Connecting to a Network
The  NP3250/NP2250/NP1250/NP3250W  comes  standard  with  a  LAN  port  (RJ-45)  which  provides  a  LAN  connec-
tion  using  a  LAN  cable. The  USB Wireless  LAN  Unit  also  provides  a  wireless  LAN  connection. To  use  a  LAN  con-
nection, you are required to assign an IP address to the projector. For setting the NETWORK, see page 110. (From 
the menu, select [SETUP] → [INSTALLATION(2)] → [NETWORK SETTINGS])
NOTE: Some projectors may not have the USB Wireless LAN Unit. If you own a projector without the USB Wireless LAN Unit in-
stalled and need to present to the projector via a wireless connection, \
the optional USB Wireless LAN Unit must be installed.
With the LAN connection, two features are available: Projector control and Picture transmission.
Projector control feature
With the wired or wireless LAN connection, you can control (power on/off, input select, etc.) and receive information 
from the projector over the network using a computer. The following three methods are available:
* Using the HTTP Server feature on the projector. (→ page 53)
* Using PC Control Utility 3.0 from the supplied User Supportware 6 CD-ROM.
* Using Image Express Utility 2.0 from the supplied User Supportware 6 CD-ROM.
Picture transmission feature (Using WindowsVista)
A Windows Vista-based  computer  can  be  operated  using  the  projector  over  a  network. The  projector  supports  the 
Network Projector function and the Remote Desktop function of Windows Vista. (→ page 56, 60)
Picture transmission feature (Using User Supportware  CD-ROM)
With  the  wired  or  wireless  LAN  connection,  you  can  send  images  and  slides  from  a  personal  computer  to  the  pro-
jector which then can be projected on the screen. The following two methods are available:
* Using Image Express Utility 2.0 from the supplied User Supportware 6 CD-ROM.
* Using ArcSoft MediaImpression from the supplied User Supportware 6 CD-ROM.
With  the  USB  mouse  connected  to  the  projector,  you  can  also  operate  the  desktop  screen  on  your  Windows  PC 
connected to the LAN or the wireless LAN.
* Using Desktop Control Utility 1.0 from the supplied User Supportware 6 CD-ROM.
TIP: Five  Windows  software  programs  (Image  Express  Utility  2.0,  Desktop  Control  Utility  1.0,  ArcSoft  MediaImpression,  Viewer 
PPT  Converter  and  PC  Control  Utility  3.0)  and  a  Macintosh  software  program  (Image  Express  Utility  2  for  Mac  OS  X)  are  con-
tained  on  the  supplied  Projector  User  Supportware  6  CD-ROM.  For  their  functions  and  operations,  see  the  user’s  guides  (PDF) 
contained on the same CD-ROM.
• For  the  procedure  to  connect  the  projector  with  the  network  (wireless  LAN/wired  LAN),  refer  to  “Wired  and 
Wireless Network Setup Guide” attached. 
• For  the  procedure  to  connect Windows Vista  with  the  network  (wireless  LAN/wired  LAN),  refer  to  the  manual 
of Windows Vista.
Viewer function supporting network
* Using the Viewer function, image and movie files stored in a shared folder in a computer connected to a net-
work can be projected. (→ page 73)
* The Viewer supports the “Media Sharing” function in Windows Media Player 11. (→ page 77)
NOTE: A LAN card on your computer must be compatible with Wi-Fi (IEEE80\
2.11a/b/g) standard.

NOTE: To turn off the AC power supply when the projector is powered on, use a p\
ower strip equipped with a switch and a breaker.
CAUTION:
Do  not  try  to  touch  the  ventilation  outlet  on  the  left  front  (when  seen  from  the  front)  as  it  can  become  heated 
while the projector is turned on and immediately after the projector is turned off.
CAUTION:
Do not unplug the power cable from the wall outlet or projector when the projector is powered on. Doing so can 
cause damage to the AC IN connector of the projector and (or) the prong plug of the power cable.
About Direct Power Off
The projector has a feature called “Direct Power Off ”. This feature allows the projector to be turned off (even when 
projecting an image) using the Main Power Switch or disconnecting the AC power supply.
NOTE: Before using Direct Power Off, be sure to allow at least 20 minutes immediately after turning on the projector and starting 
to display an image.

3. 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:
• The projector has two power switches: a main power switch and a POWER (ON/STAND BY) button (POWER ON and OFF on the 
remote control).
• When plugging in or unplugging the supplied power cable, make sure that the main power switch is pushed to the off () po-
sition. Failure to do so may cause damage to the projector.
• The  projector  has  a  feature  to  prevent  itself  from  being  used  by  unauthorized  individuals.  To  use  this  feature,  register  a  key-
word. (→ page 45)
1. Remove the lens cap.
•  Do  not  tr y  to  remove  the  lens  cap  by  pulling  on  the 
string. Doing so can cause damage.
2. To turn on the main power to the projector, press the 
Main Power switch to the on position ( I ).
•  The projector will go into standby mode. When in stand-
by mode, the POWER indicator will light orange and the 
STATUS indicator will light green.
3. After  making  sure  that  the  projector  is  in  standby 
mode,  press  the  POWER  (ON/STAND  BY)  or  POWER 
(ON)  button  for  a  minimum  of  2  seconds  when  the 
STATUS indicator goes off and the POWER indicator 
starts blinking.
  When  the  POWER  indicator  turns  a  steady  green, 
and the projector is ready to use.
•  After you turn on your projector, ensure that the comput-
er or video source is turned on and that your lens cap is 
removed.
NOTE: When no signal is available, a blue, black or logo screen is displ\
ayed.

3. Projecting an Image (Basic Operation)
Note on Startup screen (Menu Language Select screen)
When  you  first  turn  on  the  projector,  you  will  get  the  Startup  menu. This  menu  gives  you  the  opportunity  to  select 
one of the 21 menu languages.
To select a menu language, follow these steps:
1. Use the SELECT  button to select one of the 21 lan-
guages for the menu.
2.  Press the ENTER button to execute the selection.
After  this  has  been  done,  you  can  proceed  to  the  menu 
operation.
If  you  want,  you  can  select  the  menu  language  later.  (→ 
[LANGUAGE] on page 105)
NOTE:
•  The projector cannot be turned off for 60 seconds after the lamp is turn\
ed on and while the POWER indicator is blinking green.
• If you turn on the projector immediately after the lamp is turned off or when the ambient temperature is high, the cooling fans 
will run for a moment and then you will get an image on the screen.
• Immediately after turning on the projector, screen flicker may occur. This is normal. 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  projector’s 
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.
 (→ page 136)
- 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.
NOTE: Turning the Main Power Switch Off then Back On 
Allow a minimum of one second between turning off the main power switch \
and turning it back on again.
The same will be applied when a power strip equipped with a switch and a\
 breaker is used.
Failing to do so could result in no power to the projector. (There will be no stand-by LED) 
Should this happen, unplug the power cable and plug it in again. Turn on the main power switch.
