INSTRUCTIONS
PRECAUTIONS
DURING
SERVICING
1.
Parts
indentified
by
the
“\
()
symbol
are
critical
for
safety.
Replace
only
with
parts
number
specified.
2.
In
addition
to
safety,
other
parts
and
assemblies
are
specified
for
conformance
with
such
regulations
as
those
applying
to
spurious
radiation.
These
must
also
be
replaced
only
with
specified
re-
placements.
Examples:
RF
converters,
tuner
units,
antenna
selec-
tor
switches,
RF
cables,
noise
blocking
capacitors,
noise
blocking
filters,
etc.
3.
Use
specified
internal
wiring.
Note
especially:
1)
Wires
covered
with
PVC
tubing
2)
Double
insulated
wires
3)
High
voltage

4.
Use
specified
insulating
materials
for
hazardous
live

Note
especially:
1)
Insulation

SERVICE
MANUAL
SAFETY
CHECK
AFTER
SERVICING
After
servicing,
make
measurements
of
leakage-current
or
resistance
in
order
to
determine
that
exposed
parts
are
acceptably
insulated
from
the
supply
circuit.
The
leakage-current
measurement
should
be
done
be-
tween
accessible
metal
parts
(such
as
chassis,
ground
terminal,
microphone
jacks,
signal
input
/
output
connec-
tors,
etc.)
and
the
earth
ground
through
a
resister
of
1500
ohms
paralleled
with
a
0.15
uF
capacitor,
under
the
unit's
normal
working
conditions.
The
leakage-current
should
be
less
than
0.5
mA
rms
AC.
The
resistance
measurement
should
be
done
between
accessible
exposed
metalparts
and
power
cord
plug
prongs
with
the
power
switch
(if
included)
“ON”.
The
resistance
should
be
more
than
2.2
Mohms.

pleae
note
the
follow-
ing
points.
1.
Do
not
put
excessiv
pressure
on
the
mechanical
part
(operation
part),
including
the
pick-up
block,
as
ex-
tremely
high
mechanical
precision
is
required
in
these
parts.
2.When
the
base
is
removed
for
repair
or
adjustment,
make
sure
that
there
are
no
metal
obiects
in
the
nar-
row
gap
between
the
P.C.board
or
the
mecha
parts
and
the
base.
3.
The
Micro-Computer
and
the
CD
signal
processing
!Cs
can
be
damaged
by
static
electricity
or
leakage
from
a
soldering
iron
during
repairing.
While
soldering,
please
take
the
precautions
against
leakage
as
in
