MARKER BEACON RECEIVER (OPTIONAL)
NOTE:
The marker beacon indicators operate independently of marker beacon audio and cannot be turned
off.
The marker beacon receiver is used as part of the ILS. The marker beacon receiver is always on and detects
any marker beacon signals within the reception range of the aircraft.
The receiver detects the three marker tones – outer, middle, and inner – and provides the marker beacon
annunciations located to the left of the Altimeter on the PFD.

Figure 4-28 Marker Beacon Key on Audio Panel
The Audio Panel provides three different states of marker beacon operation; On, Muted, and Deselected.
Pressing the
MKR/MUTE
Key selects and deselects marker beacon audio. The key annunciator indicates when
marker beacon audio is selected. Marker beacon audio is not heard when the annunciator is off or when the
annunciator is on with the marker beacon audio muted.
Turning Marker Beacon Audio On
With the MKR/MUTE annunciator off, press the
MKR/MUTE
Key to enable marker beacon audio.
Muting Marker Beacon Audio
During marker beacon audio reception, press the
MKR/MUTE
Key to mute the audio. The MKR/MUTE
annunciator remains lit, but the current marker tone is silenced. Audio muting deactivates automatically and
marker beacon audio is heard when the next marker beacon signal is received.
Deselecting Marker Beacon Audio
To deselect marker beacon audio, press the
MKR/MUTE
Key twice during marker beacon reception (once to
mute, once more to deselect) or once if a marker beacon signal is not detected.
