This pilot’s guide provides operating instructions for the PMA8000D Audio
Panel for dual panel systems. Please read it carefully before using the equip-
ment so that you can take full advantage of its capabilities.
This guide is divided into main operating sections such as Transceiver Selec-
tion, Audio Selector, Intercom, and Marker Beacon Receiver, and special
functions. The center section provides a reference that you can remove.
PMA8000D controls
Power Switch (1) (EMG-Fail Safe Operation)
The power switch controls all audio selector panel functions, intercom and
marker beacon receiver.
When the unit is turned off, either by pressing the volume control, or if the
breaker is pulled removing power, the PMA8000D is in Fail-Safe mode. In
this mode, the crewmember’s headset is connected to COM 1 for transmit
and receive. The fail safe audio will only be heard in the left ear of a stereo
headset.
NOTE: In the event of failure in both audio panels, both will default to COM
1. If both crew members attempt to transmit at the same time, the modulation
may be compromised, depending on the microphones used. Therefore, only
one crew member should transmit if both audio panels fail.
Communications Transmit (XMT) Selection (2)
To select COM 1 COM 2 or COM 3 for transmit, press the button on the
bottom row, next to the XMT legend. The bottom and top button indicators
light, showing that you will transmit and receive on the selected radio.
Communications Receive (RCV) Selection (3)
To listen to the other radio, press the upper button, in the RCV (receive) sec-

202-890-0304 Page 3

tion. When a com is selected for receive, it
will stay selected until manually deselected,
even if you select, and then deselect its trans-
mitter.
The PMA8000D gives priority to the pilot’s
audio panel radio Push-To-Talk (PTT) if both
panels have selected the same transmitter.
If the Monitor function is activated
(Monitor), the audio from this radio will be muted when the primary radio
(selected for transmit) is receiving a signal.
In cell phone mode, the crewmember is connected to the cell phone, but still
hears the COM radios selected. The radio PTT will switch the mic to the
selected com, and allow continued aircraft communications to continue. (See
Page 6—Cellular telephone—for more details)
Audio Selector (4)
These buttons select the switched navi-
gation receivers. The DME input (if
present) is also shared with AUX. In
SPLIT mode, only the pilot will hear
selected navigation audio.
Cockpit Speaker (5)
This button will place all selected audio on the crewmember’s
cockpit speaker when this switch is selected.
Depending on installation, important audio alerts such as radar
altimeter or autopilot disconnect will come over the speaker
even if it is not selected, while other unswitched inputs, will only be present
if the SPR button is selected. Consult your professional avionics installer for
these important configuration details.
Intercom Operation
IntelliVox® VOX-Squelch
IntelliVox® is PS Engineering’s proprietary intercom squelch control.
Through the use of digital processors, each microphone is monitored, and
opens instantly when human speech is detected. This results in seamless con-
versations aboard the airplane for crew and passengers, without syllable clip-
ping or fatigue-inducing noise.
No adjustment of the IntelliVox® squelch is necessary. There is no field ad-
justment. The system is designed to block continuous tones, therefore people
humming or whistling in monotone may be blocked after a few moments.

Receiver selection

Page 4 202-890-0304 Rev. 2 PMA8000D Pilot Guide
For consistent performance, any headset microphone must be placed within
¼-inch of your lips, preferably against them. (ref: RTCA/DO-214, 1.3.1.1
(a)). It is important to have the microphone element parallel to your mouth,
and not twisted inside the cover.
Note: For optimum microphone performance, we recommend use of a Mi-
crophone Muff Kit from Oregon Aero (1-800-888-6910,
www.oregonaero.com ). This will not only optimize VOX performance, but
will improve the overall clarity of all your communications.
You should also keep the microphone out of a direct wind. Moving your
head through an air stream may cause the IntelliVox® to open momentarily.
This is normal. The IntelliVox® is designed to work with normal aircraft
cabin noise levels (70 dB and above). Therefore, it may not always recognize
speech and clip syllables in a quiet area, such as in the hangar, or without the
engine running. This is also normal.
Intercom Volume Control (7)
The small volume control knob adjusts the loudness of the intercom for the
crewmember connected to the audio panel. It has no effect on selected radio
levels, music input levels or passengers' volume level.
The larger, outer volume control knob controls intercom volume for the pas-
sengers on the copilot audio panel only. It has no effect on radio or music
levels. The pilot panel outer knob has no effect.
Mono Headsets in Stereo Installation
The pilot and copilot positions work with stereo or mono headsets.
Intercom Modes (8)
The “ICS” pushbutton switch on the left side of
the panel provides the selection of the intercom
modes.
This button cycles through the intercom modes,
from top to bottom, then bottom to top as: ISO,
ALL, CRW and CRW, ALL, ISO. An LED
shows which mode is currently active.
While in ISO Mode, the pilot can elect to hear music #1. First, be sure that
the ISO mode is selected. Then press and hold the COM 3 button, then hold
the ICS mode button for more than one second. The ICS indicator will blink
slowly to indicate music is present in ISO. The music muting will be the
selected mode. This feature is not remembered through power cycles.
The following charts show the audio presented to the Pilot, Copilot, and pas-
sengers on an intercom expansion unit.

