# §95.335. Operation of non-certified transmitters prohibited.


Except as provided in [paragraph (a)](#a) of this section, no person shall operate a transmitter in any Personal Radio Service unless it is a certified transmitter; that is, a transmitter of a type which has obtained a grant of equipment certification for that service, pursuant to [part 2](/cfr/47/part2.md), [subpart J](/cfr/47/subpartJ.md) of this chapter. Use of a transmitter that is not FCC-certified voids the user's authority to operate that station. See sections 302(a), (b), and (e) of the Communications Act (47 U.S.C. [302(a)](/usc/47/302.md?p=a), [(b)](/usc/47/302.md?p=b), and [(e)](/usc/47/302.md?p=e)).

- (a) **Exceptions.** Under certain exceptions, non-certified Personal Radio Service transmitters, or transmitters certified for use in the land mobile radio services may be operated. Any such exceptions applicable to stations in a Personal Radio Service are set forth in the subpart governing that specific service. See e.g., §§ [95.735](/cfr/47/95.735.md) and [95.1735](/cfr/47/95.1735.md).
- (b) **Revoked or withdrawn certification.** In the event that the FCC revokes or withdraws a grant of equipment certification for a type of Personal Radio Service transmitter, existing transmitters already in service may continue to be operated unless and until the FCC determines otherwise and gives Public Notice of that decision.
- (c) **Grantee permissible modifications.** Only the grantee of the equipment certification may modify the design of a certified Personal Radio Service transmitter type, and then only pursuant to and in full compliance with the requirements and procedures for permissible changes and modifications in [part 2](/cfr/47/part2.md) of this chapter. See §§ [2.932](/cfr/47/2.932.md) and [2.1043](/cfr/47/2.1043.md) of this chapter.
