To reduce the risk of injuries to fingers and/or compromising image quality by touching the
lens, do not touch the empty lamp compartment when the lamp is removed.
This lamp contains mercury. Consult your local hazardous waste regulations and dispose of
this lamp in the proper manner.
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.
Step 3. Loosen the screw that fixes the lamp to the
projector. If the screw is not loosened
completely, you could injure your fin-
gers. 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 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 com-
ponents inside, it could cause color unevenness and distortion of the projected images.
Step 5. Insert the new lamp. Make sure the handle is fully locked and tighten the screw
firmly.
A Loose screw may cause a bad connection, which 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 operation
timer. Do not reset if the lamp is not
replaced as this could cause damage.
