Federal Communication Commission Interference 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 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. 
 
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. 
 
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. 
IMPORTANT NOTE: 
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 & your body 
 
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 
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, and 
2)•The transmitter module may not be co-located with any other transmitter or antenna, 
3)•For all products market in US, OEM has to limit the operation channels in CH1 to CH11 for 2.4G band by supplied firmware  
programming tool. OEM shall not supply any tool or info to the end-user regarding to Regulatory Domain change. 
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 
 
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 device where the antenna may be installed such that 20 cm may be  
maintained between the antenna and users. The final end product must be labeled in a visible area with the following:  
“Contains FCC ID: E2K-DWBT2”. 
Manual Information To the End User 
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.
