Frequently Asked Questions
Check the following points once more before requesting repair.
No wireless connection can be made between my projector and my computer.
• Is Wireless Manager ME 3.0 running?
    Wireless  Manager  ME  3.0  must  be  started  in  the  computer  in  order  to  enable  wireless transmissions of images to the projector.

ƒ Is the wireless LAN card effective? Even  if  your  computer  has  built-in  wireless  LAN,  the  wireless  LAN  may  still  be 
turned  OFF.  If  so,  turn  it  ON  and  re-start  Wireless  Manager  ME  3.0.  See  the 
User’s  Manual  of  your  computer  to  learn  how  to  turn  the  wireless  LAN  power 
ON/OFF.
„ Is your wireless LAN card properly recognized on the network? Sometimes,  cards  are  not  correctly  recognized  by  the  computer.  Check 
Windows [Device Manager] to make sure your card has been recognized.
 If  the  Network Adapter  is  indicated  with  [?]  in  [Device  Manager],  wireless  LAN 
card  installation  is  not  complete.  See  the  User’s  Manual  of  your  card  and  re-
install the card driver.
 To display [Device Manager]
 Click [Start] → [Control Panel] → [Performance and Maintenance] → [System]. 
This will bring up the [System Properties] dialog box. Click [Device Manager] in 
the [Hardware] tab.
…   Some wireless LAN cards may allow easy wireless set up connections to 
function if drivers are updated.
(Consult the manufacturer of your driver about updates.)

Frequently Asked Questions (cont.)
No wireless connection can be made between my projector and my computer. (cont.)

Are any firewall-containing applications installed? 
 If  any  applications  which  contain  firewalls  are  installed,  the  installation  may  hang 
up at the [Projector search in progress] display (some firewalls function even when 
not started).
If this occurs, firewall settings must be changed in order to allow connection to the 
wireless  network.  See  the  User’s  Manuals  for  all  applications  containing  firewalls 
to perform these settings.

Have you logged in as the Administrator?If  you  have  logged  onto  a  computer  as  a  [GUEST]  or  a  restricted  user  who 
does  not  have  administrator  authority,  you  can  not  perform  easy  wireless  set 
up  (Network  No.  [1]  –  [4]).  If  you  must  perform  easy  wireless  set  up  without 
administrator authority, designate [U] as the network number.
See page 49 or 51 for instructions in how to set [U] as the network number .

When connecting with Network number [U], make sure whether wireless menu  
setting of the projector is correct or not. (See page 49)
Wireless connection is lost shortly.
ƒ  The wireless LAN utility used by the computer may have changed the wireless  settings.  Close  the  utility,  and  then  make  the  connection  again  using  easy 
wireless set up connection.
„  Connection  may  be  broken  receiving  influence  from  wireless  environment 
around.
…   When connection is  broken, PT-LB50NT/PT-LB55NT/PT-LB60NT automatically 
work to reconnect, but when it can not, live is cancelled. 
When live is cancelled with PT-LB50NT/PT-LB55NT/PT-LB60NT or connection 
is  broken  with  projectors  other  than  PT-LB50NT/PT-LB55NT/PT-LB60NT,  start 
live from the launcher again.

Frequently Asked Questions (cont.)
The connection has been lost in the multi live mode.•  If  a  computer  with  a  certain  version  of  the  Intel  Centrino  mobile  technology (wireless  LAN)  is  connected  to  the  unit,  the  multi  live  mode  may  be  released. 
If  this  is  the  case,  re-establish  the  connection  from  the  launcher  of  Wireless 
Manager ME 3.0. (See page 23)
The connection cannot be established with IEEE802.11 g. •  Connection  is  sometimes  established  under  the  IEEE802.11  b  standard  even when  an  IEEE802.11  g  wireless  LAN  card  or  a  computer  with  built-in  wireless 
LAN that supports the IEEE802.11 g standard is used. This is, therefore, not an 
indication of trouble.
The transfer rate is slow. •  The transfer rate may be slower in some operating environments (depending on 
such factors as the location, radio signal conditions or distance).
•  Avoid  placing  metal  objects  or  other  conductors  near  the  wireless  LAN  antenna  of a personal computer, otherwise the transfer rate may be slower.
• When WEP is set the image data is converted, so transfer takes time.
Image display is slow or movie/animation is not displayed smoothly .
• Is the computer CPU speed slow? (See page 9)
  Live mode depends largely upon the computer CPU performance.
•  Adverse  effects  may  be  exerted  if  there  is  any  wireless  communication  in  the  vicinity.
•  
  When  [Resolution]  is  set  to  [High  Definition]  in  the  “Option”  window,  it  may  take 
longer time to display images.
•  
 
