Am/fm stereo tuner

will automatically determine whether your
unit
is receiving
monophonic
or stereo-
phonic broadcasts, and then automatically
adjust the mode of operation. If the station
is transmitting stereo, your tuner will auto-
matically switch
on the multiplex
section
and you
will hear the broadcast in full
stereo. Should the station conclude broad-
Casting
in stereo,
your
tuner
will
auto-
matically
switch
back
to
monophonic
reception.
2. STEREO
ONLY
Should
you wish to pick up only stereo
stations, set the function selector control to
the STEREO
ONLY
position.
A special
circuit is automatically set for you to tune
In only stereophonic broadcasts discarding
monophonic.
3. FM MONO
Should you wish to receive monophonic
signal, or weak stereo signal whose quality
has been degraded by noise and poor signal
conditions and so may be necessary to be
heard
in mono, turn the function selector
control to FM MONO.
Tune
for the
desired
station
with
the
tuning knob, using the tuning meters to
assure the strongest possible reception.
4. AM
Should you wish to listen to AM broad-
casts, turn the function selector control to
AM. Though
AM gives only monophonic
signal, the tuner will convert the signal to
SPECIFICATIONS
two channels enabling you to listen from
two speakers as in stereo.

MUTING
Whenever you tune for an FM station, you
will hear rather loud interstation noise; this
is normal for all highly sensitive FM tuners
and is not peculiar to this tuner.
To
reduce
this
bothersome
interstation
noise, your tuner is equipped with a unique
MUTING LEVEL CONTROL.
Muting
can
be effected
by turning the
control
to either
10uV or 304V
position
to suit your need. If you wish to tune ina
relatively weak signal, set the control at 10
uV so that muting will not suppress all the
weak signals. For tuning in strong stations,
the control may be set at 304V.
The MUTING
LEVEL
CONTROL
should
normally
be turned
OFF
when
you
have
tuned in the desired station, but it may be
left at either on position without causing
perceptable effect upon program reproduc-
tion. However, if you have tuned in a very
weak station, the control should definitely
be turned OFF to assure strongest possible
signal reception.
EXCLUSIVE NOTE FOR U.K.
If your
unit
comes
with
a
3-core
cable
without
a plug,
make
certain
live, neutral
and
(where
appropriate)
earth
leads
are
connected
to
the
proper
terminals.
Check
that the terminals are screwed down
firmly
and no loose strands of wire are present.
