for

the

area

in

which

the

will

be

used.

Note

that

this

unit

will

be

seriously

damaged

if

this

setting

is

not

are

extremely

dirty,

use

a

soft

cloth,

dipped

into

a

soap

and

water

solution

or

a

weak

detergent

solution.

Wring

the

cloth

well

before

wiping

Wipe

once

again

with

a

soft

dry

cloth.

Never

use

alcohol,

paint

thinner,

benzine,

nor

a

chemically

treated

cloth

to

unit.

Such

chemicals

may

damage

FOR

SAFE

USE

OF

THIS

UNIT

■

Use

a

standard

electrical

AC

wall

outlet

1.

Use

from

an

AC

power

source

of

high

voltage,

such

as

for

air

conditioners,

is

very

dangerous.

Be

extremely

careful

not

to

make

a

connection

to

the

electrical

outlet

for

a

large

air

conditioner

or

central-heating

unit

which

uses

high

voltage,

because

there

is

the

possibility

of

fire.

2.

A

DC

power

source

cannot

be

used.

Be

sure

to

check

the

power

source

carefully,

especially

on

a

ship

or

other

place

where

DC

is

used.

■

Connection

and

removal

of

the

power

cord

plug

1.

Wet

hands

are

dangerous.

A

dangerous

electric

shock

may

result

if

the

plug

is

touched

by

wet

hands.

2.

Don't

pull

the

power

cord.

Always

grasp

the

plug;

never

pull

the

cord

itself.

■

Never

attempt

to

repair

or

reconstruct

this

unit

A

serious

electric

shock

might

occur

if

this

unit

is

repaired,

disassembled

or

reconstructed

by

unauthorized

persons,

or

if

the

internal

parts

are

accidently

touched.

■

For

families

with

children

Never

permit

children

to

put

anything,

especially

metal,

inside

this

unit.

A

serious

electric

shock

or

malfunction

could

occur

if

articles

such

as

coins,

needles,

screwdrivers,

etc.

are

inserted

through

the

ventilation

holes,

etc.

of

this

unit.

■

Turn

off

after

use

If

the

unit

is

left

for

a

long

time

with

the

power

on,

this

will

not

only

shorten

its

useful

operation

life,

but

may

also

cause

other

unexpected

trouble.

■

If

water

is

spilled

on

the

unit

Be

extremely

careful

if

water

is

spilled

on

the

unit,

because

a

fire

or

serious

electric

shock

might

occur.

Immediately

disconnect

the

power

cord

plug,

and

consult

with

your

dealer.

■

Place

the

unit

where

it

will

be

well

ventilated,

and

away

from

direct

sunlight

Place

this

unit

at

least

10

cm

(4")

away

from

wall

surfaces,

etc.,

and

away

from

direct

sunlight.

Be

careful

that

curtains

and

similar

materials

do

not

obstruct

the

ventilation

holes.

■

Keep

the

unit

away

from

heaters,

etc.

Heat

can

damage

the

external

surfaces

as

well

as

internal

circuits

and

components.

■

Avoid

spray-type

insecticides

Insecticides

might

cause

cracks

or

“cloudiness"

in

the

cabinet

and

plastic

parts

of

this

unit.

The

gas

used

in

such

sprays

might,

moreover,

be

ignited

suddenly.

■

Never

use

alcohol

or

paint

thinner

These

and

similar

chemicals

should

never

be

used,

because

they

may

damage

the

finish.

■

If

trouble

occurs

If,

during

operation,

the

sound

is

interrupted

or

indicators

no

longer

illuminate,

or

if

abnormal

odor

or

smoke

is

detected,

immediately

disconnect

the

power

cord

plug,

and

contact

your

dealer

or

an

Authorized

Service

Center.

PROTECTION

CIRCUITRY

The

protection

circuitry

may

have

operated

if

either

of

the

following

conditions

is

noticed:

•

No

sound

is

heard

when

the

power

is

turned

on.

•

Sound

stops

during

a

performance.

The

function

of

this

circuitry

is

to

prevent

circuitry

damage

if,

for

example,

the

positive

and

negative

speaker

connection

wires

are

"shorted",

or

if

speaker

systems

with

an

impedance

less

than

the

indicated

rated

impedance

of

this

unit

is

used.

If

this

occurs,

follow

the

procedure

outlined

below:

1.

Turn

off

the

power.

2.

Determine

the

cause

of

the

problem

and

correct

it.

3.

Turn

on

the

power

once

again.

Note:

When

the

protection

circuitry

functions,

the

unit

will

not

operate

unless

the

power

is

first

turned

off

and

then

on

again.
