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.
DME TUNING
NOTE:
When another auxiliary window is turned on, the DME Tuning Window is replaced on the PFD.
NOTE:
When turning on the Avionics for use, the system remembers the last frequency used for DME tuning
and the NAV1
,
NAV2,
or
HOLD
state prior to shutdown.
The PFD tunes the optional DME transceiver. The UHF DME frequency is tuned by pairing with a VHF NAV
frequency. DME frequency pairing is automatic and only the VHF NAV frequency is shown.
The DME Tuning Window is located to the right of the HSI in the lower right corner of the PFD. The DME
transceiver is tuned by selecting NAV1, NAV2, or HOLD in the DME Tuning Window. Pressing the
DME
Softkey switches the DME Tuning Window on and off.
