FEATURE DESCRIPTION
HANDSET / 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 ( 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 is 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. Any call number may be programmed with the
privilege “simplex always” . When a call is placed from or to a station with the “simplex always”
privilege, the initiator will be in listen mode and the T-button must be used to change the speech
direction.
MICROPHONE CUTOFF
To temporarily mute the microphone during conversation, the mute button may be pressed down.
DIRECT DIALING
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 short DC-
shift (<1 sec). This type of calling is used with door stations and elevator stations that do not have a
tone dialer.
