6. MAINTENANCE

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” light 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 a full minute, 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.

It features an intuitive on-screen menu, providing easy access to a range of functions including picture adjustments, source selection, and setup options. This user-friendly interface contributes to a smoother operation, allowing presenters to focus on their content rather than technical difficulties.

Moreover, the NEC GT1150 is built to last, with an expected lamp life of up to 4,000 hours in normal mode, which can stretch to 5,000 hours in eco mode. This longevity reduces maintenance costs and minimizes downtime due to lamp replacements.
