IMPORTANT INFORMATION

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 4 inches (10 cm) 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 projector. If something should fall into your projector, disconnect
it immediately and have the object removed by a qualified NEC ser­vice personnel.

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

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

5. Keep any items such as magnifying glass out of the light path of the
projector. The light being projected from the lens is extensive, there­fore any kind of abnormal objects that can redirect light coming out of
the lens, can cause unpredictable outcome such as fire or injury to
the eyes.

6. Do not cover the lens with anything other than the built-in lens shutter
while the projector is on. Doing so can lead to melting of the cover
and possibly burning your hands due to the heat emitted from the
light output.

7. The projector is designed to operate on a power supply of 100-120 or
200-240 V 50/60 Hz AC. Ensure that your power supply fits this re­quirement before attempting to use your projector.

8. Handle the power cable carefully and avoid excessive bending.
A damaged cord can cause electric shock or fire.

9. If the projector is not to be used for an extended period of time, dis­connect the plug from the power outlet.

10. Do not touch the power plug during a thunderstorm. Doing so can
cause electrical shock or fire.

11. Do not handle the power plug with wet hands.

Lamp Replacement

•To replace the lamp, follow all instructions provided on page E-35.

• Be sure to replace the lamp when the message "The lamp has
reached the end of its usable life. Please replace the lamp." ap­pears. If you continue to use the lamp after the lamp has reached the
end of its usable life, 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 60 seconds to elapse after turning off the projec­tor. Then disconnect the power cable and allow 60 minutes to cool
the projector before replacing the lamp.

This section describes the simple maintenance procedures you should
follow to replace the lamp and clean the filter.

Replacing the Lamp

After your lamp has been operating for 1500 hours (up to 2000 hours in
Eco mode) or longer, the LAMP indicator in the cabinet will blink red and
the message will appear. Even though the lamp may still be working,
replace it at 1500 (up to 2000 hours in Eco mode) hours to maintain
optimal projector performance.

CAUTION

• DO NOT TOUCH THE LAMP immediately after it has been used. It
will be extremely hot. Turn the projector off, wait 60 seconds, and
then unplug the power cable. Allow at least one hour for the lamp
to cool before handling.

• DO NOT REMOVE ANY SCREWS except the lamp cover screw
and the lamp case screw. You could receive an electric shock.

• The projector will turn off and go into stand by mode after 1600
(up to 2100 hours in Eco mode) hours of service. If this happens,
be sure to replace the lamp. If you continue to use the lamp after
1500 hours (up to 2000 hours in Eco mode) 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:

NOTE: The replacement lamp comes with a flat-blade screwdriver. Use the screw­driver to remove the lamp cover and lamp housing.

1. Loosen the lamp cover screw until the screwdriver goes into a free­wheeling condition. Press firmly and slide the lamp cover off. The lamp
cover screw is not removable.

Catch

3. Inser t a new lamp housing until the lamp housing is plugged into the
socket.

CAUTION
Do not use a lamp other than the NEC replacement lamp (LT70LP).
Order this from your NEC dealer.

Secure it in place with the screw.
Be sure to tighten the screw.
