MAINTENANCE
This section describes the simple maintenance procedures you should
follow to replace the lamp and clean the filter.
Replacing the LampAfter your lamp has been operating for 2000 hours (up to 3000 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 work-
ing, replace it at 2000 (up to 3000 hours in Eco mode) hours to mainta\
in
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 2100
(up to 3100 hours in Eco mode) hours of service. If this hap-
pens, be sure to replace the lamp. If you continue to use the
lamp after 2000 hours (up to 3000 hours in Eco mode) of use,
the lamp bulb may shatter, and pieces of glass may be scat-
tered 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 lamp cover screw until the screwdriver goes into a free-
wheeling condition and remove the lamp cover. The lamp cover screwis 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 notremovable.
Remove the lamp housing by holding it.
NOTE:  There is an interlock on this case to prevent the risk of electrical sho\
ck.Do not attempt to circumvent this interlock.

→ 
[Default] → [Clear
Lamp Hour Meter] to reset the lamp usage hours.
NOTE:  When the lamp exceeds 2100 hours (up to 3100 hours in Eco mode)
of service, the projector cannot turn on and the menu is not displayed. If thi\
s happens, press the Help button on the remote control for a minimum of 10\

Cleaning the Cabinet and the Lens
Cleaning
Cleaning or Replacing the Filter
The air-filter sponge keeps the inside of the projector from dust or dir\
t
and should be cleaned after every 100 hours of operation (more often in\
dusty conditions). If the filter is dirty or clogged, your projector ma\
y over-
heat.
CAUTION
•Turn off the projector, turn off the main power switch and un-
plug the projector before replacing the filter.
• Only clean the outside of the filter cover with a vacuum cleaner.
• Do not attempt to operate the projector without the filter cover.
To  clean the air-filter:
V acuum the filter-through the filter cover.
Catch
To  reset the filter usage time, from the menu, select [Default]  → [Clear
Filter Usage].
See also page E-29 for resetting the filter usage time.
To  replace the filter (sponge):
1. Remove the filter cover by pushing up on the catch of the cover until
you feel it detach.
2. Gently peel off the filter (sponge) and replace it with the new one. 3. Reinstall the new filter cover.
NOTE: 
Do not wash the filter with soap and water. Soap and water will damage
the filter membrane. Before replacing the filter, remove dust and dirt from the
projector cabinet. Keep out dust and during filter replacement.
NOTE:  When you replace the lamp, it is also wise to replace the filter. The filtercomes in the same package with your replacement lamp.
1. Turn off the projector before cleaning.
2. Clean the cabinet periodically with a damp cloth. If heavily soiled, use a mild detergent. Never use strong detergents or solvents suchas alcohol or thinner.
3. Use a blower or lens paper to clean the lens, and be careful not to scratch or mar the lens.
