Swap Mode (Switch From Com 1 To Com 2 Remotely); Audio Selector - PS Engineering PMA8000B Pilot's Manual And Operation Manual

Note: Split Mode does not turn off Nav, ADF, or Aux selected audio to
pilot. However, the copilot will only hear the selected com receiver and
unswitched inputs.

Swap 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.

Audio Selector (4)

Navigation receiver audio is
selected through five momen-
tary, push-button,
switches. You will always
hear the audio from the se-
lected transceiver.
The users can identify which receivers are selected by noting which
green switch LEDs are lit. Navigation aid audio push buttons are la-
beled Nav 1, Nav 2, MKR (Marker), ADF and AUX (auxiliary).
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.
In SPLIT mode, only the pilot will hear selected navigation audio.
Telephone (TEL) (9)
The TEL mode serves as a full duplex interface and
distribution for telephone systems such as AirCell
or portable cellular phones with earpiece jacks.
Pressing the TEL button activates the telephone
mode.
This connects the telephone to the users as follows:
In ALL intercom mode, all crew and passengers
will be heard on the phone when they speak. Com and other selected
radio audio is also heard in the headsets. If the pilot or copilot pushes
the radio PTT, their mic will be transferred to the selected Com radio.
