Use and Replacement of Lamp

The projector lamp has a normal operating time of approximately 1200 to 1500 hours, called the lamp life. During the normal lamp life, the picture will be bright and the colors clear. If the lamp is used beyond the normal lamp life, the picture will become dark and the colors poor. Always replace lamps with new ones. Using an old lamp in the projector could cause a malfunction. When the power is turned on, the LAMP indicator will light up red or a message will be displayed to indicate when it is time to replace the lamp. Consult your dealer.
