This section describes the simple maintenance procedures you should follow
to replace the lamp and replace the batteries in the remote control.

Replacing The Lamp

After your lamp has been operating for 1000 hours or longer, the “sta-
tus” light in the cabinet will turn red. Even though the lamp may still be
working, replace it at 1000 hours to maintain optimal projector perform-
ance.
CAUTION
• DO NOT TOUCH THE LAMP immediately after it has been used. It will
be extremely hot. Allow at least one hour for the lamp to cool before
handling.
• DO NOT REMOVE ANY SCREWS except the lamp cover set screw
and two lamp case screws. You could receive an electric shock.
• Turn off the main power to the projector and disconnect the power cord.
Allow at least one hour for the lamp to cool.
• The projector will turn off and go into stand by mode after 1100 hours of
service. If this happens, be sure to replace the lamp. If you continue to
use the lamp after 1000 hours 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.
