•Is Network Bridge enabled?
Some PCs 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.)
7. Click [OK] →[Close].
8. Close the [Network Connections] dialog box.
How to delete the network bridge

•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 running Windows 2000 or Windows XP as a
guest, who does not have the privileges of an Administrator, you can not
perform a simple connection (Network No. 1 – 4). If you must perform wireless
connection while logged in as a guest, designate [USER] as the network
number.
See page 29 or 32 for instructions in how to set [USER] as the network number.
Alternatively, log in as the Administrator and set the Hardware acceleration to
[None].
How to set the Hardware acceleration to [None]
(may not be applicable in all computers)
1. Click [Settings] tab in the [Display Properties] dialog box.
2. Click [Advanced] and select the [Troubleshoot] tab in the resulting dialog box.
The Hardware acceleration settings menu will be displayed.
3. Move the lever all the way to the left end ([None]) and click [Apply].
Note that when you have set the Hardware acceleration to [None], image
transfer functions are degraded.
•I can connect with the projector using the simple connection, but then the
connection is lost shortly afterward.
The wireless LAN utility used by the computer may have changed the wireless
settings. Close the utility, and then make the connection again using the simple
connection.

Frequently Asked Questions(cont.)
The launcher is displayed in the projection screen.
•The launcher is projected in the projection screen of the projector in Windows
98SE/Me. If you do not want this shown, click [ ] in the launcher. This stores
the launcher in the task tray.
There is a time lag between operations at the computer and results in the projected image.
•Wireless Manager mobile edition 2.0 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.
PowerPoint animations are not displayed smoothly.
•There are some variations in playability of animations depending on computer
capabilities; some animation effects are not completely reproduced. If you wish
to run PowerPoint animations, we recommend creating them in advance and
trying them out on your projector.
Supported operating systems
•This projector is supported on Windows 98SE/Me/2000 Professional/XP Home
Edition/XP Professional.
It is not compatible with any other systems.
Moving picture transmission does not function with Windows 98SE or Windows
Me.
Changing the display style
•The projector is designed to provide three display styles: standard style, 4-
screen index style, and 16-screen index style.
Press the [INDEX WINDOW] button on the remote control to toggle between
styles, or select [INDEX WINDOW] on the projector’s main menu (see page 28)
and press the [ENTER] button.
When the style is changed, the connection between the computer and the
projector is canceled.

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 options.

2
7. Upon completion of the above settings, start playing an audio file, for
example, check that sound is heard from the computer, go live, and check
whether the sound is output from the projector.
2 The control selected here differs depending on the operating system and
environment used. Try selecting another control if [Stereo Mixer] is not
available or the sound is not output even after selecting [Stereo Mixer].
•The playability of movies depends on the capability of the computer you are
using and on the wireless environment. We recommend using the powerful
computer available when projecting a movie. Wireless reception is disrupted
when other wireless equipment is operating nearby; it should be turned off when
using the projector.
•
In the live mode, operation will slow down also when the Windows Media Player
window is not active. Select this window before playing a movie. However,
operation may be delayed with some materials even when the Windows Media
Player window is set to active.
•Basically, files which can be viewed on Windows Media Player can be viewed
with this projector. However, contents protected by DRM1cannot be projected
nor can such DVDs be played.

Frequently Asked Questions(cont.)
Making a wireless connection while using the internet
The remote control window does not appear.
•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. 
•If you use a simple connection with two wireless LAN cards, since which card to
be used for the projector will not be clear, you must make the connection
between the computer and the projector through the user settings (manually).
•If you have a wired internet connection (Ethernet), this projector allows wireless
use with simultaneous wired connection to the internet.

•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.
The connection has been lost in the multi live mode.
•If a computer with a certain version of the Centrino 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 2.0. (See
pages 19 to 21.)
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.
