❹ Replacing the Lamp
When the lamp reaches the end of its life, the LAMP indicator on the cabinet will blink in orange and the message "THE
LAMP HAS REACHED THE END OF ITS USABLE LIFE. PLEASE REPLACE THE LAMP. USE THE SPECIFIED
LAMP FOR SAFETY AND PERFORMANCE." will appear (*). Even though the lamp may still be working, replace the
lamp to maintain the optimal projector performance as soon as possible. After replacing the lamp, be sure to clear
the lamp hour meter. (→ page 134)
CAUTION
• 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 cord. Allow at least one hour for the lamp to cool before handling.
• Use the specified lamp for safety and performance.
• DO NOT REMOVE ANY SCREWS except one lamp cover screw and two lamp housing screws. You could receive
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 on the glass surface might cause
an unwanted shadow and poor picture quality.
• The bar indicator as the LAMP LIFE REMAINING shows the percentage of remaining bulb life.
When the remaining lamp time reaches 0%, the LAMP LIFE REMAINING bar indicator changes from 0% to 100
Hours as the grace period for replacing lamp and starts counting down. In the grace period, the LAMP indicator
will blink in orange.
When it reaches 0 hours, the LAMP indicator will start blinking in red.
If you continue to use the lamp after the lamp reaches the end of its life, 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 hap-
pens, contact your NEC dealer for lamp replacement.
