I see the message No Signal. What should I do?

• An image source not connected to the projector is selected, the signal is not being output from the computer, or the signal is not reaching the projector. Make sure the connectors are securely attached to both the projector and the image source. Then check that the image source is selected correctly. If your projector is attached to a Macintosh, make sure that the dip switches on your Macintosh desktop adapter are set correctly. When NO SIGNAL is displayed, you cannot access the Video menu, except for auto on or off.
