SPEAKER
All of the radios can be heard over the cabin speaker. Pressing the SPKR Key selects and deselects the cabin speaker. Speaker audio is muted when the PTT is pressed. Certain aural alerts and warnings (autopilot, traffic, altitude) are always heard on the speaker, even when the speaker is not selected.
