Safety Precaution

PRECAUTIONS DURING

SERVICING

1. 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
selection switches, RF cables, noise-blocking
capacitors, noise-blocking filters, etc.

2. Use specified internal Wiring. Note especially:

1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads

3. Use specified insulating materials for hazardous

live parts. Note especially:
1) Insulating Tape
2) PVC tubing
3) Spacers (insulating barriers)
4) Insulating sheets for transistors
5) Plastic screws for fixing micro switches

4. When replacing AC primary side components

(transformers, power cords, noise blocking
capacitors, etc.), wrap ends of wires securely
about the terminals before soldering.

5. Make sure that wires do not contact heat

generating parts (heat sinks, oxide metal film
resistors, fusible resistors, etc.)

6. Check if replaced wires do not contact sharply

edged or pointed parts.

7. Make sure that foreign objects (screws, solder

droplets, etc.) do not remain inside the set.

The lightning flash with arrowhead symbol,

within an equilateral triangle, is intended to

alert the user to the presence of uninsulated

“dangerous voltage” within the product’s enclo

sure that may be of sufficient magnitude to

constitute a risk of electric shock to persons.

The exclamation point within an equilateral

triangle is intended to alert the user to the

presence of important operating and

maintenance (servicing) instructions in the

literature accompanying the appliance.

CAUTION: TO REDUCE THE RISK OF

ELECTRIC SHOCK, DO NOT REMOVE COVER

INSIDE. REFER SERVICING TO QUALIFIED

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

(OR BACK). NO USER-SERVICEABLE PARTS

SERVICE PERSONNEL ONLY.

MAKE YOUR CONTRIBUTION

TO PROTECT THE

ENVIRONMENT

Used batteries with the ISO symbol

for recycling as well as small accumulators
(rechargeable batteries), mini-batteries (cells) and
starter batteries should not be thrown into the
garbage can.

Please leave them at an appropriate depot.

WARNING:

Before servicing this TV receiver, read the
SAFETY INSTRUCTION and PRODUCT
SAFETY NOTICE.

SAFETY INSTRUCTION

The service should not be attempted by anyone

unfamiliar with the necessary instructions on this
apparatus. The following are the necessary
instructions to be observed before servicing.
1. An isolation transformer should be connected in

the power line between the receiver and the
AC line when a service is performed on the
primary of the converter transformer of the set.

2. Comply with all caution and safety related

provided on the back of the cabinet, inside the
cabinet, on the chassis or picture tube.

3. To avoid a shock hazard, always discharge the

picture tube's anode to the chassis ground
before removing the anode cap.

4. Completely discharge the high potential voltage

of the picture tube before handling. The picture
tube is a vacuum and if broken, the glass will
explode.
