11. RFx information 

The  RF  field  strength  of  the  wireless  module  or  modules  that  may  be 

embedded in your TCU is well all international RF exposure limits as known 
at  this  time.  Because  the  wireless  modules(which  may  be  embedded  into 

your  TCU)  emit  less  energy  than  is  allowed  in  radio  frequency  safety 

standards  and  recommendations,  manufacturer  believes  these  modules   

are  safe  for use.  Regardless  of  the  power  levels,  care  should  be  taken  to 

minimize human contact during normal operation. 

This  module  should  be  used  more  than  20cm(8  inches)  from  the  body 

when wireless devices are on and transmitting. 

This  transmitter  must  not  be  collocated  or  operate  in  conjunction  with 

any other antenna or transmitter. 

Operation is subject to the following two conditions: (1) this module may 

not cause interference , (2) this module must accept any interference that 

may cause undesired operation. 

 

11.1

 

Information for integrator 

The 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 

manual of the end product. 

The user manual which is provided by integrators for end users must 
include the following information in a prominent location. 

To comply with FCC RF exposure compliance requirements, 

      the antenna(W8E-MWC-20 Tri-band Dipole Antenna)   

  used  for  this  transmitter  must  be  installed  to  provide  a  separation 

distance  of  at  least  20cm  from  all  persons  and  must  not  be  co-
located  or  operating  in  conjunction  with  any  other  antenna  or 

transmitter. 
Label for end product must include Contains FCC ID : YZP-D660V or 

A RF transmitter inside, FCC ID : YZP-D660V
