About lamp replacement

●If the projector is set in a constricted place, attempting to replace the lamp in that place could cause injury. Move the projector to a place large enough to work in.

●To avoid malfunctions, be sure to use only genuine replacement parts. Also, never attempt to re-use an old lamp as this could cause marked performance deterioration or lamp blow-out leading to projector malfunction. In the worse case, broken pieces of glass from the lamp may cause injuries.

●Do not replace the lamp immediately after the projector has been used. The temperature of the lamp unit is still high and could cause a burn. Allow a cooling period of one hour or more before replacement.

●Before starting to replace the lamp, disconnect the power cord from the wall outlet while the STAND BY indicator is on. Replacing a lamp while the power cord is connected could cause injury or electric shocks.
