sages.
▀■ Warning - Use the “Lamp Reset” function from the on-screen display  “Options|Lamp Settings” menu after replacing the lamp 
module (see page 47).
▀■ Warning - When switching the projector off, please ensure the cool- ing  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.
▀■ Warning - When the lamp is approaching the end of its life, the  message  “Lamp  is  approaching  the  end  of  its  useful 
life” displays on the screen. Please contact your local 
reseller  or  service  center  to  change  the  lamp  as  soon 
as possible.

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 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.
