WARNING

The Federal Communications Commission does not allow any modifications or changes to the unit EXCEPT those specified by NEC Technologies in this manual. Failure to comply with this government regulation could void your right to operate this equipment.

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a commercial installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at their own expense.

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.

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 deter gents 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 quickl y 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 retrie ve any objects that might fall into your projector. Do not insert any metal objects such as a wire or scre wdr i ver 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.
