Replacing the Projection Lamp
CAUTION:
•Potential hazard of glass particles if lamp has ruptured. Please have Sharp Authorized LCD Projector Dealer or Service Center replace lamp if rupture occurs.
•Do not remove the lamp cage directly after operation of the projector. The lamp may be extremely hot. Wait at least one hour after the power cord is disconnected to allow the surface of the lamp cage to fully cool before removing the lamp cage.
The rated lamp life is about 1000 hours. The rated lamp life is the average life of the lamps produced and tested (under the test conditions of our company). However, it may become shorter depending on the conditions of usage.
After the lamp has been operating for 1000 hours or longer, the STATUS indicator on the control panel will light and the “LAMP USAGE” icon which shows hours of total lamp usage will be displayed on the screen. When this happens, turn off the unit and replace the lamp cage with a new one. The unit will not turn on after 1100 hours. (It will go off if it is in use.)
