I. Safety Instructions
１／１００
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
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 enclosure that may
be of sufficient magnitude to constitute a risk of
electric shock to persons.
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.
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.
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.
The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operating and maintenance
(s erv ici ng) in str uct io ns in the li ter atu re
accompanying the appliance.
WARNING:
Before servicing this TV receiver, read the X-RAY
RADIATION PRECAUTION, SAFETY INSTRUCTION
and PRODUCT SAFETY NOTICE.
X-RAY RADIATION PRECAUTION
1. Excessively high can produce potentially hazardous
X-RAY RADIATION. To avoid such hazards, the high
voltage must not exceed the specified limit. The
normal value of the high voltage of this TV receiver
is 27 KV at zero bean current (minimum brightness).
The high voltage must not exceed 30 KV under any
circumstances. Each time when a receiver requires
servicing, the high voltage should be checked. The
reading of the high voltage is recommended to be
recorded as a part of the service record, It is
important to use an accurate and reliable high
voltage meter.
2. The only source of X-RAY RADIATION in this TV
receiver is the picture tube. For continued X-RAY
RADIATION protection, the replacement tube must be
exactly the same type as specified in the parts list.
3. Some parts in this TV receiver have special safety
related characteristics for X-RADIATION protection.
For continued safety, the parts replacement should
be under taken only after referring the PRODUCT
SAFETY NOTICE.
SAFETY INSTRUCTION
The service should not be attempted by anyone
unfamiliar with the necessary instructions on this TV
receiver. 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.
- 2 -
4. Completely discharge the high potential voltage of the
2／１００
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, adjustment 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
metallic 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
0.15µF 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 measurements for each exposed metallic
part.
The measured voltage must not exceed 0.3V RMS.
This corresponds to 0.5mA AC. Any value exceeding
this limit 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
components rates for a higher voltage, wattage, etc.
The replacement parts which have these special
safety characteristics are identified by 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 replacement 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.
Good earth ground
such as the water
pipe, conductor,
etc.
