Dynamic group call

Operation

• Press a dedicated "Group Configuration" DAK key. The red led in key starts flashing, and the Dynamic Group is emptied.
• Select stations or local groups to be included by pressing the associated DAK keys. A steady green led in the keys indicates that the stations/groups are included
• Press the "Group Configuration" button again, and the group call is activated (the ding-dong chime is played). Pressing the `M`-key opens the microphone.
• The green leds continue to be lit during the group call
• Cancel the group call by pressing the `C`-key. The green LEDs are turned off.

One can only include, not remove, stations/group into the dynamic group. If a worng selection is make, press the C-key, and start the selection over again.

For best performance it is recommended to use CRM V station or ECPIR-3P panel, as these devices have buttons with LEDs showing status.

"Group Configuration" button

• Each operator station is assigned its own Dynamic Group Call by entering the directory number of the Dynamic Group Call in the User Defined Parameter (%1.EXP) field of the operator.
• Include operator stations in UDP group 1. Name the UDP group e.g. "Operators".

Include the operator station in UDP Group 1, and enter the directory number of the Dynamic Group used by this operator (Here: 899)
