Maintenance 31
Step 1. Turn the power off and disconnect the projector from the wall socket.
Step 2. Turn the projector over. Then loosen the
screws and remove the lamp cover. If
the lamp is hot, avoid burns by waiting
for 45 minutes until the lamp has
cooled.

the projector. If the screw is not loos-
ened completely, they could injure your
fingers. It is strongly recommended that
you use a magnetic-head screwdriver.
Step 4. 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.
Do not place the lamp in locations where water
might splash on it, children can reach it, or near
flammable materials.
Do not insert your hands into the projector after the lamp is removed. If you touch the optical
components inside, it could cause color unevenness and distortion of the projected images.
Step 5. Insert a new lamp. Make sure the handle
is fully locked and tighten the screw
firmly.

could result in malfunction.
Do not over tighten the screw.
Step 6. Re-install the lamp cover and tighten the
screw. Do not turn the power on with
the lamp cover removed. Whenever the
lamp is replaced, reset the total lamp
