DOC Compliance Notice
This Class B digital apparatus meets all requirements of the Canadian
Interference-Causing Equipment Regulations.
Acoustic Noise Information Ordinance-3. GSGV:
The sound pressure level is less than 70 dB (A) according
to ISO 3744 or ISO 7779.
CAUTION
•Avoid displaying stationary images for a prolonged period of time.
Doing so can result in these images being temporarily
sustained on the surface of the LCD panel.
If this should happen, continue to use your projector. The
static background from previous images will disappear.
• Do not put the projector on its side when the lamp is
turned on.
Doing so may cause damage to the projector.
RF Interference
WARNING
The Federal Communications Commission does not allow any
modifications or changes to the unit EXCEPT those specified
by NEC Soluctions (America), Inc. in this manual. Failure to comply with this government regulation could void your right to
operate this equipment. This equipment has been tested 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 determined 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.
In UK, a BS approved power cable with moulded plug has a Black (five
Amps) fuse installed for use with this equipment. If a power cable 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 fire and shock. Please read them carefully and heed all
warnings.
Installation
1. For best results, use your projector in a darkened room.
2. Place the projector on a flat, level surface in a dry area away from
dust and moisture.
3. Do not place your projector in direct sunlight, near heaters or heat
radiating appliances.
4. Exposure to direct sunlight, smoke or steam can harm internal components.
5. Handle your projector carefully. Dropping or jarring can damage internal components.
6. Do not place heavy objects on top of the projector.
7. If you wish to have the projector installed on the ceiling:
a. Do not attempt to install the projector yourself.
b. The projector must be installed by qualified technicians in order
to ensure proper operation and reduce the risk of bodily injury.
c. In addition, the ceiling must be strong enough to support the
projector and the installation must be in accordance with any
local building codes.
d. Please consult your dealer for more information.
E-2
Fire and Shock Precautions
1. Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of heat inside your projector. Allow
at least 3 inches (10 cm) of space between your projector and a
wall.
2. 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 projector. If something should fall into your projector, disconnect it immediately and have the object removed by a qualified
NEC service personnel.
3. Do not place any liquids on top of your projector.
4. Do not look into the lens while the projector is on. Serious damage
to your eyes could result.
5. 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.
6. Do not cover the lens with the supplied 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.
7. The projector is designed to operate on a power supply of 100-120
or 200-240 V 50/60 Hz AC. Ensure that your power supply fits this
requirement before attempting to use your projector.
8. Handle the power cable carefully and avoid excessive bending.
A damaged cord can cause electric shock or fire.
9. If the projector is not to be used for an extended period of time,
disconnect the plug from the power outlet.
10. Do not touch the power plug during a thunderstorm. Doing so can
cause electrical shock or fire.
CAUTION
1. Do not try to touch the ventilation outlet on the left side (when seen
from the front) as it can become heated while the projector is turned
on.
2. 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.
3. Enable High-Speed Fan mode if you continue to use the projector
for consecutive days. (From the menu, select [Advanced] → [High
Speed Fan Mode].)
4. Do not unplug the power cable from the wall outlet under any one of
the following circumstances.
Doing so can cause damage to the projector:
* While the Hour Glass icon appears.
* While the cooling fans are running. (The cooling fans continue
to work for 60 seconds after the projector is turned off).
Lamp Replacement
•To replace the lamp, follow all instructions provided on page E-25.
• 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 NEC dealer for lamp replacement.
• Allow a minimum of 60 seconds to elapse after turning off the projector. Then turn off the main power switch, disconnect the power
cable and allow 60 minutes to cool the projector before replacing
the lamp.
What's in the Box?
Make sure your box contains everything listed. If any pieces are missing, contact your dealer.
Please save the original box and packing materials if you ever need to
ship your VT46 Projector.

Setting Up the Screen and the Projector
Selecting a Location
The further your projector is from the screen or wall, the larger the image. The minimum size the image can be is approximately 21" (0.53 m)
measured diagonally when the projector is roughly 27.6 inches (0.7 m) from the wall or screen. The largest the image can be is 300" (7.6 m) when
the projector is about 393.7 inches (10 m) from the wall or screen. Use the drawing below as a guide.

WARNING
* Installing your projector on the ceiling must be done by a quali-
fied 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 32˚F (0˚C) and 95˚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. Contact your NEC dealer if you need a mirror. If
you're using a mirror and your image is inverted, use the MENU and
SELECT buttons on your projector cabinet or your remote control to
correct the orientation. (See page E-22.)

* If you accidentally hit the POWER (ON/STAND BY) button on the remote control, wait 60 seconds and then press the POWER (ON/STAND BY) button again to
resume.
