FUNCTION
(Refer

The
output
voltages
of
the
oscillator
control module
are
determined
by
the
module's switch
settings. Figure

shows
the
module’s
pin
numbers
and
lists
the
output voltages
present
when
its
switches
are
activated.

INTRODUCTION
(Refer
to
Fig.
3)
The
2001-6016
Audio
Circuit Selector
Switch
Module
provides
manual
control
of
two
specific (usually speaker)
circuits
in
the
2001
Voice
Communications
System.
Note:
There
are
four
types
of
circuit
selector
modules: the
2001-6016, -6017,
-6018
and
-6019.
The difference
between each
of
these
modules
is
the number
of
circuit
switches. The
2001-6016
has
two
circuit
switches
and
each consecutive
module
increases
its
number
of
switches
by
two.
Figure
3
shows the
2001-6019
for
illustrative
purposes.
