1. General Description 
This document is to specify the product requirements for 802.11a/b/g/n/ac USB Module. This Card is based 
on Realtek RTL8812AU chipset that complied with IEEE 802.11b/g/n/ac Draft 3.0 compatible WLAN ,and it 
is also backward complied with IEEE 802.11a standard from 5.15~5.825GHz wideband and IEEE 
802.11b/g standard from 2.4~2.5GHz. It can be used to provide up to 54Mbps for IEEE 802.11a and IEEE 
802.11g,11Mbps for IEEE 802.11b and 150Mbps for IEEE 802.11n and 433.3Mbps for IEEE 802.11ac    to 
connect your wireless LAN. 
With seamless roaming, fully interoperability and advanced security with WEP standard,    802.11 
a/b/g/n/ac USB Module offers absolute interoperability with different vendors 802.11a/b/g/n/ac.Access 
Points through the wireless LAN.

Appendix 2 : Statement   
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: LNQSBRT8812AU”. 
(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.
