This button-press allows the radio-user to activate and deactivate the Public Address (PA) system, which routes microphone audio through an external speaker system. This feature is available on a radio-wide basis.

In addition to this programmable button selection, the O9 Control Head has a dedicated "Public Address" button.

If the Public Address and DotRed.png Siren options are both on at the same time, pressing the PTT button overrides any Siren function. Any Siren tone or incoming radio signals (if in External Radio mode) is abruptly muted to give the Public Address priority operation.
