I. Safety Instructions
PRECAUTIONS DURING SERVICING
1. In a ddition to safe ty, othe r parts and assemblies are
speci fied for conformance with such regulatio ns as
those applyi ng to sp urious radiation . These must
also be replace d only with specifie d replacements.
Exampl es: RF converters, tun er units, a ntenna
selection switches, RF cables, noise-blo cking
capacitors, noise-bl ocking filters, etc.
2. Use sp ecified inte rnal Wiring . Note especially:
1) Wires covered with PVC tubing
2) Do uble insulated w ires
3) Hig h voltage leads
3. Use specified i nsulating material s for haza rdous
live pa rts. Note espe cially:
1) In sulating Tape
2) PVC tubing
3) Spa cers (insu lating barriers)
4) Insula ting sheets for transistors
5) Plastic screws for fixing micro switches
4. When replacing AC primary side compo nents
(tran sformers, power cords, n oise blo cking
capacitors, e tc.), wra p ends o f wires securely about
the te rminals be fore solde ring.
5. Make sure that w ires do no t contact heat generating
parts (he at sin ks, oxide me tal fi lm resistors, fusi ble
resistors, etc.)
6. Check if replace d wires do not conta ct sharply edged
or po inted pa rts.
7. Make sure that foreign objects (screws, solder
drop lets, etc.) do not remain insi de the set.
MAKE YOUR CONTRIBUTION TO PROTECT THE
ENVIRONMENT
Used batte ries wi th the ISO symbol

Please leave the m at an ap propriate depot.
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 prod uce potentially hazardous
X-RAY RADIATION. To avoid such hazards, the high
volta ge must no t exceed the speci fied limit. The
normal va lue of the high voltage of this TV receiver
is 2 7 KV at zero b ean current (mi nimum b rightne ss).
The high voltage must no t exceed 30 KV u nder any
circu mstances. Each time when a re ceiver req uires
servici ng, the high voltage sho uld be checked. The
readi ng of the high voltage is re commended to be
reco rded as a part o f 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 repla cement 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 rep lacement should
be under taken only afte r referring the PRODUCT
SAFETY NOTICE.
SAFETY INSTRUCTION
The se rvice shoul d not be attempted by anyone
unfamiliar with the ne cessary i nstructio ns on th is TV
receiver. The fo llowing are the necessary instru ctions
to be ob served before se rvicing.
1.
An isolation transformer shoul d be con nected i n the
power li ne between the receiver and the AC line
when a service is performed o n the primary of the
conve rter tra nsformer of the set.
2.
Comply wi th all caution an d safety related provided
on th e back of the cabi net, inside the cabinet, o n the
chassis or p icture tube.
3.
To avo id a shock hazard, alw ays discharge the
pictu re tube's anode to the chassis g round be fore
removi ng the anod e cap.
The l ig h tn i ng fla sh w i th arro wh e ad symb ol ,
within an equilatera l triangle, is intended to alert
the user to the presence of uninsulated “ dangerous
voltage” within the prod uct’ s enclosure that may
be of sufficie nt mag nitud e to consti tute a risk of
electric shock to persons.
The excla mati on po i nt wi thi n a n e q ui l ate ra l
tri a n gl e is i nte n de d to a le rt th e u se r to th e
presence of important operating and maintenance
(s e rv i ci n g ) i n str u ct i o n s i n th e l i te r a tu re
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.
