To initiate recording by acoustic start, the microphone should be armed. To arm a microphone, select it in the microphone list and click .
If the sound level when arming a microphone is lower that the threshold acoustic start level, the microphone indicator becomes yellow.
If the sound level at the time of arming (or any other time after the microphone has been armed) exceeds the threshold acoustic start level, the recording starts and the microphone status indicator becomes red.
The recording will continue as long as the microphone sound level is above the threshold acoustic start level. If the microphone sound level decreases below the threshold acoustic start level, the recording stops and the microphone status indicator becomes yellow.
To disarm the microphone and stop recording, press the button.
The buttons control recordings through the microphone, initiated both by the Operator's command and by acoustic start. Selection of the recording mode depends on the program settings.
