Safety

Precautions

.

The

design

of

this

product

contains

special

hardware

and

many

circuits

and

components

specially

for

safety

purposes.

For

continued

protection,

no

changes

should

be

made

to

the

origina!

design

unless

authorized

in

writing

by

the

manufacturer.

Replacement

parts

must

be

identical

to

those

used

in

the

original

circuits.

Service

should

be

performed

by

qualified

personnel

only.

.

Alterations

of

the

design

or

circuitry

of

the

product

should

not

be

made.

Any

design

alterations

of

the

product

should

not

be

made.

Any

design

alterations

or

additions

will

void

the

manufacturer’s

warranty

and

will

further

relieve

the

manufacturer

or

responsibility

for

personal

injury

or

property

damage

resulting

therefrom.

.

Many

electrical

and

mechanical

parts

in

the

product

have

special

safety-related

characteristics.

These

characteristics

are

often

not

evident

from

visual

inspection

nor

can

the

protection

afforded

by

them

necessarily

be

obtained

by

using

replacement

components

rated

for

higher

voltage,

wattage,

etc.

Replacement

parts

which

have

these

special

safety

characteristics

are

identified

in

the

Parts

List

of

Service

Manual.

Electrical

components

having

such

features

are

identified

by

(A\)

on

the

schematic

diagram

and

Parts

List

in

Service

Manual.

The

use

of

a

substitute

replacement

which

does

not

have

the

same

safety

characteristics

as

the

recommended

replace-

ment

part

shown

in

the

Parts

List

in

Service

Manual

may

create

shock,

fire,

or

other

hazards.

.

The

leads

in

the

products

are

routed

and

dressed

with

ties,

clamps,

tubings,

barriers

and

the

like

to

be

separated

from

live

parts,

high

temperature

parts,

moving

parts

and/or

sharp

edges

for

the

prevention

of

electric

shock

and

fire

hazard.

When

service

is

required,

the

original

lead

routing

and

dress

should

be

observed,

and

it

should

be

confirmed

that

they

have been

returned

to

normal,

after

re-assembling.

.

Leakage

current

check

(Electrical

shock

hazard

testing)

After

re-assembling

the

product,

always

perform

an

isolation

check

on

the

exposed

metal

parts

of

the

product

(antenna

terminals,

knobs,

metal

cabinet,

screw

heads,

headphone

jack,

contro!

shafts,

etc.)

to

be

sure

the

pro-

duct

is

safe

to

operate

without

danger

of

electrical

shock.

Do

not

use

a

during

this

check.

Active

Hyper-Bass

circuit

Generally,

since

low-frequency

sound

is

not

reproduced

satisfactorily

by

small

speakers,

a

bass-boost

circuit

is

used

to

reinforce

low-frequency

sound.

However,

if

the

volume

is

turned

up

with

bass-boost

reinforcement,

low-

frequency

sound

is

easily

saturated

which

results

in

distortion.

As

shown

in

the

diagram,

the

Active

Hyper-

Bass

circuit

incorporates

a

control

circuit

in

which

the

cut-off

frequency

of

low-frequency

sound

is

varied

in

the

bass-boost

circuit,

with

the

cut-off

frequency

controlled

by

instructions

from

a

level

identification

circuit.

With

these

circuits,

when

the

volume

increases,

low-frequencies

are

sharply

attenuated,

which

prevents

distortion

caused

by

the

saturation

of

low

frequencies.
