Important Information
Fire and Shock Precautions
•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 (10cm) of space between your projector and a wall.
•Do not try to touch the ventilation outlet on the left front (when seen from the front) as it can become heated while
the projector is turned on and immediately after the projector is turned off.
•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 service personnel.
•Do not place any objects on top of the projector.
•Do not touch the power plug during a thunderstorm. Doing so can cause electrical shock or fire.
•The projector is designed to operate on a power supply of 100-240V AC 50/60 Hz. Ensure that your power supply
fits this requirement before attempting to use your projector.
•Do not look into the lens while the projector is on. Serious damage 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 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.
•Do not cover the lens with the black 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.
•Do not place any objects, which are easily affected by heat, in front of the projector lens or a projector exhaust vent.
Doing so could lead to the object melting or getting your hands burned from the heat that is emitted from the light
output and exhaust.
•Handle the power cable carefully. A damaged or frayed power cable can cause electric shock or fire.
- Do not use any power cables than the supplied one.
- Do not bend or tug the power cable excessively.
- Do not place the power cable under the projector, or any heavy object.
- Do not cover the power cable with other soft materials such as rugs.
- Do not heat the power cable
- Do not handle the power plug with wet hands.
•Turn off the projector, unplug the power cable and have the object removed by a qualified NEC service personnel
under the following conditions:
- When the power cable or plug is damaged or frayed.
- If liquid has been spilled into the projector, or if it has been exposed to rain or water.
- If the projector does not operate normally when you follow the instructions described in this user's manual.
- If the projector has been dropped or the cabinet has been damaged.
- If the projector exhibits a distinct change in performance, indicating a need for service.
- If the projector is not to be used for an extended period of time.
•Disconnect the power cable and any other cables before carrying the projector
•Turn off the projector and unplug the power cable before cleaning the cabinet or replacing the lamp.

•Do no use the tilt-foot for purposes other than originally intended. Misuses such as gripping the tilt-foot or
hanging on the wall can cause damage to the projector.
•Do not send the projector in the soft case by parcel delivery service or cargo shipment. The projector inside
the soft case could be damaged.
•When carrying the projector by the carrying handle, make sure the two screws that attach the carrying handle
to the projector cabinet are tight.
Insufficient tightening of the two screws could result in the projector falling and causing injury.
•Select [High] in Fan mode if you continue to use the projector for consecutive days. (From the menu, select
[Setup] → [Options] → [Fan Mode] → [High].)
•Do not turn off the AC power by pressing the main power switch or by unplugging the power cable when the
projector is powered on.
•Do not turn off the AC power for 60 seconds after the lamp is turned on and while the POWER indicator is blinking
green.Doing so could cause premature lamp failure.
Remote Control Precautions
•Handle the remote control carefully.
•If the remote control gets wet, wipe it dry immediately.
•Avoid excessive heat and humidity.
•Do not heat, take apart, or throw batteries into fire.
•If you will not be using the remote control for a long time,remove the batteries.
• ’Ensure that you have the batteries polarity (+/-) aligned correctly.
•Do not use new and old batteries together, or use different types of batteries together.
•Dispose of used batteries according to your local regulations.
Lamp Replacement
•To replace the lamp, follow all instructions provided on page .51
•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 dealer for lamp replacement.
A Lamp Characteristic
The projector has a high-pressure mercury lamp as a light source.
A lamp has a characteristic that its brightness gradually decreases with age. Also repeatedly turning the lamp on
and off will increase the possibility of its lower brightness.
CAUTION:
When removing the lamp from a ceiling-mounted projector, make sure that no one is under the projector. Glass
fragments could fall if the lamp has been burned out.

2. Installation and Connections
WARNING
* Installing your projector on the ceiling must be done
by a qualified technician. Contact your NEC dealer
for more information.
* Do not attempt to install the projector yourself.
•Only use your projector on a solid, level surface. If the
projector falls to the ground, you can be injured and
the projector severely damaged.
•Do not use the projector where temperatures vary
greatly. The projector must be used at temperatures
between 41 F (5 C) and 104 F (40 C) (Eco mode˚ ˚ ˚ ˚
selected automatically at 95 F to 104 C to 40˚ ˚F/35˚ ˚C).
•Do not expose the projector to moisture, dust, or
smoke. This will harm the screen image.
•Ensure that you have adequate ventilation around your
projector so heat can dissipate. Do not cover the vents
on the side or the front of the projector.
Reflecting the Image
Using a mirror to reflect your projector s image enables’
you to enjoy a much larger image when a smaller space
is required. Contact your NEC dealer if you need a mirror
system. If you're using a mirror system and your image
is inverted, use the MENU and SELECT buttons on your
projector cabinet or your remote control to correct the
orientation. ( page →44)

