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 w\
all.
• 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 falli\
ng 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 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 el\
ectrical 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 y\
our eyes could result.
• Keep any items such as magnifying glass out of the light path of the pro\
jector. The light being projected from the
lens is extensive, therefore any kind of abnormal objects that can redir\
ect 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 pr\
ojector 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 ve\
nt.
Doing so could lead to the object melting or getting your hands burned f\
rom 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 instructi\
ons described in this users 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 proj\
ector.
• Turn off the projector and unplug the power cable before cleaning the cabinet o\
r replacing the lamp.
Place the projector in a horizontal position
The tilt angle of the projector should not exceed 10 degrees, nor should\
 the projector be installed in any way other
than the desktop and ceiling mount, otherwise lamp life could decrease d\
ramatically.

CAUTION
•Do not use the tilt-foot for purposes other than originally intended. Mi\
suses 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 sc\
rews that attach the carrying handle
to the projector cabinet are tight.
Insufficient tightening of the two screws could result in the projector falli\
ng and causing injury.
• Select [High] in Fan mode if you continue to use the projector for conse\
cutive 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 ca\
ble 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  52.
• 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 th\
em 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.
