as long as is reasonably practical. It must be kept away from large metal objects, power lines or electrical machinery to insure reception without extraneous noise. Attach external antenna to rear terminal strip marked "AM." The loopstick antenna may be swiveled as required for custom and bookshelf installation. If the metal cage is used, the loopstick should be moved down and away from the cage to prevent cancellation of the AM signals. FM Antenna: Due to the exceptionally high FM sensitivity of the ST350, the 48" piece of wire supplied with the tuner will be sufficient antenna for all but the most difficult locations. One end of this wire should be stripped of insulation and attached to the rear screw terminal marked "FM" on the Antenna Terminal Strip located on the rear of the ST350 chassis. The other end of the wire should be extended horizontally along the cabinet or table. Horizontal placement of the antenna wire offers maximum polarization for optimum reception. If an outdoor antenna is required to "reach" for distant stations use a special folded dipole or Yagi cut specifically for the FM band. A homemade 300 ohm "T" type antenna is not entirely satisfactory and should not be used as a substitute for the 48" piece of wire supplied with the tuner. The "T" type antenna has a tendency to pick up extraneous noise. TV antennas are rarely satisfactory as they are not cut for the FM band and have a tendency to introduce ignition noise into the tuner. They are not recommended except under unavoidable circumstances. Usually better results can be obtained with the 48" piece of wire. When using an outdoor antenna, attach the 300 ohm lead-in wire (twisting it 4-5 times for each running foot) to the antenna terminals on the rear of the ST350 marked FM and G. Grounding: It is not generally recommended to separately ground the ST350 tuner to your companion amplifier. This may cause a ground loop and induce hum. OPERATING INSTRUCTIONS Front Panel Controls: The ST350 incorporates the following operating controls located on the front panel. Viewing the tuner from left to right you will note the AM TUNING control, PUSH BUTTON FUNCTION SWITCH (AM Noise Filter, AM, Stereo AMFM, Stereo Multiplex, FM, FM-AFC, Power Off), and FM Tuning control. To Receive Monophonic AM Broadcasts: Depress the AM push button to turn the tuner on and to select the AM broadcast band. Tune to the desired station with the AM TUNING control. To insure proper tuning a unique electronic eye tuning indicator has been incorporated into the AM circuit. Tune for minimum dark space between the green bars. To receive noisy or distant AM stations depress the AM NOISE FILTER push button. A special electronic filter will eliminate the interference that generally accompanies long range AM reception.

as
is

practical.
It
must
be
kept
away
from
large
metal
objects,
power
lines
or
electrical
machinery
to
insure
reception
without
extraneous
noise.
Attach
external
antenna
to
rear
terminal
strip
marked
"AM."
The
loopstick
an-
tenna
may
be
swiveled
as
required
for
custom

installation.
If
the
metal
cage
is
used,
the
loopstick
should
be
moved
down
and
away
from
the
cage
to
prevent
cancellation
of
the
AM
signals.
FM
Antenna:
Due
to
the
exceptionally
high
FM
sensitivity
of
the
ST350,
the
48"
piece
of
wire
supplied
with
the
tuner
will
be
sufficient
antenna
for
all
but
the
most
difficult
locations.
One
end
of
this
wire
should
be
stripped
of
insulation
and
attached
to
the
rear
screw
terminal
marked
"FM"
on
the
Antenna
Terminal
Strip
located
on
the
rear
of
the
ST350
chassis.
The
other
end
of
the
wire
should
be
extended
hor-
izontally
along
the
cabinet
or
table.
Horizontal
placement
of
the
antenna
wire
offers
maximum
polarization
for
optimum
reception.
If
an
outdoor
antenna
is
required
to
"reach"
for
distant
stations
use
a
special
folded
dipole
or
Yagi
cut
specifically
for
the
FM
band.
A
homemade
300
ohm
"T"
type
antenna
is
not
entirely
satisfactory
and
should
not
be
used
as
a
substi-
tute
for
the
48"
piece
of
wire
supplied
with
the
tuner.
The
"T"
type
antenna
has
a
tendency
to
pick
up
extraneous
noise.
TV
antennas
are
rarely
satisfactory
as
they
are
not
cut
for
the
FM
band
and
have
a
tendency
to
introduce
ignition
noise
into
the
tuner.
They
are
not
recom-
mended
except
under
unavoidable
circumstances.
Usually
better
results
can
be
obtained
with
the
48"
piece
of
wire.
When
using
an
outdoor
antenna,
attach
the
300
ohm
lead-in
wire
(twisting
it
4-5
times
for
each
running
foot)
to
the
antenna
terminals
on
the
rear
of
the
ST350
marked
FM
and
G.
Grounding:
It
is
not
generally
recommended
to
separately
ground
the
ST350
tuner
to
your
companion
amplifier.
This
may
cause
a
ground
loop
and
induce
hum.