Marker Beacon Operation (9)
The Marker Beacon Receiver uses visual
and audio indicators to alert you when the
aircraft passes over a 75 MHz transmitter.
The Blue lamp, labeled “O”, is the Outer
Marker lamp and has an associated 400-
Hertz 'dash' tone. The lamp and tone will
be keyed at a rate of two tones/flashes per second when the aircraft is in the
range of the Outer Marker Beacon.
The Amber lamp, labeled “M”, is the Middle Marker lamp and is coupled
with a 1300 Hertz tone. It is keyed alternately with short 'dot' and long 'dash'
bursts at 95 combinations per minute.
The White lamp, labeled “I”, is the Inner marker and has a 3000 Hertz 'dot'
tone. The lamp and tone will be keyed at a rate of six times per second.
The audio from the Marker Beacon Receiver can be heard by pushing the
"MKR" push-button switch momentarily.
A marker AUD LED will indicate the marker beacon audio has been se-
lected.
To adjust the volume level, there is a service adjustment located on the top
of the unit.
The Marker Sensitivity is controlled by an external switch, labeled MKR HI
sense. Of switched to ground, the marker receiver is in high sensitivity, oth-
erwise, the marker is in LOW sense by default, and the “LOW” indicator on
the audio panel is illuminated.
Holding the MKR button for one second activates marker test lamp, labeled
"T/M" and illuminates all three lamps simultaneously to assure the lamps
(internal and external) are in working order. T/M does not activate MM auto-
pilot sense output. Releasing the button returns to the last sensitivity.
Pressing the marker mode select (“T/M”) for one second will also cause the
marker audio to mute for that beacon. The next beacon received will re-
activate the audio.
Bluetooth ® Telephone
In a dual PMA8000D Installation, the pilot’s Bluetooth transceiver services
music and telephone for the pilot only. It is not possible to share the phone
connected to the pilot’s audio panel. If the pilot’s cell phone does not pro-
vide sidetone on the Bluetooth connection, the pilot will not hear himself on
the telephone.
When the pilot connects to the Telephone, the audio panel must be in ISO

Quick reference PMA8000D Operation
This pull-out section covers advanced operation of the PMA8000D.
Bluetooth Connection
1. Turn on the PMA8000D.
2. From your Bluetooth enabled device, search for other devices,
and select either the “PMA8000D Pilot” or “PMA8000D Copi-
lot.”
3. If an access code is required, enter “0000” to connect to the
PMA8000D, unless this is changed (see FAQ #2)
You can now make and receive calls with the audio directed through
the audio panel, and stream music to Music input 1.
The Bluetooth module can be turned off, if desired, by pushing the
AUX and ADF buttons while the unit is being turned on.
The module will reset when unit power is cycled.
Bluetooth® FAQ
1. Some Bluetooth terms to know:
Hands Free —audio panel acts as a hands free telephone hand-
set
Audio Sink —the audio panel will receive music audio stream-
ing from the Bluetooth Device
Stereo headset —the audio panel will receive music audio
streaming from the Bluetooth Device.
Pairing —is when two Bluetooth devices establish communica-
tion and “agree” to connect. This occurs the first time the devices
“meet” and they will store the information to reconnect easily in
the future.
Discoverable — the PMA8000D is always “discoverable.” That
means it will allow any Bluetooth device within range to detect
its presence and attempt to pair. Pairing will only occur when
both devices agree, so you will have to accept the pairing on your
device.
Connection —this occurs when Bluetooth devices that have
been previously paired see each other again and reestablish their
communication. This can happen automatically, or by prompting
the user to accept the connection again. The PMA8000D will
always look for paired devices when it is turned on, and connect
with the first one that allows connection.

