this lamp in a proper manner.
Step 1. Turn the power off and disconnect the projector from the wall socket.
Step 2. Protect the projectors 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

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.

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.

and tighten the screw firmly.
Loose screw may cause a bad connection, which could result in malfunction.
