Topreventtherisk offire, smoke, or electrical shock and toensuresafeoperation, please be
suretofollowthesafetyguidelines below.
1. Atplaces wherespecial caution isrequired, thenecessarysafety
precautionsareclearlylabeledorprinted, forexample, on the
cabinet, oron thepartconcerned. Please follow these safety
precautions, and alsothose listedintheOwner'sManual.
2. Parts whichhavea ;markinthecircuitdiagramorintheparts
list areessential forsafety. Whenreplacing these parts, besureto
use onlythespecifiedparts.
3. Use thespecifiedtypes forinternal wiring (double-insulated
wiring, etc.).
4. Whenreplacing parts on theACprimaryside(powertransformer,
electricswitch, electrical cord, noise-prevention condenser, etc.),
wind theleadwireand secureitbysoldering.
5. Donotlet thewiring comeintocontact withheat-emitting devices
(fuse resistor, radiatorplate, etc.).
6. Whenreplacing thewiring, make surethat itisnotincontact with

theunfinishedorrough edgeofapart.
7. Whenreplacing thepowercord(exceptfortheplug-intype), tug it
fromvariousdirectionstoconfirm that itdoes notslipoutofplace.
8. Spacing
Ifsoldering was doneon theACprimarycircuit, confirm that the
interval betweenthesolderedterminalsorbetweentheterminal
and surrounding metallicparts isat least theminimumrequired
(betweentheprimarycircuitand thechassis:atleast 6.5mm;
betweenprimarycircuitterminals:at least 4.0mm;between
primarycircuitterminalsand secondarycircuitterminals:at least
6.5mm.).

isevident.
4. Afterservicing, besuretorestoretheleaddress, insulation
barriers, insulation papers, shields, etc.
5. Beforereturning theservicedequipmenttothecustomer, besure
tomake thefollowing insulation resistance test topreventthe
customerfrombeing exposedtoashock hazard.
2.2. Insulation Resistance Test
1. Unplug thepowercordand shorttheprongsoftheplug witha
jumperwire.
2. Turnon thepowerswitch.
3. Measuretheresistance valuewithanohmmeterbetweenthe
