3.3.1Swap Mode (Switch from Com 1 to Com 2 remotely)

With a yoke mounted, momentary switch, the pilot can change from the current Com transceiver to the other by depressing this switch. To cancel "Swap Mode," the pilot may either press the yoke mounted switch again, or select a different Com with the XMT buttons. .

3.4Audio Selector (4)

Receiver audio is selected through seven momentary, push-button, backlit switches. You will always hear the audio from the transceiver that is selected for transmit.

The users can identify which receivers are selected by noting which of the green switch LEDs are lit. Push buttons labeled Nav 1, Nav 2, MKR (Marker), ADF and AUX (auxiliary) places those receivers into the audio stream. DME audio (if present) will come through when the AUX button is selected. When one of these buttons is pressed, the mode is active, and the LED will illuminate. Press the switch again and it will be "off" and remove that receiver from the audio output.

3.4.1Speaker Amplifier (5)

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 ampli- fier is not active in the "Split Mode”.

Unswitched audio input 1, (the input dedicated to autopilot disconnect, altimeter warning, etc.) will come through the speaker regardless of the speaker button position. Unswitched audio input 2, (the input dedi- cated to a lesser importance input such as GPS waypoint alert) will come through the speaker only when the SPR mode is on. Consult your installer for more information.
