
Important Informaton
Fre and Shock Precautons
• Ensure that there is sufcient 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 right 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 screw-
driver into your projector. If something should fall into your projector, disconnect it immediately and have the
object removed by a qualied 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 re.
• The projector is designed to operate on a power supply of 100-240V AC 50/60 Hz (NP61/NP41) or 200-240V
AC 50/60 Hz (NP61G/NP41G). Ensure that your power supply ts 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 re 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 melt-
ing 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 re.
- 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 projector serviced by a qualied 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.
• 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.
• Turn off the projector and unplug the power cable if the projector is not to be used for an extended period of
time.

v
Important Informaton
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.
• 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.
• Select [HIGH] in Fan mode if you continue to use the projector for consecutive days. (From the menu, select
[SETUP] → [OPTIONS(1)] → [FAN MODE] → [HIGH].)
• Do not unplug the power cable from the wall outlet or projector when the projector is powered on. Doing so
can cause damage to the AC IN connector of the projector and (or) the prong plug of the power cable.
To turn off the AC power supply when the projector is powered on, use a power strip equipped with a switch
and a breaker.
• 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.
• 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 Precautons
• 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 re.
• 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 59.
• 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 Characterstc
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:
• DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector
off and then disconnect the power cable. Allow at least one hour for the lamp to cool before handling.
• 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.

Federal Laws.
About Hgh Alttude mode
• Set [FAN MODE] to [HIGH ALTITUDE] when using the projector at altitudes approximately 5000 feet/1500 me-
ters or higher.
• Using the projector at altitudes approximately 5000 feet/1500 meters or higher without setting to [HIGH ALTI-
TUDE] can cause the projector to overheat and the protector could shut down. If this happens, wait a couple
minutes and turn on the projector.
• Using the projector at altitudes less than approximately 5000 feet/1500 meters and setting to [HIGH ALTI-
TUDE] can cause the lamp to overcool, causing the image to icker. Switch [FAN MODE] to [AUTO].
• Using the projector at altitudes approximately 5000 feet/1500 meters or higher can shorten the life of optical
components such as the lamp.

WARNING
* Installing your projector on the ceiling must be done
by a qualied 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°F/35°C to 40°C.
Note that [ECO] mode will be selected automatically
at 86°F to 104°F/30°C to 40°C when used in [HIGH
ALTITUDE].)
• 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.
Reectng the Image
Using a mirror to reflect your projector's image en-
ables 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 sys-
tem and your image is inverted, use the MENU and
SELECT buttons on your projector cabinet or your
remote control to correct the orientation. (→ page 49)
