Lamp replacement / Maintenance

The lamp is designed to project the image on the LCD
panels. When the lamp no longer functions, replace it
with a new one.
Caution:
• Do not remove the lamp immediately after using
the projector. You may get burned because the
lamp is very hot after use.
• Before replacing the lamp, press the POWER
button to turn off the lamp and wait for two
minutes for the lamp and LCD panels to cool
down. Unplug the power cord from the wall outlet
and wait one hour for the lamp to cool down
completely.
• Do not remove the lamp except for replacement.
Careless handling can cause injury or fire.
• Do not touch the lamp directly. It may break and
cause injury or burn.
• Be sure not to drop the lamp lid screw into the
projector. Also be sure not to put metal or any
flammable objects inside because it may cause fire
or electric shock. If any objects should fall inside,
unplug and contact your dealer.
• Install the lamp securely to prevent failure and
fire.
• If the lamp should break, small glass fragments
may fall out through the grilles and some may
remain inside of the projector or the lamp box.
When taking the lamp box out, be sure to turn
over the projector and hold the handle of the lamp
box to avoid injury due to the glass fragments.

box or hold it in front of your face after removing
it. The glass fragments may fall out and cause
injury to your eyes.
