Use Cases:

Case 1: Normal Live Speech on PTT

When a new access panel is added to a project they will have live speech already preconfigured on the PTT key. This is set up without zones and with priority 21.

Adding a zone select key on a different DAK key will allow this function to be used.

Case 2: Live Speech with Handheld Microphone

Setting the live speech function to Wait for PTT will allow a handheld microphone to be used. Triggering the function will prime the access panel, and the next press on the handheld microphone will start the audio.

Availability

This function is available from Exigo 1.0 and newer.
