Selected FAQ

Q:
Why isn't there any sound?
A:
Check that the volume setting is not turned all the way down and that the audio/visual cable is securely attached to both the projector and the audio source. Make sure the A/V Mute feature is not enabled. If it is, press the A/V Mute button one time to deactivate it. Additionally, if there is still no sound, try connecting the speaker to the computer or video device to make sure that sound from the device is working. Always turn off equipment prior to changing cables.
