9.3 Concurrent Messages
When a recorded message or audio annunciation is playing, the other audio
source is momentarily inhibited. For instance, if an IRS message is being
played, the audio annunciation will not begin until the IRS message is fin-
ished. Conversely, the IRS recording cannot be played as long as there is an
aural alert being played. There is no recording made if playing a recording
or annunciation.

cating that the Mic Selector switch position is no longer current. To cancel
"Swap Mode," the pilot may either press the yoke mounted switch again, or
turn the Mic Selector Switch to the Com that is active.
4 Receiver Audio Selector (All models)
Receiver audio is selected through two momentary and six latched, push-
button, backlit switches. Com 1 and Com 2 are the momentary switches.
Because the rotary microphone selector switch controls what transceiver is be-
ing
heard, the Com l and Com 2 push-buttons are of the momentary type and do
not remain in when selected. This is also part of the "auto” function. You will
always
hear the audio from the transceiver that is selected for transmit by the
rotary mic selector switch.
The users can identify which receivers are selected by noting which of the
green switch LEDs are illuminated. Push buttons labeled Nav 1, Nav 2, DME,
MKR (Marker), ADF, AUX (auxiliary), and SPR (Speaker) are "latched" type
switches. When one of these buttons is pressed, it will stay in the "in" position.
Press the switch again and it be in the "out" position and remove that receiver
from the audio.
4.1 Speaker Amplifier
The "SPR" in the push-button section stands for speaker. This switch will
place all selected audio on the cockpit speaker when this switch is selected.
NOTE: Except for the unswitched audio, the speaker amplifier is not active in
the "Split Mode."
Unswitched audio, (autopilot disconnect, altimeter warning, etc.) will come
through the speaker regardless of the speaker button position.
