This lamp contains mercury. Consult your local hazardous waste regulations to dispose of this lamp in a proper
manner.
1. Turn the power off and disconnect the projector from the wall socket.
Turn off all connected equipment and disconnect all other cables.
2. After it has cooled down, turn the projector over. Then loosen the
screws and remove the lamp cover as indicated in the picture.
3. Move the latch to another end as shown in the picture.

not loosened completely, they could injure your fingers. It is strongly
recommended that you use a magnetic-head screwdriver to retain the
screw should it come loose.
5. Lift the handle so that it stands up. Use the handle to slowly pull the
lamp out of the projector.
Pulling it too quickly may cause the lamp to break and scatter broken glass in
the projector. To reduce the risk of injuries to fingers and damage to internal
components, use caution when removing lamp glass that has shattered.
Do not place the lamp in locations where water might splash on it, children can
reach it, near or above heat sources, or near flammable materials.

touch the optical components inside, it could cause color unevenness and distortion of the projected images.

latch back, and tighten the screw firmly.
Loose screw may cause a bad connection, which could result in
malfunction.
Do not over tighten the screw.