Page 8 202-890-0304 Rev. 2 PMA8000D Pilot Guide
2.What access code do I use?
a. If your phone requires an access code to complete the pairing,
you can use 0000 (all zeros). See the table if you wish to
change the audio panels access code to “1234,” or “1111”.
3. How many devices can I pair with the audio panel?
a. You can pair up to eight devices. After that, the audio panel
will “forget” one device when another is added. Due to the
nature Bluetooth, we can’t predict which device will be
dropped. If your desired device is dropped, simply re-pair the
one you want.
4. How many devices can I use at the same time?
a. You can connect multiple devices such as a Smartphone and an
iPad for music, but only one telephone can be connected to any
audio panel at a time.
5. Can I use a different music source other than my phone?
a. Yes, you can. However the music device, must be paired and
connected first, before the telephone is turned on. In Smart-
phone such as Motorola Droid, you should specifically disable
the Bluetooth phone or music portion, depending on function to
be used. Note, if an iPhone is connected second, you may not
be able to stop it from taking over the music. Some phones
must manually select the PMA8000D as an audio source for
the phone after the music is connected.
6. My Smartphone didn’t reconnect, what do I do?
a. It is most likely that the PMA8000D dropped the pairing either
because of added pair that exceeded the limit, or because of
some corruption in the stored information. Simply un-pair by
deleting the PMA8000D in your Bluetooth phone, and re-
pairing with the audio panel. This is often true if you leave the
Bluetooth range, and return while the audio panel is still on.

7. Can I play my laptop movie audio?
a. If your laptop is compatible as Bluetooth A/V source (not all
are), yes. Just add the PMA8000D as a Bluetooth device as
you would a stereo speaker device. There are also Bluetooth
devices available (such as the Sony TMR-BT10A Bluetooth
Transmitter Adapter) to plug into the audio output jack that
will enable you to stream music to the audio panel. Note: lap-
top computers with spinning hard drives may fail to work
abut 7,500’, due to a loss of air pressure on the disc mecha-
nism.
8. Can the Bluetooth be played through Music 2?
a. No. However, you can engage Music Function, “Music 1, all
headsets.”
9. My music quality is very poor, and can only be heard in tele-
phone mode, what’s wrong?
a. Check your Smartphone, and be sure that it is paired with the
PMA8000D as a “speaker” or “wireless speaker” in A2DP
mode.
Bluetooth Telephone Operation
In a dual PMA8000D Installation, the pilot’s Bluetooth transceiver
services music and telephone for the pilot only. It is not possible to
share the phone connected to the pilot’s audio panel. If the pilot’s
cell phone does not provide sidetone on the Bluetooth connection,
the pilot will not hear himself on the telephone.
In order for the pilot to use the cell phone, the audio panel must be in
the ISO mode on the intercom to facilitate the call. The pilot will still
have complete access to the aircraft radios, and will transmit on the
selected com when he uses the radio push-to-talk.
The copilot panel’s Bluetooth transceiver will provide music and tele-
phone for the copilot and the passengers.
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 air-
borne (not touching the ground). When any aircraft leaves the ground,
all cellular telephones on board that aircraft must be turned off.”

Page 10 202-890-0304 Rev. 2 PMA8000D Pilot Guide
The copilot’s Bluetooth device connects the copilot and passengers to
this phone and music source. This connects the telephone to the users
as follows:
Heard on the phone *Passengers have exclusive use of phone
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, but
will be heard if the phone is connected.
If the copilot’s cell phone does not provide sidetone, the intercom can
be configured by pressing the COM 3 and ADF buttons for more than
one second. This will NOT provide sidetone in ISO mode.
Music Muting
Music source #1 (front panel jack and Music 1 input) has four muting
modes, which are announced in the headset as they are activated.
These are: Radio Mute (aircraft radio mutes music), Intercom Mute
(intercom conversation mutes music), Mute on (both radio and inter-
com mutes music), and Mute off (nothing interrupts music). Press the
Mute button to cycle through the modes in sequence. Mode annuncia-
tion will be heard in crew headsets only
Music #2 has muting either on, or off, and is controlled by holding the
MUTE and AUX buttons for more than one second.
Music in pilot isolate mode
The crewmembers can elect to listen to Music 1, even in the Isolate
mode. While already in the ISO mode, press and hold the ISO button
until the indicator blinks. The ICS indicator will then blink every few

