Page 1

This equipment has been tested and found to comply with the limits for a Class B digital device,pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one of the following measures:

- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.

FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.

The device has been evaluated to meet general RF exposure requirement. The device can be used in
portable exposure condition without RF striction.

Thank you for purchasing the IEEE 802.11b/g or 802.11n Wireless USB Adapter. This

Wireless Adapter is easy to use and easy to setup. If you have been tired of dealing with all
those messy wires to connect a laptop or PC to office or home network, this Wireless adapter is
an ideal access solution for wireless Internet connection.

A typical Internet access application for the USB wireless adapter is shown as the following

figure:

There are two different ways to access Internet:

1) With a wireless adaptor, receiving and transferring signal via a wireless router, then passed

to an ADSL modem, then to local ISP (Internet service supplier) through a telephone line.

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled 
environment. End user must follow the specific operating instructions for satisfying 
RF exposure compliance. This transmitter must not be co-located or operating in 
conjunction with any other antenna or transmitter.
The mobile device is designed to meet the requirements for
exposure to radio waves established by the Federal Communications
Commission (USA). These requirements set a SAR limit of 1.6 W/kg
averaged over one gram of tissue. The highest SAR value reported under
this standard during product certification for use when properly worn on the body is 0.515 W/kg.

this standard during product certification for use when properly worn on the body is 0.75 W/kg.
