MAINTENANCE
This section describes the simple maintenance procedures you should
follow to replace the lamp and the filter, and to clean the filter, the cabi-
net and the lens.
Replacing the Lamp
After your lamp has been operating for 2000 hours (Normal mode on
the standard life lamp) 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 as soon as possible 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 two lamp case
screws. You could receive an electric shock.
• The projector will turn off and go into stand by mode after 2100
hours (Normal mode on the standard life lamp) of service. If this
happens, be sure to replace the lamp. If you continue to use the
lamp after 2000 hours (Normal mode on the standard life lamp)
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:
NOTE: The optional lamp comes with a flat-head screwdriver.
1. Remove the lamp cover by pushing two grooves lightly with the flat-
head screwdriver.
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
(Standard life lamp: MT70LP (MT1075), MT60LP (MT1065) or Ex-
tended life lamp: MT60LPS).
5. Secure it in place with the two screws.
Be sure to tighten the screws.
6. Reattach the lamp cover.
7. Snap the lamp cover into place.
NOTE: Replacing a new lamp automatically clears the lamp usage hours.
NOTE: The lamp housing has an EEPROM chip memorizing its amount of usage
hours. You can check the amount usage hours in Information of the menu. (The
standard lamp and the optional lamp have an EEPROM chip in it so that when
you remove it, your lamp usage hours are saved in its own memory. The projec-
tor reads the lamp usage hours from the EEPROM chip to display them in Infor-
mation of the menu.)
