the volume. The volume level indicator LED changes colour according to the volume setting; green

Listen Only A single DAK press causes an audio route to be made from the desti-

nation. Used when listening to an external audio signal (not originat-

ing from a Control Panel) is required.

Talk and Listen A single DAK press causes a bi-directional audio route to be made

between the source panel and the destinations. Often used between

panels and external audio signals.

Talk & Forced Listen This is similar to Talk and Listen except that the Listen route is perma-

nently made. The operator need only press the DAK to talk.
