I. Safety Instru ctions
CAUTION
RISK OF ELECTRIC SHOCK
DO NO T OPEN
The l ightning fla sh w ith arro whead symb ol,
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.
CAUTIO N: TO REDUCE THE RISK OF ELECTRIC
SHO CK, DO NOT REMOVE COVER (OR BACK). NO
USER-SERVI CEABLE PART S INSIDE. REFER
SERVICING TO QUALIFI ED SERVICE PERSONNEL
O NLY.
PRECAUTIONS DURING SERVICING
1. In a ddition to safety, other parts and assemblies are
speci fied for conformance with such regulations as
those applyi ng to spurious radiation. These must
also be replaced only with specified replacements.
Exampl es: RF converters, tuner units, antenna
selection switches, RF cables, noise-blocking
capacitors, noise-bl ocking filters, etc.
2. Use sp ecified internal Wiring. Note especially:
1) Wires covered with PVC tubing
2) Do uble insulated wires
3) Hig h voltage leads
3. Use specified i nsulating materials for hazardous
live pa rts. Note especially:
1) In sulating Tape
2) PVC tubing
3) Spa cers (insulating barriers)
4) Insulating sheets for transistors
5) Plastic screws for fixing micro switches
4. When replacing AC primary side compo nents
(tran sformers, power cords, n oise blocking
capacitors, e tc.), wrap ends of wires securely about
the te rminals before soldering.
5. Make sure that w ires do not contact heat generating
parts (he at sinks, oxide metal film resistors, fusible
resistors, etc.)
6. Check if replace d wires do not contact sharply edged
or po inted parts.
7. Make sure that foreign objects (screws, solder
drop lets, etc.) do not remain insi de the set.
MAKE YOUR CONTRIBUTION TO PROTECT THE
ENVIR ONMENT
Used batteries with the ISO symbol
for recycling a s well as small
accumu lators (rechargeable batteries), mini-batteries
(cell s) and starter batteries should not be thrown
into the garbage can.
Please leave them at an appropriate depot.
The excla mation po int wi thin a n equilateral
tri angle is intended to a lert th e user to the
presence of important operating and maintenance
(servici n g) instr u ct i o n s i n th e liter a tu re
accompanying the appliance.
W ARNING:
Before servicing this TV receiver, read the X-RAY
RADIATION PRECAUTION, SAFETY INSTRUCTION
and PRODUCT SAFETY NOTICE.
X-RA Y RADIATION PRECAUTION
1. Excessively high can prod uce potentially hazardous
X-RAY RADIATION. T o avoid such hazards, the high
volta ge must not exceed the specified limit. The
normal va lue of the high voltage of this TV receiver
is 2 7 KV at zero bean current (minimum brightness).
The high voltage must not exceed 30 KV under any
circu mstances. Each time when a re ceiver requires
servici ng, the high voltage should be checked. The
readi ng of the high voltage is re commended to be
reco rded as a part of the service record, It is
important to u se an accurate and reliable high
voltage meter.
2. The only source of X-RAY RADIATION in this TV
receiver is the picture tube. For con tinued X-RAY
RADIATION protectio n, the replacement tube must be
exactly the sa me type as specified in th e parts list.
3. Some parts in this TV receiver have special safety
related characteristics fo r X-RADIATION protection.
For continued safety, the parts replacement should
be under taken only afte r referring the PRODUCT
SAFETY NOTICE.
SAFETY IN STRUCTION
The se rvice should not be attempted by anyone
unfamiliar with the ne cessary instructions on this TV
receiver. The fo llowing are the necessary instructions
to be ob served before servicing.
1. An isolation transformer shoul d be connected in the
power li ne between the receiver and the AC line
when a service is performed on the primary of the
conve rter transformer of the set.
2. Comply wi th all caution and safety related provided
on th e back of the cabinet, inside the cabinet, on the
chassis or p icture tube.
3. T o avoid a shock hazard, always discharge the
pictu re tube's anode to the chassis g round before
removi ng the anode cap.
- 2 -
4. Completely discharge the high potential voltage of the
picture tube before handli ng. The picture tube is a
vacuum and if bro ken, the glass will explode.
5. When rep lacing a MAIN PCB in the cabinet, always
be certai n that all protective are installed properly
such as control knobs, adjustment co vers or shields,
barri ers, isolation resistor networks etc.
6. When se rvicing is required, observe the original lead
dressing. Extra precau tion should be given to assure
correct lead dressing in the high voltage area.
7. Keep wires away from high voltage or high te mpera
ture components.
8. Befo re returning the set to the customer, al ways
perform an AC leaka ge current check on the exposed
meta llic parts of the cabinet, such as anten nas,
termin als, screwheads, metal overlay, control shafts,
etc., to be sure the set is safe to operate without
danger of electrica l shock. Plug the AC line cord
directly to the AC outlet (do not use a line isolation
transformer d uring this check). Use an AC voltmeter
havin g 5K ohms volt sensitivity or more in the
following manner.
Conne ct 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 vol tage across the combination of
the 1 .5K ohm resistor and 0.15 uF capacitor. Reverse
the AC p lug at the AC outlet and repeat the AC
volta ge measurements for each exposed metallic
part.
The me asured voltage must not exceed 0.3V RMS.
This correspo nds 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
betwe en accessible exposed metal parts and power
cord plug prongs with the power switch "ON". The
resi stance should be more than 6M ohms.
PRODUCT SA FETY NOTICE
Many e lectrical 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 necessari ly be obtained by using replacement
compon ents rates for a higher voltage, wattage, etc.
The replacemen t parts which have these special
safety characteristics are identified by marks on
the schematic diagram and on the parts list.
Before replacin g any of these components, read the
parts list in thi s manual carefully. The use of
substitute re placement parts which do not have the
same safety characteristics as specified in the parts
list may cre ate shock, fire, X-RAY RADIATION or
other h azards.
Good earth ground
such as the water
pipe, conductor,
etc.
