5MAINTENANCE

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

Replacing The Lamp

After your lamp has been operating for 2000 hours or longer, the red “status” light in the cabinet will go on and the lamp icon will appear on the above right of the screen whenever the projector is turned on. The lamp icon remains on after 2100 hours of service. Even though the lamp may still be working, replace it at 2000 hours to maintain optimal projec- tor performance.

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.

•Do not touch the front surface portion of the replacement lamp body in which glass is used.

Touching the glass portion or bulb tip may result in a drop of the brightness or shortened bulb life.

•Turn off the main power to the projector and disconnect the power cord. Allow at least one hour for the lamp to cool.

•If you continue to use the lamp after 2000 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.

To replace the lamp:

1.Loosen the single captive screw that secures the lamp housing cover and remove the cover.

2.Loosen the two captive screws securing the lamp case.

3.Remove the lamp by pulling out the complete assembly.

4.Install a new lamp case assembly and secure it in place with the two captive screws.

CAUTION: Do not use a lamp other than the NEC replacement lamp. Order this from your NEC dealer using your projector's model number.

5.Reattach the lamp housing cover and tighten the single captive screw.

6.After you install a new lamp, select [Display] from the main menu, and press the ENTER button. Then press the remote ▲/▼ button to select [Lamp

Usage], then press the NORMAL button to display the Reset menu. Press the remote ▲/▼ button to select [Yes] and press the ENTER button.

This resets the lamp clock back to zero.

Note: When you replace the lamp, it is also wise to replace the filter. The filter comes in the same package with your replacement lamp.

GT2000, GT2000R specifications

The NEC GT2000 and GT2000R are renowned projectors that have established themselves in the realm of high-performance visual equipment, catering primarily to the needs of businesses and educational institutions. These projectors are celebrated for their exceptional image quality, versatility, and advanced features, making them a popular choice among users seeking reliability and performance.

One of the primary features of the GT2000 series is its high brightness capability. With a brightness of up to 2,500 ANSI lumens, these projectors can deliver clear and vibrant images even in well-lit environments, ensuring that presentations and lectures maintain their visual integrity regardless of ambient light conditions. This makes them ideal for large conference rooms and classrooms where visibility is crucial.

The GT2000 series also boasts impressive resolution specifications. The GT2000 offers a native resolution of XGA (1024x768 pixels), while the GT2000R enhances this to a WXGA (1280x800 pixels), providing a wider aspect ratio and higher detail for images. This improved resolution is particularly beneficial for displaying detailed graphics, charts, and videos, making them suitable for a variety of presentation types.
