SAFETY

PRECAUTIONS

WARNING:

Since

the

chassis

of

this

receiver

is

connected

to

one

side

of

the

Mains

Supply

during

operation,

service

should

not

be

attempted

by

anyone

unfamiliar

with

the

precautions

necessary

when

working

on

this

type

of

equipment.

The

folfowing

precautions

should

be

observed.

1.

Do

not

install,

remove,

or

handle

the

picture

tube

in

any

manner

unless

shatter-proof

goggles

are

worn.

People

not

so

equipped

should

be

kept

away

while

picture

tubes

are

handled.

Keep

picture

tube

away

from

the

body

while

handing.

.

When

replacing

chassis

in

the

cabinet,

all

the

protective

devices

are

put

back

in

place,

such

as;

barriers,

non-

metallic

knobs,

adjustment

and

compartment

cover

or

shields,

isolation

resistors-capacitors,

etc..

3.

When

service

is

required,

observe

the

original

lead

dress,

Extra

care

should

be

taken

to

assure

correct

lead

dress

in

the

high

voltage

circuitry

area.

.

Always

use

the

manufacturer's

replacement

component.

Especially

critical

components

as

indicated

on

the

circuit

diagram

should

not

be

replaced

by

other

makes.

Furthermore

where.a

short

circuit

has

occurred,

replace

those

components

that

indicate

evidence

of

overheating.

5,

Before

returning

a

serviced

receiver

to

the

customer,

the

service

technician

must

thoroughtly

test

the

unit

to

be

certain

that

it

is

completely

safe

to

operate

without

danger

of

electrical

shock,

and

be

sure

that

no

protective

device

built

into

the

instrument

by

the

manufacturer

has

became

defective,

or

inadvertenly

defeated

during

servicing.

Therefore,

the

following

checks

are

recommended

for

the

continued

protection

of

the

customers

and

service

technicians,

INSULATION

Insulation

resistance

between

the

mains

poles

and

any

accessible

metal

parts

should

not

be

less

than

7MQ

at

500V

DC.

Also,

no

flashover

or

breakdown

should

occur

during

the

dielectric

strength

test,

to

apply

4KV

AC

for

one

minute

between

the

mains

poles

and

any

accessible

metal

parts.

X-RADIATION

TUBES:

Tie

primary

source

of

X

radiation

in

this

receiver

is

the

picture

tube.

The

tube

utilized

in

this

chassis

is

specially

constructed

to

limit

X

For

continued

X

protection,

the

replacement

tube

must

be

the

same

type

as

the

original,

HITACHI

approved

type.
