E-3
Important Safeguards
These safety instructions are to ensure the long life of your
projector and to prevent fire and shock. Please read them care-
fully 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 inter-
nal components.
5. Handle your projector carefully. Dropping or jarring can dam-
age internal components.
6. Do not place heavy objects on top of the projector.
7. If you wish to have the projector installed on the ceiling:
a. Do not attempt to install the projector yourself.
b. The projector must be installed by qualified technicians in order
to ensure proper operation and reduce the risk of bodily injury.
c. In addition, the ceiling must be strong enough to support the
projector and the installation must be in accordance with any
local building codes.
d. Please consult your dealer for more information.
Power Supply
1. 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.
2. Handle the power cable carefully and avoid excessive bend-
ing. 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 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.
CAUTION
Do not turn off the main power or unplug the power
cable from the wall outlet under any one of the follow-
ing circumstances. Doing so can cause damage to the
projector:
•Immediately after the power cable is plugged into the
wall outlet (when the POWER indicator has not
changed to a steady orange glow).
•Immediately after the cooling fan stops working (The
cooling fan continues to work for 90 seconds after
the projector is turned off with the POWER button).

E-4
Lamp Replacement
•To replace the lamp, follow all instructions provided on page
E-36.
•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 90 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.
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 pro-
jector. 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 pa-
per 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, dis-
connect it immediately and have the object removed by a
qualified NEC service personnel.
3. Do not place any liquids on top of your projector.
• Do not look into the lens while the projector is on. Serious dam-
age to your eyes could result.
• Keep any items such as magnifying glass out of the light path of
the projector. The light being projected from the lens is exten-
sive, 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.
• Do not cover the lens with the supplied lens cap or equivalent
while the projector is on. Doing so can lead to melting of the cap
and possibly burning your hands due to the heat emitted from
the light output.

Introduction to the LT75Z Projector
This section introduces you to your new LT75Z Projector and
describes the features and controls.
Congratulations on Your Purchase of The LT75Z
Projector
The LT75Z is one of the very best projectors available today.
The LT75Z enables you to project precise images up to 200
inches across (measured diagonally) from your PC or
Macintosh computer (desktop or notebook), VCR, DVD player,
document camera or a laser disc player.
You can use the projector on a tabletop or cart, you can use
the projector to project images from behind the screen, and
the projector can be permanently mounted on a ceiling*1. The
remote control can be used wirelessly.
Features you’ll enjoy:
•Simple set up and operation.
•A high-performance 135 watt NSH lamp.
•The supplied wireless remote control that operates the pro-
jector from the front or rear.
•The image can be projected between 30 and 200 inches
(measured diagonally).
•Keystone correction allows you to correct trapezoidal distor-
tion so that the image is square.
•You can choose between video modes depending on your
source:
"normal" for a typical picture, "natural" for true color repro-
duction.
•An image can be projected from in front or behind a screen,
and the projector can even be installed on the ceiling.
•NEC Technologies’exclusive Advanced AccuBlend intelli-
gent pixel blending technology - an extremely accurate im-
age compression technology - offers a crisp image with
