Unit power is turned on and off by pushing the volume (left) knob. In the OFF or "EMG" position, the
pilot headset is connected directly to Com 1 as well as unswitched input #1. This allows communication
capability regardless of unit condition. Any time power is removed or turned
OFF , the audio selector will
revert to fail-safe mode.
The power switch controls all audio selector panel functions, intercom and marker beacon receiver. All
pushbutton selections and menu modes (except Bluetooth telephone association) will be remembered and
return to the last state when turned on.
3.3 Communications Transmit (XMT) Selection (2)

select the desired COM transmitter. A green LED above the button illuminates to indicate that the audio is
selected.
The PMA9000EX-Series has an automatic com receiver selector system. Audio from the selected trans-
ceiver is automatically heard in the headsets and speaker (if selected). You can check this function by
switching from Com 1 transmitter to Com 2 transmitter by pressing the C
