Internal Recorder System
The Intercom 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 message, 
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 accessing the prior message. To cancel the playback, press 
and hold the playback button for two seconds. The next time the button is 
pressed for one second, 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 
PMA8000B.
