Federal Communication Commission Interference Statement 

 

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. 

 

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  transmitter  must  not  be  co-located  or  operating  in  conjunction  with  any  other  antenna  or 

transmitter. 

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 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. 

 

As long as 2 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
