3.

Connect

the

left

and

right

Output

jacks

on

the

deck

to

the

"Tape

Input"

jacks

(often

labeled

"Play"

or

"Monitor")

on

your

receiver/pre-amp/integrated

amplifier.

NOTE:

/f

you

are

using

an

equalizer

and/or

other

external

signal

processing

components,

which

are

now

connected

to

the

Tape

Monitor

loop

of

your

receiver/pre-amp/integrated

amplifier,

you

have

two

choices:

a.

Connect

the

deck

to

the

Tape

Monitor

loop

provided

on

the

last

outboard

component;

or

b.

If

your

receiver/pre-amp/iritegrated

amplifier

has

two

Tape

Monitor

loops,

you

may

connect

the

cassette

deck

to

the

unused

loop.

(In

this

case,

the

cassette

deck

will

be

unaffected

by

the

external

signal

processing

components.)

the

cord

into

a

socket,

polarized

cord,

or

Remote

Control

if

you

wish

to

control

your

deck

with

an

external

infrared

remote

control

sensor,

connect

the

wire

from

the

remote

sensor

to

your

cassette

deck’s

"Remote

Input"

jack.

(A

control

wire

may

then

be

run

from

the

deck’s

"Remote

Output"

jack

to

the

"Remote

Input"

of

another

stereo

component.)

Alternatively,

if

you

have

a

stereo

component

with

a

built-in

infrared

remote

sensor

and

a

"Remote

Output"

jack,

it

may

be

possible

to

connect

this

jack

to

the

"Remote

input"

jack

of

your

cassette

deck.

Not

all

components

are

compatible,

but

it

will

not

hurt

to

experiment.

Once

your

deck

is

connected,

you

will

need

a

compatible

remote

control

commander.

One

such

commander

is

the

remote

control

unit

from

Harman

Kardon’s

TD450

cassette

deck,

available

through

Harman

Kardon’s

Parts

Department.

In

addition,

most

Harman

Kardon

Receivers

include

a

System

Remote

Control

which

will

control

the

functions

of

the

cassette

deck.

Cleaning

the

Tape

Heads

Tape

heads

must

be

cleaned

periodically

to

remove

tape

particles,

which

gradually

build

up

on

the

heads,

impairing

sound

quality

and

increasing

wear

on

tapes.

Heads

may

be

cleaned

in

either

of

two

ways:

1.

Slightly

dampen

a

cotton

swab

in

isopropyl

alcohol

and

gently

rub

the

-Surfaces

of

each

tape

head.

Use

a

second

dampened

swab

to

clean

other

surfaces

coated

with

tape

material.

Repeat

this

cleaning

every

30

tapes.

The

TD420

is

equipped

with

an

access

hole

on

the

top

of

the

unit

to

facilitate

cleaning

of

the

heads.

Be

careful

not

to

lose

the

cover

to

this

access

hole.

2.

Use

a

tape

head

cleaning

kit,

which

comes

in

the

form

of

a

tape

cassette,

and

is

simply

inserted

into

the

deck.

Follow

the

instructions

included

with

the

kit.

Demagnetization

Tape

heads

and

other

internal

parts

gradually

pick

up

magnetic

fields,

which

can

add

noise

to

your

tapes

and

even

partially

erase

them.

To

prevent

this

problem,

tape

heads

should

be

periodically

demagnetized.

A

battery-powered

demagnetizer

is

easiest

to

use.

It

comes

in

the

form

of

a

tape

cassette

and

is

simply

inserted

into

the

deck.

Be

certain

to

use

this

demagnetizer

as

frequently

as

its

instructions

recommend.

Care

of

Tape

1.

Store

cassettes

in

their

cases,

in

a

location

away

from

direct

sunlight,

excessive

heat

and

high

humidity.

2.

Avoid

placing

a

tape

near

a

television

set

or

loudspeaker;

their

magnetic

fields

can

partially

erase

the

tape.

3.

To

prevent

accidental

erasure

of

a

tape,

use

a

small

screwdriver

to

remove

the

two

square

tabs

located

—

on

the

side

of

the

cassette

opposite

the

exposed

tape.

With

these

tabs

removed,

the

tape

cannot

be

recorded.

If

you

later

wish

to

record

an

erasure-protected

tape,

simply

cover

the

smail

holes

with

adhesive

tape.

4.

Do

not

use

old

cassettes

whose

tape

no

longer

moves

smoothly

from

reel

to

reel.

They

may

jam

and

damage

your

deck.
