disc player or document camera to your projector.
To make these connections, simply:
1. Turn off the power to the projector and VCR, laser disc player or
document camera.
2. Connect one end of your RCA cable to the video output connector on
the back of your VCR or laser disc player, connect the other end to
the Video input on your projector. Use an audio cable (not supplied)
to connect the audio from your VCR or laser disc player to your audio
equipment (if your VCR or laser disc player has this capability). Be
careful to keep your right and left channel connections correct for
stereo sound.
3. Turn on the projector and the VCR or laser disc player.
NOTE: Refer to your VCR or laser disc player owners manual for more informa-tion about your equipments video output requirements.
NOTE: An image may not be displayed correctly when a Video or S-Video sourceis played back in fast-forward or fast-rewind via a scan converter.
Connecting the Supplied Power Cable
Connect the supplied power cable to the projector.
First connect the supplied power cables three-pin plug to

PROJECTING AN IMAGE (BASIC OPERATION)
This section describes how to turn on the projector and to project a
picture onto the screen.
Turning on the Projector
NOTE:
•When plugging in or unplugging the supplied power cable, make sure that the
main power switch is pushed to the off[O] position. Failure to do so may cause
damage to the projector.
•The projector has two power switches: main power switch and POWER button
(POWER ON and OFF on the remote control)
•The projector has a feature to prevent itself from being used by unauthorized
individuals. To use this feature, register your PC card as a protect key. See
Security in Projector Options on page E-53 for more details.
To turn on the main power to the projector, press the Main Power switch
to the ON position ( I ).
Before you turn on your projector, ensure that the computer or video
source is turned on and that your lens cap is removed.
Only after you press the ON/STAND BY button on the projector cabinet
or POWER ON button on the remote control for a minimum of 2 sec-
onds will the power indicator turn to green and the projector become
ready to use.
Note on Startup screen (Menu Language Select screen)
When you first turn on the projector, you will get the Startup screen. This
screen gives you the opportunity to select one of the seven menu lan-
guages: English, German, French, Italian, Spanish, Swedish and Japa-
nese.
To select a menu language, follow these steps:
1. Use the SELECT 
 or  button to select one of the seven languages
for the menu.

2. Press the ENTER button to execute the selection.
3. The Basic menu will be displayed in the language you have selected.
To close the menu, press the CANCEL button.
After this has been done, you can proceed to the advanced menu op-
eration.
If you want, you can select the menu language later. See Language
on page E-45.
NOTE: To turn the projector on by plugging in the power cable, first turn on the
Main Power switch to ON and use the menu and enable the Auto Start feature.
(See page E-47.) Immediately after turning on the projector, screen flicker may
occur. This is not a fault. Wait 3 to 5 minutes until the lamp lighting is stabilized.
When the Lamp mode is set to Eco, the Lamp indicator will light green.
If one of the following things happens, the projector will not turn on.
*If the internal temperature of the projector is too high, the projector
detects abnormal high temperature. In this condition the projector
will not turn on to protect the internal system. If this happens, wait for
the projectors internal components to cool down.
*When the lamp reaches its end of usable life, the projector will not
turn on. If this happens, replace the lamp.
*If the lamp fails to light, and if the STATUS indicator flashes on and
off in a cycle of six times, wait a full minute and then turn on the
power.

