Replacing the Lamp

After your lamp has been operating for 2000* hours (up to 3000* hours in Quiet mode) or longer, the LAMP indicator in the cabinet will blink red and the message “Replace with the new lamp.” will appear. Even though the lamp may still be working, replace it at 2000* (up to 3000* hours in Quiet mode) hours to maintain optimal projector performance. After replacing the lamp, be sure to clear the lamp counter. See page 47.

CAUTION

•DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off, wait 30 seconds, turn off the main power switch and then disconnect the power cord. Allow at least one hour for the lamp to cool before handling.

•DO NOT REMOVE ANY SCREWS except two lamp case screws. You could receive an electric shock.

•Do not break the glass on the lamp housing.

Keep finger prints off the glass surface on the lamp housing. Leaving finger prints in the glass surface might cause an unwanted shadow and poor picture quality.

•The projector will turn off and go into standby mode after 2100* (up to 3100* hours in Quiet mode) hours of service. If this happens, be sure to replace the lamp. If you continue to use the lamp after 2000* hours (up to 3000* hours in Quiet mode) of use, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp case. Do not touch them as the pieces of glass may cause injury. If this happens, contact your dealer for lamp replacement.

*NOTE: The projector will turn off and go into standby mode after 2100 (up to 3100 hours in Quiet mode) hours of service. A lamp may burn out before the LAMP indicator blinks.
