Eye Safety Warnings
	
▀■   Avoid staring directly into the projector beam at all times.
▀■   Minimize standing facing into the beam. Keep your back to 
the beam as much as possible.
▀■ A stick or laser pointer is recommended to avoid the need for 
the user to enter the beam. 
▀■ Ensure that projectors are located out of the line of sight from 
the screen to the audience; this ensures that, when presenters 
look at the audience, they do not also have to stare at the pro-
jector lamp. The best way to achieve this is by ceiling-mount-
ing rather than floor or table-mounting the projector.
▀■ When projector is used in a classroom, adequately supervise 
students when they are asked to point out something on the 
screen.
▀■ In order to minimize the lamp power needed, use room blinds 
to reduce ambient light levels.
