==Configure the group to use "Automatic M-key"==
In AlphaPro, select the Group Call, and enable "Automatic M-key". When enabled, there is no need to press the M-key to open the microphone during the group call:

== DAK event ==
In the [[Event Handler]], the event 30 (Station Input or Station DAK key) is triggered when a DAK Key is pressed.

In [[AlphaPro]], press '''Users & Stations''' button, select a station from the listbox, and press '''Events'''. '''Insert''' a new event with the following properties:
