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 pro-
jector lamp. The best way to achieve this is by ceiling-mount-
ing the projector rather than placing it on oor 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.
