Inputs 1, 2 and 4 are fixed (1:1), and any audio level adjustments must be made at the input source. Un-

"Swap" Button Functions
Function 1:
When a momentary, normally open, push-button switch is connected between pin 20 on the J2
connector and aircraft ground, the user can switch between Com 1 and 2 by depressing this switch without
having to turn the mic selector switch. This yoke-mounted switch eliminates the need to remove your hands
from the yoke to change transceivers. The transfer of TX indication from Com 1 to Com 2 shows that the
swap has been initiated; there is no dedicated swap indicator.
Function 2:
The remote Swap button also acts as a remote intercom mode selector. Holding the Swap button
for more than 1 second will cause the ICS button to increment in the same way as if the front panel ICS
button is pushed. [ISO-ALL-CREW-ALL-ISO] The panel indications track the intercom mode.
2.4.9
TEL (Duplex) Function for wired Satellite or Cell Phones
Audio streams selected by the intercom mode are provided to the Tel output, and audio from Tel is presented
to the headset. This allows a telephone-like audio interface.
The TEL mode in the AeroPanel 100 is compatible with many telephones with hands-free headset interfaces.
A jack can be installed somewhere on the aircraft panel. The wired interface jack is connected with the
AeroPanel 100 as shown:
The AeroPanel 100 is compatible with most Bluetooth® enabled devices for making and receiving telephone
calls through the aircraft audio system.
