choosing

a

Harman

Kardon

compact

disc

player.

This

is

a

superb

piece

of

high

fidelity

equipment

that

has

been

meticulously

designed

to

provide

you

with

thousands

of

hours

of

enjoyment.

The

HD7225

use

Harman

Kardon’s

3D

Bit

Stream

technology

for

conversion

of

the

digital

signal

to

analog.

The

HD7425

uses

Harman

Kardon’s

exclusive

RLS

(Real-time

Linear

Smoothing)

system.

RLS

results

in

improved

imaging

and

a

smoother,

more

natural

sound from

your

compact

discs.

To

appreciate

the

full

performance

of

this

sophisticated

unit,

please

be

sure

to

read

this

owncr’s

Placement

This

unil

is

fully

shielded

and

may

be

placed

on

top

of

or

under

other

stereo

components

as

long

as

the

“feet”

provide

sufficient

clearance

for

cooling

of

the

component

below.

Please

make

sure

that

the

unit

receives

adequate

ventilation.

It

should

always

be

located

away

from

heat

sources

such

as

radiators,

fireplaces,

stoves,

and

other

appliances

that

produce

heat.

Avoid

placing

the

unit

in

locations

that

receive

prolonged

direct

sunlight

or

extremnely

low

temperatures.

While

your

compact

disc

player

is

designed

to

be

vibration-resistant,

excessive

shocks

or

placement

too

close

to

large

speakers

can

cause

“stuttering”

or

skipping.

When

choosing

a

place

for

your

new

CD

player,

take

the

same

precautions

you

would

with

a

turntable.

Care

of

the

laser

pickup

The

laser

pickup

that

detects

the

music

recorded

on

a

CD

is

located

under

the

compact

disc

drawer.

The

laser

pickup,

especially

its

precision

lens,

is

particularly

sensitive

to

dust.

Keep

the

disc

drawer

closed

when

the

unit

is

not

in

use,

and

do

not

put

your

hand

inside

the

unit.

Interference

‘This

compact

disc

player

uses

high-frequency

signals

that

can

sometimes

interfere

with

reception

in

tuners

and

televisions.

If

you

start

to

experience

reception

problems

after

comnecting

and

turning

on

your

CD

player,

move

the

CD

player

farther

away

from

your

tuner

or

television

set

or

turn

the

CD

player

off

when

it

is

not

in

use.

Always

use

the

correct

AC

voltage

Always

connect

the

power

cord

to

a

domestic

mains

outlet.

Never

connect

the

unit

to

an

outlet

supplying

a

higher

voltage.

This

may

create

a

fire

hazard.

Hints

As

carefully

connect

the

plugs

to

the

output

jacks,

being

sure

to

push

the

plugs

in

all

the

way.

Loose

connection

of

can

cause

Take

to

on

CD

player

with

the

left

Common

practice

is

to

use

the

red

plug

as

right,

and

the

white,

gray,

or

black

plug

as

left.

Do

not

wind

the

doing

so

may

degrade

the

When

you

have

finished

connecting

plug

the

power

either

into

To

load

batteries

1.

Locate

the

compartment

on

the

Remove

the

cover

by

sliding

it

in

the

direction

of

the

arrow.

2.

Insert

the

two

AA

(1.5V/R6/UM3)

batteries.

Make

sure

you

insert

the

batteries

according

to

the

+

and

—

polarity

symbols

at

the

bottom

of

the

battery

compartment.

3.

Replace

the

cover

of

the

compartment.

When

you

replace

weak

batteries,

replace

both

at

the

same

time.

The

remote

control

operates

within

a

30”

angle

of

the

remote

Make

sure

that

the

“ens”

as

well

as

the

REMOTE

SENSOR

area

on

the

front

panel

of

the

unit

are

kept

free

from

dirt

to

cnsure

proper

transmission

and

reception

of

the

infrared

beam.

Also

make

sure

that

no

objects

(e.g.,

stereo

cabinet

doors,

end

tables)

block

the

path

from

the

remote

control

to

the

REMOTE

SENSOR

area.

Avoid

using

the

remote

control

near

fluorescent

lamps,

as

they

may

shorten

its

operating

range.

If

your

remote

control

will

sit

unused

for

a

long

period

of

time,

remove

the

batteries

to

prevent

damage

from

corrosion.
