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 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 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.
