MAINTENANCE
This section describes the simple maintenance procedures you should follow to replace the lamp and the filter, and to clean the filter, the cabinet and the lens.
4.Insert a new lamp housing until the lamp housing is plugged into the socket.
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.
CAUTION: Do not use a lamp other than the NEC replacement lamp
(Standard life lamp: MT70LP (MT1075), MT60LP (MT1065) or Ex-

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 projector reads the lamp usage hours from the EEPROM chip to display them in Information of the menu.)
