FCC Statement
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.
To assure continued compliance, any changes or modifications not expressly
approved by the party.
Responsible for compliance could void the user’s authority to operate this
equipment. (Example- use only shielded interface cables when connecting to
computer or peripheral devices).
This equipment 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 Radiation Exposure Statement:
The equipment complies with FCC Radiation exposure limits set forth for
uncontrolled enviroment. This equipment should be installed and operated with
minimum distance 20cm between the radiator and your body.
.

FCC Important Notes:
(1)
FCC Statement
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This
transmitter
must not be co-located or operating in conjunction with any other antenna or transmitter.
This equipment 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.
The devices must be installed and used in strict accordance with the manufacturer’s instructions as described in the user
documentation that comes with the product. Modular could be only used in mobile or fix device, and could not be used
in any portable device.
Caution!
The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications to this
equipment. Such modifications could void the user authority to operate the equipment.
FCC Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment
should be installed and operated with minimum distance 20cm between the radiator and your body.
This device and it’s antennas(s) must not be co-located or operating in conjunction with any other antenna or
transmitter except in accordance with FCC multi-transmitter product procedures.
(2)
Co-location Warning:
This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter.
(3)
OEM integration instructions:
This device is intended only for OEM integrators under the following conditions:
The transmitter module may not be co-located with any other transmitter or antenna. The module shall be only used
with the integral antenna(s) that has been originally tested and certified with this module.
As long as 3 conditions above are met, further transmitter test 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.).
(4)
Validity of using the module certification:
In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another
transmitter), then the FCC authorization for this module in combination with the host equipment is no longer
considered valid and the FCC ID of the module cannot 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.
(5)
End product labeling:
The final end product must be labeled in a visible area with the following:
“Contains Transmitter Module FCC ID: 2AC23-WT31M2311A”.
(6)
Information that must be placed in the end user manual:
The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this
RF module in the user's manual of the end product which integrates this module. The end user manual shall include all
required regulatory information/warning as show in this manual.
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.
IEEE 802.11b or 802.11g operation of this product in the USA is firmware-limited to channels 1 through 11.
The device for the band 5150-5250 MHz is only for indoor usage to reduce the potential for harmful interference to co-
channel mobile satellite systems.
