•
If the connected DVI digital equipment is turned on before the

not be projected properly or may not be displayed at all. Ensure
that the appropriate input mode has been selected on the
projector before you turn on the connected equipment.

condensation may form on the surface of the lens and the
image will become blurred. Please set up the projector at least
one hour before it is to be used. If condensation should form,
remove the power cord from the wall outlet and wait for it to
clear.
