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.
