(1) (2) NAV1 - FM2 Receive Select Switches and Legends
Each User has four white two-position centre-off toggle
switches for the NAV1/COM1 to DME/FM2
receivers/transceivers. When a left or right switch is set
to the 'up' position, audio from the receiver associated
with the legend above the switch is routed to the phones
of that side's user (and passengers if configured.) In the
'down' position, audio from the transceiver associated
with the legend below the switch is routed to the phones
of that side's user (and passengers if configured.)
The backlit legends are interchangeable to allow
customization. The default legends are NAV1, NAV2,
ADF and DME above the switches, and COM1, COM2,
FM1 and FM2 below the switches.
(3) AUX and PA Receive Select Switches and Legends
The AUX/PA switches are two white two-position centre-off
toggle switches. The left-hand switch is associated with the Left
User, and the right-hand switch is for the Right User.
Installation and Operating Manual
To select AUX, the appropriate switch is set to the 'up' position,
and for PA it is in the 'down' position. Audio from the associated
receiver is routed to the phones of that side’s user (and
passengers if configured).
The backlit legends are interchangeable to allow customization.
The default legends are AUX above the switches and PA below
the switches.
(4) VOX Threshold Control
The VOX Threshold Control is an unlit rotary knob in the
centre top of the panel that is used to set the VOX
threshold level of the unit for all users and passengers.
When rotated fully clockwise (cw), the threshold will be
at maximum, VOX ICS operation is disabled and ICS
PTT input is required for ICS operation.
When rotated fully counterclockwise (ccw), the threshold
will be at minimum (almost live).
To adjust the unit for VOX (Voice activated) use, the
VOX control should be set fully ccw and then slowly
rotated cw to the point where no intercom audio can be
heard. The VOX control may require adjustment for
proper operation as ambient noise changes.

eft User Controls (11) TX Annunciators (12) Right User Controls
The Right User TX selector is an unlit rotary seven-position knob that is used to select transmission for one of the six
transceivers, or the RMT (remote) position. Below the knob is a 'TX' deadfront annunciator (12) which will illuminate
during transmission. For Remote operation, refer to section 3.3.11.
Each of the transmit selector positions is linked by a white line to the corresponding
transceiver switch and legend, and each transceiver has a transmit select annunciator
pointing to the associated switch or legend. The appropriate annunciator will light green to
show which transceiver is selected for transmit (right user PA in the example above).
T
he Left User TX selector is an unlit rotary
seven-position knob that operates in the
same manner as the Right User selector,
except that position 7, marked PULL TO
TURN (extreme ccw) is used to select
Emergency (EMER) mode.
Below the knob is a 'TX' deadfront
annunciator (11) which will illuminate during
transmission.
For full information on Emergency mode see
section 3.4.
Note: To prevent accidental selection of Emergency mode, the knob must be pulled towards the user before
it can be rotated to the EMER position.

3.3 Normal Operation Mode
The JA94-N44A is in Normal mode unless EMER mode has been selected via the Left User TX control, or if the
power input is off.
Note: Numbers in parentheses refer to the front panel controls shown in section 3.2.
3.3.1 Panel Lighting
The JA94-N01A NVIS Type I Class B compliant legends and annunciators will be illuminated (when appropriate) and
dim through the aircraft lighting buss.
3.3.2 Receiving
When the JA94-N44A receives an incoming transmission on a transceiver or receiver that has been selected, either
by the white transceiver receive switches (1) (2) or (3) or a transmit selector (5) or (8), the incoming audio will be
directed to the user’s phones.
The audio level of any incoming transmission will depend upon the level selected by the user's front panel RX volume
control – (7) or (10). It will be muted if the unit is transmitting and muting of receive audio during transmit is enabled.
ProCS™ can be configured to route no receive audio, Right User receive audio, or Left User receive audio to
passengers.

