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. 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. 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.

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
(OR BACK). NO USER-SERVICEABLE PARTS
INSIDE. REFER SERVICING TO QUALIFIED
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.
