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 3000 hours 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 3000 hours to main-
tain 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,
turn off the main power switch and then disconnect the power
cable. Allow at least one hour for the lamp to cool before han-
dling.
• DO NOT REMOVE ANY SCREWS except the lamp cover screw
and two lamp case screws. You could receive an electric shock.
• The projector will turn off and go into stand by mode after 3100
hours of service. If this happens, be sure to replace the lamp. If
you continue to use the lamp after 3000 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 replace-
ment.
To replace the lamp:
1. Loosen the lamp cover screw until the screwdriver goes into a free-
wheeling condition and remove the lamp cover. 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 (VT60LP).
Order this from your NEC dealer.
Secure it in place with the two screws.
Be sure to tighten the screws.
4. Reattach the lamp cover.
Tighten the lamp cover screw.
Be sure to tighten the screw.
2. Loosen the two screws securing the lamp housing until the screw-
driver goes into a freewheeling condition. The two screws are not
removable.
Remove the lamp housing by holding it.
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 3100 hours of service, the projector cannot
turn on and the menu is not displayed. If this happens, press and hold the
ON/STAND BY and CANCEL buttons on the remote control simultaneously
for a minimum of 10 seconds while in standby mode. When the lamp time
clock is reset to zero, the LAMP indicator goes out.
