Questions and answers

The PC image appears on the computer monitor, but not on the projection screen. What is wrong?

Make sure that the data projector is definitely powered on and that you have  allowed it time to warm up. Is light coming from the lens? 

Consult the room instructions to ensure that the projector is switched to the correct source - for example Data or PC.

Many units have an  Projector Mute or Image blank option on the Extron control panel, check that this option is not on.

If neither of these resolve the problem, please call ITS AV Support on ext 8022 for assistance.
