BenQ PB8120, PB8230, PB8220 user manual

1.Turn off the projector. Disconnect the power cord from the outlet and the projector.

2.Loosen the screw and remove the lamp cover. If the lamp is hot, avoid burns by waiting 45 minutes until the lamp has cooled.

3.Loosen the 3 screws. (It is strongly recommended that you use a mag- netic-head screwdriver.) Pull the handle to remove the lamp housing. If the screws are not loosened com- pletely, they could injure your fin- gers. Do not insert your hand into the box after the lamp is removed. If you touch the optical components inside, this could cause color unevenness in projected images.

4.Replace the lamp with a new one. Insert it into the projector, and tighten the screws firmly. Loose screws may cause a bad connection, which may result in malfunction.

5.Re-install the lamp cover and tighten the screw. Do not turn on the power with the lamp cover removed. Whenever the lamp is replaced, reset the total lamp opera- tion time. Do not reset if the lamp is not replaced as this could cause damage.
