SAFETY PRECAUTIONS

1. The d esign of th is prod uct con tains special hard wa re, ma ny

circuit s and components specially for safety purposes. For

con tinu ed prot ection , n o chan g es sh ou ld b e ma de to the o rig inal

d esign unless a uth or ized in writin g by th e manu fact urer .

Replacemen t p ar ts must b e ident ic al to thos e u sed in th e or igin al

circu it s. S ervice sho uld b e p erformed by qualif ied p ers on nel

on ly.

2. Alte ration s of t he desig n or cir cuitry of t he prod ucts sh ould not be

made. Any design alterations or additions will void the

manu fact urer's warra nt y and will f urther r elieve t he ma nu factu rer

of r esp onsibility for per sona l injury or p r op erty d amag e result in g

th er efrom.

3. Man y electrical an d mech anica l p arts in th e prod ucts ha ve

special safety-related characteristics. T hese characteristics are

oft en no t e viden t f rom visua l insp ection n or ca n t he pro tect ion

aff orde d by th em nece ssarily b e ob tain ed b y u sing rep lacemen t

compo ne nts ra ted f or hig he r voltag e, watt ag e, etc. Rep lacemen t

p arts wh ic h ha ve th ese sp ecial s afet y char act erist ics are

identified in the parts list of Servic e manual. El ec tric al

components having su ch features are identified by shading

on the sche matics and by (!

! ) on the parts list in Service

manual. The us e of a sub stitu te rep la cemen t which do es n ot

h ave th e same saf ety ch ar act er ist ics as t he r ecommen de d

replac ement part shown in the p arts list of S ervice man ual may

cause shock, fire, or other hazards .

4. Do n't shor t between the LIVE side ground and ISOLATED

(NEUTRAL) side ground or EARTH side ground when

repairing.

Some model's power circuit is partly different in the GND. The

diff erenc e of the G ND is sho wn b y th e LIV E : (") side GND, the

ISO LATE D(NEUTRAL) : (#) side G ND and EARTH : ($) side

GND. Do n't shor t b et ween th e LIV E sid e GND an d

ISO LATE D(NEUTRAL) side GND or EARTH side GND and

n ever mea sure wit h a m ea sur ing a ppa ratus (oscillo scop e etc.)

th e LI VE sid e GND an d IS OLA TED(NE UTRAL) side G ND or

EARTH sid e GND at the s ame time.

If above note will not be kept, a fuse or any parts will be broken.

5. If any repair has been made to the chassis, it is recommended

th at t he B1 set ting shou ld b e ch ecke d or adju ste d (Se e

ADJUSTMENT OF B1 POW E R SUPPL Y).

6. The high volta ge app lie d t o th e pictu re tu be must con for m wit h

th at sp ecified in S ervice man ual. E xcessive h igh volt ag e ca n

cau se an incre ase in X- Ray emission, arcing an d possib le

component damage, therefore operation under excessive high

voltage conditions should be kept to a minimum, or should be

preve nt ed. If s ever e arc in g occurs, rem ove t he AC power

immed iately and de termine th e ca use b y visua l insp ect ion

(in corr ect installat ion, cr acke d or m elte d high vo lt age harn ess,

7. Do n ot c hec k high volt ag e b y dr awing an arc. Use a high volt ag e

meter or a hig h v oltag e prob e wit h a V TVM. Discha rg e th e

picture tube before attempting meter connection, by connecting

a clip lead to th e grou nd f rame a nd c onn ectin g the oth er end of

the lead through a 10kΩ 2W resistor to the an od e b utt on .

8. W hen se rvice is requ ire d, obser ve th e origina l lea d dress. E xtra

prec aut ion sh ou ld b e g ive n t o assure correct lea d dr ess in th e

9. Isolation Check

(Safety for Electrical Shock Hazard)

Af ter re-ass emblin g th e p rodu ct, always perf orm an isolat ion

ter minals, video /au dio input and ou tpu t t er min als, Control kn obs,

metal cabin et, scr ewhe ad s, ear ph one jack, con trol shaf ts, etc.)

to be su re th e p rodu ct is s af e t o o pe rate withou t dan ger of

elect rical shoc k.

(1) Dielectric Strength Test

The iso lation be tween the A C prima ry circu it and all metal p arts

exp ose d t o th e us er, particularly any e xp os ed met al p art h aving a

return p ath to t he chass is should withs tan d a volt age of 3 000 V

AC (r.m.s.) for a period of one second.

(. . . . W it hstand a vo lt ag e of 1 10 0V A C ( r .m. s.) t o an ap plianc e

rated up to 12 0V , an d 3 00 0V AC (r .m. s.) to an ap plian ce rat ed

200V or more, for a period of one second.)

This method of test requires a t est equipment not generally found

in t he servic e trad e.

(2) Leakage Current Check

Plug th e A C lin e c ord d irect ly into th e A C ou tlet (d o n ot use a lin e

isolatio n tr ansf ormer du rin g this check.). Usin g a " Lea kag e

Current Tester", me asure th e leakag e cu rre nt f rom each exp osed

metal p art of the ca bine t, p art icu larly any e xpos ed me tal p ar t

h aving a re tur n pa th to t he ch assis , t o a kn own go od ea rt h

0.5mA AC (r.m.s.).

Howeve r, in tropic al ar ea , th is must no t exce ed 0.2 mA AC

(r.m.s.).

" Alte rnate Che ck Method

Plug th e A C lin e c ord d irect ly into th e A C ou tlet (d o n ot use a lin e

isolatio n tr an sformer during t his che ck.). Use an AC vo lt meter

h aving 100 0 oh ms per volt or more sens it ivity in th e fo llowing

mann er. Con nec t a 1 50 0Ω 10W res ist or para lle le d b y a 0 .1 5µF

across th e res ist or with the AC vo ltmeter. Move th e r esistor

con nec tion to e ach exp ose d metal part, p art icularly a ny exp osed

metal p art having a r etu rn pat h to t he ch assis, and m easur e th e

AC voltag e ac ross the res ist or. No w, reverse th e plu g in the AC

ou tlet and re pe at eac h mea suremen t. Any volt ag e measu re d

must not exc eed 0.7 5V AC (r.m. s.). This c orresponds to 0 .5mA

AC (r.m.s.).

However, in tropica l are a, this must not exceed 0.3V AC ( r.m.s.).

This corresponds to 0.2mA AC (r.m.s.).
