Page 35

This lamp contains mercury. Consult your local hazardous waste regulations to dispose of this lamp in a proper manner.

Step 1. Turn the power off and disconnect the projector from the wall socket.

Step 2. Protect the projector's surface by clearing a flat open area on your desk and placing a soft item on the desk for padding.

Step 3. 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 4. Loosen the screw fixing the lamp to the projector. If the screw is not loosened completely, the lamp cannot be removed. Be careful not to lose the screw as it is needed to hold the replacement lamp in place. It is strongly recommended that you use a magnetic-head screwdriver.

Step 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.

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 6. Insert a new lamp. Ensure the handle is fully laid flat and locked in place. Reinsert and tighten the screw firmly.

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

Step 7. Reinstall the lamp cover and tighten the screws.

Step 8. Restart the projector.

Do not turn the power on with the lamp cover removed.
