Installation and Operator’s Manual

In ISO intercom mode, when the PMA8000C is in the TEL mode, the pilot position is in the "Phone
Booth." Only the pilot will hear the telephone, and only he will be heard. He will also have access to COM
1 or 2, and will transmit on that radio using the PTT. All selected audio is provided.
Warning:
United States FCC Regulations contained in 47 CFR § 22.925 contain prohibition on airborne operation of
cellular telephones. “Cellular telephones installed in or carried aboard airplanes, balloons or any other type
of aircraft must not be operated while such aircraft are airborne (not touching the ground). When any air-
craft leaves the ground, all cellular telephones on board that aircraft must be turned off.”
NOTE
Because the cell phone uses an intercom circuit, all stations on that circuit will lose intercom capability
when the cell phone is in use. Intercom conversations will still be present if the cell phone provides side-
tone, or if the audio panel is modified for telephone sidetone.
PS Engineering does not guarantee compatibility with personal cellular telephones.

3.11.2.1 Cellular telephone sidetone
As shipped from PS Engineering, the PMA8000C does provide cellular telephone sidetone (the user’s
voice fed back to the headset). Some cell phones do provide sidetone. In PMA8000C Telephone sidetone
can be enabled/disabled by pressing the COM 3 XMT and ADF buttons for more than one second.
3.11.3 Power on announcement
If the Intercom or Music Distribution is changed from the factory default, the configuration will be played
when the unit is powered up. To defeat this announcement, press the COM 3 XMT and AUX buttons at the
same time. The feature can be enabled again using the same sequence.
3.12 Internal Recorder and playback
The PMA8000C comes equipped with an internal recorder. This digital system stores the last incoming au-
dio from the radio you have selected for transmit. It can store as many of 8 incoming messages, and up to 60
seconds of audio. The pilot and copilot hear the playback. It is also possible to modify the unit to exclude
the copilot from the playback, and annunciation playback. Contact PS Engineering, for more details.
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 backward.
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.
