RF Interference (for USA only)
WARNING
The Federal Communications Commission does not allow any modications or changes to the unit
EXCEPT those specied 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.
WARNING
• Do not use any other object than the projector’s sliding lens cover to cover the lens while the projector is
on. Doing so can cause the object to get extremely hot, and possibly resulting in a re or damage 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. Doing so could
lead to the object melting from the heat that is emitted from the light output.

Important Information
Fire and Shock Precautions
• 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 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 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. 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 (magnifying glass etc.) out of the light path of the projector. The light path 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 a re or injury to the eyes.
• Do not block the light path between the light source and the lens with any objects. Doing so could cause the
object to catch on re.
• 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 qualied 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 if the projector is not to be used for an extended period
of time.
• 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.
