Is the lens cover still attached?			Remove the lens cover. sp.31
Is the projector at the correct distance?			The recommended projection distance range of the EMP-821 is 86–1473 cm (2.8–48.3 ft.) and that
			of the EMP-81/61 is 87–1094 cm (2.8–35.9 ft.). Set the projector up so that it is within this range.
			sp.16
Is the keystone adjustment value too large?			Decrease the projection angle to reduce the amount of keystone correction. sp.39
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 approximately one hour before it
			is to be used. If condensation forms on the lens, turn the power off and wait for the condensation to
			disappear.
