THE TRANSMITTER
Your Acousticon
transmitter
contains a
sensi
tive
crystal
microphone
located
be­
hind
the
small
opening at
the
top
of the
transmitter.
(see fig. 1)
The
"
A" and
"B"
batteries, three
mini­
ature but powerful vacuum tubes
(in
add.i ­
tion to
a
multitude
of
other
electronic
parts) are also contained within the trans­
mitter.
THE VOLUME CONTROL
A combination volume
control
and ON­
OFF
switch is
located
at
the upper
left
corner
of the transmi tter
(See
fig.
1)
.
When
the
easi
ly turned
volume
con
trol
wheel is
in
the
extreme
left
position,
a
swi tch auto­
matically
disconnects
the batteries. Turning
the
wheel
toward the
right,
automatically
moves the
swi
tch to the
"ON" position.
As you turn the wheel more and more
to
the right the
sounds
become
increasi ngly
louder.
For normal acoustic conditions with
fresh batteries you need a
certain
volume
control
setting depending upon
your hear ­
ing loss.
As
the batteries
become
weaker,
you merely advance
the
volume
con
trol to
compensate
for
reduced
battery voltage.

During a normal
day's
use
you
will als.o
learn to
adjus
t the
volume
control
for van­
ou
s
acoustic conditions.
Always use the
minimum amplification
consistent
with
your
needs,
as
this
will give
you
maximum
"B"
battery life.
When
your Acousticon is not
in
use,
tum the volume control wheel to the
ex­
treme left
position.
Make
sure
it
is
turned
as far as it will go, otherwise
the swi
tch
will not
disconnect
the batteries.
THE NOISE SUPPRESSOR
The plastic plug at
the
end of the receiver
cord
a
lso acts as
a convenient
knob
for
the
noise
suppressor.
This knob can be
adjusted to
either
one
of
two positions, that is, when the
"wing"
on
the knob points toward the white
dot
near the volume control,
the
noise
sup­
pressor
is
on. For
normal
operation,
twist
the knob so that
the
"wing" points
away
from the white
dot.
Th
e noise
suppressor shou
ld
be used
in
noisy
surroundings
such
as
restaurants,
on
noisy
streets,
in the vicinity
of
noisy ma­
chinery, etc.
You will find that in noisy surroundings,
people unconsciously raise their voices
in
an effort
to be heard above the noise.
These
loud
sounds may
