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 oor or table top.
▀■ When projector is used in a classroom, adequately supervise stu-
dents 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.