seconds to indicate this mode is active. Music muting will follow the
modes listed above.
Smart Function Keys (SFK) Configuration
These secondary functions give the PMA8000D some special capa-
bilities.
“Intercom” Alternate Intercom mode allows the passengers and crew
to converse, in ALL intercom mode, without distracting the crew from
radio duties. The passenger microphones are cut out from the crew
when the radio is active, and the passengers never hear aircraft radios.
Press and hold the COM 3 button until the audio annunciation starts
(about 1 second) to activate the function, and you will hear “Alternate
Intercom Function.” Hold the button again to exit, and you will hear
“Standard Intercom Function.” This mode is invoked from either au-
dio panel, and applied to both crew positions.
“Monitor” activates a Monitor Mode. In this case, the audio from
the COM radio that is selected for transmit will mute the other COM
audio when it is active. For example, if COM 1 is selected to transmit
to ATC, but COM 2 is receiving weather information; the ATC will
mute the audio from the weather while ATC is transmitting. In Moni-
tor mode, the RCV COM indicator will blink every few seconds as a
status indication. The monitor applies to the individual crewmember’s
audio panel. Monitor mode is reset to off when the unit is turned off.
For the copilot’s panel, “Music” controls music distribution, and has
three states; Standard Music Distribution, Alternate Music Distri-
bution and Music 1 All Headsets.
Music 1 (the Bluetooth device or the Music 1 input on the rear con-
nector) can be distributed to all headsets depending on intercom
mode. In the Pilot’s panel, “Music” just turns Music 1 on or off.

In Standard Music Distribution, Music 1 is provided to the copilot,
and Music 2 is independently provided to the passengers.
In Alternate Music Distribution, Music 1 is provided to copilot and
passengers in the ALL intercom mode, and Music 2 becomes active,
for the passengers only, when the intercom is in the CREW mode.
The front panel jack is also available to the passengers in the ISO and
ALL intercom modes.
The PMA8000D will announce the Alternate Intercom and Music
distribution functions at unit power up. To defeat the announcement at
power up, hold the COM 3 and AUX buttons for about two seconds.
The feature can be enabled using the same sequence.
“Smart” Front Panel Jack
When music 1 is actively playing through the rear panel input, the
front jack automatically becomes an advisory audio input, and is NOT
muted by radio or intercom conversations. This is useful for connect-
ing portable traffic or terrain alert devices. If Music 1 is not active, the
mute mode should be deselected.
Recorder Playback
The internal recorder is always storing the audio from the radio se-
lected for transmit. To play back
the last incoming audio, hold the
RCV (top) button on the radio
selected to transmit for one sec-
ond, and release. The playback
will start. Playback stops if the
radio becomes active, but the new
incoming message will not be
recorded. When the radio stops, press play and you will be in the
same message you had playing.

modeon the intercom to facilitate the call. The pilot will still have complete
access to the aircraft radios, and will transmit on the selected com when he
uses the radio push-to-talk.
The copilot panel’s Bluetooth transceiver will provide music and telephone
for the copilot and the passengers.
The copilot’s Bluetooth device connects the copilot, pilot and passengers to
this phone and music source. This connects the telephone to the users as fol-
lows:
Heard on the phone
*Passenger exclusive telephone conversation.
In cases where the copilot’s cellular telephone doesn’t provide sidetone, the
audio panel can be configured, by holding the COM 3 and ADF buttons for
more than one second, to create sidetone for you. This sidetone is NOT pre-
sent in ISO mode.
Stuck Microphone Protection
The PMA8000D will sense if the pilot or copilot radio PTT remains keyed
for more than 32 seconds. When a stuck mic is detected, the key input is
ignored, and the other crewmember can transmit normally. If the stuck be-
comes ungrounded, normal operation is restored.
Utility Jack
The 2.5 millimeter (3/32”) jack on the front of the PMA8000D serves two
functions, Advisory audio input and Music input (wired)
Audio Advisory Input
The front jack can be used as a priority advisory input for auxiliary systems
such as a GPS terrain advisory or portable traffic watch system. To prevent
radio or intercom from muting this input, press the “Mute” button to until
“Mute Off” is heard.
NOTE:The front jack is no substitute for the certified installation of alerts
such as the GPS waypoint or autopilot tones. These still must be hard wired
into the back by your installer.
“Smart Jack” Function
When the PMA8000D has an audio signal on music #1 from the rear connec-
tor, the front panel jack automatically becomes a Priority Advisory input,