The Windows Media Player window should be active.
•  
 
Did  you  start  up  Microsoft  PowerPoint  or  Windows  Media  Player  before  starting 
up Wireless Manager ME 3.0?
   If  so,  start  up  the  application  only  after  you  have  started  up  Wireless  Manager 
ME 3.0.
•  The  speed  may  drop  significantly  if  the  user  does  not  have  administrator  authority.
•  
 
The speed may be slower when any other applications are running concurrently .

Frequently Asked Questions (cont.)
There is a time lag between operations at the computer and results in the projected image.
•  Wireless Manager ME 3.0 reads the screen, compresses the data and transmits it  to  the  projector.  In  the  projector,  the  received  data  are  extracted  and  then 
projected.  Some  delays  occur  in  this  system,  due  to  the  processing  time  and 
factors  in  the  wireless  environment.  Different  computers  may  also  produce 
varying lag times.
I can’t hear the computer sound from the projector in the live mode.
•  Check  whether  the  check  mark  has  been  entered  for  [Produce  audio  along with  video  at  live  mode]  from  [Live  Mode  Settings]  under  the  [Transmission]  tab 
selected from Wireless Manager ME 3.0’s “Option” window.
•  Did  you  start  up  a  player  (Windows  Media  Player,  Real  Player  or  Quick  Time, 
etc.) before starting live mode?
   If so, start the application only after starting live mode.
Some contents in movies are not displayed.
•  Basically, files which can be played on Windows Media Player can be displayed
 
with  this  projector.  However,  contents  protected  by  DRMÞ  cannot  be  projected 
nor can such DVDs be played.
  Þ  DRM (Digital Rights Management):  Technology  for  protecting  the  copyrights 
of digital data
Don’t know to which projector the computer is connected in multiple source live mode or multiple source multi live mode.
•  Connected  computers’  names,  IDs  and  their  status  are  displayed  in  the  pop  up 
window when the cursor is on [] of the launcher.

Frequently Asked Questions (cont.)
Changing the display style•  Either  press  the  [MULTI-LIVE  SELECT]  button  on  the  remote  control  or  select [OPTION] → [DETAILED SETUP] → [INDEX WINDOW] on the projector’s main 
menu (See page 45) and press the [ENTER] button.
The Wireless Manager ME 3.0 color display is strange and characters are difficult to read.
•  Click  [Start]  →  [Control  panel]  →  [Appearance  and Themes]  →  [Display]. Then, 
open the [Settings] tab of the [Display Properties] window and set [Color quality] 
to [Medium (16 bit)] or higher.
Screen saver is not displayed properly in live mode.
•  Some screen savers may not be displayed properly in the live mode.
   Disable  screen  saver  function  using  [Live  Mode  Settings]  in  “Option”  window  of 
Wireless Manager ME 3.0. (See page 42)
Making a wireless connection while using the internet•  If  you  have  a  wireless  LAN  environment  which  allows  an  internet  connection, placing  the  projector  on  that  network  will  allow  you  to  use  the  internet  and  the 
wireless connection at the same time. (See page 19)
•  If you have a wired internet connection (Ethernet), this projector allows wireless 
use with simultaneous wired connection to the internet.
The remote control window does not appear.

•  When  any  WebBrowser  except  Internet  Explorer  is  used,  the  proxy  settings  of  the WebBrowser must be manually released.

•  Manually release the proxy settings of the WebBrowser used.
