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 screw-
driver to remove the lamp cover and lamp housing.
1. Loosen the lamp cover screw until the screwdriver goes into a free-
wheeling condition. Press firmly and slide the lamp cover off. The lamp
cover screw is not removable.
3. Insert a new lamp housing until the lamp housing is plugged into the
socket.
CAUTION
Do not use a lamp other than the NEC replacement lamp (LT70LP).
Order this from your NEC dealer.
Secure it in place with the screw.
Be sure to tighten the screw.
4. Reattach the lamp cover.
Slide the lamp cover back until it snaps into place.
Tighten the lamp cover screw.
Be sure to tighten the screw.
2. Loosen the screw securing the lamp housing until the screwdriver goes
into a freewheeling condition. The screw is 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 interlock.

NOTE: When the lamp exceeds 1600 hours (up to 2100 hours in Eco mode) of
service, the projector cannot turn on and the menu is not displayed. If this
happens, press the Help button on the remote control for a minimum of 10
seconds while in standby mode. When the lamp time clock is reset to zero, the
LAMP indicator goes out.
