SAFETY PRECAUTIONS
1. The design of this product contains special hardware, many circuits and components specially for safety purposes. For continued protection,
no changes should be made to the original design unless authorized in writing by the manufacturer. Replacement parts must be identical to
those us ed in th e origin al circ u its . Service sh oul d be perform ed by qualif i ed p ers onnel only.
2. Alter ations of th e desi gn or cir cuitr y of th e product s shoul d not b e made. A ny des ign alt erati ons or add itions will void the m anufactu rer's
warranty and will further relieve the manufacturer of responsibility for personal injury or property damage resulting therefrom.
3. Many electrical and mechanical parts in the products have special safety-related characteristics. These characteristics are often not evident
from vis u al inspec t i on n or can th e protec ti on af forded by them neces saril y b e obt ained b y us i ng r eplacem ent c om p on ents rated for high er
voltag e, watt age, etc . Rep lac emen t part s whic h h ave th ese s pec ial saf et y ch aract eris tics are i dentif i ed in th e par ts lis t of S ervic e manu al.
Electric al co mponents hav ing su ch f e atu r es are identif i ed by shading on t he sch em atics an d b y ( !) on the par ts list i n Serv i ce
manual.
shown in the parts list of Service manual may cause shock, fire, or other hazards.
4.
Don't short 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 difference of the GND is shown by the LIVE : (") side GND, the
ISOLATED(NEUTRAL) : (#) side GND and EARTH : ($) side GND. Don't short between the LIVE side GND and ISOLATED(NEUTRAL)
side GND or EARTH side GND and never measure with a measuring apparatus (oscilloscope etc.) the LIVE side GND and
ISOLATED(NEUTRAL) side GND or EARTH side GND at the same time.
If above not e wi ll n ot be kept, a fuse or any parts will be brok en.
5. If any repair has been made to the chassis, it is recommended that the +B setting should be checked or adjusted (See +B ADJUSTMENT).
6. The high vol tage appli ed to the pictu re tube must conf orm with that spec ified in Servic e manual. Excess ive high voltage c an cause an
increas e in X- R ay emiss i on, arc ing an d poss ibl e comp onen t d amag e, th eref or e oper ati on und er exc ess ive h ig h vol tag e condi ti ons s hould
be kept t o a min imum, or sh ould b e preven ted. If s evere arci ng occurs, r emo ve the AC power imm ediatel y and determ ine t he c ause by
visual inspecti on (incorrec t inst allation , cr ack ed or melt ed hig h voltage har n ess , poor solderi ng, etc.). T o main t ain th e pr op er minimum level
of soft X-Ray em is s i on, compon en ts in t h e hi gh vol t ag e c ir c uit ry inc l ud in g the p ic ture tub e mus t be th e exact replacements or alternatives

The us e of a s ubs titut e replac em en t w hic h d oes not ha ve the same saf et y c h aracteris tics as the rec om m en d ed replac em en t part
7. Do not c h eck h igh vol tag e by dr awin g an arc . Us e a h igh volt ag e meter or a high volt ag e prob e with a VT V M. Disc har ge t he pic ture tube
before attempting meter connection, by connecting a clip lead to the ground frame and connecting the other end of the lead throug h a 10k
2W resistor to the anode button.
8. When service is required, observe the original lead dress. Extra precaution should be given to assure correct lead dress in t he high volt ag e
circuit ar ea. W here a short c irc uit has occ urr ed, thos e c omp onent s t hat i ndic at e evid enc e of over heat ing s hou ld be r epl ac ed. A lways use
the manufacturer's replacement components.
