 external switching power supplies.
Access Broadband over Power Line (Access  Certification.
All other devices.......................  Verification.
    (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) of this section. However, 
receivers indicated as being subject to Declaration of Conformity that 
are contained within a transceiver, the transmitter portion of which is 
subject to certification, shall
[[Page 766]]
be authorized under the verification procedure. 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 Sec. 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 a Declaration of 
Conformity or a grant of certification;
    (2) The personal computer is authorized under a 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 a 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 a Declaration of 
Conformity or a grant of certification; and
    (4) Personal computers assembled using either of the methods 
specified in paragraphs (c)(2) or (c)(3) of this section must, by 
themselves, also be authorized under a Declaration of Conformity if they 
are marketed. However, additional testing is not required for this 
Declaration of Conformity, provided the procedures in Sec. 15.102(b) 
are followed.
    (d) Peripheral devices, as defined in Sec. 15.3(r), shall be 
authorized under a Declaration of Conformity, or a grant of 
certification, or verified, as appropriate, prior to marketing. 
Regardless of the provisions of paragraphs (a) or (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 a 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 
    (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 a 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 Sec. 15.3(r); and personal computer CPU boards, as defined in Sec. 
    (2) CPU boards, as defined in Sec. 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.
    (f) The procedures for obtaining a grant of certification or 
notification and for verification and a Declaration of Conformity are 
contained in subpart J of part 2 of this chapter.
