I. Safety Instructions
CAUTION: TO REDUCE THE RISK OF ELECTRIC
SHOCK, DO NOT REMOVE COVER (OR BACK). NO
USER-SERVICEABLE PARTSINSIDE. REFER
SERVICING TO QUALIFIED SERVICE PERSONNEL
ONLY.
The ligh tn in g flas h with a rrow hea d sym bo l,
A
within an e q uilateral triangle, is intended to alert
the user to the presence of uninsulated "dangerous
voltage” within the p roduct’ s enclosure that may
1 be of sufficient m a g nitude to constitute a risk of
electric shock to persons.
A
The e xcla ma tio n p o int within an e qu ilate r a l
tria ngle is in te nde d to ale rt the use r to the
presence of im portant operating and maintenance
. (s e rv ic in g ) in s tru c t io n s in th e lite ra tu re
accom panying the appliance.
PRECAUTIONS DURING SERVICING
1. In addition to safety, o ther parts and assemblies are
specified for conform ance with such regulation s as
those applying to s p u rio u s rad iation. These must
also be replaced only w ith specified replacements.
Exam ples: RF converters, tuner units, antenna
selection switches, RF cables, no ise-blocking
cap acitors, noise-blocking filters, etc.
2. Use specified internal W iring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
3. Use specifie d insulating m aterials for hazardous
live parts. Note e specially:
1) Insulating Tape
2) PVC tubing
3) S pacers (insulating barriers)
4) Insulatin g sheets for transistors
5) P lastic screw s for fixing micro sw itches
4. When replacing A C prim ary side com ponents
(transformers, pow e r cords, noise blocking
cap acitors, etc.), w rap ends of wires secure ly about
the terminals before soldering .
Make sure that wire s 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, so lder
droplets, etc.) do not rem ain inside the set.
SAFETY INSTRUCTION
The service should not be attempted by anyone
unfa miliar w ith the nece ssary in stru ctions on this TV
receiver. The following are the necessary instruction s
to be observed before servicing.
1. An isolation transformer shou ld be connected in the
power li ne between the receiver and the AC line
when a service is perfo rmed on the primary of the
converter transform er of the set.
2. Com ply w ith all caution and safety related provided
on the back of the cab inet, inside the cabinet, on the
chass is or picture tube.
3. To avoid a shock hazard, always disch a rge the
picture tube's anode to the chassis ground before
rem oving the an ode cap.
MAKE YOUR CONTRIBUTION TO PROTECT THE
ENVIRONMENT
Used batteries with the ISO symbol
for recycling as w e ll as small
accu m ulators (rechargeable batteries), m ini-ba tteries
(cells) and sta rte r batteries should not be thrown
into the garbage can.
Please leave them at an a p p ropriate depot.

4. C ompletely discharge the high potential voltage of the
picture tube before ha nd ling. The picture tube is a
vacuum and if broken, the glass will explode.
5. When repla cing a MAIN PCB in the cabinet, always
be certain that all protective are installed properly
such as control knobs, a d justm ent cove rs o r shields,
barriers, isolation resistor networks etc.
6. When servicing is required, observe the origin al lead
dressing. Extra precaution should be given to assure
correct lead dressing in the high volta g e area.
7. Keep wire s aw ay from high voltage or high tempera
ture components.
8. Before returning the set to the customer, always
perform an AC leaka g e current check on the exposed
m e tallic parts of the ca binet, such as antenn as,
terminals, screwheads, metal overlay, control shafts,
etc., to be sure the set is safe to opera te w itho u t
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 voltm eter
having 5K ohms volt sensitivity or more in the
following manner.
Conn e c t a 1.5K ohm 10 watt resistor p a ralleled by a
0.15|jF AC type capacitor, between a go o d earth
ground (water pipe, conductor etc.,) and the exposed
metallic parts, one at a tim e.
Measure the AC vo lta g e across the combinatio n 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 fo r each exposed m etallic
part.
The m easured voltage must not exceed 0.3V RMS.
This corresponds to 0.5mA AC. A ny value exceeding
this limit constitutes a potential shock hazard and
must be correcte d im mediately.
The resistance measurement sho uld be done
between accessib le exposed metal parts and power
cord plug prongs with the power switch "ON". The
resistance should be more than 6M ohm s.
PRODUCT SAFETY NOTICE
Many electrical and m echanical 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
cann ot necessarily be obtained by using replacem ent
components rates for a highe r volta ge, wattage, etc.
The re p lacem ent parts which have these spe cial
safety characteristics are identified b y ^ marks on
the schem atic diagram and on the parts list.
Before rep lacing any of these com pon ents, read the
parts list in this m anual carefully. The use of
substitute repla cem ent parts which do not have the
same safe ty cha racteristics as spe cified in the parts
list may create shock, fire, X-RAY RADIATION or
other hazards.
