3.12 Wired Satcom/Cell Phone input (Serial No F01201 and above)
The PMA450 can accommodate a wired telephone input as well as a Bluetooth connection. However, only
one can be active at a time. The Bluetooth symbol is absent from wired menu.
The wired telephone screen menu is activated when audio is detected from the phone. Sidetone and tele-
phone volume can be controlled from this menu. The telephone audio distribution is the same as Bluetooth,
above.
This menu will switch off 25 seconds after the
incoming
conversation ends, or press End Call.
NOTE: The PMA450 does NOT answer or hang up the wired phone from this menu.
3.13 Internal Recorder and playback
The PMA450 comes equipped with an internal recorder. This digital system stores the last incoming audio
from the radio you have selected for transmit. It can store as many of 8 incoming messages, and up to 45
seconds of audio. The pilot and copilot hear the playback.
Recording is automatic. To play back the last recorded message, press and hold the COM Receive pushbut-
ton associated with the selected radio transmitter for about one (1) second. You can either wait for the mes-
sage to finish playing before accessing the prior message, or cancel the current playback and step back-
ward. To cancel the playback, press and hold the COM receive playback button for two seconds (2). The
next time the button is pressed for one (1) second, the next earlier message will be heard.
The playback
will stop whenever there is more incoming selected com audio, and the message can be replayed
from the beginning by pressing the selected Com Receive button again for 1 second.
