Can use all bands, and can avoid "licensed" and "unlicensed" bands.

Electromagnetic Safety Precautions

Be aware of the following points when using the supplied wireless LAN unit.
• May exert electromagnetic interference on, and cause malfunction of, cardiac pacemakers. Before use, ensure that electromagnetic interference does not occur.
• May exert electromagnetic interference on, and cause malfunction of, sensitive medical equipment. Before use, ensure that electromagnetic interference does not occur.
• Do not use near microwave ovens. Wireless communication may be interrupted by electromagnetic interference generated by microwave ovens.
• Use of this product on aircraft may be restricted in some countries. Use of this product is based on due diligence with regard to regulations.

Frequency Use Precautions

The frequency band for the wireless LAN unit that is included with the projector is 2.4 GHz/5 GHz. This band is used for industrial, scientific, and medical devices such as microwave ovens, and it is also used by premises radio stations for mobile unit identification (RF-ID) systems in the factory line (license required) and specified low-power radio stations (no license required). Before using the wireless LAN, check that there are no radio stations for mobile unit identification or specified low-power radio station premises nearby. In the event that this wireless LAN should interfere electromagnetically with the premises of a radio station used for mobile unit recognition, cease use immediately and stop generating the electromagnetic field. Contact Epson as described in your User’s Guide if this wireless LAN interferes electromagnetically with a special low-power radio station used for mobile unit identification or causes similar problems.
Notes When Using a Wireless LAN

International Travel Precautions

Wireless LAN units are based on the specifications of the country of purchase. The wireless LAN unit is designed to conform to the channel and frequency limits of the country it is intended to be used in. If the wireless LAN unit is used outside the country of purchase, check with a local dealer for more information.

Wireless Telegraphy Act Regulations

The following acts are prohibited by the Wireless Telegraphy Act.
• Modifying and disassembling (including the antenna)
• Removing the label of conformance
• IEEE 802.11a (5 GHz band) external use

Notes on Security when Using Wireless LANs

(Important information on customer rights (maintaining privacy))
The advantage of using a wireless LAN over a LAN cable is that, because information is exchanged using radio signals, you can easily connect to the network if you are within range of the radio signals. A disadvantage of this is that within a certain range, the electromagnetic signals can pass through barriers such as walls, so that if security countermeasures are not implemented in some way, problems such as the following may occur.
• Communicated data can be intercepted A third party may be able to receive wireless transmissions without authorisation, and they could obtain personal information from these transmissions such as IDs, passwords, or credit card numbers, or they could intercept the contents of personal e-mail messages.
• Unauthorised access to the network A third party could access an individual or intra-company network without permission and carry out any of the following activities.
• Retrieve personal data or other secret information (information leakage)
• Pose as another user and send inappropriate data (impersonation)
• Overwrite the contents of intercepted data and resend it (falsification)
• Introduce a computer virus which could cause data loss or system crashes (damage)
Initially, the possibility that such problems could occur through settings concerning the security of the wireless LAN product and by using the product are decreased, because the wireless LAN card and the access point have security measures to deal with these problems. We recommend that you use this product after making security settings using your own judgment and assuming full responsibility, and with your full understanding of problems that may occur if you do not make any security settings.

Connecting with Quick Wireless Connection

You can use the supplied Quick Wireless Connection USB key (hereafter "USB key") to project images from a connected Windows computer. This function is called Quick Wireless Connection. You can quickly project images by connecting the USB key to the computer. Software requirements are listed in the appendix. s p.97

Overview of EMP NS Connection

13
There are two methods of connecting the projector and a computer via a network by using EMP NS Connection.

Two Connection Modes and their Main Functions

f "Quick Connection Mode" (only when the "Wireless LAN
unit" is installed)
"Quick Connection Mode" only runs when you install the supplied "Wireless LAN unit" in the projector. "Quick connection mode" temporarily assigns the projector's SSID to a computer creating an ad hoc connection, and after disconnecting restores the computer's network settings. s p.16
f "Advanced Connection Mode"
"Advanced Connection Mode" is an infrastructure connection, and connects to an existing network system via a network cable. If you install the supplied "Wireless LAN unit" in the projector, you can connect to the network via a wireless LAN access point. If you install the optional "Ethernet unit" you can connect to a network without an access point. When connecting to a network via the Ethernet unit, connect the projector to the network hub with a commercially available LAN cable.
Internet

Wi-Fi compliant wireless LAN card or wireless LAN enabled computer
• You can easily connect to a computer and project images from the computer without making network settings.
• This lets you connect easily without a connector cable, and you can connect even if the projector and the computer are at remote locations.
• From a conference room, you can open and project a file stored on a computer or file server in another room.
• You can use the Internet.
• You can monitor and control projector's on a network from the computer.
Overview of EMP NS Connection
f Main functions
The following convenient functions let you make various meetings and presentations.
• Multi-Screen Display sp.28 You can project different images from one computer to a maximum of four projectors, allowing you to project landscape images such as reports.
Internet
14
• Movie file transfer (Movie Sending Mode) s p.26 By using "Movie Sending Mode", a movie can be projected much smoother than when it is being sent from an application running on a PC. Because the audio is sent at the same time as the movie, you do not need to connect the computer and the projector with an audio cable.
• Presentation mode s p.25 This function can project PowerPoint slide shows running on a computer. You can give stylish presentations by projecting a black screen while making preparations or when not performing a slide show and so on.
• Distribution function The screen being displayed by a remote computer can be simultaneously displayed by up to four projectors with corresponding SSID.
• Switching function By using the meeting switching function, if EMP NS Connection is installed on all of the computers, the presenters can take turns and project their own images without changing cables.

Projecting Movies from a Computer (Movie Sending Mode)

26
In Movie Sending Mode, movie files can be sent directly to a projector. As a result, a movie can be projected much more smoother than when it is being sent from an application running on a PC. Also, because the audio is sent at the same time as the movie, there is no need for an audio cable between the computer and the projector.
• Movie Sending Mode is valid for one projector only. It is
q
not possible to apply Movie Sending Mode to more than one projector.
• Depending on the communication method and the available reception, the image and sound may skip or stall.

Using Multi-Screen Display

Multi-screen display mode allows you to project different images from multiple projectors that are connected to a single computer. With Windows, multiple virtual displays can be set in the computer, and each image can be projected by the projector. This function is not available with Windows Vista due to restrictions in the Windows Vista specifications. For the Macintosh, an external monitor must be connected to the computer to enable the use of the multi-screen display function. Whereas the above explanation has referred to "virtual display", in the case of the Macintosh, the operation relates to the screens displayed on the physically connected monitor.

Example of Adjusting the Virtual Display

By arranging the virtual display allocation, you can project only the image that you want to show when making a presentation or project different images from left to right.
