Beacon Receiver
The
marker
beacon is used
as
part of
an ILS approach and
in
certain
instances,
to
identiiy
an
airway. In addition to
the
normal marker
beacon
functions,
the
GMA 340
provides an
audio
muting
function.
The
lamps
illuminate,
and
an associated keyed-
rone is heard
(when MKR audio
is selected),
when
the
aircraft
passes
over a
75
MHz
marker
beacon
transmitter.
The
lamp and audio keying
for
ILS approach
operation
are
summarized

The ma¡ker
beacon
audio level
is
aligned
at the
factory
to
produce
its
rated audio output.
Horvever,
rhe
audio
output
level is adjustable by
your installing
agency.
The
GMA
340's
marker
beacon receiver controls are located
on
the
left
side
of the front
panel
(i-a).
The
SENS
buuon
selects
either high or low sensitivity
as
indicated by the
HI
or LO LED being
iii.
Los'sensitivity
is used
on
ILS approaches
while high
sensidvity allows
operation
over airway
;narkers
or to
get
an earlier
indication
of nearing the outer marker
during
an approach.
The marker audio is
initially
selected
by
pressing the MKRi/mute
button
(2).
If no
marker
bea-
con signal is received, then
a second
button
press
will
deselect
the marker
audio.
This
operation
is
simila¡ to
selecting any
other
audio source
on
the
GMA
340.
Howeve¡
if
the second
button
press
occurs rvhile
a
marker beacon signal is received, then the marker audio is
muted but no¡
deselect-
ed.
The button's LED
will
remain
lit
to
indicate
that
the source is
still
seìected.
When
the current
marker signal
is
no longer received, the audio
is
automatically
un-muted. While in
the muted
state,
pressing
the MKR/mute
buuon
deselects
the marker
audio.
The button's LED
will
extinguish
to
indi
cate
that
the marker audio
is
no
longer
selected.
The
marker
beacon lamps operate independently
of
any audio selection and cannot be
tumed
off.
The GMA 340 can drive extemal marker lamps
if
required.
