There is no sound when I project. What should I do?

• If there is no sound, try the following:

  • Make sure the projector and cart are powered on.
  • Press the A/V Mute button on the projector's remote control to resume video and audio if they were temporarily stopped.
  • Make sure all the cables are securely connected to the cart.
  • Restart the projector.
  • Press the Switch function button on the cart's control panel to select Volume, then select Up to increase the volume.
