SERVICING NOTICES ON CHECKING
6. AVOID AN X-RAY1. KEEP THE NOTICES
As for the places which need special attentions,
they are indicated with the labels or seals on the
cabinet, chassis and parts. Make sure to keep the
indications and notices in the operation manual.
3. USE THE DESIGNATED PARTS
5. TAKE CARE TO DEAL WITH THE
CATHODE-RAY TUBE
In the condition that an explosion-proof cathode-
ray tube is set in this equipment, safety is
secured against implosion. However, when
removing it or serving from backward, it is
dangerous to give a shock. Take enough care to
deal with it.
Safety is secured against an X-ray by consider-
ing about the cathode-ray tube and the high
voltage peripheral circuit, etc.
Therefore, when repairing the high voltage pe-
ripheral circuit, use the designated parts and
make sure not modify the circuit.
Repairing except indicates causes rising of high
voltage, and it emits an X-ray from the cathode-
ray tube.
Please include the following informations when you order parts. (Particularly the VERSION LETTER.)
1. MODEL NUMBER and VERSION LETTER
The MODEL NUMBER can be found on the back of each product and the VERSION LETTER can be

And be sure the safety of that.
(INSULATION CHECK PROCEDURE)
1.
2.
3.
4.
Unplug the plug from the AC outlet.
Remove the antenna terminal on TV and turn
on the TV.
Insulation resistance between the cord plug
terminals and the eternal exposure metal
[Note 2] should be more than 1M ohm by
using the 500V insulation resistance meter
[Note 1].
If the insulation resistance is less than 1M
ohm, the inspection repair should be
required.
[Note 1]
If you have not the 500V insulation
resistance meter, use a Tester.
[Note 2]
External exposure metal: Antenna terminal
Earphone jack
2. AVOID AN ELECTRIC SHOCK
There is a high voltage part inside. Avoid an
electric shock while the electric current is
flowing.
The parts in this equipment have the specific
characters of incombustibility and withstand
voltage for safety. Therefore, the part which is
replaced should be used the part which has
the same character.
Especially as to the important parts for safety
which is indicated in the circuit diagram or the
table of parts as a mark, the designated
parts must be used.
4. PUT PARTS AND WIRES IN THE
ORIGINAL POSITION AFTER
ASSEMBLING OR WIRING
There are parts which use the insulation
material such as a tube or tape for safety, or
which are assembled in the condition that
these do not contact with the printed board.
The inside wiring is designed not to get closer
to the pyrogenic parts and high voltage parts.
Therefore, put these parts in the original
positions.

READ INSTRUCTIONS
All the safety and operating instructions should be read before the unit is operated.
RETAIN INSTRUCTIONS
The safety and operating instructions should be retained for future reference.
HEED WARNINGS
All warnings on the unit and in the operating instructions should be adhered to.
FOLLOW INSTRUCTIONS
All operating and use instructions should be followed.
CLEANING
Unplug this unit from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.
ATTACHMENTS
Do not use attachments not recommended by the unit’s manufacturer as they may cause hazards.
WATER AND MOISTURE
Do not use this unit near water. For example, near a bathtub, washbowl, kitchen sink, or laundry tub, in a wet basement, or near a
swimming pool.
ACCESSORIES
Do not place this unit on an unstable cart, stand, tripod, bracket, or table. The unit may fall,
causing serious injury, and serious damage to the unit. Use only with a cart, stand, tripod,
bracket, or table recommended by the manufacturer.
An appliance and cart combination should be moved with care. Quick stops, excessive force,
and uneven surfaces may cause the appliance and cart combination to overturn.
VENTILATION
Slots and openings in the cabinet and in the back or bottom are provided for ventilation, to ensure reliable operation of the unit, and
to protect it from overheating. These openings must not be blocked or covered. The openings should never be blocked by placing
the unit on a bed, sofa, rug, or other similar surface. This unit should never be placed near or over a radiator or heat source. This
unit should not be placed in a built-in installation such as a bookcase or rack unless proper ventilation is provided or the manufac-
turer’s instructions have been adhered to.
POWER SOURCES
This unit should be operated only from the type of power source indicated on the rating plate. If you are not sure of the type of
power supply to your home, consult your appliance dealer or local power company. For units intended to operate from battery
power, or other sources, refer to the operating instructions.
GROUNDING OR POLARIZATION
This unit is equipped with a polarized alternating-current line plug (a plug having one blade wider than the other). This plug will fit
into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the
plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the
polarized plug. If your unit is equipped with a 3-wire grounding-type plug, a plug having a third (grounding) pin, this plug will only fit
into a grounding-type power outlet. This too, is a safety feature. If you are unable to insert the plug into the outlet, contact your
electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding-type plug.
POWER-CORD PROTECTION
Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them,
paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance.
LIGHTNING
To protect your unit from a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall
outlet and disconnect the antenna or cable system. This will prevent damage to the unit due to lightning and power line surges.
POWER LINES
An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or
where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to
keep from touching such power lines or circuits, as contact with them might be fatal.
OVERLOADING
Do not overload wall outlets and extension cords, as this can result in a risk of fire or electric shock.
OBJECT AND LIQUID ENTRY
