NEC GT2150 - Manual (Page 62)

E – 52
This section describes the simple maintenance procedures you should
follow to replace the lamp and clean the filter.
Replacing the Lamp
After your lamp has been operating for 1500 hours (2000 hours : Eco
mode) or longer, the “Status” indicator in the cabinet will go on and the
message will appear. Even though the lamp may still be working, re-
place it at 1500 (up to 2000 hours : Eco mode) hours to maintain opti-
mal projector performance.
CAUTION
• DO NOT TOUCH THE LAMP immediately after it has been used. It will
be extremely hot. Turn the projector off, wait three minutes, and then
disconnect the power cable. Allow at least one hour for the lamp to
cool before handling.
• DO NOT REMOVE ANY SCREWS except the lamp cover screw and two
lamp housing screws. You could receive an electric shock.
• The projector will turn off and go into stand by mode after 1600 (2100
hours : Eco mode) hours of service. If this happens, be sure to replace
the lamp. If you continue to use the lamp after 1500 hours (2000 hours
: Eco mode) 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:
1. Loosen the lamp cover screw until the screwdriver goes into a
freewheeling condition and remove the lamp cover. The lamp cover
screw is not removable.
