TIPS

ON

RECORD

HANDLING

e@

Before

playing,

clean

the

record

with

a

record

cleaner

or

soft

cloth.

If

a

spray

cleaner

is

used,

make

sure

that

it

has

dried

com-

pletely

before

playing

the

record.

Playing

the

record

before

the

cleaner

has

dried

may

damage

the

record.

It

is

a

good

idea

to

clean

the

record

again

before

putting

it

away.

@

Handle

a

record

by

its

edges

and

do

not

touch

the

grooves.

Fingerprints

on

the

record

surface

may

encourage

an

accumula-

tion

of

dust,

resulting

in

impaired

tone.

@Use

a

commercially

available

anti-static

spray

to

neutralize

the

static

electricity

on

a

record.

@Avoid

exposing

a

record

to

direct

sunlight

or

sources

of

heat,

such

as

a

hot-air

duct.

@Store

your

records

vertically.

MAINTENANCE

Stylus

Before

playing

a

record,

clean

the

stylus

with

a

soft

brush.

Brush

the

stylus

from

back

to

front.

Never

attempt

to

clean

the

stylus

with

your

finger

tip.

If

a

fluid

stylus

cleaner

is

used,

make

sure

not

to

moisten

the

stylus

too

much.

Cabinet

Clean

the

cabinet

and

dust

cover

periodically

with

a

soft

dry

cloth.

If

the

stains

are

difficult

to

remove,

use

a

cloth

moistened

with

a

mild

detergent

solution.

Do

not

use

solvents

such

as

alcohol,

ben-

zine

or

thinner,

since

they

will

damage

the

Lubrication

The

turntable

requires

no

periodic

lubrication.

The

motor

shaft

is

lubricated

at

the

factory

for

the

life

of
