Important Information
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 4 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 100-240V AC 50/60 Hz. 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.
11. Do not handle the power plug with wet hands.
12. When using a LAN cable:
For safety, do not connect to the connector for peripheral device wiring that might have excessive voltage.
CAUTION
• Do not try to touch the ventilation outlet on the front side as it can become heated while the projector is turned
on.
• Do not 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.
• Before putting the projector in the soft carrying case, be sure to retract the feet. Failure to do so may cause the
damage to the projector.
• Do not send the projector in the soft carrying case by parcel delivery service or cargo shipment. The projector
inside the soft carrying 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] → [Fan Mode] → [High].)
• 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 projector's lamp lights.
* While the cooling fans are running. (The cooling fans continue to work for 90 seconds after the projector is
turned off).
* While the PC CARD Access Indicator lights. Doing so can damage your PC memory card.

Remote sensor on projector cabinet
• The infrared signal operates by line-of-sight up to a distance of about 22 feet/7 m and within a 60-degree angle of
the remote sensor on the projector cabinet.
• The projector will not respond if there are objects between the remote control and the sensor, or if strong light falls
on the sensor.
Weak batteries will also prevent the remote control from properly operating the projector.
Remote Control Precautions
• Handle the remote control carefully.
• If the remote control gets wet, wipe it dry immediately.
•Avoid excessive heat and humidity.
• If you will not be using the remote control for a long time, remove the batteries.
• Do not place the batteries upside down.
• Do not use new and old batteries together, or use different types of batteries together.
• Dispose of used batteries according to your local regulations.

2. Installation and Connections
WARNING
* Installing your projector on the ceiling must be done
by a qualified 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 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 system. If you're using a mirror system 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 98.

2. Installation and Connections
Making Connections
NOTE: When using with a notebook PC, be sure to connect between the projector and the notebook PC before turning on the
power to the notebook PC. In most cases signal cannot be output from RGB output unless the notebook PC is turned on after
connecting with the projector.
* If the screen goes blank while using your remote control, it may be the result of the computer's screen-saver or power
management software.
Enabling the computer’s external display
Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projector.
When using a PC compatible laptop, a combination of function keys will enable/disable the external display.
Usually, the combination of the ‘Fn” key along with one of the 12 function keys gets the external display to come on
or off. For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle through
external display selections.

2. Installation and Connections
NOTE: The LT265/LT245 is not compatible with video decoded outputs of either the NEC ISS-6020 and ISS-6010 switchers.
NOTE: An image may not be displayed correctly when a Video or S-Video source is played back via a commercially available scan
converter.
This is because the projector will process a video signal as a computer signal at the default setting. In that case, do the following.
* When an image is displayed with the lower and upper black portion of the screen or a dark image is not displayed correctly:
Project an image to fill the screen and then press the AUTO ADJ button on the remote control or the AUTO ADJUST button on
the projector cabinet.
* When noise appears on the sides of the screen:
Use the Overscan feature to display the image correctly.
Be sure to change the Overscan to 0% before pressing the AUTO ADJ or AUTO ADJUST button, otherwise an image may be
displayed with its sides cut off.
