AUDIO PANEL
5.2 OPERATION
POWER-UP AND FAIL-SAFE OPERATION
Power-up
The audio panel performs a self-test during power-up. All panel annunciator lights illuminate for approximately twoseconds. Oncetheself-testiscompleted,mostsettings are restored to the ones in use before the unit was last turned off. The exceptions are the speaker and intercom, which are always selected during power up.
Fail-safe Operation
A fail-safe circuit connects the pilot’s headset and microphonedirectlytoCOM1incasepowerisinterrupted or the unit is turned off. In this case, audio is not available on the speaker.
KEY ANNUNCIATORS
Pressing any key on the audio panel activates and deactivates the function. Triangular annunciators above each key illuminate to show when the function is on or off (Figure 5-2).
LIGHTING
Key annunciators and backlighting are controlled automatically by the PFD.
TRANSCEIVER KEYS
The following four (4) transceiver keys appear at the top of the audio panel front panel: COM1 MIC, COM2 MIC, COM1, and COM2 (Figure 5-2). COM audio can be selected by pressing either the desired COM key or by pressing a COM MIC key.
Annunciator

Figure 5-2 Transceiver Keys
COM MIC Keys
Pressing the COM1 MIC key selects the COM1 radio as the active transceiver. Pressing the COM2 MIC key selects the COM2 radio as the active transceiver. The receiver audio key, COM1, or COM2 is also selected. The COM frequency is highlighted in green in the active frequency field of the PFD and MFD.
Only one transceiver can be selected at a time. If COM2 MIC is pressed when COM1 MIC is active, the unit switches to COM2.
COM Keys
Pressing the COM1 receiver key selects the COM1 radio as an active receiver. Pressing the COM2 receiver key selects the COM2 radio as an active receiver. Any combination of radios can be selected separately or simultaneously regardless of the active transceiver selection. The active COM radio is always heard on the headsets.

SPLIT COM FUNCTION |
NOTE: Audio level of the COM radio(s) is controlledbytheCOMvolumecontrolslocated on both the PFD and MFD (see the NAV/COM section).
When a transmitter is keyed, the active transceiver MIC key annunciator blinks approximately once per second. A white TX indication appears next to the active COM frequency on both the PFD and the MFD during transmission.
OPTIONAL COM MUTING
COM muting on receive and COM muting on transmit options can be disabled if desired. Contact a Garminauthorized service center for details.
COM Muting on Receive
NOTE: If COM muting on receive option is enabled, only primary COM radio reception is recorded by the digital clearance recorder.
WhenCOMmutingonreceiveisenabled,allsecondary COM audio is muted during detection of received primary COM audio.
COM Muting on Transmit
When COM muting on transmit is enabled, all secondary COM audio is muted during transmission over the primary COM radio.
NOTE: Split COM performance varies significantlyacrossinstallationsandisaffected by both the distance between the antennas and the separation of the tuned frequencies.
Pressing the COM 1/2 key selects the split COM function. During split COM operation, the COM1,
COM1 MIC, COM2, and COM2 MIC keys are active.
When the COM 1/2 key is selected, COM1 is used by thepilotfortransmissionandCOM2isusedbythecopilot. The COM1 MIC annunciator blinks when the pilot’s microphone is keyed and the COM2 MIC annunciator blinks when the copilot’s microphone is keyed.
Inthismode,boththepilotandthecopilotcantransmit simultaneously over separate radios. The pilot can still monitor NAV1, NAV2, DME, ADF, and MKR audio as selected, but the copilot is only able to monitor COM2.
SplitCOMmodeiscancelledbypressingtheCOM 1/2 key again.
PA FUNCTION
A passenger address function is provided by pressing the PA key to deliver messages. Push-to-talk (PTT) must be used to deliver PA announcements over the headsets.
WhenPAisselectedontheaudiopanel,theannunciator blinks about once per second, the COM MIC annunciator is no longer lit, and the active COM frequency for that audio panel changes to white, indicating that there is no COM selected.

AUDIO PANEL
SPEAKER
All of the radios can be heard over the cabin speaker. Pressing the SPKR key selects and deselects the cabin speaker. Speaker audio is muted when the PTT switch is keyed.
The speaker volume is adjustable above and below a nominal value. Contact a Garmin-authorized service center for details.
MARKER BEACON RECEIVER
Description and Operation
The audio panel marker beacon is used as part of the ILS system. The marker beacon receiver is always ON and receives at 75 MHz. The audio panel provides a marker audio muting capability.
NOTE: The GMA 1347 is capable of driving external marker beacon lamps.
The receiver detects the three (3) marker tones, outer, middle, and inner, and illuminatesthe appropriate marker beacon indicators. The marker indicators are located to the left of the Altimeter on the PFD (Figure 5-4). The outer marker frequency is 400 Hz with a blue indicator, the middle marker frequency is 1300 Hz with an amber indicator, and the inner marker frequency is 3000 Hz with a white indicator. Refer to Table 5-1 for a summary of the marker beacon signal characteristics.
NOTE: The marker beacon indicators operate independently of the marker beacon audio and cannot be turned off.
WhentheMKR/MUTEkeyisselected,theannunciator light illuminates and the audio signal can be heard over the speaker or headsets during marker reception.
When the MKR/MUTE key is annunciated and a marker beacon tone is received, pressing the MKR/MUTE key mutes the audio but does not affect the annunciators. Theaudioreturnswhenthenextmarkersignalisreceived. If the MKR/MUTE key is pressed during signal reception, while marker beacon audio is muted, marker audio and the MKR/MUTE key annunciator light are turned off.
The marker beacon audio output level is adjustable by a Garmin-authorized service center.
Marker Beacon Signal Sensitivity
Press the HI SENS key (Figure 5-3) for increased marker beacon signal sensitivity. The HI SENS function is used to receive an earlier indication of nearing a marker during an approach.
Figure 5-3 Marker Beacon Keys
MARKER BEACON VOLUME ADJUSTMENT
The level of marker beacon receiver audio can be adjusted by a Garmin-authorized service center, if desired.

NAVIGATION RADIOS
Pressing NAV1, NAV2 or optional DME or ADF selects and deselects the radio source and the annunciator (Figure 5-5). Selected audio can be heard over the headset and the speakers. All radio keys can be selected independently.
When no further navigation radio audio is heard, the amount of background noise is reduced by the Master Avionics Squelch (MASQ) feature.
