This section describes the simple maintenance procedures you should follow to replace the lamp, clean or replace the filter, and replace the batteries in the remote control.

Replacing The Lamp

After your lamp has been operating for 2000 hours or longer, the red “status” light in the cabinet will go on and the lamp icon will appear on the above right of the screen whenever the projector is turned on. The lamp icon remains on after 2100 hours of service. Even though the lamp may still be working, replace it at 2000 hours to maintain optimal projec- tor performance.

CAUTION

•DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Allow at least one hour for the lamp to cool before handling.

•DO NOT REMOVE ANY SCREWS except the lamp cover set screw and two lamp case screws. You could receive an electric shock.

•Do not touch the front surface portion of the replacement lamp body in which glass is used.

Touching the glass portion or bulb tip may result in a drop of the brightness or shortened bulb life.

•Turn off the main power to the projector and disconnect the power cord. Allow at least one hour for the lamp to cool.

•If you continue to use the lamp after 2000 hours 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:

1.Loosen the single captive screw that secures the lamp housing cover and remove the cover.

2.Loosen the two captive screws securing the lamp case.

3.Remove the lamp by pulling out the complete assembly.

4.Install a new lamp case assembly and secure it in place with the two captive screws.

CAUTION: Do not use a lamp other than the NEC replacement lamp. Order this from your NEC dealer using your projector's model number.

5.Reattach the lamp housing cover and tighten the single captive screw.

6.After you install a new lamp, select [Display] from the main menu, and press the ENTER button. Then press the remote ▲/▼ button to select [Lamp

Usage], then press the NORMAL button to display the Reset menu. Press the remote ▲/▼ button to select [Yes] and press the ENTER button.
