Introduction

Thanks for purchasing Radicom Res Module. Radicom is committed to
providing quality service and technical support in order to expedite the product
development process. The WiFiHU2 Module requires only a USB (Universal Serial Bus)
interface to add state of the art data WiFi wireless operation to any system. It is designed

to fully support IEEE802.11n™ Draft 2.0, IEEE802.11e™ and IEEE802.11i™

standards. If further information is required, please contact us and we will provide any
additional help needed. The WiFiHU2 series offers Soft AP support. It can turn your
Internet connected PC or Laptop into a WiFi Wireless Access Point. So any WiFi devi
such as iPhone, iPod, PDA, within range can connect to Internet by sharing your
WiFiHU2 Access Point.

Warning

Federal Communications Commission Statement Warning

Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the
user authority to operate the equipment.

“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 interfe rence, and (2) this device must accept any interference received,
including interference that may cause undesired operation.”

This device is intended only for OEM integrators under the following conditions:

1) The antenna must be installed such that 20 cm is maintained between the antenna and users. For laptop installations, the
antenna must be installed to ensure that the proper spacing is maintained in the event the users places the device in their

lap
during use (i.e. positioning of antennas must be placed in the upper portion of the LCD panel only to ensure 20 cm will be
maintained if the user places the device in their lap for use) and

2) The transmitter module may not be co-located with any other transmitter or antenna.
As long as the 2 conditions above are met, further transmitter
is still responsible for testing their end-product for any additional compliance requirements required with this module
installed (for example, digital device emissions, PC peripheral requirements, etc.).

IMPORTANT NOTE: In the event that these conditions can not be met
co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not
used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product
(including the transmitter) and obtaining a separate FCC authorization.

This transmitter module is authorized only for use in devices where the antenna may be installed such that 20 cm may be
maintained between the antenna and users (for example access points, routers, wireless ASDL modems, certain laptop
configurations, and similar equipment). The final end product must be labeled in a visible area with the following: "Contains
TX FCC ID: K7T-WIFIHU2".

The users manual for end users must include the following information in a prominent location "IMPORTANT NOTE: To
comply with FCC RF exposure compliance requirements, the antenna used for this transmitter must be installed to provide a
separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other
antenna or transmitter."

The end user should NOT be provided any instructions on how to remove or install the device.
