Usage Notice

Eye Safety Warnings

▀■ Avoid staring directly into the projector beam at all times.
▀■ Minimize standing facing into the beam. Keep your back to

the beam as much as possible.

▀■ A stick or laser pointer is recommended to avoid the need for

the user 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-mount-

ing rather than oor or table-mounting the projector.

▀■ 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.
