Important Safety Precautions
Priar co shipment fram the factory, JVC prodvets are strictly inspected to conform with tha recagnized product safecy and electrical codat of
the countries in which they are to be sold. However, in arder ta maintain such comaliancs, It is aqually impartant to implement the following,
‘precautions when a set is being sarviced.
Precautions during Servicing
1. Locations requiring spacial eaution are ‘denoted by fabels and
inscriptions on the cabinet, chassis and cortain parts of the
product, Whan performing servica, be sure to read and comply
‘with these and ottiae cautionary notices appeering in the opera
tow and sarviea manuats.
2. Ports idemttied by the /\ symbol and shaded (R08) parts are
ritical for satory.
Replace anly with specified part sumbers.
Note: Parts in this category aloo ineiuda, those specifiog to
comply with Xray emision standaeds toe products uting
cathorla rey tubes. and those specified for coms
‘with varlaus regulations ‘regarding spurious radiation
3. Fuso replacement caution notice.
Coution for continued prottetion against fire hazore.
Replace only with same type and cated use(s) as specitiod.
4, ‘Ose specified Internal wiring. Nowe expecially:
1F Wires covered with PVG tubing
2} Gouble insutared wires
3) High voltage load
6. Usp specified insulating materiats for hazardous live ports. Nove
specially:
1) Insulation Tape
2) PVC tubing

7. Obeerve thot wires do not contact haat producing parts (hea
sinks, oxida matal film resistors, fusible resistors, atc.)
8. Check that renlaced wiees do not contact sharp edged or pointed
parts,
9, When a power cord has been replaced, check that 10-15 kg of
{ores in any diteetion wil nox loosen

10, Also check areas surrounding repsired toca
11, Proguots using cathode ray tubes (CRTs)
In regard to such-produets, the cathode ray tubes themselves,
the high voltage circuits, and related circuits are specified for
camplignce with recognized codes pertaining to Xray emission.
Consequently, when servicing these products, replace the cath-
ode ray tubes and other parts with only the specified aarts
Under no circumstances ettemat to madify these circuits
Unauthorized madification can increase tha high voltage value
and cause X-ray amvssian from the cathode ray tubs
12, Crimp type wire connector
In such cases as ewhen replacing the power transformer in sets
where te connections between the power cord and power
transformer primary fead wices are performed using crime type
connectors, if replacing the connactors is unavoidable, in order
to prevent safery hazards, perform carsfully anc ovscisely
according to the following steps.
4) Connector part number : £03830-001
2) Reauired tool : Canneeror crienping tool of the proper type
which will ot damage insulated piFts.
3) Replacement procedure
(1) Ramove the old connisctor by cutting the wires at 3 point

@Safety Check after Servicing
Examine the arse surrounding the repaired location for damage or deterioration. Observe that screwa, parts and wires have been returned
‘to original positions, Afterwards, perform the following tests and confirm the specified values in order ta verify comaianece with safety
andardt.
1. Insulation resistance test
Confirms the specified insulation resistance oF greater between power cord plug prongs and axtar-
nelly exposed parts of the set (RF terminols, antenna terminal, video and audio input and output
tereninals, microphone jacks, earphone jacks, eto.), See table 1 below.
2. Dialect exrength test
Confirm specified diclectclc strength’ or greater between power cord plug prongs and exposed ,
accesible parts of the sat (RF terminals, aneenna terminsis, video snd audio inpur and ourpat
terminals, evierophone jacks, earphone jacks, ete.}. See table 1 below.
3. Clnarance distances .
‘When replacing primary circuit companants, contitm specified clearance distence (a, {d") hetween
soldered terminels, and between terminals and surrounding metallic parts, See table 1 below. PT
