Notes When Using a Wireless LAN 5 Conditions for Connecting to Compatible Wireless LAN Cards and Access Points The supplied wireless LAN unit can be connected to the following products in accordance with IEEE 802.11g, 802.11b, and 802.11a. • Wireless LAN card • Computers with a built-in wireless LAN function • Access points However, you are unlikely to be able to make an ad hoc connection for wireless LAN equipment used with a computer in IEEE 802.11g. For details on wireless LAN equipment see the specifications. Supplied Wireless LAN Unit Specifications Frequency Range Modulation Potential Interference Range Propriety of Frequency Change IEEE 802.11b/g: 2.4 GHz band (1 to 11 Ch), IEEE 802.11a: 5.2 GHz band (W52), 5.3 GHz band (W53)* IEEE 802.11b : DS-SS IEEE 802.11a/g: OFDM Less than 20 m Can use all bands, and can avoid "licensed" and "unlicensed" bands. * You can only connect to the 5.3 GHz band (W53) using Advanced Connection. 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.
