 PUBLIC  NOTICE  Federal  Communications  Commission 
 445  Twelfth  St.,  S.  W.  Washington,  D.  C.  20554 


 DA  01-  1557  Released:  June  29,  2001 
 Office  of  Engineering  and  Technology  Announces  Release 
 of  Revised  Supplement  C  to  OET  Bulletin  65 


 The  Commission’s  Office  of  Engineering  and  Technology  has  released  Edition  01-  01  of 
 Supplement  C  to  OET  Bulletin  65  “Evaluating  Compliance  with  FCC  Guidelines  for 
 Human  Exposure  to  Radiofrequency  Electromagnetic  Fields.”  This  revised  edition, 
 which  replaces  Edition  97-  01,  provides  additional  guidance  and  information  for 
 evaluating  compliance  of  mobile  and  portable  devices  with  FCC  limits  for 
 radiofrequency  (RF)  exposure. 


 Since  1997,  Standards  Coordinating  Committee  34,  Subcommittee  2,  of  the  Institute  of 
 Electrical  and  Electronics  Engineers,  Inc.  (IEEE  SCC-  34/  SC-  2)  has  been  developing 
 standard  recommended  procedures  for  evaluating  portable  devices  using  measurement  or 
 computational  methods.  While  this  task  has  not  yet  been  completed,  sufficient  consensus 
 now  exists  among  industry  experts  to  allow  incorporation  of  the  bulk  of  the  committee’s 
 work  into  Supplement  C.  Pending  adoption  of  a  formal  industry  standard,  this  revised 
 version  of  Supplement  C  provides  standardized  guidance  for  performing  Specific 
 Absorption  Rate  (SAR)  measurements  on  portable  devices,  as  well  as  updated  guidance 
 for  other  measurement-  based  and  computational  methods  for  evaluating  RF  exposure. 


 With  the  establishment  of  this  standardized  guidance,  the  Commission  will  now  be  able 
 to  allow  Telecommunications  Certification  Bodies  (TCBs)  to  process  certain  applications 
 for  equipment  authorization  containing  RF  exposure  evaluations.  Training  of  the  TCBs  in 
 RF  exposure  evaluation  techniques  will  be  conducted  on  August  27,  28  and  29,  2001,  in 
 Columbia,  MD,  in  cooperation  with  the  TCB  Council.  Additional  information  regarding 
 the  time  and  location  of  the  training  will  be  sent  to  TCBs  in  the  near  future.  Following 
 training  of  TCBs,  we  anticipate  allowing  TCBs  to  start  processing  such  applications  by 
 October  1,  2001.  This,  along  with  continued  processing  of  such  applications  by  the 
 FCC’s  Laboratory  Division,  will  allow  alternative  paths  to  approval  for  equipment 
 manufacturers,  ensuring  improvement  in  time-  to-  market  for  new  devices.

 Edition  01-  01  provides  for  the  interim  use  of  existing  head  phantoms  until  the  new 
 standard  head  phantom  described  in  the  new  guidelines  is  readily  commercially  available. 
 When  the  new  standard  head  phantom  becomes  commercially  available,  the  Commission 
 will  issue  a  Public  Notice  establishing  a  transition  period  of  3-  6  months  to  allow 
 interested  parties  to  acquire  this  head  phantom.  After  the  transition  period,  the  new 
 standard  head  phantom  should  be  used  for  all  SAR  testing. 


 Parties  are  encouraged  to  use  the  guidelines  contained  in  Edition  01-  01  as  soon  as 
 possible.  The  option  of  using  a  TCB  to  process  applications  for  equipment  authorization 
 will  be  available  only  for  applications  with  RF  safety  evaluations  prepared  in  accordance 
 with  the  new  guidelines. 


 New  Edition  01-  01  of  Supplement  C  supercedes  previous  Edition  97-  01.  The  document 
 may  be  downloaded  from  the  Commission’s  public  website  in  either  Microsoft  Word  or
