Not

the

design

of

is

optimized

for

Tuning

Classified

Memory

Preset

The

memory

presets

are

divided

into

six

classes,

A

through

F,

which

can

be

used

for

different

types

of

programs

(rock,

news,

classical,

etc.).

Or

each

member

of

the

family

can

have

a

separate

class

(class

A

for

Dad,

class

B

for

Mom,

class

D

for

Junior).

Any

preset

station

can

be

assigned

to

any

class.

Direct

Using

Numeric

Buttons

Instead

of

using

the

UP

or

DOWN

tuning

buttons

to

scan

through

the

available

until

the

desired

station

is

located,

Direct

Access

Tuning

lets

you

punch

in

the

broadcast

frequency

directly

using

the

numeric

buttons.

For

example,

103.5

can

be

selected

by

simply

pressing

Care

From

time

to

time

you

should

wipe

off

the

front

and

rear

panels

and

the

cabinet

with

a

soft

cloth.

For

heavier

dirt,

dampen

a

soft

cloth

in

a

weak

solution

of

mild

detergent

and

water

or

a

mild

ammonia

cleaner,

wring

it

out

dry,

and

wipe

off

the

dirt.

Fol-

lowing

this,

dry

immediately

with

a

clean

cloth.

Do

not

use

rough

maternal,

thinners,

alcohol

or

other

chemical

soivents

or

cloths

since

these

could

damage

the

finish

or

remove

Memory

Preservation

This

unit

does

not

require

memory

preservation

batteries.

A

built-in

memory

power

back-up

system

preserves

the

contents

of

the

memory

during

power

failures

and

even

when

the

unit

is

unplugged.

The

unit

must

be

plugged

in

and

the

power

switch

turned

on

and

off

once

in

order

to

charge

the

back-up

system.

Note

that

since

this

is

not

a

permanent

memory,

the

power

switch

must

be

turned

on

and

off

a

few

times

each

month

to

keep

the

back-up

system

operative.

The

memory

preservation

period

after

power

has

been

turned

off

varies

depending

on

climate

and

placement

of

the

unit.

On

the

average,

memory

contents

are

protected

over

a

period

of

a

few

weeks

after

the

last

time

power

has

been

turned

off.

This

period

is

shorter

when

the

unit

is

Connections

Use

the

T-shaped

antenna

if

you

live

in

an

area

where

signal

strength

of

FM

broadcasts

Is

high.

Connect

the

antenna

to

the

and

place

the

antenna

on

a

wall

or

other

surface

in

the

position

in

which

If

your

area,

use

a

multi-element

FM

outdoor

antenna

and

connect

to

this

unit

using

a

75

coaxial

cable

because

this

type

of

cable

is

more

resistant

to

cable.

Consult

your

Onkyo

authorized

service

center

about

the

right

type

of

antenna

for

your

area.

NOTES:

1.

Do

not

connect

both

the

indoor

T-shaped

and

an

If

you

decide

to

install

an

be

sure

to

disconnect

the

indoor

T-shaped

antenna.

Do

not

use

the

antenna

for

both

FM

reception

since

the

FM

and

TV

signals

can

interfere

with

each
