RF Interference (for USA only)
WARNING
The Federal Communications Commission does not allow any modications or changes to the unit
EXCEPT those specied by NEC Display Solutions of America, Inc. in this manual. Failure to comply with
this government regulation could void your right to operate this equipment. This equipment has been test-
ed and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be deter-
mined by turning the equipment off and on, the user is encouraged to try to correct the interference by one
or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio / TV technician for help.
For UK only: In UK, a BS approved power cord with moulded plug has a Black (ve Amps) fuse installed for
use with this equipment. If a power cord is not supplied with this equipment please contact your supplier.
Important Safeguards
These safety instructions are to ensure the long life of your projector and to prevent re and shock. Please
read them carefully and heed all warnings.
Installation
• Do not place the projector in the following conditions:
- on an unstable cart, stand, or table.
- near water, baths, or damp rooms.
- in direct sunlight, near heaters, or heat radiating appliances.
- in a dusty, smoky or steamy environment.
- on a sheet of paper or cloth, rugs or carpets.
• If you wish to have the projector installed on the ceiling:
- Do not attempt to install the projector yourself.
- The projector must be installed by qualied technicians in order to ensure proper operation and reduce
the risk of bodily injury.

Important Information
Fire and Shock Precautions
• Ensure that there is sufcient 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 as it can become heated while the projector is turned on and im-
mediately after the projector is turned off.
• Prevent foreign objects such as paper clips and bits of paper from falling into your projector. Do not at-
tempt 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 immedi-
ately and have the object removed by a qualied 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. Ensure that your power
supply ts this requirement before attempting to use your projector.
• Do not look into the mirror while the projector is on. Serious damage to your eyes could result.
• Keep any items (magnifying glass etc.) out of the light path of the projector. The light path being projected
from the mirror is extensive, therefore any kind of abnormal objects that can redirect light coming out of
the mirror, can cause unpredictable outcome such as a re or injury to the eyes.
• Do not block the light path between the light source and the mirror with any objects. Doing so could cause
the object to catch on re.
• Do not place any objects, which are easily affected by heat, in front of the projector mirror 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 cord carefully. A damaged or frayed power cord can cause electric shock or re.
- Do not use any power cord other than the one supplied.
- Do not bend or tug the power cord excessively.
- Do not place the power cord under the projector, or any heavy object.
- Do not cover the power cord with other soft materials such as rugs.
- Do not heat the power cord.
- Do not handle the power plug with wet hands.
• Turn off the projector, unplug the power cord and have the projector serviced by a qualied service per-
sonnel under the following conditions:
- When the power cord 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 cord and any other cables before carrying the projector.
• Turn off the projector and unplug the power cord before cleaning the cabinet or replacing the lamp.
• Turn off the projector and unplug the power cord if the projector is not to be used for an extended period
of time.
• When using a LAN cable:
For safety, do not connect to the connector for peripheral device wiring that might have excessive voltage.

Important Information
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 short, heat, or take apart batteries.
• Do not 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 pages 61-62.
• 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:
• 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 cord. 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 projec-
tor. Glass fragments could fall if the lamp has been burned out.
Note for US Residents
The lamp in this product contains mercury. Please dispose according to Local, State or Federal Laws.
Health precautions to users viewing 3D images
• Before viewing, be sure to read health care precautions that may be found in the user’s manual included
with your LCD shutter eyeglasses or your 3D compatible content such as DVDs, video games, com-
puter’s video les and the like.
To avoid any adverse symptoms, heed the following:
- Do not use LCD shutter eyeglasses for viewing any material other than 3D images.
- Allow a distance of 2 m/7 feet or greater between the screen and a user. Viewing 3D images from too
close a distance can strain your eyes.
- Avoid viewing 3D images for a prolonged period of time. Take a break of 15 minutes or longer after
every hour of viewing.
- If you or any member of your family has a history of light-sensitive seizures, consult a doctor before
viewing 3D images.
- While viewing 3D images, if you get sick such as nausea, dizziness, queasiness, headache, eyestrain,
blurry vision, convulsions, and numbness, stop viewing them. If symptoms still persist, consult a doc-
tor.