Installation and Operating Manual
3.3.3 Transmitting (Transmit Operation)
To select a transceiver, rotate the Transmit Select Switch (5) or (8) until it aligns with the line leading to the
Transceiver Select switch legend (1) (2) or (3) - default legends COM1, COM2, FM1, FM2, AUX or PA. The
corresponding Transmit Select annunciator will illuminate green.
When the user’s TX PTT is activated, the unit will transmit on the selected transceiver, and the deadfront Transmit
Annunciator will illuminate ‘TX’. All MIC and sidetone audio will be routed to the user’s phones, and any music (and
RX and/or ICS audio if selected by ProCS™) will be muted for the duration of the transmission.
Passengers 1, 2 and 6 (designated at installation) will transmit on the radio selected by either the Right User or Left
User, as configured by ProCS™.
3.3.3.1 Simulcast Operation
Note: It is important to be aware of the Simulcast configuration of the aircraft.
The ProCS™ configuration program allows the selection of Simulcast Mode. This can be for the left user or the right
user or both, and for each user the simulcast radio selections can be selected separately.
If simulcast has been enabled via ProCS™ and the user's Transmit Selector Switch is set to PA (simulcast position),
the user will transmit on multiple radios as configured by ProCS™.
3.3.3.2 Transmit Timeout Operation
Note: It is important to be aware of the Transmit Timeout configuration of the aircraft.
The ProCS™ configuration program allows the selection of Transmit Timeout. If selected, transmissions will timeout
after 90 seconds.
3.3.3.3 FM2 PTT Operation
Note: If the FM2 transceiver has been configured as duplex, it can be used with a cellphone or
sat-phone. Check your configuration with the installing agency.
If the unit has been configured for cellphone or sat-phone use and FM2 has been selected for transmit, momentarily
activating the TX PTT (either from the faceplate or by some other method) will keep FM2 transmitting. A second
momentary activation of the TX PTT, or moving the Transmit Selector away from FM2, will stop FM2 from
transmitting.
3.3.4 VOX Operation
A user’s MIC audio is routed to the ICS when the MIC audio level exceeds the VOX threshold (3).
A user’s MIC audio is disconnected from the ICS when the MIC audio level falls below the VOX threshold for 0.5 to 2
seconds.
3.3.5 ICS Operation
ICS audio is the sum of all the MIC audio from users with ICS KEY active or with MIC audio level exceeding the VOX
Threshold level.
The ICS audio also includes the audio input on the ICS TIE from other audio controllers.
The ICS audio is output on the phones of each user.
The ICS audio is muted during transmit as configured by ProCS™.
The ICS audio level at the phones is controlled by the ICS volume control (7) or (10).
Note: If Legacy Passenger ICS Mode has been selected, the Passenger Mics are controlled by the VOX
control until the fully cw (PTT) position is reached. Then the Passenger Mics are automatically set to the
minimum VOX level and should be controlled by in-line PTT drop-cords.

Installation and Operating Manual
3.3.6 ICS Isolation Operation
Note: It is important to be aware of the ICS Isolation configuration of the aircraft.
When the external control signal ICS ISOLATE is active: the LEFT or RIGHT User, as configured by ProCS™, are
isolated from the ICS signal of the passengers and the other User; when configured as both the LEFT and RIGHT
user, the LEFT and RIGHT Users will be connected to each other via an ICS but are isolated from the Passengers
ICS.
In Isolate Mode, the selected user's MIC audio input is disconnected from the ICS TIE output, the user's phones are
disconnected from the ICS TIE input circuit, and the music to the user’s PHN output will be muted.
3.3.7 Direct Audio Operation
DIRECT AUDIO 1 and, when configured by ProCS™, the DIRECT AUDIO 2 & 3, are routed to the LEFT USER
Phones.
DIRECT AUDIO 2 and, when configured by ProCS™, the DIRECT AUDIO 1 & 3 are routed to the RIGHT USER
Phones.
3.3.8 Music Operation
Music to the phones will be muted by incoming audio (ICS, Receive, or Direct Audio) or if the unit is transmitting.
When the incoming audio has ended, the music will gradually return to the previous level.
3.3.9 Rear Hand Mic Operation
When configured by ProCS™, the Rear Hand MIC audio and PTT signal are connected to the Transceiver as
selected by the left or right TX Select switch. The Rear Hand MIC is assigned to left or right user's controls by
ProCS™ in the Passenger and Rear Hand MIC settings.
3.3.10 Cockpit Voice Recorder (CVR) Operation
The RIGHT CVR output consists of the sum of the RIGHT USER MIC input (independent from VOX control setting)
and the RIGHT USER PHONE output, and the LEFT CVR output is the sum of the LEFT USER MIC input
(independent from VOX control setting) and the LEFT USER PHONE output.
3.3.11 Remote RMT Operation
A remote transmit selector may be linked to the JA94-N44A to allow remote selection for transmission via the right
user controls. (This remote selector could be on the right user's cyclic control.) When a remote transmit selector is
installed and the RIGHT USER TX SELECT switch is in the RMT position, then the RIGHT USER will transmit on the
radio or radios as selected by the remote transmit selector.
Note: It is important to be aware of the Remote Operation configuration of the aircraft.

in multiple different configurations with only minimal changes.
The internal circuitry ensures that, although the legends are individually
illuminated, the illumination is consistent and uniform throughout all legends, and
never needs to be balanced. This means that if it is a requirement to change the
labelling due to damage or for a different project, there is no need for costly and
time-consuming illumination checks.

Legend Replacement
To replace a legend, align the text correctly, and then apply gentle pressure until the body of the legend support seats
firmly into the faceplate.
Once the new legend is in place, ensure that it has seated correctly by checking that it illuminates. The unit is now
ready for use.