and is heard in the crew headphones, and this input will NOT be muted by
radio or intercom., if the Music 1 audio is actively playing.
Music Input
When used as a music input, the front panel jack (and Bluetooth) music are
treated as Music #1. Using the Music function button, it can be distributed to
all users, depending on the intercom mode.
Smart Function Keys (SFK)
With voice feedback, the configuration process is self-directed. These func-
tions are non-essential and non-required and as such are only an accessory
capability. Note: annunciations will be stopped by any audio received on the
com radio selected for transmit.
Looking at the front panel you’ll notice that the COM 3, AUX, MUTE and
SPR buttons have “Function” assignments.
To use these function keys, Intercom,Monitor, and Music –press and
hold the desired function key until the audio annunciation of the mode be-
gins.
There are three special functions. “Intercom” function is related to the in-
tercom audio distribution, and allows the crew to mute passengers’ intercom
feed when radios are active. The “Monitor” function mutes the secondary
communication radio audio when the primary radio (the one selected to
transmission) is active. “Music” function controls how music is distributed
from the crewmember's audio panel.
The volume of the function selection annunciations and recorder playback
can be adjusted through a hole on the top of the unit marked “ANN VOL.”
“Intercom” Function
Function Intercom controls the distribution of aircraft radio and passenger
intercom. In the “Standard intercom function” mode, aircraft radios are dis-
tributed to all, when the intercom is in the ALL mode. In CREW
mode, only the pilot and copilot positions will hear aircraft radios.
When in “Alternate Intercom Function,” the passengers will
NEVER hear aircraft radios, even in the ALL mode. In addition,
when in the ALL intercom mode, passengers will be able to con-
verse with the crew, unless the aircraft radio becomes active, when the inter-
com audio from the passengers to the pilot and copilot is stopped, so the

202-890-0304 Page 17
Oct. 2014 PMA8000D Pilot Guide
crew can focus on the radio. Passengers will always be able to talk to each
other.
To activate this function hold the COM 3 XMT button until the audio an-
nounces “Alternate Intercom Function,” when activated, and “Standard In-
tercom Function” when deactivated.” The alternate intercom mode is an-
nounced at power up, unless the power on announcement has been defeated.
Both the pilot and copilot audio panels can invoke the Alternate
Intercom Function, which applies to BOTH audio panels.
“Monitor” Function
This function turns the Monitor mode on and off.
When the Monitor mode is on, the audio from the COM that is selected for
reception only (only top LED illuminated) will be muted when the radio that
is selected to transmit becomes active.
This function is useful if you are copying weather from AWOS on COM 2,
but have clearance delivery tuned in on COM 1. With the monitor active, the
AWOS audio will be silenced when clearance delivery starts to speak.
To activate the Monitor Function press and hold AUX. The audio will an-
nounce “Monitor on,” when activated, and “Monitor off” when deactivated.
This function applies to each crewmember’s audio panel independently.
NOTE: This mode is NOT remembered through power cycles, to prevent
inadvertent blocking of desired audio on the next trip.
“Music” Distribution Function
In the pilot’s audio panel, the Music function turns the music 1 source
on, or off, with accompanying audio announcement.
In the copilot’s audio panel, the Music Function has three modes for
the copilot and passenger distribution. To cycle Music distribution
modes, press and hold Mute button until the annunciation starts.
When “Music number one, all headsets” is selected, Music 1 (Bluetooth
source, or rear connector) will be distributed to the copilot and passenger headsets
and is independent of the intercom mode switch. Therefore, even in the CREW mode,
the passengers will hear Music 1, although though they will not hear the crew inter-
com or radios.
This mode allows you to use a single in-flight entertainment source. The music mut-
ing follow the selected mode.
When you press “Music” function again, you’ll hear, “Alternate music distribution.”
This function makes Music 2 dependent on the intercom mode.
In this state, Music 2 will be heard only when the intercom is in the CREW mode,
and only the passengers will hear it. Music 1 (Bluetooth, Rear Input, and Front Panel
Jack) will be provided to passengers’ headset in ISO and ALL intercom modes.
Press again, and you will hear “Standard Music Distribution.” In this mode, Music 2
becomes active, and will always be presented to the passengers. Music 1 is only
available to the copilot. The intercom mode switch will not have any affect on the
music distribution.

