● Primary side and Secondary side
Themonitor'scircuitwhichisdividedintothePrimaryside
andSecondaryside,iselectricallyisolated.Donottouchthe
primaryside,ordonottouchboththeprimarysideandthe
secondarysidesimultaneously.Failingtoobservethe
instructioncancauseelectricshockandthisisvery
dangerous.Whenmakingmonitoradjustments,useanon-
conductivedriverandmakeadjustmentwithouttouchingany
partotherthantheAdjustmentV.R.andknob.Also,besure
nottocauseashort-circuittothePrimarysideandSecondary
side.Ifshort-circuited,itcancauseelectricshockor
malfunctioning,whichisverydangerous.
● High-tension Voltage
Someofthepartsinsidemonitoraresubjecttohigh-tensionvoltageinexcessof20,000voltsand
verydangerous.Therefore,donottouchthemonitorinterior.Shouldsoldering&paperwastes,
etc.bemixedinthemonitorinterior,turnthepoweroffsoasnottocausemalfunctioningorfire
hazard.
● Static Electricity
TouchingtheCRTsurfacesometimescausesyoutoslightlyfeelelectricity.Thisisbecausethe
CRTsurfacesaresubjecttostaticandwillnotadverselyaffectthehumanbody.
● Installation and removal
EnsurethattheMagnetizerCoil,FBT(Fly-BackTransformer),AnodeLeadandFocusLeadare
notpositionedclosetothesheetmetalwork'ssharpedges,etc.andavoiddamagingtheinsulated
portionssoasnottocauseelectricshockandmalfunctioning.(Forthenameofparts,refertothe
aboveFigures).

● Connecting the CRT and PCB
ForcombiningtheCRTandPCB,usethespecifiedpartNo.tomaintainthestatusofadjustments
madeatthefactory.TheanodeoftheCRTitselfwillbeaccumulativelychargedastimeelapses,
generatinghigh-tensionvoltagewhichisverydangerous.Themonitorshouldbeusedwiththe
Chassis,CRTandPCBassembled.Whenrepair,etc.isrequiredatthetimeofmalfunctioning,
besuretosenditinan"asisassembled"condition.Ifthesearedisassembled,what'schargedto
saidhightensionvoltagecanbedischarged,causingaveryhazardoussituation.Therefore,under
nocircumstancesshoulditbedisassembled.
● Whenperformingsuchworkasinstallingandremovingthemonitor,insertinganddisconnecting
theexternalconnectorstoandfrommonitorinteriorandthemonitor,besuretodisconnectthe
powerconnector(plug)beforestartingthework.Proceedingtheworkwithoutfollowingthis
instructioncancauseelectricshockormalfunctioning.
●Usingthemonitorbyconvertingitwithoutobtainingapriorpermissionisnotallowed.SEGA
shallnotbeliableforanymalfunctioningandaccidentcausedbysaidconversion.
