FEATURES DESCRIPTION
HANDSFREE/LOUDSPEAKING
When two intercom stations are connected, either party may speak to the other hands free without
touching any buttons.
CONFIDENTIAL/SOFTSPEAKING
At any time during the call, either one or both parties may pick up their station (AA904 or AA916)
and use it as a handset for a confidential conversation. When both parties are in handset mode, the system
operates in open duplex mode and both parties may talk and listen at the same time.
SIMPLEX
The T-button may be used to control the speech direction (push to talk release to listen). This is useful
when one of the intercom stations are in a noisy area. Either party may use this function. If both stations are
pushing the T-button the control is given to the station that pushed T last. Either party may revert to
handsfree mode by tapping the T-button or touching the side strip on the AA904. Any call number may be
programmed with the privilege “simplex always” . When a call is placed from or to a station with the “sim-
plex always” privilege, the initiator will be in listen mode and the T-button must be used to change the
speech direction.
MICROPHONE CUTOFF
To temporary mute the microphone during conversation, the mute button may be pressed down.
DIRECT DIALLING
It is possible to program keys 0 to 9 of each intercom station’s keypad to speed dial frequently called
numbers. When a programmed key is pressed, a dialtone is heard as normal. If a second key is pressed
within 1.2 seconds (programmable subscriber timer) then a normal dial sequence is taken.
DIRECT ACCESS
It is possible to program one call number for each intercom station to be activated by DC-shift. This
type of calling is used with door stations and elevator stations that do not have a tone dialer.
