Usage Notice  
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.
