parts
are
critical
for
‘safety.
Replace
only

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
replacements.
Examples:
RF
converters,
tuner
units,
antenna
selector
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
leads
4.
Use
specified
insulating
materials
for
hazardous
live
parts.
Note.
especially:
1)
Insulation
Tape
2)

film
resistors,
fusible
resistors,
etc.).

INFORMATION
7.
Check
that
replaced
wires
do
not
contact
sharp
edged
or
pointed
parts.
8.
Also

care
that
foreign
objects
(screws,
solder
droplets,
etc.)
do
not
remain
inside
the
set.
SAFETY
CHECK
AFTER
SERVICING
Confirm

prongs
and
externally
exposed
parts
of
the
set
is
greater
than
