PA ANNOUNCEMENT FROM ADDITIONAL CABIN EQUIPMENT
Optionally an additional hand-microphone can be installed in the FWD area of
the cabin. This hand-mike has only restricted capabilities (DIRECT PA).
PA FUNCTIONAL AND SOURCE PRIORITIES
The PA functions and sources have different priorities.
FUNCTIONAL PRIORITIES
The PA function with the higher priority overrides the function with the lower
priority.
The priority levels are given in the following table:
LEVEL FUNCTION
1 Direct PA + PA from AMU
2 All remaining PA functions
Note: Level 1 has the highest and level 2 the lowest priority.
SOURCE PRIORITIES
A PA source with a higher priority interrupts a PA announcement from a source
with a lower priority. Only the announcement from the source with the higher
priority is heard.
The sources have the following priority levels:
LEVEL SOURCE
1 Boom Set, Oxygen Mask (AMU)
2 Cockpit Handset (HS)
3 Purser Handset (HS)
4 Attendant Handset (HS)
5 Prerecorded Announcement (PRAM)

LEVEL SOURCE

7 Video or Entertainment Sounds (VCU)
8 Boarding Music
Note: If the purser handset is not assigned (optional), it will have the same
priority level as an attendant handset.
Level 1 has the highest and level 8 the lowest priority with the exception
that an announcement coming from a source of a lower priority has a
higher functional priority.
PA SETTINGS
It is possible to cancel selected and initiated functions manually.
Furthermore the PA system adjusts the volume function in some cases
automatically.
RESET OF SELECTED PA FUNCTIONS
Hooking the handset to the cradle or pushing the RESET button on the handset
cancels a PA function initiated by the handsets functional keys.
If a function is initiated by pushing the PTT button, the release of this button
cancels the function.
VOLUME ADJUSTMENT
In the case of LOW CABIN-PRESSURE or ENGINE ON the volume of a PA
announcement increases automatically. This happens also in the case of a data
bus failure.
To avoid a feedback the volume of the PA announcement in the area around the
respective handset decreases automatically.
For the same reason the volume in the area of the cockpit door decreases if the
cockpit door is opened during an announcement.
