Table 18: PD4226 Pushbutton Attributes
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.
This is similar to Talk and Listen except that the Listen route is perma-
nently made. The operator need only push the key to talk.
