Precautions Notes on Handling and Storage • Do not store in locations with high temperatures or high humidity. It may in particular be damaged or deformed if left in a vehicle with the windows shut, or placed it locations with unusually high temperatures for extended periods such as in direct sunlight. • Do not get it wet. This may cause malfunctions to occur. • Do not use near microwave ovens. Wireless communication may be interrupted by electromagnetic interference generated by microwave ovens. • Do not drop it, subject it to shocks, or place heavy objects on it. Frequency Precautions The frequency band for this unit is 2.4 GHz/5 GHz. This frequency range is the same frequency bandwidth as industrial, scientific, and medical devices such as microwave ovens and mobile unit identification (RF-ID) systems (licensed premises radio stations and unlicensed specified lowpower radio stations) used in factory production lines. Before using this unit, check that there are no radio stations for mobile unit identification or specified low-power radio station premises nearby. In the event that this unit 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 your local dealer or the nearest address provided in the Support and Service Guide supplied with the projector if this unit interferes electromagnetically with a special lowpower radio station used for mobile unit identification or causes similar problems. 5 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 International Travel Precautions Wireless devices are designed to conform to the channel and frequency limits of the country they are intended to be used in. This unit is based on the specifications of the country of sale. If this unit is used outside the country of sale, check with a local dealer for more information. Precautions Notes on Security when Using Wireless LAN (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 authorization, 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. • Unauthorized 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. See the documentation supplied with the projector for information on security settings. 6 Installing this Unit Installing Install this unit into the projector. 7 losing this unit and so on, make sure you C Tofix avoid it in place with the screw supplied.

Type of Network Connection You can use the following two methods to connect a computer and the projector over a network by using EMP NS Connection found on the EPSON Projector Software for Meeting & Presentation CD-ROM supplied with the projector. f "Advanced Connection Mode" 9 When connecting in "Advanced Connection Mode" you can use the network in the following ways. • 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 projectors on a network from the computer. f "Quick Connection Mode" "Quick Connection Mode" is a mode for executing wireless LAN only. "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. "Advanced Connection Mode" is an infrastructure connection, and connects to an existing network system via a network cable. When this unit is installed in the projector, you can connect to a network via a wireless LAN access point. If the wireless LAN access point is WPS (Wi-Fi Protected Setup) compatible, you can easily connect the projector to the access point and make security settings. See the documentation supplied with the projector for more details. This unit Internet LAN Wi-Fi compliant wireless LAN card or wireless LAN enabled computer "Quick Connection Mode" has the following advantages. • You can easily connect a computer to the projector 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. This guide explains how to connect to a computer in "Quick Connection Mode" and project computer images. Steps for Connecting in "Quick Connection Mode" Steps before Connecting in "Quick Connection Mode" In the following illustration, you only need to perform the light blue sections the first time you connect.
