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.

When a setting error for the wireless LAN card has been detected

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.

**Note: 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.)

When the Network Bridge setting has been detected

Is Network Bridge enabled?
Some computers with Windows XP may have Network Bridge (a built-in function of Windows XP) enabled; this will prevent a wireless connection. The settings in Network Bridge must be changed in order to make a wireless connection. If you do not expect ever to use Network Bridge and see no need for it, delete it from your system.

To verify whether your system has Network Bridge

Choose [Connect to] on the [Start] menu and click [Show all connections]. Verify that [Network Bridge] is displayed in the [Network Connections] window.

How to change settings in Network Bridge

1. Select [Connect to] on the [Start] menu and click [Show all connections].
2. Right-click [Network Bridge] and click [Properties].
3. Remove the check mark from the [Wireless Network Connection] box in the [Network Bridge Properties] dialog box (if the box is not checked, proceed to step 4.
4. Click [Properties] in [Internet Protocol (TCP/IP)] in the [Network Bridge Properties] dialog box.
5. Click the [Alternate Configuration] tab in the [Internet protocol (TCP/IP) properties] dialog box.
6. Check the [User configured] box and set the [IP address] and [Subnet mask] as follows:
   IP address : 10. 10. 10. 101
   Subnet mask : 255. 255. 0. 0
   (If the above IP address is already in use in the LAN environment, change it as appropriate in Class A. Confirm to your system administrator on network settings before changing any settings.)
7. Click [OK] → [Close].
8. Close the [Network Connections] dialog box.

How to delete the network bridge

1. Select [Connect to] on the [Start] menu and click [Show all connections].
2. Right-click [Network Bridge] and click [Delete].

7. Select the scope and click [OK].
8. Click [OK] in the [Add a Program] window.
9. Click [OK] in the [Windows Firewall] window. With this, the Wireless Manager ME 3.0 firewall will be deleted.

When another firewall has been detected

Are any firewall-containing applications installed?
If any applications that 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.

When the user does not have the administrator authority

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.

Network setting error
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

• 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.

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 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.

• 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.

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.

• 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.

• Basically, files which can be played on Windows Media Player can be displayed with this projector. However, contents protected by DRM※ cannot be projected nor can such DVDs be played.

DRM (Digital Rights Management): Technology for protecting the copyrights of digital data

Connected computers’ names, IDs and their status are displayed in the pop up window when the cursor is on [ ] of the launcher.

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.

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.

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)

• 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.

• When easy wireless set up connection is used:
  When any WebBrowser except Internet Explorer is used, the proxy settings of the WebBrowser must be manually released.
• When [USER] connection is used:
  Manually release the proxy settings of the WebBrowser used.
