3. DIGITAL ANNOUNCEMENT AND BOARDING MUSIC SYSTEM <0035>
The announcement and boarding music system is a source of voice messages and music
for the passenger address system. The digital boarding music unit is located in the top of the
forward wardrobe. The unit is energized by pressing and releasing the momentary action
ON key. During power up, the system performs a self test that checks the system
components and data file integrity.
System configuration, messages and music are contained in a memory card installed in the
unit. The flight crew can not access the card.
Pressing the language/volume key, labeled L/V, activates the language selection mode. The
up and down arrows and the SEL (select) key may then be used to select up to four
languages. The order of selection is the order that the languages will play.
The liquid crystal display (LCD) lists the languages as they are selected. When in play
mode, the active (cued) language will be highlighted. If the flight attendant activates a
message, the SEL key is inhibited for the duration of the message.
After pressing the A (announcement) key, the up and down arrows and the PLAY key may
be used to scroll up and down the list of available message and music files and select a
particular group of messages to be played.
The selected message or music group name will appear on the LCD and the first cued up
message will be highlighted. Music can be selected by scrolling through the displayed titles
and pressing the SEL key. The PLAY key will cause the highlighted file, message or music,
to be broadcasted. When no music is selected for three minutes, the system defaults to
announcement mode.
In play mode, selecting the L/V key will allow the user to adjust the volume of the broadcast
by pressing the up and down arrows. The broadcast can be interrupted by pressing STOP.
A signal from the PSEU (oxygen deployment at cabin altitude greater than 10,000 feet) keys
up to three prepared messages. These messages supercede all other system outputs. The
music system is, also, muted when a crew member makes an announcement using the
passenger address system.
Control Panel Function Keys:
S ON -- Turns the system ON and OFF
S STOP -- Stops the broadcast
S PLAY -- Plays the announcement or music
S A -- Announcement, used to enter the Announcement Menu
S L/V -- Language/volume used to select the Language Menu or adjust volume
