SAFETY

INSTRUCTIONS

SAFETY

CHECK

AFTER

SERVICING

Confirm

the

specified

insulation

resistance

between

power

cord

plug

prongs

and

externally

exposed

parts

of

the

set

is

greater

than

10

Mohms,

but

for

equipment

with

external

antenna

terminals

(tuner,

receiver,

etc.)

and

is

intended

for

or

[A],

specified

insulation

resistance

should

be

more

than

2.2

Mohms

(ground

terminals,

microphone

jacks,

headphone

jacks.

line-in-out

jacks

etc.)

PRECAUTIONS

DURING

SERVICING

1.

Parts

identified

by

the

A\

symbol

parts

are

critical

for

safety.

Replace

only

with

parts

number

specified.

2.

In

addition

to

safety,

other

parts

and

assemblies

are

specified

for

conformance

with

such

regulations

as

those

applying

to

spurious

radiation.

These

must

also

be

replaced

only

with

specified

replacements.

Examples:

RF

converters,

tuner

units,

antenna

selector

switches,

RF

cables,

noise

blocking

capacitors,

noise

blocking

filters,

etc.

3.

Use

specified

internal

wiring.

Note

especially:

1)

Wires

covered

with

PVC

tubing

2)

Double

insulated

wires

3)

High

voltage

leads

4.

Use

specified

insulating

materials

for

hazardous

live

parts.

Note

especially:

1)

Insulation

Tape

2)

PVC

tubing

3)

Spacers

(Insulating

Barriers)

4)

Insulation

sheets

for

transistors

5)

Plastic

screws

for

fixing

microswitch

(especially

in

turntable)

5.

When

replacing

AC

primary

side

components

(transformers,

power

cords,

noise

blocking

capacitors,

etc.),

wrap

ends

of

wires

securely

about

the

terminals

before

soldering.

—

c>

Observe

that

wires

do

not

contact

heat

producing

parts

(heatsinks,

oxide

metal

film

resistors,

fusible

resistors,

etc.).

Check

that

replaced

wires

do

not

contact

sharp

edged

or

pointed

parts.

Also

check

areas

surrounding

repaired

locations.

Use

care

that

foreign

objects

(screws,

solder

droplets,

etc.)

do

not

remain

inside

the

set.

220V,

or

240V

as

required.

If

your

machine’s

can

be

converted:

Before

connecting

the

power
