SPEAKER BUTTON
Selecting this button places the radio audio that is selected by the
pilot over the cockpit speaker.
The button turns green when the speaker function is active.
If the SPKR button is held for more than 1 second, the unit enters
the Public Announcement (PA) Mode. In PA mode, the pilots mic
audio is passed over the cockpit speaker, and to all the headsets
(assuming the intercom is in ALL mode) when the pilot presses
the PTT. The co-pilot can transmit over the selected radio in PA
mode.
When in PA mode, the SPKR button will flash green.
To exit PA mode, press and hold the SPKR button for greater
than one second.
