control to adjust the focus.

Is the projector at the correct distance?

Setup within the recommended range.

s

Has condensation formed on the lens?

If the projector is suddenly taken from a cold environment to a warm environment, or if sudden ambient temperature
changes occur, condensation may form on the surface of the lens, and this may cause the images to appear fuzzy. Set the
projector up in the room about one hour before it is used. If condensation forms on the lens, turn the projector off and
wait for the condensation to disappear.

Are you using the optional short throw zoom lens (ELPLU02)?

Set the Lens Type to ELPLU02 in the Extended menu.
