➌ Replacing The Lamp And The Cooling Pump - NEC NP41G User Manual

➌ Replacing the Lamp and the Cooling Pump
After your lamp has been operating for 2500 hours (up to 3500 hours in ECO mode) or longer, the LAMP indica-
tor in the cabinet will blink red and the message [THE LAMP HAS REACHED THE END OF ITS USABLE LIFE.
PLEASE REPLACE THE LAMP.] will appear. Even though the lamp may still be working, replace it at 2500 (up to
3500 hours in ECO mode) hours to maintain optimal projector performance. After replacing the lamp, be sure to
clear the lamp hour meter. (→ page 70)
CAUTION
• The optional lamp comes with the cooling pump.
After replacing the lamp, be sure to replace the cooling pump, too.
• DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off
and then disconnect the power cable. Allow at least one hour for the lamp to cool before handling.
• DO NOT REMOVE ANY SCREWS except one lamp cover screw and two lamp housing screws. You could re-
ceive an electric shock.
• Do not break the glass on the lamp housing.
Keep finger prints off the glass surface on the lamp housing. Leaving finger prints in the glass surface might
cause an unwanted shadow and poor picture quality.
• The projector will turn off and go into standby mode after 2600 (up to 3600 hours in ECO mode) hours of ser-
vice. If this happens, be sure to replace the lamp. If you continue to use the lamp after 2500 hours (up to 3500
hours in ECO mode) of use, the lamp bulb may shatter, and pieces of glass may be scattered 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.
