4. MAINTENANCE
This section describes the simple maintenance procedures you should follow to replace the lamp, clean the filters, and replace the batteries in the remote control.
Replacing the Lamp
After your lamp has been operating for 1000 hours (up to 2000 hours in Eco 2 mode and up to 1500 hours in Eco 1 mode) or longer, the “Status” light in the cabinet will go on and the mes- sage will appear. Even though the lamp may still be working, replace it at 1000 (up to 2000 hours in Eco 2 mode and up to 1500 hours in Eco 1 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 disconnect 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 two lamp case screws. You could re- ceive an electric shock.
•The projector will turn off and go into stand by mode after 1100 (up to 2100 hours in Eco 2 mode and up to 1600 hours in Eco 1 mode) hours of service. If this happens, be sure to replace the lamp. If you continue to use the lamp after 1100 hours (up to 2100 hours in Eco 2 mode and up to 1600 hours in Eco 1 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 hap- pens, contact your NEC dealer for lamp replacement.
To replace the lamp:
1.Loosen the lamp cover screw until the screwdriver goes into a freewheeling condition and remove the lamp cover. The lamp cover screw is not removable.
2.Loosen the two screws securing the lamp housing until the screwdriver goes into a freewheeling condition. The two screws are not removable.
Remove the lamp housing by pulling out the handle.
NOTE: There is an interlock on this case to prevent the risk of electrical shock. Do not attempt to circumvent this inter- lock.

Be sure to tighten the screws.
4.Reattach the lamp cover.
