How it works:

When the microphone senses that sounds have reached a preset threshold volume level, the built-in Variable Control Voice Actuator (VCVA) starts recording automatically, and stops recording when the volume drops below the threshold level.   

1)  Press and hold the MENU/SET button for 1 second or longer. The main menu opens  

2) Press the up or down button to choose "VCVA".  

3) Press the MENU/SET button. The VCVA setup process begins.  

4) Press the up or down button to choose between "ON" and "OFF" 

ON: Will start recording in VCVA mode.
OFF: Will resume recording in normal mode.  

5) Press the MENU/SET button to complete the setup screen.  

6) Press the STOP button to close the main menu.
When "ON" is selected, a VCVA indication will be displayed on the screen.
