MAINTENANCE This section describes the simple maintenance procedures you should follow to replace the lamp and clean the filter. Replacing the Lamp After your lamp has been operating for 1500 hours (up to 2000 hours in Eco mode) or longer, the LAMP indicator in the cabinet will blink red and the message will appear. Even though the lamp may still be working, replace it at 1500 (up to 2000 hours in Eco mode) hours to maintain optimal projector performance. CAUTION • DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off, wait 60 seconds, and then unplug the power cable. Allow at least one hour for the lamp to cool before handling. • DO NOT REMOVE ANY SCREWS except the lamp cover screw and the lamp case screw. You could receive an electric shock. • The projector will turn off and go into stand by mode after 1600 (up to 2100 hours in Eco mode) hours of service. If this happens, be sure to replace the lamp. If you continue to use the lamp after 1500 hours (up to 2000 hours in Eco 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 NEC dealer for lamp replacement. To replace the lamp: NOTE: The replacement lamp comes with a flat-blade screwdriver. Use the screwdriver to remove the lamp cover and lamp housing. 1. Loosen the lamp cover screw until the screwdriver goes into a freewheeling condition. Press firmly and slide the lamp cover off.The lamp cover screw is not removable.
