allowing the crew to focus on the radio. The passengers will still be able to talk to each other. Pressing
TEL button again switches the intercom back to “Standard Intercom Function.”
Alternate Intercom mode is announced at power up, unless the power on announcement has been defeated.
3.11.2 Monitor (B)
Pressing Monitor (AUX) will activate or deactivate the COM radio monitor function. When the Monitor 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, until audio announces “Monitor on,” and the same
button again to deactivate. The unit announces“Monitor off” when deactivated.
NOTE: This mode is NOT remembered through power cycles, to prevent inadvertent blocking of desired
audio on your next trip.
3.11.3 Music (C)
The Music function button (C) allows you either send the music 1 input to all intercom stations, all of the
time, or have other distribution rules apply to your music inputs.
When “Music one all headsets” is selected (press and hold Mute), music 1 (from the rear connector input,
Pins J2 23 & 24 only) will be distributed to all headsets and is independent of the intercom mode switch.
Therefore, even in the CREW mode, the passengers will hear Music 1, even though they will not hear the
intercom or radios.
This mode allows you to use a single in-flight entertainment source aboard, and to send it everywhere, even
in crew mode. The music muting will be normal, and follow the selected mode of the crew or passengers.
Music function also allows you to configure your music to be either independent of the intercom mode, or
to make Music 2 dependent on the intercom mode.
When you press and hold Music (Mute) again, you’ll hear, “Alternate Music distribution.” In this case,
Music 2 will be active only when the intercom is in the CREW mode, and only the passengers will hear it.
This distribution is similar to other brands of audio panels. It allows the passengers to have their music
source come on only when they are not hearing the crew. In addition, the front panel jack input will be dis-
tributed to the passengers in ALL and ISO mode.
Press and hold Music (Mute) again, and you will hear “Standard Music Distribution.” In this mode, Music
2 becomes active, and will always be presented to the passengers on the intercom. Music 1 is only available
to the pilot and copilot. The intercom mode switch doesn’t have any affect on the music distribution.
When the music is standard, Music 1 will always go to the pilot and copilot positions, and is never heard by
the passengers. Music 2 is always heard by the passengers, and never heard by the pilot and copilot.
This mode is useful if your passengers have a different interest in entertainment or are watching a DVD, but
do not want to be excluded from the intercom conversations.
The pilot and copilot will always hear Music 1 through the unit rear connector, or a source plugged into the
front panel jack. This is present in ALL and CREW intercom modes, and available to the copilot position in
ISO mode.
The pilot can hear this music source in ISO mode, if desired, as follows: In the ISO mode, hold the (Music)
button, and press the ICS mode button for more than one second. The ICS mode LED will blink slowly to
indicate music is connected to the pilot headset, although the intercom is not.
Music 2 is provided to the passenger positions regardless of intercom mode, when the audio panel is in
Standard Music Distribution, and also in Alternate Music Distribution, but only if the intercom is in the
CREW mode. The pilot and copilot can never hear Music 2, under any condition.
