Co-location warning:
This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
Limited Channels fixed for use in the US:
IEEE 802.11b or 802.11g or 802.11n(HT20) operation of this
product in the U.S. is firmware-limited to Channel 1 through 11.
IEEE 802.11n(HT40) operation of this product in the U.S. is
firmware-limited to Channel 3 through 9.
OEM integration instructions:
This device is intended only for OEM integrators under the
following conditions:
The antenna must be installed such that 20 cm is maintained
between the antenna and users, and the transmitter module may
not be co-located with any other transmitter or antenna. The
module shall be only used with the external antenna(s) that has
been originally tested and certified with this module.
6
Alinket Technology Co. (Shanghai) Ltd. Module Product User Manual
AN-ALX8XX-WIP2.2
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.).
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.
End product labeling:
This transmitter module is authorized only for use in device
where the antenna may be installed such that 20 cm may be
7

maintained between the antenna and users. The final end product
must be labeled in a visible area with the following: “Contains
Transmitter Module FCC ID: 2AELJ-ALX8XX”.
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.
