							7-1
This section describes the simple maintenance procedures you
should follow to replace the lamp, and to clean the cabinet and
the mirror.
7-1. Replacing the Lamp
After 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 working, 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 dis-
connect 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 two lamp case screws. You could receive an
electric shock.
•The projector will turn off and go into stand by mode af-
ter 2100 hours (up to 3100 hours : Eco mode) of service.
If this happens, be sure to replace the lamp. If you con-
tinue 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 replace-
ment.
To replace the lamp:
1. Loosen the lamp cover screw until the screwdriver goes into a
freewheeling condition and remove the lamp cover. The lamp
cover screw is not removable.
2. Loosen the two screws securing the lamp housing until the
screwdriver goes into a freewheeling condition. The two screws
are not removable.3. Remove the lamp housing by pulling out the handle.
Interlock
7. Maintenance
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 [Projector
Options] 
→ [Setup] → [Page 4] → [Clear Lamp Hour Meter] 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.
NOTE: There is an interlock on this case to prevent the risk of electri-cal 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 replace-ment lamp (LT60LPK).

7-2. Cleaning
Cleaning the Cabinet
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.
*The projector has a sensor which detects an object in front of
the largest mirror or in the light path. If the sensor detects any
object, the projector will not turn on. If this happens while the
projector is turned on, the image is muted. In either case the
STATUS indicator flashes in red.
*The projector has a temperature sensor which detects exces-
sive heat. If the sensor detects heat in the bottom of the mir-
ror or in the light path, the projector will not turn on. If this
happens while the projector is turned on, the projector will
turn off (the idle mode). In either case the STATUS indicator
flashes in red.
Handling and Care of Mirror surface
If the projector is not to be used for an extended period of time,
close the mirror cover.
This will protect the projector against dropping an object or gath-
ering dust.
Consult with your dealer when using the projector exposed to
smoke or dust.
Long-term exposure to sulfide can corrode the mirror surface.
Cleaning the mirror face
Keep finger prints off the mirror surface. Do not scratch the mir-
ror surface with a hard or pointed object.
Leaving a defect in the mirror surface might cause an unwanted
shadow and poor picture quality.
If the mirror surface is soiled with fingers prints or dust, wipe
them off with the supplied cleaning cloth.
When removing sandy dust, use a blower to blow off dust or
brush it off softly and wipe the mirror surface with the supplied
cleaning cloth.
Do not blow your breath against the mirror surface, which can
accidentally put your saliva on the mirror surface.
Leaving foreign grease stains, oil-smudged finger prints or salt
on the mirror surface can cause damage to the reflective coat-
ing on the mirror surface.
Use only the supplied cleaning cloth to clean the mirror surface.
Failure to do so can mar the mirror surface.
Do not force the cleaning cloth against the mirror surface or ap-
ply excessively strong pressure against it. Do not scratch it with
your nails while wiping off.
Never use strong detergents or solvents such as thinner or ben-
zene. Doing so can corrode the reflective coating on the mirror
surface.
If heavily soiled and wiping with the cleaning cloth will not work,
use absolute alcohol. After the mirror surface is dried, wipe it
with the cleaning cloth again.
If the supplied cleaning cloth is soiled, wash it. It is recommended
you wash it every after two to three uses.
Do not allow long-term close contact with rubber or vinyl prod-
ucts because this could cause the reflective coating of the mir-
ror surface to deteriorate.
Do not spray volatile substances such as insect repellent on the
mirror surface.

•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 2-7 and 3-1.
•Ensure that the lamp cover is installed correctly. See page 7-1.
•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 particularly warm, move the projector to a cooler location.
•Check to see if the Control Panel Key Lock function is enabled. If this function is enabled, cancel
it by pressing and holding the CANCEL button on the cabinet for a minimum of 10 seconds or
using the menu. See page 6-17.
