Precautions
Please follow all warnings, precautions and main-
tenance as recommended in this user’s guide.
▀■ Warning - Do not look into the projector’s lens when the lamp is 
on. The bright light may damage your eyes.
▀■ Warning - To reduce the risk of fire or electric shock, do not ex-
pose this projector to rain or moisture.
▀■ Warning - Please do not open or disassemble the projector as this 
may cause electric shock.
▀■ Warning - When replacing the lamp, please allow unit to cool down, 
and follow all replacement instructions. See page 50.
▀■ Warning - This projector will detect the life of the lamp itself. Please 
be sure to change the lamp when it shows warning mes-
sages.
▀■ Warning - Use the “Lamp Reset” function from the on-screen display 
“Options|Lamp Settings” menu after replacing the lamp 
module (see page 44).
▀■ 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.
▀■ Warning - To reduce the risk of injury to the eyes, do not look directly 
into the laser beam on the remote control and do not point 
the laser beam into anyone’s eyes. This remote control is 
equipped with a Class II laser that emits radiation.
When the lamp reaches the end of its life, the pro-jector will not turn back on until the lamp module has been replaced. To replace the lamp, follow the procedures listed under “Replacing the Lamp” section on pages 50 
- 51.

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.
