ceiver audio. Push the lower button to select the desired COM trans-

mitter.

The PMA8000B MP3-Series has an automatic selector system. Audio

from the selected transceiver is automatically heard in the headsets

and speaker (if selected). You can check this function by switching

from C

OM 1 transmitter to Com 2 transmitter by pressing the COM 2

transmitter selector pushbutton. Note that the associated Com 2 re-

ceive pushbutton indicator light that is located immediately above the

Com 2 transmitter pushbutton turns green. This guarantees that the

pilot will always hear the audio from the transceiver selected for

transmit.

The PMA8000B MP3 “remembers” the receiver selection, so that

when switching transmitters from C

OM 1 to COM 2, if COM 2 audio

was previously selected, C

OM 1 audio will continue to be heard. This

eliminates the pilot having to switch Com 1 audio back on, after

changing transmitters.

When switching from C

OM 1 to COM 2 while Com 2 was not previ-

ously selected, C

OM 1 audio will be switched off. In essence, switch-

ing the mic selector will not override prior selection of COM receiver

audio.

In normal (not split) modes, the PMA8000B MP3 gives priority to the

pilot’s radio Push-To-Talk (PTT). If the copilot is transmitting, and

the pilot presses his PTT, the pilot’s microphone will be heard over

the selected com transmitter.

In TEL mode, the pilot microphone and headphones are connected to

the cell phone. The pilot PTT will switch the pilot mic to the selected

com transceiver, and allow continued aircraft communications to con-

tinue. (See Page 4—TEL—for more details)

The copilot will also be able to transmit on the other selected radio

with his PTT as well.

Split Mode (Pilot and copilot on different radios)

The split mode is activated by pressing

the C

OM 1 and COM 2 XMT buttons at

the same time. This places the pilot on

OM 1 and the copilot on COM 2.

Pilot on C

OM 2 and Copilot on COM 1 is

not possible.

When the split mode is activated, the
