Thanks a lot for quick responds. I was a bit surprised when I heard this "rumour" today and since the person was very self-confident ( and stubborn..), I had to check it out with you. Amund
Fra: Kathy Maclean [mailto:[email protected]] Sendt: 29. september 2003 20:01 Til: [email protected]; [email protected] Emne: RE: FCC - TCB Dear Amund - The TCB's have to follow the rules of the FCC. That means that if the device in question requires full re-testing by the FCC, then indeed, this will be required by the TCB also. If the device requires partial testing, e.g. for a Class II Permissive Change, it will do so regardless of whether it was approved by a TCB or the FCC. Note, that if you make changes, you are under no obligation to use the same TCB unless you want to. HOWEVER, TCB's are NOT authorized to interpret or change FCC rules, and they are excluded from approving certain classes of devices ("exclusion list"). This means that if you have a "special case" which may require particular application of rules, or if you have a device which falls under the exclusion list, you must use FCC for approval (whether it is a new application or a change).

I have been told that if you modify it later on, the will TCB require full re-testing (all tests). Is that true ? Amund Oslo / Norway
