1. On the box (Pictured below) press and hold the power button for 3 seconds (Far Right). The number screen on the box will then turn on. The box is located just under the levels at the top of the audio cabinet.

2. Press the button at the bottom until it goes green.

3. Slide the slider to green - this unmutes the mic. 

To pack it away just press and hold until the screen on the box goes black and hold the now green light on the bottom of the microphone until it goes white.
