When this projector is brought into a warm room from a cold outdoor, condensation can
take place on the projection lens and mirror inside, blurring the screen and reducing your eyesight,
but do not worry. The condensation will disappear and the screen will return to a normal condition
no sooner than the projector acclimates to the surrounding temperature.
