Installation

of

turntable

platter

1.

Place

the

turntable

platter

on

the

center

spindle.

(Fig.

2)

Put

your

fingers

through

the

two

holes

in

the

platter,

and

line

them

up

with

the

two

recesses

underneath.

Follow

the

reverse

procedure

if

itis

necessary

to

remove

the

platter.

Note:

The

rotor

is

connected

to

the

underside

of

the

turntable

platter.

(The

magnet

of

the

motor

is

attached

to

the

turn-

table

platter.)

To

maintain

optimum

performance,

extra

care

should

be

taken

to

prevent

adhesion

of

dust

or

iron

filings

to

the

magnet

and

not

to

damage

the

magnet

by

dropping

it.

Do

not

remove

or

loosen

the

screws.

Should

the

position

of

the

fixed

magnet

be

altered

by

loosening

the

securing

screws,

the

rated

performance

of

the

unit

cannot

be

guar-

anteed.

If

the

pre-selected

voltage

is

different

from

your

local

-

voltage,

turn

the

AC

tine-voltage

selector

with

a

screw-

driver

so

that

it

corresponds

to

your

local

voltage.

The

AC

where

there

is

little

the

unit

away

from

the

speakers

so

that

it

will

be

subject

to

as

little

direct

sound

radiation

as

possible.

B

Do

not

use

or

store

this

unit

where

it

be

exposed

to

dust,

dirt,

high

humidity

high

temperature.

Do

ventilated

location.

@

Do

not

use

under

direct

sunlight,

spotlights,

or

other

ex-

tremely

bright

light

sources.

Bright

lights

may

cause

misopeération

of

the

optical

system

and

therefore

interference

with

automatic

operation.

This

also

applies

to

flashlights

units

brought

very

close

to

the

turntable.

@

Do

not

place

it

near

of

a

power

amplifier,

since

power

amps

radiate

much

heat.

@

Piace

the

turntable

away

to

prevent

hum.

Hum

may

be

caused

by

leakage

flux

from

the

transformer

in

the

power

amplifier

(or

integrated

amp).

Therefore,

if

you

notice

hum,

try

moving

the

turntable

to

a

slightly

different

location,

further

away

from

the

amp.

Replacement

of

stylus

This

unit

is

equipped

with

a

diamond

stylus.

The

replacement

stylus

for

this

cartridge

is

EPS-23CS.

The

life

of

the

stylus

varies

according

to

the

conditions

of

use.

Noise

or

scratchiness

may

indicate

a

worn

or

damaged

stylus.

To

prevent

damage

to

your

records,

the

stylus

should

be

replaced

at

the

first

sign

of

wear.

Therefore,

follow

the

instructions

below.

Note:

Be

sure

you

have

the

amp

volume

knob

turned

down

all

the

way

to

avoid

amplification

of

shock

noise

produced

when

handling

the

stylus.

1.

Open

the

cabinet

gently.

2.

Turn

the

arm

lock

in

the

direction

of

the

arrow

to

lock

the

tonearm.

(Fig.

:

3.

Remove

the

old

stylus

and

push

in

the

new

stylus

assembly

(Fig,

11),

being

careful

not

to

touch

the

stylus

tip.

Be

sure

the

assembly

is

pushed

in

ali

the

way.

4.

Turn

the

arm

lock

back

to

its

original

position.

Replacement

of

cartridge

Although

this

unit

comes

equipped

with

a

high

MM

cartridge

as

standard

equipment,

it

is

also

possible

to

use

any

other

kind

of

plug-in

connector

type

hi-fi

cartridge.

Read

the

instructions

that

came

with

the

new

cartridge.

1.

Open

the

cabinet

gently.

.

2.

Turn

the

arm

lock

in

the

direction

of

the

arrow

to

lock

the

tonearm.

(Fig.

10)

3.

Use

the

screwdriver

to

loosen

the

cartridge

mounting

screw.

(As

shown

in

the

illustration,

loosen

the

screw

until

it

hangs

free.)

(Fig.

M

Auto-return

operation

will

not

function

if

you

press

the

power

switch

while

a

record

is

being

played.

The

tonearm

will

rise

above

the

record

surface

but

étay

where

it

is.

Therefore,

if

you

then

press

the

switchagain

to

the

tonearm

will

go

back

to

the

start

position,

Be

sure

to

remove

all

dirt

and

dust

from

the

stylus

tip

and

the

record.

The

cartridge

stylus

is

an

extremely

delicate

and

precisely

manufactured

device

designed

for

picking

up

the

subtle

nuances

of

the

record

grooves.

Therefore,

be

very

careful

not

to

touch

it,

push

on

it,

or

apply

excessive

force

in

any

way.

The

stylus

tip

cannot

retain

proper

groove

contact

when

it

is

dirty.

This

causes

bad

sound

reproduction

and

excess

wear

on

the

stylus

tip

and

grooves.

Therefore,

use

the

brush

to

remove

dust

and

dirt

by

brushing

upward.(Fig.14)

Also,

use

a

good

record

cleaner

to

remove

dust

and

dirt

from

the

grooves.

Wipe

the

cabinet

with

a

soft,

dry

cloth.

Never

use

volatile

cleaners

such

as

alcohol,

benzine

or

thinner,

Do

not

use

chemically

treated

dust

cloths.

Do

not

expose

the

panel

to

insecticide

spray.

To

remove

stubborn

spots,

first

puil

out

the

AC

plug.

Then

wipe

the

cabinet

with

a

soft

cloth

slightly

moistened

with

a

mild

soap

and

water

solution.

Do

not

wipe

the

upper

cabinet

during

play,

or

the

tonearm

may

be

attracted

toward

the

upper

cabinet

due

to

the

gene-

ration

of

static

electricity.

Open

the

upper

cabinet

gently.

(Fig.

Always

lf

the

the

cannot

properly

and

the

in

the
