messages.
▀■Warning - Use the “Lamp Reset” function from the on-screen display
“Options|Lamp Setting” menu after replacing the lamp
module (see page 53).
▀■Warning - When switching the projector off, please ensure the
cooling cycle has been completed before disconnecting
the power. Allow 90 seconds for the projector to cool
down.
▀■Warning - Do not use the lens cap when projector is in operation.

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.
