SAFETY
CHECK-OUT
(US

After
correcting
the
original
service
problem,
perform
the
following
safety
check
before
releasing
the
set
to
the
customer:
Check
the
antenna
terminals,
metal
trim,
‘“‘metallized”
knobs,
screws,
and
all
other
exposed
metal
parts
for
AC
leakage.
Check
leakage
as
described
below.
LEAKAGE
TEST
The
AC
leakage
from
any
exposed
metal
part
to
earth
ground
and
from
all
exposed
metal
parts
to
any
exposed
metal
part
having
a
return
to
chassis,
must
not
exceed
0.5mA
(500

can
be
measured
by
any
one
of
three
methods.

ST-S444ES
FEATURES
PLL-CIRCUIT
EMPLOYING
DIRECT
COMPARATOR
TECHNOLOGY
The
ST-S444ES
with
its
refined
Phase
Locked
Loop
(PLL)
circuit
can
tune
to
a
frequency
with
extraordinary
precision.
An
IC
developed
by
Sony
allows
the
comparison
fre-
quency
to
be
as
high
as
the
50
kHz
channel
spacing
fre-
quency,
thus
eliminating
the
tendency
of
a
low
com-
parison
frequency,
which
was
formerly
generally
em-
ployed,
to
slip
into
the
audio
range
and
degrade
the
signal-to-noise
ratio.
The
local
oscillator
output
can
therefore
be
directly
supplied
to
the
programmable
divider
section
without
an
additional
pre-scaler.
We
call
this
PLL-circuit
technology
the
Direct
Comparator
meth-
od.
The
result
is
almost
rippleless
local
oscillation,
greatly
reduced
spurious
radiation,
and
an
extremely
high
signal-to-noise
ratio.
STATE
OF
THE
ART
Every
element
of
the
ST-S444ES
is
chosen
with
an
eye
to
optimum
reception.
Dual-gate
MOS
FETs
in
the
RF
amplifier,
and
five
varactors
in
the
front-end
block
in-
sure
high
sensitivity
and
an
excellent
spurious
response
ratio.
Four
uni-phase
filters
in
the
IF
amplifier
provide
high
selectivity.
The
PLL
multiplex
decoder
with
a
pilot
canceler
insures
a
flat
frequency
response,
clear
sepa-
ration
and
very
low
distortion.
EFFORTLESS
TUNING
Tuning
is
easy
using
the
digital
frequency
readout
in
the
frequency
display
window.
Three
methods
of
tuning
are
available
:
Automatic
tuning,
in
which
the
entire
AM
or
FM
band
is
scanned
automatically
until
a
signal
is
received.
Manual
tuning,
in
which
the
AM
or
FM
band
can
be
scanned
either
rapidly
or
step-by-step.
Memory
preset
tuning,
in
which
the
frequencies
of
up
to
eight
stations
can
be
stored.
In
this
mode,
this
infor-
mation
will
be
retained
when
the
power
is
turned
off
so
that
you
can
tune
in
your
favorite
station
with
the
push
of
a
button.
Various
conditions
can
also
be
memorized
for
each
individual
station
to
permit
one-touch
reception.
All
the
memorized
settings
are
displayed
in
the
FL
display
window.
The
SCAN/READ
button
allows
you
to
scan
automa-
tically
the
preset
stations
only,
listening
to
each
one
for
a
few
seconds
to
check
if
there
is
anything
you
would
like
to
listen
to.

A.C.T.
(AUDIO
CURRENT
TRANSFER)
CIRCUIT
This
tuner
employs
the
A.C.T.
technique
developed
for
Sony
integrated
amplifiers.
The
A.C.T.
circuit
design
vir-
tually
eliminates
the
problems
which
the
conventional
voltage
transfer
design
had:
electrical
interference
be-
tween
the
left
and
right
channels,
decreased
sound
quality,
distortion,
noise,
etc.
caused
by
the
fact
that
both
the
signal
source
current
and
the
power
supply
cur-
rent
flow
through
the
same
ground.
This
technique
insures
the
tuner’s
high-quality
recep-
tion
performance.
PROGRAM
FUNCTION
Using
the
Program
Function,
you
can
automatically
tune
in
to
up
to
four
stations
which
have
been
memoriz-
ed
in
any
sequence
you
want.
Stations
will
be
received
one
by
one
as
the
power
is
turned
on
and
off
by
an
op-
tional
timer.
This
Program
Function
enables
timer-
activated
reception
or
recording
of
a
number
of
stations
as
compared
to
the
single
station
capability
of
conven-
tional
tuners.
OTHER
REFINEMENTS
The
HI-BLEND
switch
reduces
noise
in
FM
stereo
rece-
tion.
The
ten-step
SIGNAL
indicator
shows
the
strength
of
the
tuned
signal.
The

signal
(equivalent
to
37.5
kHz
deviation),
which
is
useful
for
calibrating
the
recording
level
on
a
tape
deck.
The
two-pole
beat-cut
filter
is
positioned
before
the
multi-
plex
circuit
to
assure
better
FM
stereo
reception.
OPERATING

Before
connecting
the
unit
to
the

PRECAUTIONS
On
safety
eBefore
operating
the
unit,
be
sure
that
the
operating
voltage
of
your
unit
is
identical
with
that
of
your
local
power
supply.
eShould
any
liquid
or
soild
object
fall
into
the
cabinet,
unplug
the
unit
and
have
it
checked
by
qualified
person-
nel
before
operating
it
any
further.
e
Unplug
the
unit
from
the
wall
outlet
if it
is
not
to
be
used
for
an
extended
period
of
time.
To
disconnect
the
cord,
pull
it
out
by
grasping
the
plug.
Never
pull
it
out
by
the
cord.
On
installation
eDo
not
install
the
unit
in
a
location
near
heat
sources
such
as
radiators
or
air
ducts,
or
in
a
place
subject
to
direct
sunlight,
excessive
dust,
mechanical
vibration
or
shock.
eGood
air
circulation
is
essential
to
prevent
internal
heat
build-up
in
the
unit.
Place
the
unit
in
a
location
with
adequate
air
circulation.
On
operation
eWhen
the
unit
is
not
in
use,
turn
the
power
off
to
con-
serve
energy
and
to
extend
the
useful
life
of
your
unit.
eSet
the
PROGRAM
switch
to
OFF
when
the
Program
Function
is
not
being
used.
If
this
is
not
done,
you
can-
not
tune
with
the
TUNING
or
station
preset
buttons.
On
cleaning
Clean
the
cabinet,
front
and
rear
panels
periodically
with
a
soft
dry
cloth.
If
the
stains
are
difficult
to
remove,
use
a
cloth
moistened
with
a
mild
detergent
solution.
Do
not
use
solvents
such
as
alcohol,
benzine
or
thinner,
since
they
will
damage
the
finish.
On
repacking
Do
not
throw
away
the
carton
and
the
packing
material.
It
makes
an
ideal
container
to
transport
the
unit
in.
When
shipping
the
unit
for
repair
work
or
to
another
location,
repack
it
as
illustrated
on
the
carton
box.
