SAFETY INSTRUCTIONS
SAFETY CHECK AFTER SERVICING
Confirm the specified insulation resistance between power cord plug prongs and externally exposed parts of the set is
greater than 10 Mohms, but for equipment with external antenna terminals (tuner, receiver, etc.) and is intended for
or [A], specified insulation resistance should be more than 2.2 Mohms (ground terminals, microphone jacks,
headphone jacks. line-in-out jacks etc.)
PRECAUTIONS DURING SERVICING
1.
Se eND
Parts identified by the A\ symbol parts are critical for safety.
Replace only with parts number specified.
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.
Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
Use specified insulating materials for hazardous live parts. Note especially:
1) Insulation Tape
2) PVC tubing
3) Spacers (Insulating Barriers)
4) Insulation sheets for transistors
5) Plastic screws for fixing microswitch (especially in turntable)
When
replacing
AC
primary
side
components
(transformers,
power
cords,
noise
blocking
capacitors,
etc.),
wrap
ends
of wires
securely
about
the terminals before
soldering.
c> c>
Observe
that
wires
do
not
contact
heat
producing
parts
(heatsinks,
oxide
metal
film
resistors,
fusible
resistors,
etc.).
.
Check
that
replaced wires
do
not
contact
sharp
edged
or pointed parts.
Also
check
areas
surrounding
repaired
locations.
Use
care
that
foreign
objects
(screws,
solder
droplets,
etc.)
do
not
remain
inside
the set.
Voltage
Conversion
and
Best
Selector
1)
Voltage Conversion
Models
for
Japan,
Canada,
USA,
Europe,
UK
and
Australia
are
not
equipped
with
this
facility.
Each
machine
is
preset
at
the
factory
according
to
destination,
but
some
machines
can
be
set
to
110V—120V
or
220—240V
as
required.
If
your
machine’s
voltage
can
be
converted:
1-1) Disconnect
the
power
cord.
1-2)
Remove
the
cover plate.
1-3) Move the
Voltage
Selector
located
on
the
rear panel
with
a
screwdriver.
So
that the
marker is below the
voltage
for your area.
(Refer
to
Fig.
1)
2) Cycle
Conversion
With
DC
motor cycle
conversion
is
not
necessary.
