Eye Safety Warnings
▀■ Avoid staring directly into the projector’s beam of light at all times.
▀■ Minimize standing facing into the beam. Keep your back to the beam as much as possible.
▀■ Using a stick or laser pointer is recommended to avoid the need  for the presenter 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  
projector lamp. The best way to achieve this is by ceiling-
mounting the projector rather than placing it on floor or table 
top.
▀■ 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.
