interference to radio or television reception, which can be determined by
turning off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
? Reorient or relocate the receiving antenna.
? Increase the distance between the equipment and receiver.
? Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
CAUTION:
1) To comply with FCC RF exposure compliance requirements, a separation

Introduction
A wireless LAN links network users to LAN services without the hassle
of cabling or wiring, which significantly brings mobile workers the
freedom of staying connected to the network while roaming around a
building or multiple buildings maintaining access to the Internet, e-mail,
networked applications, and print services.
This device is the perfect solution for your wireless network applications
based on the IEEE 802.11b standard that offers a data rate up to 11Mbps
in a wireless LAN environment. It is a high-speed wireless network card
that plugs into your notebook or desktop PC and accesses to the LAN or
peer-to-peer networking easily without wires or cables. Whether you’re
at your desk or in the boardroom, it allows you to share printers, files,
and other network resources.
The USB adapter is designed for a USB type A port of a laptop or
desktop computer for creating a wireless workstation.
