I. Safety Instructions
CAUTION: TO REDUCE THE RISK OF E ECTRIC
SHOCK, DO NOT REMOVE COVER (OR BACK). NO
USER-SERVICEAB E PARTSINSIDE. REFER
SERVICING TO QUA IFIED SERVICE PERSONNE
ON Y.
The lig htning flash w ith arro w head sym bol,
A within an equilateral triangle, is intended to alert
the user to the presence of uninsulated "dangerous
voltage within the product’ s enclosure that may
1 be of sufficient m agnitude to constitute a risk of
electric shock to persons.
A The exclam ation point w ith in an eq uila tera l
triang le is intended to a le rt the use r to the
presence of important operating and maintenance
. (s e rv ic in g ) in s tru c tio n s in the lite ra tu re
accom panying the appliance.
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 W iring. Note especially:
1) W ires 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 o f wires securely about
the terminals before soldering.
Make sure that wires do not contact heat generating
parts (heat sinks, oxide metal film resistors, fusible
resistors, etc.)
Check if replaced wires do not contact sharply edged
or pointed parts.
Make sure that foreign objects (screws, solder
droplets, etc.) do not remain inside the set.
SAFETY INSTRUCTION
The service should not be attempted by anyone
unfam iliar with the necessary instructions on this TV
receiver. The follow ing are the necessary instructions
to be observed before servicing.
1. An isolation transformer should be connected in the
power li ne between the receiver and the AC line
when a service is performed on the primary of the
converter transform er 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.
MAKE YOUR CONTRIBUTION TO PROTECT THE
ENVIRONMENT
Used batteries with the ISO symbol
for recycling as well as small
accumulators (rechargeable batteries), m ini-batteries
(cells) and starter batteries should not be thrown
into the garbage can.
Please leave them at an appropriate depot.

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.
5. When replacing a MAIN PCB in the cabinet, always
be certain that all protective are installed properly
such as control knobs, adjustm ent covers or shields,
barriers, isolation resistor networks etc.
6. When servicing is required, observe the original lead
dressing. Extra precaution should be given to assure
correct lead dressing in the high voltage area.
7. Keep wires away from high voltage or high tempera
ture components.
8. Before returning the set to the customer, always
perform an AC leakage current check on the exposed
m etallic parts of the cabinet, such as antennas,
terminals, screwheads, metal overlay, control shafts,
etc., to be sure the set is safe to operate without
danger of electrical shock. Plug the AC line cord
directly to the AC outlet (do not use a line isolation
transformer during this check). Use an AC voltmeter
having 5K ohms volt sensitivity or more in the
following manner.
Connect a 1.5K ohm 10 watt resistor paralleled by a
0.15|jF AC type capacitor, between a good earth
ground (water pipe, conductor etc.,) and the exposed
metallic parts, one at a time.
Measure the AC voltage across the combination of
the 1.5K ohm resistor and 0.15 uF capacitor. Reverse
the AC plug at the AC outlet and repeat the AC
voltage m easurements for each exposed metallic
part.
The measured voltage must not exceed 0.3V RMS.
This corresponds to 0.5mA AC. Any value exceeding
this lim it constitutes a potential shock hazard and
must be corrected immediately.
The resistance measurement should be done
between accessible exposed metal parts and power
cord plug prongs with the power switch "ON". The
resistance should be more than 6M ohms.
PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this TV
receiver have special safety-related characteristics.
These characteristics are offer passed unnoticed by
visual spection and the protection afforded by them
cannot necessarily be obtained by using replacement
com ponents rates for a higher voltage, wattage, etc.
The replacem ent parts which have these special
safety characteristics are identified b y ^ marks on
the schematic diagram and on the parts list.
Before replacing any of these components, read the
parts list in this manual carefully. The use of
substitute replacem ent parts which do not have the
same safety characteristics as specified in the parts
list may create shock, fire, X-RAY RADIATION or
other hazards.
