Projectors - A/V Mute

Pressing the A/V (Audio/Visual) Mute button on the projector remote allows you to turn the sound and image off instantly without powering off your projector.  It is a good idea to use this feature when you want to direct your students’ attention away from the smart board or projection screen for a short period of time.  Press the A/V button a second time to resume the sound and image.  Depending on your projector model, your remote may look different than the image below.
