Precaution

1.

The

contains

special

check

Many

circuits

and

components

specially

for

safety

purposes.

For

continued

protection,

no

changes

should

be

made

to

the

original

design

unless

authorized

in

writing

by

the

manufacturer.

Replacement

parts

must

be

identical

to

those

used

in

the

original

circuits.

Service

should

be

per-

formed

by

qualified

personnel

only.

.

Alterations

of

the

design

or

circuitry

of

the

product

should

not

be

made.

Any

design

alterations

or

additions

will

void

the

manufacturer’s

warranty

and

will

further

relieve

the

manufacturer

of

responsibility

for

personal

injury

or

property

damage

resulting

therefrom.

.

Many

electrical

and

mechanical

parts

in

the

product

have

special

safety-related

characteristics.

These

charac-

teristics

are

often

not

evident

from

visual

inspection

nor

can

the

protection

afforded

by

then

necessarily

be

obtained

by

using

replacement

components

rated

for

higher

voltage,

wattage,

etc.

Replacement

parts

which

have

these

special

safety

characteristics

are

identified

in

the

parts

list

of

Service

manual.

Electrical

components

having

such

features

are

identified

by

(

Z\)

on

the

schematics

and

parts

list

in

manual.

The

use

of

a

substitutue

which

does

not

have

the

same

safety

characterisitics

as

the

recommended

replacement

part

shown

in

the

parts

list

in

manual

may

create

shock,

fire,

or

other

hazards.

When

service

is

required,

the

(Safety

for

electrical

shock

hazard)

After

re-assembling

the

product,

always

perform

an

isolation

check

on

the

exposed

metal

parts

of

the

Pro-

ducts

(antenna

terminals,

knobs,

metal

cabinet,

screw

heads,

earphone

jack,

control

shafts,

etc.)

to

be

sure

the

product

is

safe

to

operate

without

danger

of

electrical

shock.

Do

not

use

a

line

isolation

transformer

during

this

check.

e

Plug

the

AC

line

cord

directly

into

the

AC

outlet.

Us-

ing

a

‘‘Leakage

Current

Tester’’,

measure

the

leakage

current

from

each

exposed

metal

part

of

the

cabinet,

particularly

any

exposed

metal

part

having

a

return

path

to

the

chassis,

to

a

known

good

earth

ground

(water

pipe,

etc,).

Any

leakage

current

must

not

ex

ceed

e

Alternate

method.

Plug

the

AC

line

cord

directly

into

the

AC

outlet.

Use

an

AC

voltmeter

having

1,000

ohms

per

or

mroe

in

the

following

manner.

Connect

a

uF

AC-type

capaci-

tor

between

an

exposed

metal

part

and

a

known

good

earth

ground

(water

pipe,

etc.).

Measure

the

AC

voltage

across

the

resistor

with

the

AC

voltmeter.

Move

the

resistor

connection

to

each

exposed

metal

part,

particularly

any

exposed

metal

part

having

a

return

path

to

the

chassis,

and

measure

the

AC

volt-

age

across

the

resistor.

Now,

reverse

the

plug

in

the

outlet

and

repeat

each

measurement.

Any
