
same
safety
characteristics
as
the
recommended
replacement
part
shown
in
the
parts
list
of
service
manual
may
create
shock
,
fire
,
or
other hazards
.
4
.
The
leads
in
the
products
are
routed and dressed
with
ties
,
clamps
,
tubings
,
barriers
and the like
to
be
separated
from
live
parts
,
high
temperature
parts
,
moving
parts
and
or
sharp
edges
for
the
prevention
of
electric shock and
fire
hazard
.
When service
is
required
,
the
original
lead
routing
and dress
should
be observed
,
and
it
should be
confirmed
that
they
have been
returned
to
normal
,
after
reassembling
.

.
Leakage
current
check
(
Electrical
shock
hazard
testing
)
After
re
—
assembling
the
product
,
always
perform
an
isolation check
on
the
exposed
metal
parts
of
the
product
(
antenna
terminals
,
knobs
,
metal cabinet
,
screw
heads
,
headphone
jack
,
control
shafts
,
etc
.
)
to
be
sure
the
product
is
safe
to
operate
without
danger
of
electrical
shock
.
Do
not
use a
line isolation
transformer
during
this check
.
•
Plug
the
AC
line
cord
directly
into the
AC
outlet
,
using

,
measure
the
