Lamp Replacement

Perform lamp replacement in accordance with the instructions on page E-37.

Be sure to replace the lamp when the Status light comes on. 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.

Allow a minimum of ONE minute to elapse between turning the lamp off and on. High voltage is applied to the lamp immediately when the power is turned on. Therefore turning the power off and quickly back on may shorten the life of your lamp and result in damage to your LCD projector.

Fire and Shock Precautions

1.Ensure that there is sufficient ventilation and that vents are unob- structed to prevent the build-up of heat inside your LCD projector. Allow at least 3 inches (10cm) of space between your LCD projector and a wall.

2.Prevent foreign objects such as paper clips and bits of paper from falling into your LCD projector. Do not attempt to retrieve any objects that might fall into your projector. Do not insert any metal objects such as a wire or screwdriver into your LCD project. If something should fall into your projector, disconnect it immediately and have the object removed by a qualified NEC service person.

3.Do not place any liquids on top of your LCD projector.

Do not look into the lens while the projector is on. Serious damage to your eyes could result.

Do not look into the laser pointer while it is on and do not point the laser beam at another person. Serious injury could result.
