RECORD

AND

STYLUS (NEEDLE)

CARE

Keep

Clean

-Proper

care

of your records and

phono-

graph stylus will

provide many

hours

of trouble-free

operation.

Avoid the use of

record-cleaning

sprays.

Keep

records free

of

dust

by

storing

in their

jackets when not

in

use.

For best

results,

clean the stylus weekly with

a

suitable

stylus

cleaner*

or high purity

isopropyl

alcohol

on

a

small

stylus

cleaning brush*

or a small

artist's-type brush.

Check

for Wear

-

Check the

stylus for

wear every lOO

operating

hours or

less

with

a stylus microscope*

The stylus

shouid

be replaced after

approximately 400

operating

hours.

As

the stylus wears, flat spots

on the stylus

will

tend to

remove

the high frequencies from

your records.

Once

destroyed,

these high

frequencies

are

permanently

lost

from

the

records

and

will

cause noticeable

loss

of fidelity.

A

worn stylus

should

be replaced

for best

stereo

performance

and for

prolonging the

life

of your

records.

REPLACING

THE STYLUS (See Figure

10)

Lift the

Tone

Arm and

grasp the

stylus

assembly.

Pull

it

straight

out

of

the

as shown in

the illustration,

To in-

stall

a new stylus,

insert

it

back into the cartridge

firmly,

Replacement

MAINTENANCE

TAPE UNIT CLEANING

(Refer to

Figure

15)

During

normal

operation,

oxide particles are loosened

from

the tape and

build up on the Tape Head, the Automatic

Program Selector Switch, Tape Guide, and

the Capstan. This

tape unit must

be cleaned at regular intervals

(at

least

every lO

operating

hours) since

this oxide accumulation will

cause poor

sound quality and

possibly

affect the operation

of the unit.

Clean

as

follows:

I Remove the

tape cartridge from

the

tape

slot.

2. While holding

the Tape Door

open, look at the

inside of

your

tape

unit.

Locate

the

motor Switch (See Fig.

15).

This

switch

may

be

in any of the four positions shown in Fig.

15,

labeled

A,B,C or D.

3. Turn main unit on

by

moving the POWER Switch

(See

Fig.

1)

to

the ON

position.

Depress the Motor Switch (in

17

location A, B,

C or D) with the

eraser

end of a pencil. This

causes the

capstan to rotate.

4

Clean the

capstan

(while

rotating),

the

Automatic

Program

Selector Switch,

the

Tape

Head

and the Tape

Guide

with

Zenith Tape

Head

Cleaner

(Part No.

929-126

or 929-129).

Specific

directions

come with these

cleaners,

5.

Allow

unit to dry

before

using

again.

NOTE;

if Zenith Tape

Head Cleaner

is not

available,

use a

cotton

swab (Zenith Part

No. 929-128)

dampened

in high

purity

isopropyl

alcohol,

CAUTION: Do

not

use other

commercial tape

head

cleaners

or cleaning cartridges,

as they

may react

unfavorably

with

the

material

used in the manufacture

of the

tape head.

Do

not

clean

the head with

any sharp or metal

object. Do not

use

a brush with

a metal

band around the

bristles.

Do not

allow any

cleaning

materials to fall into

the tape

assembly.

TAPE

HEAD

DEMAGNETIZING

The

Tape

Head, after

a long

period of

time,

will acquire

some magnetism.

A Tape Head

that

is magnetized

will show

a

definite loss

of high

frequency

response

and an increase

in noise

level.

Use any commercially

available head

demagnetizer,

following

the instructions

included

with the

unit to

demagnetize

the

head.