Page 18 202-890-0304 Rev. 2 PMA8000D Pilot Guide
When the music is in “Standard music distribution,” Music 1 will always go
to the copilot, and is never heard by the passengers. Music 2 is always heard
by the passengers, and never heard by copilot.
This mode is useful if your passengers have a different interest in entertain-
ment or are watching a DVD, but do not want to be excluded from the inter-
com conversations.
Alternate Music distribution modes are announced in copilot headsets at
power up, unless the power on announcement has been defeated.
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, hold the COM 3 and AUX buttons for two seconds. The fea-
ture can be enabled using the same sequence.
Music Muting
There are two SoftMute™ muting circuits. The front panel "Mute" button
has four modes, and controls the Mute function for Music 1.
The SoftMute™ circuit will cut the music out whenever there is conversation
on the radio, the intercom, or both, depending on the “Mute” mode selected.
When that conversation stops, the music returns to the previous level com-
fortably, over a second or so.
The mute mode functions are controlled through sequential pushes of the
Mute button, and include voice annunciations of the mode selected.
Mute On - music will mute with either intercom or radio -
MUTE button is LED lit.
Radio Mute -Radio will mute music, but intercom will not
mute music - MUTE LED is OFF.
Intercom Mute - Radio will not mute music, intercom will
mute music - MUTE LED is OFF.
Mute Off -The “Karaoke” mode - music will not mute except during
radio transmissions.- MUTE button LED is OFF.
When the PMA8000D is turned on, it always begins in “Mute on” mode.
The passengers’ intercom also has a SoftMute™ circuit. If the passengers
hear the radio, or talk on the intercom, the music will mute. If the audio
panel is in CREW mode, then the radio reception will not affect the passen-
ger music.
If the passengers are listening to the music 1 input or front panel input, their
Karaoke Mode is controlled by the front panel “Mute” button.
If the passengers are listening to the music 2 input, their Karaoke Mode is
activated by holding the AUX and MUTE buttons for more than one second.
Music 1 Volume
The music level is set at the factory at a comfortable level. We recommend
adjusting the entertainment volume at the sources. However, the Music 1

volume (rear input only) can be adjusted from the front panel,
if desired, by pressing SPR button.
NOTE: Increasing this music level can increase the amount of
aircraft electrical system noise as well.
Press the Music Volume (SPR)for more than one second, a tone will be
heard indicating the volume level is changing and the music volume will
begin to change. The volume will either increase or decrease, depending on
the last action. To reverse the volume change, release the Music Volume
(SPR) button, and press and hold again, and the volume will change. Con-
tinue to hold until the desired level is reached.
Note: Since it is possible to turn the volume completely off, you may need to
turn the volume up if you don’t hear music when you expected to.
It will take about 10 seconds to go from minimum to maximum volume.
Swap Mode (Switch from COM 1 to COM 2 or COM 3 remotely)
The “swap” button allows you to switch between the COM transmitters
without having to reach up to the audio panel, and is a handy way to switch
to Ground Control when exiting the runway. This optional switch is usually
mounted on the control yoke or a convenient place by the pilot position.
COM 3 can be included in the SWAP rotation if desired. Hold the external
swap button and the COM 3 XMT at the same time to add or remove COM 3
from the Swap function.
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. The system automatically begins to record the instant the radio selected for
transmit becomes active. Only the crewmember will hear the playback audio from
their audio panel.
To play back the last recorded message, you press and hold the COM RCV pushbut-
ton 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 play-
ing, 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, or
when power is removed from the audio panel.
The playback will stop whenever there is more incoming selected com audio, and the
message can be replayed from the beginning. Note: an external playback button may
also be installed in a convenient location.
