we strongly suggest that you read the complete instruction
book thoroughly. Only then will you get the utmost enjoy-
ment and maximum performance from this superb instrument.

ground. Turn the dial slowly. The
:3) 3:30;: moment you hear a steady tone,

you know you have located a sta-
tion broadcasting in multiplex. It
is normal for some faint sound to
be heard above the steady tone.
Carefully adjust for the cleanest
tone combined with minimum dark
area at the center of the tuning in-
dicator tube. Turn the Selector switch back to'the stereo position,
and enjoy a station perfectly tuned for multiplex.

SCOTT AUTO-SENSOR CIRCUIT (Series 310 and 4312)

The amazing auto-sensor actually switches your tuner to stereo
automatically when you are tuned to a station broadcasting in
multiplex. If the station returns to normal monophonic operation,
the tuner will automatically switch back to monophonic reception.
You never have to think about resetting the controls.

turn the Selector Switch to Automatic Stereo and set the Stereo

Threshold control to 0. Tune

mownc locate a stereo signal, a pilot light

You will hear a clicking sound
when this occurs.

If you are only interested in re-
ceiving stereo broadcasts, you can
turn the Selector switch to the
stereo position. In this position,

you will only hear a station if it is actually broadcasting multiplex
stereo. If the station is transmitting monophonic programs, you
will receive no signal from your tuner. On the other hand, if you turn
your Selector switch to FM mono, you will receive all stations mono-
phonically, Whether they are broadcasting in stereo or not.

cast is in progress, simply turn the

MONO. . SYEEEO ception from your Scott tuner. You
or; . . SUB. CH} Hm N do not have to vary any settings on

your stereo amplifier. The tuner au-
tomatically provides a monophonic
signal at both outputs. Therefore,
even though the program is mono-
phonic, you will still hear sounds
from both speakers without further
adjustments.

If a particular station happens to be noisy, much of the material
provided in the Appendix will be useful here as well. In particular,
use of the amplifiers scratch filter, or the tuners Stereo Noise Filter
should be examined.

(Model 310 and .4312 The auto-sensor circuitry will instantly
switch the tuner to receive monophonic programs if no stereo multi-
plex signal is present. It is not necessary to set the Selector switch
for FM mono. Simply leave the switch in the Automatic Stereo
position, unless you want monophonic reception at all times.

LISTENING TO AM BROADCASTS (335 series)

Your tuner incorporates Scotts famous wide-range AM cir-
cuitry which is capable of providing AM reception virtually in-
