    Lamp Information
    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.
    Status LED Indicators
    Lamp Exceed Service Hours —
     When this LED lights red continuously, it is 
    warning you that the lamp has exceeded 1500 
    service hours. Replace the 
    projection lamp immediately.
    CHANGE THE LAMP, AND RESET THE LAMP TIMER —
     The lamp has been in 
    operation for 1200 hours.
    CHANGE THE LAMP, THE POWER WILL TURN OFF AFTER 20 HOURS —
     The 
    lamp has been in operation for 1479 hours, and the power will turn off after 20 more 
    hours.
    CHANGE THE LAMP! —
     The lamp has been in operation for over 1500 hours, and 
    the power will turn off automatically in 10 minutes.
    All of these messages will not display for more than 3 minutes, but each message 
    will be displayed whenever you turn on the lamp again.
    Lamp is not well attached —
     When the LED blinks rapidly, it indicates that the 
    lamp is not attached properly.
    Temperature is too high —
     When the projector’s internal temperature is too hot to 
    operate safely, the LED blinks slowly for one minute and the lamp turns off 
    automatically.
    If the LED light is off, it means that the projector’s lamp and temperature are 
    operating under normal conditions.
    Caution
    The LAMP indicator will light if the lamp becomes too hot. Turn off the power and let 
    the projector cool for 45 minutes. Turn the power back on. If the LAMP indicator still 
    lights red, please contact your dealer.

    Lamp Replacement
    Caution
    To reduce the risk of electrical shock, always turn off the projector and disconnect 
    the power cord before changing the lamp.
    1. Press the POWER 
    button to turn the main power switch off and disconnect the 
    power cord from the outlet.
    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 indicated by the arrows below. (It is strongly recommended 
    to use a magnetic-headed screwdriver, if possible. Pull the handle to remove the 
    lamp housing. If the screws are not loosened completely, they could damage 
    your fingers. Do not insert your hand into the box after the lamp is removed. If 
    you touch the optical parts inside, it could cause color unevenness, etc.
    4. Replace the lamp with the new one, insert it in the projector, and tighten the 
    screws. Firmly tighten the lamp screws. Loose screws may cause a bad 
    connection, which may result in a 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 has been replaced, reset the total 
    operation time of the lamp. Do not reset if the lamp was not replaced, as this 
    could cause breakage.
