(b) Only those receivers that operate (tune) within the frequency range of 30-960 MHz, CB receivers and radar detectors are subject to the authorizations shown in [paragraph (a)](/on/2024-09-20/title-47/section-15.101#p-15.101(a)) of this section. Receivers operating above 960 MHz or below 30 MHz, except for radar detectors and CB receivers, are exempt from complying with the technical provisions of this part but are subject to [§ 15.5](/on/2024-09-20/title-47/section-15.5).

(c) Personal computers shall be authorized in accordance with one of the following methods:

(1) The specific combination of CPU board, power supply and enclosure is tested together and authorized under Supplier's Declaration of Conformity or a grant of certification;

(2) The personal computer is authorized under Supplier's Declaration of Conformity or a grant of certification, and the CPU board or power supply in that computer is replaced with a CPU board or power supply that has been separately authorized under Supplier's Declaration of Conformity or a grant of certification; or

(3) The CPU board and power supply used in the assembly of a personal computer have been separately authorized under Supplier's Declaration of Conformity or a grant of certification; and

(4) Personal computers assembled using either of the methods specified in [paragraphs (c)(2)](/on/2024-09-20/title-47/section-15.101#p-15.101(c)(2)) or [(c)(3)](/on/2024-09-20/title-47/section-15.101#p-15.101(c)(3)) of this section must, by themselves, also be authorized under Supplier's Declaration of Conformity if they are marketed. However, additional testing is not required for this Supplier's Declaration of Conformity, provided the procedures in [§ 15.102(b)](/on/2024-09-20/title-47/section-15.102#p-15.102(b)) are followed.

(d) Peripheral devices, as defined in [§ 15.3(r)](/on/2024-09-20/title-47/section-15.3#p-15.3(r)), shall be authorized under Supplier's Declaration of Conformity, or a grant of certification, as appropriate, prior to marketing. Regardless of the provisions of [paragraphs (a)](/on/2024-09-20/title-47/section-15.101#p-15.101(a)) or [(c)](/on/2024-09-20/title-47/section-15.101#p-15.101(c)) of this section, if a CPU board, power supply, or peripheral device will always be marketed with a specific personal computer, it is not necessary to obtain a separate authorization for that product provided the specific combination of personal computer, peripheral device, CPU board and power supply has been authorized under Supplier's Declaration of Conformity or a grant of certification as a personal computer.

(1) No authorization is required for a peripheral device or a subassembly that is sold to an equipment manufacturer for further fabrication; that manufacturer is responsible for obtaining the necessary authorization prior to further marketing to a vendor or to a user.

(2) Power supplies and CPU boards that have not been separately authorized and are designed for use with personal computers may be imported and marketed only to a personal computer equipment manufacturer that has indicated, in writing, to the seller or importer that they will obtain Supplier's Declaration of Conformity or a grant of certification for the personal computer employing these components.

(e) Subassemblies to digital devices are not subject to the technical standards in this part unless they are marketed as part of a system in which case the resulting system must comply with the applicable regulations. Subassemblies include:

(1) Devices that are enclosed solely within the enclosure housing the digital device, except for: Power supplies used in personal computers; devices included under the definition of a peripheral device in [§ 15.3(r)](/on/2024-09-20/title-47/section-15.3#p-15.3(r)); and personal computer CPU boards, as defined in [§ 15.3(bb)](/on/2024-09-20/title-47/section-15.3#p-15.3(bb));

(2) CPU boards, as defined in [§ 15.3(bb)](/on/2024-09-20/title-47/section-15.3#p-15.3(bb)), other than those used in personal computers, that are marketed without an enclosure or power supply; and

(3) Switching power supplies that are separately marketed and are solely for use internal to a device other than a personal computer.
