Notes When Using a Wireless LAN

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.

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.
