IMPORTANT

SAFETY

PRECAUTIONS

Prior

to

shipment

from

the

factory,

the

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

operation

and

service

manuals.

2.

Parts

identified

by

the

A\

symbol

and

shaded

(

§%)

parts

are

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

various

regulations

regarding

spurious

radiation

When

replacing

AC

etc.)

wrap

ends

of

wires

securely

about

the

termin-

als

before

soldering.{Fig.

3.

Use

Specified

internal

wiring.

Note

especially:

1)

Wires

covered

with

PVC

tubing

2)

Double

insulated

wires

3)

High

4.Use

specified

insulating

materials

for

hazardous

live

parts.

Note

especially:

1)

Insulation

Tape

2)

PVC

3)

Spacers

4)

Insulation

sheets

for

6.

Observe

that

wires

do

not

contact

heat

producing

parts

(heatsinks,

oxide

resistors,

fusible

resistors,

;

etc.)

Power

cord

7.

Check

that

replaced

wires

do

not

contact

sharp

edged

or

pointed

parts

8.When

a

power

cord

has

been

replaced,

check

that

10-15Kg

of

force

in

any

direction

will

not

loosen

it{Fig.

9.

Also

check

areas

surrounding

repaired

locations.

10.

Products

using

cathode

ray

tubes

(CRTs)

In

regard

to

such

products,

the

cathode

ray

tubes

themselves,

the

high

voltage

circuits,

and

are

specified

for

compliance

with

recognized

codes

pertaining

to

X-ray

emission.

Consequently.

when

servicing

these

Products,

replace

the

cathode

ray

tubes

and

other

parts

with

only

the

parts

specified.

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.

SAFETY

CHECK

AFTER

SERVICING

Examine

the

area

surrounding

the

repaired

location

for

damage

or

deterioration.

Observe

that

screws,

parts

and

wires

have

been

returned

to

original

positions.

Afterwards,

perform

the

following

tests

and

confirm

the

specified

values

in

order

to

verify

compliance

with

safety

standards.
