one or more times to select another active input source.

 Be sure the external source is turned on and connected.

For a computer connection, ensure your notebook computer’s external video port is

turned on. Refer to the computer manual.

If the image is out of focus:

 Be sure the lens cover is open.



While displaying the on-screen menu, adjust the focus ring. (The image size should

not change; if it does, you are adjusting the zoom, not the focus.)

Press the

Resync

projector. Use the remote control within the effective range.

 Aim the remote control at the screen or at the front or back of the projector.



Move the remote control so it is more directly in front of or behind the projector and

not as far to the side.
