SAFETY
PRECAUTION
(This
“safety
precaution”
is
applied
only
in
U.S.A))
.
Before
servicing,
unplug
the
power
cord
to
prevent
an
electric
shock.
.
When
replacing
parts,
use
only
manufacturer’s
recommended
components
for
safety.
.
Check
the
condition
of
the
power
cord.
Replace
if
wear
or
damage
is
evident.
.
After
servicing,
be
sure
to
restore
the
lead
dress,
insulation
barriers,
insulation
papers,
shields,
etc.
.
Before
returning
the
serviced
equipment
to
the
customer,
be
sure
to
make
the
following
insulation
resistance
test
to
prevent
the
customer
from
being
exposed
to
a
shock
hazard.

1.
Unplug
the
power
cord
and
short
the
two
prongs
of
the
plug
with
a
jumper
wire.
2.
Turn
on
the
power
switch.
3.
Measure
the
resistance
value
with
ohmmeter
between
the
jumpered
AC
plug
and
each
exposed
metal
cabinet
part,
such
as
screwheads
antenna,
control
shafts,
handle
brackets,
etc.
Equipment
with
antenna
terminals
should
read
between

and
5.2M{2

all
exposed
parts.
(Fig.

Equipment
without
antenna
terminals
should
read
approximately
infinity

all
exposed
parts.

Note:
Some
exposed
parts
may
be
isolated
from
the
chassis
by
design.
These
will
read
infinity.

If
the
measurement
is
outside
the
specified
limits,
there
is
a
possibility
of
a

hazard.
The
equipment
should
be
repaired
and
rechecked
before
it
is
returned
to
the
customer,
