(PowER)

When

this switch

is

set

to the ON

position,

power

is supplied

to the

tuner's main circuits.

The unit's

power

switch

is

geared

to selecting

the transformer's secondary

and so even

at

the

STAND-BY

position,

the unit's circuitry

will work as

long

as

the

power

cord

is connected

to the

power

outlet.

Disconnect

the

power

cord

from the AC

power

outlet when

the

unit

is not

in

regular

use.

@

This indicates that

an

received.

@

MUTING)

In the

released

position

when

it is

normally set,

this switch

suppresses

the annoying

interstation

noise

which

is heard

when tuning

in FM

broadcasting stations.

lf the station

signals are

weak

and

there is a

great

deal of

noise

and

distortion,

depress

this switch

(and

monaural

sound

reproduction

results).

This switch

does

not work

with MW and

LW

reception.

ANTENNA

(accessory)

This antenna

and

it

should

be

connected

to the rear

panel

of the unit.

This

is

a

spare antenna

for

listening to FM stations and

is

used until

an outdoor

is erected.

For the best

reception,

an

outdoor antenna

should

be obtained.

AND

ANTENNA

cATcHER

(accessory)

This antenna

is for

listening

to

MW and

it

should be connected

to the rear

panel

of the unit.

The

anten-

na

catcher

is used

when fixing

the

antenna

to

a

wall or other

location.

NOTE:

Even with

the accessory

T-type FM antenna

and AM antenna

it

may be impossible

to tune into some

stations

when the broad-

cast

stations

are

too far awaY or

when the unit

is

located in a

weak-signal

area such

as in the mountains.

ln cases

like this, use

an external

antenna.

Tuner

The

(2SK168)

single-stage

RF amplifier,

and

NPN

transistor

mixer,

and

an

of.

2 dual-element

and

IF

(PA3001-A)

which

incorporates

the

IF limiter

amplifier, FM

detector,

ffid

the

circuit.

FM Multiplex

Stereo

Decoder

The

stereo

decoder

stage employs

an

FM

MPX

IC

(HA1L56W-P),

while

the

subcarrier

signals

(frequencies

above

19kHz)

are

removed

by an

-

18dB/oct.

active filter

consisting

of a PNP

tran-

sistor. This

active filter

also serves

as an

amplifier

for

frequencies

within its

passband,

and

eliminates

crosstalk.

AM

Tuner

The

AM

tuner is two

wave-band tuner

$rith LW

(150kHz-350kHz)

and MW

(525kHz-1605kH2).

This employs

a

2-ganged

tuning capacitor,

a single

element ceramic filter,

and an IC

(HA1138)

consisting

of an

RF

amplifier, mixer,

2-stage IF

amplifier,

detector and AGC

circuit.
