English4. Loosen the screws that hold the lamp to the projector. If the screws are not 
loosened completely, they could injure your fingers. It is strongly 
recommended that you use a magnetic-head screwdriver to retain the screw 
should it come loose 
5. 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. To reduce the risk of injuries to fingers and damage to internal 
components, use caution when removing lamp glass that has shattered.
Do not place the lamp in locations where water might splash on it, children 
can reach it, near or above heat sources, or near flammable materials.

touch the optical components inside, it could cause color unevenness and distortion of the projected 
images.

reset the lamp time.
Do not turn the power on with the lamp cover removed. 
Whenever the lamp is replaced, reset the total lamp operation time.
