USAGE NOTICE

■

  

 

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.

■

  

 

Use of a stick or laser pointer to avoid the need for the user to 

enter the beam is recommended. 

■

  

 

Ensure that projectors are located out of the sight line from the 

screen to the audience; this ensures that, when presenters look 

at the audience, they do not also have to stare at the projec-

tor lamp. The best way to achieve this is by ceiling-mounting 

rather than floor 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 to project a 

visible presentation, use room blinds to reduce ambient light 

levels.
