Internal Recorder System
The Internal Recording System is a continuous loop recorder, (last message
received will be the first heard), the recorder has 45 seconds of recording
time, or up to eight messages. There are no buttons to press to start re-
cording. The system automatically begins to record the instant the radio se-
lected for transmit becomes active. Only the pilot and copilot will hear the
playback audio.
To play back the last recorded mes-
sage, you press and hold the COM
RCV pushbutton associated with the
selected radio transmitter for about
one second. You must wait for the
message to stop playing before ac-
cessing the prior message. To cancel
the playback, press and hold the play-
back button for two seconds. The next time the button is pressed for one sec-
ond, the next earlier message will be heard. If the radio becomes active while
a message is playing, the message playback will stop. The new audio will
not be stored. Press play to restart the message you were playing.
Messages are lost when a different radio is selected for transmit.
The playback will stop whenever there is more incoming selected com audio,
and the message can be replayed from the beginning. Note: an external play-
back button may also be installed in a convenient location.
Public Address Function (if enabled)
To enter PA mode, press both the Mute and SPR buttons at the same time.
The Mute and SPR LEDs will blink to indicate the audio panel is in PA
mode. The copilot can continue to use the selected com while the pilot will
be heard over the speaker. To exit push Mute and SPR again. This mode is
also reset when power is cycled.
Backlighting
The white text backlighting is controlled by the aircraft dimmer, while the
green indication LEDs are automatically controlled by the light sensor on the
PMA8000C.
