MAINTENANCE
This section describes the simple maintenance procedures you should
follow to replace the lamp, and to clean the cabinet and the lens.
Replacing the LampAfter your lamp has been operating for 2000 hours (up to 3000 hours :
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 hours (up to 3000 hours : Eco mode) 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 90 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
hours (up to 3100 hours : Eco mode) of service. If this happens,
be sure to replace the lamp. If you continue to use the lamp after
2000 hours (up to 3000 hours : Eco mode) of use, the lamp bulb
may shatter, and pieces of glass may be scattered in the lamp
housing. 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 screw
is not removable.
Interlock 2. Loosen the two screws securing the lamp housing until the screw-
driver goes into a freewheeling condition. The two screws are not
removable.
3. 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.
4. 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
(LT60LPK).
5. Secure it in place with the two screws.Be sure to tighten the screws.
6. Reattach the lamp cover.
7. Tighten the lamp cover screw.
Be sure to tighten the screw.
8. After you install a new lamp, from the menu select [Setup] 
→ [Page
2] → [Lamp Hour] to reset the lamp usage hours.
If the projector will not be turned on after using 2100 hours (up to
3100 hours : Eco mode) of service, press and hold the [Help] button
on the remote control for ten seconds or longer to reset the lamp time
clock to zero.

CleaningCleaning the Cabinet and the Lens
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 such
as alcohol or thinner.
3. Use a blower or lens paper to clean the lens, and be careful not to
scratch or mar the lens.
Lens ProtectorThe lens barrel has threads on the outside for mounting a commercially
available lens protector (φ 82mm) to protect the lens from dirt, dust,
scratches and damage. Note that both a lens protector and the supplied
lens cap cannot be used at the same time.
CAUTION: Use only transparent lens protectors designed for lens
protection. Use of filters for light reduction and special effects, such
as ND (Neutral Density) filters and color filters, can absorb heat,
resulting in damage to the filter and the projector.

mode•Check that the power cable is plugged in and that the power button on the projector cabinet or the remote
control is on. See pages E-17 and 18.
•Ensure that the lamp cover is installed correctly. See page E-43.
•Check to see if the projector has overheated or the lamp usage exceeds 2100 hours (up to 3100 hours : Eco
mode). If there is insufficient ventilation around the projector or if the room where you’re presenting is par-
ticularly warm, move the projector to a cooler location.
•The lamp may fail to light. Wait a full minute and then turn on the power again.
•The lamp has reached the end of its usable life. Replace the lamp.
•Use the SOURCE button on the projector cabinet or the VIDEO, the S-VIDEO, the COMP.V (COMPONENT), the
COMP. (COMPUTER), the DVI or the VIEWER button on the remote control to select your source (Video, S-
Video, Component, Computer, DVI (DIGITAL) or Viewer). See page E-19.
•Ensure your cables are connected properly.
•Use menus to adjust the brightness and contrast. See page E-29.
•Remove the lens cap.
•Reset the settings or adjustments to factory preset levels using the Reset in the Menu. See page E-37.
When using with a notebook PC, be sure to connect between the projector and the notebook PC before turning
on the power to the notebook PC. In most cases signal cannot be output from RGB output unless the notebook
PC is turned on after connecting with the projector.
*If the screen goes blank while using your remote control, it may be the result of the computers screen-
saver or power management software.
*If you accidentally hit the POWER button on the remote control, wait 90 seconds and then press the POWER
button again to resume.
•Reposition the projector to improve its angle to the screen. See page E-19.
•Use the 3DReform function to correct the trapezoid distortion. See page E-20.
•Adjust the focus. See page E-20.
•Reposition the projector to improve its angle to the screen. See page E-19.
•Ensure that the distance between the projector and screen is within the adjustment range of the lens. See page
E-12.
•Condensation may form on the lens if the projector is cold, brought into a warm place and is then turned on.
Should this happen, let the projector stand until there is no condensation on the lens.
•Use the SOURCE button on the projector cabinet or the VIDEO, the S-VIDEO, the COMP.V (COMPONENT), the
COMP. (COMPUTER), the DVI or the VIEWER button on the remote control to select your source (Video, S-
Video, Component, Computer, DVI (DIGITAL) or Viewer). See page E-19.
•Adjust the computer image manually with the Position/Clock in the Image. See page E-32.
•Install new batteries. See page E-10.
•Make sure there are no obstacles between you and the projector.
•Stand within 22 feet (7 m) of the projector. See page E-10.
•See the Status Indicator on page E-45.
•Press the AUTO ADJUST button on the projector cabinet or the AUTO ADJ. button on the remote control.
•Adjust the computer image manually with the Position/Clock in the Image. See page E-32.

What is HDCP/HDCP technology?
HDCP is an acronym for High-bandwidth Digital Content Protection. High bandwidth Digital Content Protection (HDCP) is a system for preventing
illegal copying of video data sent over a Digital Visual Interface (DVI).
If you are unable to view material via the DVI input, this does not necessarily mean the projector is not functioning properly.  With the implementation
of HDCP, there may be cases in which certain content is protected with HDCP and might not be displayed due to the decision/intention of the HDCP
community (Digital Content Protection, LLC).For more information contact your dealer.
