Model and Ordering Information
This versatile WiFiHU USB family of products offers various configuration options to
meet the specific system requirements a designer may need to add state of the art WiFi
USB operation. The WiFiHU is available as a module, a module with USB Jack and
antennae interface, or as a complete external device in an enclosure. The WiFiHU also
has three different antennae options.

Connecting the WiFiHU or WiFiHU-NE to Your System
The WiFiHU Modules are designed for easy connection to any standard USB Port and
wireless network. Connect one end of the USB cable into the USB connector on the
WiFiHU-NE and the other into any available USB receptacle on your computer. The
WiFiHU-NE’s “Hot Swap-able” interface allows you to plug or unplug the module even
when the computer is on. If using Windows, load the provided drivers. The WiFiHU-NE
is now ready for use.
If you plan to embed the WiFiHU into your system, the initial evaluation consists of the
WiFiHU USB Module mounted onto a USB hub PCB (WiFiHU-NE). To remove the
WiFiHU carefully remove it from the two 8 pin headers on the WiFiHU-NE USB
interface board. Save this interface board. The WiFiHU can always be reinstalled into the
WiFiHU-NE USB interface board and connected to any standard USB port to verify or
test the module functions. If you use external antenna, connect one end of Radicom
approved antenna to the on board socket.

CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
USE OR FAILURE OF SUCH PRODUCT.
38
For IC
3.2.1 Labelling Requirements for the Host device. The host device shall be properly labelled to identify the modules within the
host device. The Industry Canada certification label of a module shall be clearly visible at all times when installed in the host
device, otherwise the host device must be labelled to display the Industry Canada certification number of the module, preceded
by the words “Contains transmitter module”, or the word “Contains”, or similar wording expressing the same meaning, as
follows: Contains transmitter module IC: 2377A-WIFIHUA and 2377A-WIFIHUC2NE where 2377A-WIFIHUA and
2377A-WIFIHUC2NE are the module’s certification number. The applicant for equipment certification of the module shall
provide with each unit of the module either a label such as described above, or an explanation and instructions to the user as to
the host device labelling requirements.
For FCC
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 testing will not be required. However, the OEM
integrator 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 (for example certain laptop
configurations or co-location with another transmitter), then the FCC authorization is no longer considered
valid and the FCC ID can not be 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.
End Product Labeling
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-WIFIHU-A and K7T-WIFIHU-C-2-NE".
RF Exposure Manual Information That Must be Included
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."
Additional Information That Must be Provided to OEM Integrators
The end user should NOT be provided any instructions on how to remove or install the device.
