SAFEGUARD

Electrical

energy

can

perform

many

useful

functions.

This

unit

has

been

engineered

and

manufac-

tured

to

assure

your

personal

safety.

Improper

use

can

result

in

potential

electrical

shock

or

fire

hazards.

In

order

not

to

defeat

the

safeguards,

observe

the

following

instructions

for

its

installation,

|

use

and

servicing.

WARNING:

TO

PREVENT

FIRE

OR

SHOCK

HAZARD,

DO

NOT

EXPOSE

THIS

APPLIANCE

TO

RAIN

OR

MOISTURE.

Notice:

The

switch

is

secondarily

connected

and

does

not

separate

the

apparatus

from

the

net

in

the

switched-off

position.

As

to

the

INSTALLATION

When

installing

the

FT-5500

choose

a

place

that

satisfies

the

following

conditions:

1.

Install

it

in

a

place

out

of

direct

sunlight

and

away

from

stoves,

etc.

2.

install

it

in

a

place

where

ventilation

is

good

and

which

is

free

from

moisture

and

dust.

3.

Install

the

tuner

on

a

stable

and

vibration-free

surface.

1.

Placement

on

an

ordinary

shelf

Leave

a

clearance

of

at

least

4

cm

be-

tween

the

units.

NOTE:

Leave

a

clearance

of

at

least

4

cm

between

this

unit

and

the

amplifier

when

the

amplifier

you

are

using

has

a

high

power

output

or

when

the

amplifier

is

being

used

at

a

high

(Installation

NOTE:

Do

not

install

your

amplifier

in

the

audio

rack

(see

Fig.

2)

if

the

amplifier

you

are

using

has

a

high

power

output,

the

amplifier

is

being

used

at

a

high

power

output

level

or

if

your

audio

rack

is

enclosed

and

poorly

ventilated.

This

is

to

reduce

the

effects

of

heat

generated

by

the

amplifier

on

the

unit.

if

the

amplifier

is

to

be

installed

in

the

audio

rack,

make

sure

that

there

is

sufficient

space

(see

Fig.

3)

for

the

heat

generated

by

the

amplifier

to

dissipate

freely.

This

will

then

reduce

the

effects

of

the

heat

generated

on

the

unit.

IMPORTANT

FOR

U.K:.:

The

wires

in

this

mains

lead

are

coloured

in

accordance

with

the

following

code:

Blue:

NEUTRAL

Brown:

LIVE

As

the

colours

of

the

wires

in

the

mains

lead

of

this

apparatus

may

not

correspond

with

the

coloured

markings

identifying

the

terminals

in

your

plug

proceed

as

follows:

The

wire

which

is

coloured

BLUE

must

be

connected

to

the

terminal

which

is

marked

with

the

letter

N

or

coloured

BLACK.

The

wire

which

is

coloured

BROWN

must

be

connected

to

the

terminal

which

is

marked

with

the

let-

ter

L

or

coloured

RED.

1.

New

field

condition

computer

system

(FCCS)

technique

The

microcomputer

first

conducts

a

search

to

see

if

there

are

any

broadcasting

stations

generating

in-

terference

with

the

desired

station.

If

there

is

no

interference,

it

switches

to

high-sensitivity

reception;

if

there

is

some

interference,

the

selectivity

of

the

RF

or

IF

stage

is

automatically

enhanced

and

reception

permitted

with

reduced

interference.

In

short,

this

unit

features

a

optimum

reception

system

which

in

HITACHI's

language

is

known

as

a

field

condition

computer

system.

Moreover,

the

results

of

the

com-

puter

search

are

automatically

preset

and

memorized

for

instant

recall

of

the

optimum

reception

mode

at

any

time.

2.

The

AM/FM

tuning

circuits

adopt

a

digital

synthesizer

system

which

is

based

on

a

crystal

oscillator

and

a

PLL

(Phase-Locked-Loop)

in

order

to

keep

the

deviations

in

the

local

oscillation

frequency

down

to

the

accuracy

of

the

crystal

oscillator.

The

adoption

of

a

microcomputer

for

the

tuning

control

permits

automatic

tuning

from

87.9

*(87.50)

MHz

to

107.9

*(108.00)

MHz

in

100*

(50)

kHz

steps

for

FM

recep-

tion

and

manual

tuning

from

530

*(522)

kHz

to

1,620

*(1,611)

kHz

for

AM

reception.

The

preset

system

is

based

on

random

access

principles

and

the

total

number

of

stations

which

can

be

preset

is

10

in-

cluding

both

AM

and

FM.

It

serves

to

provide

more

accurate

tuning

and

enhance

operating

ease

—

ideal

features

now

that

the

number

of

broadcasting

stations

is

on

the

rise.

Newly

developed

S.B.

(Station

Brightener)

MPX

IC

This

unit

features

the

new

HA12031

SB

MPX

IC

which

is

designed

to

eliminate

the

beat

(birdy)

noise

generated

during

FM

stereo

reception

by

interference

from

broadcasting

stations

adjacent

to

the

one

tuned

in,

without

impairing

the

stereo

separation.

4.

While

the

field

condition

computer

system

is

operating,

the

signal

strength

meter

switches

over

to

display

the

frequency

so

that

the

computer

search

can

be

indicated

in

visual

form

and

the

computer

search

movement

is

shown

by

an

LED

pointer.

5.

High

sensitivity

with

large-sized

loop

antenna

Stations

come

in

loud

and

clear

thanks

to

the

new

AM

RF

circuit

and

large-sized

loop

antenna

with

the

high

gain

that

is

immune

from

noise

and

interference.

The

loop

antenna

can

be

detached

from

the

unit

and

installed

in

a

position

which

yields

optimum

reception.

6.

Keyboard

switches

with

preset

indicators

The

fingertip

controlled

keyboard

switches

come

with

preset

indicators.

These

light

up

to

indicate

which

preset

station

(1

through

10)

is

being

tuned

in

during

preset

tuning.

7.

4-element

ladder

type

of

AM

ceramic

filter

Another

prime

feature

of

this

unit

is

the

4-element

ladder

type

of

AM

ceramic

filter

that

gives

you

fun

with

AM

reception

without

ail

that

annoying

interference

and

noise

but

with

a

superb

sound

quality.

8.

The

FT-5500

has

a

convenient

memory

back-up

system

for

protecting

the

memory

contents

when

the

power

is

OFF.

9.

The

FT-5500

is

also

equipped

with

a

recording

level

check

mechanism

which

is

very

handy

for

FM

pro-

gram

recording.

This

provides

a

440

reference

signal

and

is

used

to

set

the

recording

level

to

the

op-

timum

ANTENNAS

antenna

connections

FM

broadcasts

are

characterized

best

by

their

good

sound

quality.

To

enjoy

sound

with

a

good

quality,

it

is

important

to

pick

up

the

signals

reliably.

Just

like

TV

signals,

FM

broadcast

signals

use

ultra-short

waves

and

they

are

beamed

directly,

rather

like

light.

This

means

that

the

signal

strength

will

weaken

in

mountainous

areas

and

between

high

buildings.

Choose

the

proper

antenna

in

accordance

with

the

strength

of

the

signals

in

your

area.

Using

the

accessory

FM

feeder

The

feeder

antenna

will

sufficiently

serve

for

reception

when

the

unit

is

are

in

such

erect
