11. FCC Warning Statement
FEDERAL COMMUNICATIONS COMMISSION REGULATIONS
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 or more 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.
CAUTION:
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's 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 interference and
(2) This device must accept any interference received, including interference that may
cause undesired operation.
FCC RF Radiation Exposure Statement
This equipment complies with FCC/IC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20 cm
between the radiator & your body.
Important Note
In the event that these conditions can not be example certain laptop configurations or
collocation with another transmitter, then the FCC authorization is no longer considered valid the
FCC ID can not be used on the final product. In these circumstances, OEM integrator will be
responsible for re-evaluating the end product (including the transmitter) and obtaining a separate
FCC authorization.
End Product Labeling
When the module is installed in the host device, the FCC ID label must be visible through a window
on the final device or it must be visible when an access panel, door or cover is easily re-moved. If not,
a second label must be placed on the outside of the final device that contains the following text
“Contains FCC ID 2ALWN-W708”
The FCC ID can be used only when all FCC compliance requirements are met.

The module is limited to OEM installation ONLY
The module is limited to installation in mobile or fixed applications, according to Part 2.1091(b)
The separate approval is required for all other operating configurations, including portable
configurations with respect to Part 2.1093 and different antenna configurations
The end user must not have manual instructions to remove or install device. The
user 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 operating in conjunction with
any other antenna or transmitter.” as a result of e-mail transmission.”