Focus
Use the FOCUS Button (+/-) to obtain the best focus.
Correcting the Horizontal and Vertical Key-
stone Distortion (3D Reform)
Use the 3D Reform feature to correct keystone (trapezoidal) distortion
to make the top or bottom and the left or right side of the screen longer
or shorter so that the projected image is rectangular.
In the following description, 3D Reform (Cornerstone) correction can be
done with the USB mouse or remote control, cabinet buttons.
Using Auto Focus
Press and hold the AUTO ADJUST button on the cabinet or AUTO ADJ
button on the remote control for a minimum of 2 seconds. The focus
pattern will be displayed for a moment and then the best focus will be
automatically obtained.
NOTE: The Auto Functions have two options: Focus and Wall Color Correction.
When the AUTO ADJUST or AUTO ADJ button is pressed and held for a mini-
mum of 2 seconds, either item can be executed. You can decide in advance
which item will be enabled at the time of execution.
From the Advanced menu, select [Projector Options] 
→ [Auto Functions]. Youcan turn on or off Focus and Wall Color Correction. See page E-49.
NOTE: Just pressing quickly the AUTO ADJUST button on the cabinet or AUTO
ADJ button on the remote control will enable the Auto Adjust feature instead of
the Auto Focus feature.
NOTE:
Geometric Correction Tool
If you use a special shaped screen such as a cylindrical or spherical screen, a
downloadable program, Geometric Correction Tool is available.
This program (Geometric Correction Tool) enables the geometrical distortion
correction of an image when projected onto a special shaped screen with an NEC
projector. Additionally, this program allows control of the projector via a com-
puter.

AUTO ADJ.
Press the Auto Adjust button to fine-tune the computer image or to re-
move any vertical banding that might appear and to reduce video noise,
dot interference or cross talk (this is evident when part of your image
appears to be shimmering). This function adjusts the clock frequencies
that eliminate the horizontal banding in the image. This function also
adjusts the clock phase to reduce video noise, dot interference or cross
talk. (This is evident when part of your image appears to be shimmer-
ing.)
This adjustment may be necessary when you connect your computer
for the first time.
NOTE:
•Some signals may not be displayed correctly or take time.
•The Auto Adjust function does not work for component and video signal.
•If the Auto Adjust operation cannot optimize the RGB signal, try to adjust Clock
and Phase manually. See page E-41.
•Pressing and holding the AUTO ADJUST button on the cabinet or AUTO ADJ
button on the remote control for a minimum of 2 seconds will enable the Auto
Focus and the Auto Wall Color Correction feature instead of the Auto Adjust
feature.
NOTE: During 3D Reform adjustment, Aspect Ratio and Screen may not be
available. Should this happen, first reset the 3D Reform data and then do each
setting. Second repeat the 3D Reform adjustment. Changing Aspect Ratio and/
or Screen setting can limit 3D Reform in its adjustable range.
The adjustable ranges for 3D Reform are as follows:
Horizontal ........... Max ±35° approx.
Vertical ............... Max +50°/-25° approx.
*The following are conditions at the above maximum angle when all of
the following are met
•Image is projected in Wide (Zoom)
•Resolution is XGA
Higher resolution than XGA limits 3D Reform in its adjustable range.
•Menu items should be set as follows:
Aspect Ratio ............................... 4:3
Screen Type ................................ 4:3
•Horizontal and Vertical are adjusted separately.
A combination of both adjustments limits 3D Reform in its adjustable
range.
•When 4:3 Fill is selected in Aspect Ratio, Cornerstone and Hori-
zontal Keystone are not available.
Turning Up or Down Volume
Sound level from the speaker and the AUDIO OUT jack (RCA) on the
projector can be adjusted.

Auto 3D ReformAuto 3D Reform automatically corrects distortion by sensing the outline
or outer frame of your screen with the projector’s built-in image sensor
to project an image within the screen.
NOTE:
•The Auto 3D Reform feature supports screen sizes between 30” and 200”.
•If the screen has the same brightness as its background, the built-in image
sensor on the front of the projector can fail to recognize the outline or outer
frame of the screen.
Should this happen, the Auto 3D Reform feature cannot function.
If irregular colors, flaw or change of color are seen on the screen, the built-in
sensor can mistakenly interpret the outline or outer frame of the screen.
•If there is an object between the built-in sensor and the screen, the screen
cannot be recognized.
•The Auto 3D Reform feature does not support reflective screens. Matt type or
beads type screens are recommended.
Executing the Auto 3D Reform feature
1. Project an image.
See the user’s manual or the quick connect guide for projecting an
image.
2. Press the 3D REFORM button.
