Power Supply
1. The LCD projector is designed to operate on a power supply of 110-120/
220-240 V 50/60 Hz AC. Ensure that your power supply fits this
requirement before attempting to use your LCD projector.
2. Handle the power cable carefully and avoid excessive bending. A dam-
aged cord can cause electric shock or fire.
3. If the LCD projector is not to be used for an extended period of time,
disconnect the plug from the power outlet.
Cleaning
1. Unplug the LCD 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.
4. Clean the air filter with a vacuum cleaner after every 100 hours of
operation.
a. Do not use water or any other liquid to clean the air filter.
b. Do not operate your LCD projector without the air filter.
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 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.

c. Ne pas utiliser le projecteur ˆ Žcran ˆ cristaux liquides (LCD) sans le
filtre ˆ air.
PrŽcautions pour Žviter un incendie ou une
Žlectrocution
1. 
tion de chaleur ˆ lÕintŽrieur du projecteur ˆ Žcran ˆ cristaux liquides
(LCD). SÕassurer que les trous de ventilation ne sont pas obstruŽs. Laisser
un espace dÕau moins 10 cm (quatre pouces) entre le projecteur ˆ Žcran ˆ
cristaux liquides (LCD) et les murs.
