INTRODUCTION:

"Linear

Drive",

a

novel

engineering

approach

to

the

difficult

task

of

rotating

a

turntable

accurately

and

without

undesirable

drift

is

featured

in

this

unit.

This

drive

employs

120

magnetic

poles

instead

of

the

usual

4

to

24.

It

achieves

a

completely

uniform

rotation

and

virtually

eliminates

wow

and

flutter

as

well

as

rumble.

IMPORTANT

.

..

This

highly

sophisticated

turntable

was

developed

by

FISHER

to

give

you

many

years

of

listening

enjoyment.

Please

read

the

following

instructions

carefully.

They

were

prepared

to

assist

you

during

the

initial

set-up

and

to

ensure

ultimate

performance

of

the

turntable

at

all

times.

THE

WARRANTY

MAINTENANCE

Remember

that

your

turntable

is

a

sensitive

electro¬

mechanical

device

that

needs

occasional

maintenance.

Cleaning

the

stylus:

Dust

particles

often

build

up

around

the

stylus.

If

the

build-up

becomes

excessive

it

will

not

only

result

in

noisy

repro¬

duction

but

will

eventually

shorten

the

lives

of

both

the

record

and

the

stylus.

Should

this

occur,

do

not

remove

the

dust

with

your

fingers

or

a

tool.

Lift

the

tone

arm

by

its

handle

and

blow

the

dust

away

or

use

a

stylus

brush.

Replacing

the

stylus:

To

assure

distortion-free

reproduction,

replace

the

diamond

stylus

after

1000/2000

LP

plays.

To

remove

the

old

stylus,

pull

out

the

stylus

assembly

as

in

Fig.

9.

Replace

with

a

new

stylus

(available

from

Fisher

Service

Center).

3

Cleaning

the

dust

cover,

cabinet

and

visible

metal

parts:

Wipe

gently

with

a

soft

cloth

moistened

with

lukewarm

water.

NEVER

use

benzol,

benzine

or

other

strong

chemical

cleaners

since

they

will

damage

the

finish

of

your

unit.

DO

NOT

allow

moisture

to

penetrate

inside

of

the

turntable.