This section describes how to turn on the projector and to project a picture onto the screen.
Turning on the Projector
NOTE:
•The projector has two power switches: a main power switch and a POWER (ON/STAND BY) button (POWER ON and OFF on the
remote control).
•When plugging in or unplugging the supplied power cable, make sure that the main power switch is pushed to the off (
䡬
)
position. Failure to do so may cause damage to the projector.
1. To turn on the main power to the projector, press the
Main Power switch to the on position ( I ).
The POWER indicator will light orange.
See the Power Indicator section.(→ page 54)
2. Remove the lens cap
3. Press the POWER (ON/STAND BY) button on the
projector cabinet or the POWER ON button on the
remote control for 1 second.
The POWER indicator will turn to green and the
projector will become ready to use.
After you turn on your projector, ensure that the
computer or video source is turned on and that your
lens cap is removed.
NOTE: When no signal is available, a blue screen is displayed at
the factory default.
When the projector displays a blue or black screen, the projector
will automatically switch to the Eco mode.
The projector will return to the Normal mode once a signal is
connected.
NOTE: If you turn on the projector immediately after the lamp is
turned off or when the temperature is high, the fans run without
displaying an image for some time and then the projector will
display the image.
CAUTION:
The projector cannot be turned off for 60 seconds after the
lamp is turned on and while the POWER indicator is blinking
green. Doing so could cause premature lamp failure.
20
3. Projecting an Image (Basic Operation)
Note on Startup screen (Menu Language Select screen)
When you first turn on the projector, you will get the Startup menu. This menu gives you the opportunity to select one
of the 8 menu languages.
To select a menu language, follow these steps:
1. Use the SELECT
or
button to select one of the 8
languages from the menu.
2. Press the ENTER button to execute the selection.
After this has been done, you can proceed to the menu op-
eration.
If you want, you can select the menu language later.
( and )→ [Language] on page 38 43
NOTE: Immediately after turning on the projector, screen flicker may occur. This is normal. Wait 3 to 5 minutes until the lamp
lighting is stabilized.
When the Lamp mode is set to Eco, the LAMP indicator will light green.
If one of the following things happens, the projector will not turn on.
•If the internal temperature of the projector is too high, the projector detects abnormal high temperature. In this
condition the projector will not turn on to protect the internal system. If this happens, wait for the projector's internal
components to cool down.
•When the lamp reaches its end of usable life, the projector will not turn on. If this happens, replace the lamp.
•If the lamp fails to light, and if the STATUS indicator flashes on and off in a cycle of six times, wait a full minute and
then turn on the power.

Adjustable Tilt
Foot Button
Place your projector on a flat level surface and ensure that the projector is
square to the screen.
Lift the front edge of the projector to center the image vertically.
* If the projected image does not appear square to the screen then use the
Keystone feature for proper adjustment. (→ page 24)
Move the projector left to center the image horizontally on the screen.
Adjust the Tilt Foot
1. Lift the front edge of the projector.
CAUTION:
Do not try to touch the ventilation outlet during Tilt Foot adjustment as it can
become heated while the projector is turned on and during its cool down
period after it is turned off.
2. Push and hold the Adjustable Tilt Foot Button on the front of the
projector to extend the adjustable tilt foot.
3. Lower the front of the projector to the desired height.
4. Release the Adjustable Tilt Foot Button to lock the Adjustable tilt
foot.
There is approximately 10 degrees (up) of adjustment for the front of the
projector.
Adjusting the height of a projected image or changing projection angle will
run the Auto Keystone correction function to quickly correct the vertical
distortion. The "Keystone" screen will be displayed.
For operating the "Keystone" screen, see " Correcting Keystone
Distortion" on page 24.
The rear foot height can be adjusted up to 0.4 inch/10 mm.
Rotate the rear foot to the desired height in order to square the image on
the projection surface, but the vertical distance from the bottom to the
desk or floor should be 0.4 inch /10mm to make the projector horizontal
on the flat surface.
NOTE: If you rotate the rear foot too much, it will come off from the bottom.
CAUTION:
•Do not use the tilt-foot for purposes other than originally intended.
Misuses such as using the tilt foot to carry or hang (from the wall or ceiling)
the projector can cause damage to the projector.
