Cleaning
1. Unplug the projector before cleaning.
2. Clean the cabinet periodically with a damp cloth. If heavily soiled, use a mild
detergent. Never use strong detergents or solvents such as alcohol or thinner.
3. Use a blower or lens paper to clean the lens, and be careful not to scratch or
mar the lens.
Lamp Replacement
• Perform lamp replacement in accordance with the instructions on page 81.
• Be sure to replace the lamp when the Status light comes on. 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.
• 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 projector.
Fire and Shock Precautions
1. Ensure that there is sufficient ventilation and that vents are unobstructed to
prevent the build-up of heat inside your projector. Allow at least 3 inches
(10cm) of space between your projector and a wall.
2. Prevent foreign objects such as paper clips and bits of paper from falling into
your 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 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 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.

Important Safeguards
These safety instructions are to ensure the long life of your projector and to
prevent fire and shock. Please read them carefully and heed all warnings.
Installation
1. For best results, use your projector in a darkened room.
2. Place the projector on a flat, level surface in a dry area away from dust and
moisture.
3. Do not place your projector in direct sunlight, near heaters or heat radiating
appliances.
4. Exposure to direct sunlight, smoke or steam can harm internal components.
5. Handle your projector carefully. Dropping or jarring can damage internal
components.
6. Do not place heavy objects on top of the projector.
7. If installing the projector on the ceiling:
a. The ceiling must be strong enough to support the projector and the
installation must be in accordance with any local building codes.
b. The projector must be installed by qualified NEC service personnel.
Power Supply
1. The projector is designed to operate on a power supply of 100-120 or 220-240
V 50/60 Hz AC. Ensure that your power supply fits this requirement before
attempting to use your projector.
2. Handle the power cable carefully and avoid excessive bending. A damaged
cord can cause electric shock or fire.
3. If the projector is not to be used for an extended period of time, disconnect the
plug from the power outlet.
