SWITCH OPERATION.
Operation
of
the
radio
equipment
is
normal
as
covered
in the
respec-
tive
radio
manuals.
When
more
than
one
radio
is
installed,
an
audio
switching
system
is
necessary.
Audio
switching
is
accomplished
by
a
series
of
selector
switches
located
at the
top-center
of
the
instrument
panel.
They
are
rectangular
in
shape,
internally
lighted,
and
the
face
of
each switch
is
labeled
to
define the
system
it controls.
The
selector
switches have
one
function when
depressed
and
another
function
when
extended.
They
are
designed
to
lock
when
pushed
in to the
depressed
position; they
can
be
extended
by
pressing
full in
and
allowing
them
to
release
to the
extended
position.
Certain
combinations
of
switches
are
interlocked
to
prevent
more
than
one
system
from
being
utilized
at the
same
time.
Depressing
one
interlocked
switch
automatically
disengages
the
others.
All of
the
selector
switches
are
lighted
anytime
the
navigation
light
switch
is
turned
on.
When
a
switch
is
depressed,
its
light
becomes
brighter.
This
light
intensity
of
a
depressed
switch
can
be
controlled
with
the
rheostat
labeled
"DIM AUDIO SW
BRT"
just
below the
selector
switches.
The
following
information
describes
the
various
selector
switch functions.
