Marker BeaconBeacon 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.

Figure 4-28 Marker Beacon Keys
The Audio Panels provide 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.

ADF/DME Tuning NOTE: When another auxiliary window is turned on, the ADF/DME Tuning Window is replaced on the PFD.
See the Flight Instruments Section for displaying the DME and bearing information windows (ADF) and using the ADF as the source for the bearing pointer.
The G1000 system tunes the ADF receiver (optional) and DME transceiver (standard). The ADF is tuned by entering the frequency in the ADF standby frequency field of the ADF/DME Tuning Window. (The softkey may be labeled ADF/DME or DME, depending on installed equipment.)
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 following ADF/DME information is displayed in the ADF/DME Tuning Window:
• Active and standby ADF frequencies
• ADF receiver mode
• ADF receiver volume
• DME tuning mode (DME transceiver pairing)
When the ADF/DME Tuning Window is displayed, the selection cursor is placed over the standby ADF frequency field.
Turning the large FMS Knob moves the selection cursor through the various fields (standby ADF frequency, ADF receiver mode, ADF radio volume, and DME tuning mode). Pressing the FMS Knob activates/deactivates the selection cursor in the ADF/DME Tuning Window. The ADF frequency is entered using the FMS Knob and the ENT Key.

ADF Tuning
ADF frequencies in the 190.0-kHz to 1799.5-kHz range are entered in the standby ADF frequency field of the ADF/DME Tuning Window. The G1000 System does not tune the ADF emergency frequency, 2182.0‑kHz.
Tuning an ADF frequency:
1) Press the ADF/DME Softkey to display the ADF/DME Tuning Window.
2) Turn the large FMS Knob to place the selection cursor over the standby ADF frequency field.
3) Turn the small FMS Knob to begin data entry and change each digit.
4) Turn the large FMS Knob to move the cursor to the next digit position.
5) Press the ENT Key to complete data entry for the standby frequency.
