Important

Safety

Precautions

Prior

to

shipment

from

the

factory,

JVC

products

are

strictly

inspected

to

conform

with

the

recognized

product

safety

and

electrical

codes

of

the

countries

in

which

they

are

to

be

sold.

However,

in

order

to

maintain

such

compliance,

it

is

equally

important

to

implement

the

following

precautions

when

a

set

is

being

serviced.

@

Precautions

during

Servicing

|

1.

Locations

requiring

special

caution

are

denoted

by

labels

and

inscriptions

on

the

cabinet,

chassis

and

certain

parts

of

the

product.

When

performing

service,

be

sure

to

read

and

comply

with

these

and

other

cautionary

notices

appearing

in

the

opera-

tion

and

service

manuals.

Parts

identified

by

the

/\

symbol

and

shaded

critical

for

safety.

Replace

only

with

specified

part

numbers.

Note:

Parts

in

this

category

also

include

those

specified

to

comply

with

X-ray

emission

standards

for

products

using

cathode

ray

tubes

and

those

specified

for

compliance

with

varioys

regulations

regarding

spurious

radiation

emission.

)

parts

are

Fuse

replacement

caution

notice.

Caution

for

continued

protection

against

fire

hazard.

Replace

only

with

same

type

and

rated

fuse(s)

as

specified.

.

Use

specified

internal

wiring.

Note

especially:

1)

Wires

covered

with

PVC

tubing

2)

Double

insulated

wires

3)

High

voltage

leads

Use

specified

insulating

materials

for

hazardous

live

parts.

Note

especially:

1)

Insulation

Tape

3)

Spacers

5)

Barrier

2)

PVC

tubing

4)

Insulation

sheets

for

transistors

.

When

replacing

AC

primary

side

components

(transformers,

power

cords,

noise

blocking

capacitors,

etc.)

wrap

ends

of

wires

securely

about

the

terminals

before

soldering.

.

Observe

that

wires

do

not

contact

heat

producing

parts

(heat-

sinks,

oxide

metal

film

resistors,

fusible

resistors,

etc.)

.

Check

that

replaced

wires

do

not

contact

sharp

edged

or

pointed

parts.

9.

When

a

power

cord

has

been

replaced,

check

that

10—15

kg

of

force

in

any

direction

will

not

loosen

it.

Power

cord

.

Also

check

areas

surrounding

repaired

locations.

.

Products

using

cathode

ray

tubes

(CRTs)

In

regard

to

such

products,

the

cathode

ray

tubes

themselves,

the

high

voltage

circuits,

and

related

circuits

are

specified

for

compliance

with

recognized

codes

pertaining

to

X-ray

emission.

Consequently,

when

servicing

these

products,

replace

the

cath-

Ode

ray

tubes

and

other

parts

with

only

the

specified

parts.

Under

no

circumstances

attempt

to

modify

these

circuits.

Unauthorized

modification

can

increase

the

high

voltage

value

and

cause

X-ray

emission

from

the

cathode

ray

tube.

where

the

are

performed

using

crimp

connectors,

if

replacing

the

is

unavoidable,

in

order

to

prevent
