Due to the nature of VHF communications signals, and the size
constraints in general aviation aircraft, it is probable that there will be
some bleed-over in the Split mode, particularly on adjacent
frequencies. PS Engineering makes no warranty about the suitability
of Split Mode in all aircraft conditions.
1.1.1.2 Swap Mode (Switch from Com 1 to Com 2 remotely)
With a yoke mounted, normally open 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.
1.1.1.3 Internal Recorder
The PMA9000EX comes equipped with an in-
ternal recorder. This digital system stores the last
incoming audio from the radio you have selected
for transmit. It can store up to 60 seconds of au-
dio. The pilot and copilot hear the playback.
Because of the continuous nature of AWOS re-
cordings, these will not trigger the recorder cir-
cuits.
1.1.1.3.1 Playback
Recording is automatic. To play back the message, press and hold the
XMT button for the communications radio that is selected for trans-
mit for about 1 second or until the message plays back.
To stop the playback, hold the same button until the playback stops,
about 2 seconds. Then the next 1-second press will play the next ear-
lier message stored.
The playback will stop automatically when the selected com audio
becomes active again. Press the button again to start the message
again. The audio received during playback is NOT stored.
