AUDIO PANEL AND CNS
MARKER BEACON RECEIVER
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.

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.
During marker beacon audio reception, pressing the
MKR/MUTE
Key mutes the audio but does not affect the
marker annunciations (Figure 4-27). The marker tone is silenced, then waits for the next marker tone. The
MKR/MUTE
Key Annunciator is illuminated, indicating audio muting. The audio returns when the next marker
beacon signal is received. If the
MKR/MUTE
Key is pressed during signal reception (O, M, I indication) while
marker beacon audio is muted, the audio is deselected and the
MKR/MUTE
Key Annunciator is extinguished.
Pressing the
HI SENS
Key switches between high and low marker beacon receiver sensitivity. The HI SENS
function (annunciator illuminated) is used to provide an earlier indication when nearing a marker during an
approach. The LO SENS function (annunciator extinguished) results in a narrower marker dwell while over a
station.
