Product

Safety

Notices

Some

electrical

and

mechanical

parts

have

special

safety-related

characteristics

which

are

often

not

evident

from

visual

inspection.

The

protection

they

give

may

not

be

obtained

by

replacing

them

with

components

rated

for

higher

voltage,

wattage,

etc.

Parts

that

have

special

safety

characteristics

are

identified

by

ZX

on

schematics

and

parts

lists.

A

substitute

replacement

that

does

not

have

the

same

safety

characteristics

as

the

recommended

replacement

part

might

create

shock,

fire

and/or

other

hazards.

Product

safety

is

under

review

continuously

and

new

instructions

are

issued

whenever

appropriate.

Precautions

WARNING:

Caution:

Note:

section

of

this

manual.

An

electrolytic

capacitor

installed

with

the

wrong

polarity

might

explode.

Before

servicing

units

covered

by

this

service

manual,

read

and

follow

the

Safety

Precautions

If

unforeseen

circumstances

create

conflict

between

the

following

servicing

precautions

and

any

of

the

safety

precautions,

always

follow

the

safety

precautions.

1-2-1

General

Servicing

Precautions

1.

Always

unplug

the

unit’s

AC

power

cord

from

the

4,

AC

power

source

and

disconnect

the

DC

Power

Jack

before

attempting

to:

(a)

remove

or

reinstall

any

component

or

assembly,

5.

(b)

disconnect

PCB

plugs

or

connectors,

(c)

connect

a

test

component

in

parallel

with

an

electrolytic

capacitor.

Some

components

are

raised

above

the

printed

circuit

board

for

safety.

An

insulation

tube

or

tape

is

sometimes

used.

The

internal

wiring

is

sometimes

clamped

to

prevent

contact

with

thermally

hot

components.

Reinstall

all

such

elements

to

their

original

position.

After

servicing,

always

check

that

the

screws,

components

and

wiring

have

been

correctly

reinstalled.

Make

sure

that

the

area

around

the

serviced

part

has

not

been

damaged.

Check

the

insulation

between

the

blades

of

the

AC

plug

and

accessible

conductive

parts

(examples:

metal

panels,

input

terminals

and

earphone

jacks).

Insulation

Checking

Procedure:

Disconnect

the

power

cord

from

the

AC

source

and

turn

the

power

switch

ON.

Connect

an

insulation

resistance

meter

(500

V)

to

the

blades

of

the

AC

plug.

The

insulation

resistance

between

each

blade

of

the

AC

plug

and

accessible

conductive

parts

(see

above)

should

be

greater

than

1

megohm.

Always

connect

a

test

instrument’s

ground

lead

to

the

instrument

chassis

ground

before

connecting

the

positive

lead;

always

remove

the

instru

ment’s

ground

lead

last.

1-3

Electrostatically

Sensitive

Devices

(ESD)

Precautions

Some

semiconductor

(solid

state)

devices

can

be

easily

damaged

by

static

electricity.

Such

components

are

commonly

called

Electrostatically

Sensitive

Devices

(ESD).

Examples

of

typical

ESD

are

integrated

circuits

and

some

field-effect

transistors.

The

following

techniques

will

reduce

the

incidence

of

component

damage

caused

by

static

electricity.

1-2

Immediately

before

handling

any

semiconductor

components

or

assemblies,

drain

the

electrostatic

charge

from

your

body

by

touching

a

known

earth

ground.

Alternatively,

wear

a

discharging

wrist-

strap

device.

To

avoid

a

shock

hazard,

be

sure

to

remove

the

wrist

strap

before

applying

power

to

7;

the

monitor.

After

removing

an

ESD-equipped

assembly,

place

it

ona

conductive

surface

such

as

aluminum

foil

to

prevent

accumulation

of

an

electrostatic

charge.

Do

not

use

freon-propelled

chemicals.

These

can

generate

electrical

charges

sufficient

to

damage

ESDs.

Use

only

a

grounded-tip

soldering

iron

to

solder

or

desolder

ESDs.

Use

ory

an

anti-static

solder

removal

device.

Some

solder

removal

devices

not

classified

as

“anti-static”

can

generate

electrical

charges

sufficient

to

damage

ESDs.

6.

x

Do

not

remove

a

replacement

ESD

from

its

protective

package

until

you

are

ready

to

install

it.

Most

replacement

ESDs

are

packaged

with

leads

that

are

electrically

shorted

together

by

conductive

foam,

aluminum

foil

or

other

conductive

materials.

Immediately

before

removing

the

protective

material

from

the

leads

of

a

replacement

ESD,

touch

the

protective

material

to

the

chassis

or

circuit

assembly

into

which

the

device

will

be

installed.

Caution:

Be

sure

no

power

is

applied

to

the

chassis

or

circuit

and

observe

all

other

safety

precautions.

Minimize

body

motions

when

handling

unpackaged

replacement

ESDs.

Motions

such

as

brushing

clothes

together,

or

lifting

your

foot

from

a

carpeted

floor

can

generate

enough

static

electricity

to

damage

an

ESD.
