22 

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. 

 

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. 

 

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
