In order to carry out its responsibilities under the Communications Act and the various treaties and international regulations, and in order to promote efficient use of the radio spectrum, the Commission has developed technical standards for radio frequency equipment and parts or components thereof. The technical standards applicable to individual types of equipment are found in that part of the rules governing the service wherein the equipment is to be operated. In addition to the technical standards provided, the rules governing the service may require that such equipment be verified by the manufacturer or importer, be authorized under a Declaration of Conformity, or receive a grant of Certification from a Telecommunication Certification Body. This document explains the Declaration of Conformity authorization process.
FCC Title 47, part 2 defines the method as follows. A Declaration of Conformity is a procedure where the responsible party makes measurements or takes other necessary steps to ensure that the equipment complies with the appropriate technical standards. Submittal of a sample unit or representative data to the Commission demonstrating compliance is not required unless specifically requested.
FCC Title 47, part 15 lists the following device types as falling within the DoC authorization procedure. Optionally most of these types can also be authorized under the certification procedures.
Super regenerative receiver
All other receivers subject to part 15
TV interface device
Cable system terminal device
Class B personal computers and peripherals
CPU boards and internal power supplies used with Class B personal computers
Class B personal computers assembled using authorized CPU boards or power supplies
The test and technical standards can be found in FCC Title 47, part 15.31 which lists ANSI C63.4 as the applicable measurement methods for unintentional radiators. Powerline conducted and Radiated field strength EM emissions measurements are required and the applicable Class B limits can be found in FCC Part 15.107 and 15.109 respectively.
Equipment authorized under the DoC or certification procedure shall be tested at a laboratory that is accredited to ISO/IEC 17025 by a recognized accreditation organization and listed as approved with the FCC.
A technical test report, along with additional documentation will be kept on file and made available to the FCC on request. The following items are then prepared by the responsible party;
Prepare a Declaration of Conformity (DoC), and include it with the product literature.
Prepare a label for the unit.
Include mandatory user’s manual information regarding the interference potential of the device.
(Include in user’s manual or separate sheet)

COMPLIANCE TEST REPORT DATE:
RESPONSIBLE PARTY (IN USA): Manufacturer, assembler, importer, or retailer (must be located in United States!)
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules as documented in the above referenced test report. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
This equipment referenced in this declaration is identical to the unit tested and found acceptable with the standards. The technical records maintained by the responsible party continue to reflect the equipment being produced under this Declaration of Conformity within the variation that can be expected due to quantity production and testing on a statistical basis.
Each product shall be labeled, in a conspicuous location, with the unique identification of the product as defined in Title 47 §2.1074
The label shall not be a stick-on, paper label. The label on these products shall be permanently affixed to the product and shall be readily visible to the purchaser at the time of purchase, as described in §2.925(d). “Permanently affixed” means that the label is etched, engraved, stamped, silkscreened, indelibly printed, or otherwise permanently marked on a permanently attached part of the equipment or on a nameplate of metal, plastic, or other material fastened to the equipment by welding, riveting, or a permanent adhesive. The label must be designed to last the expected lifetime of the equipment in the environment in which the equipment may be operated and must not be readily detachable.

For a product assembled from tested components but not tested as a system;
(Located in manual or operating instruction)
This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
The user is cautioned that changes and modifications made to the equipment without the approval of manufacturer could void the user’s authority to operate this equipment.
<<< If shielded cables were used for testing include >>>
<<< In order to maintain compliance with FCC regulations, shielded cables must be used with this equipment. Operation with non-approved equipment or unshielded cables is likely to result in interference to radio and TV reception. >>>>
The Declaration of Conformity signifies that the responsible party, as defined in FCC Title 47 part 2.909, has determined that the equipment has been shown to comply with the applicable technical standards if no unauthorized change is made in the equipment and if the equipment is properly maintained and operated. Compliance with these standards shall not be construed to be a finding by the responsible party with respect to matters not encompassed by the Commission’s rules.
No person shall, in any advertising matter, brochure, etc., use or make reference to a Declaration of Conformity in a deceptive or misleading manner or convey the impression that such a Declaration of Conformity reflects more than a determination by the responsible party that the device or product has been shown to be capable of complying with the applicable technical standards of the Commission’s rules.
The responsible party for a Declaration of Conformity must be located within the United States. The responsible party can be the Manufacturer, assemble or importer. In addition to providing the DoC, you are also required to include the FCC statement to the user in the userís manual. The compliance Test report must be in English language and must be available to the FCC within 14 days of delivery of the request.
The compliance information statement shall be included in the user’s manual or as a separate sheet. In cases where the manual is provided only in a form other than paper, such as on a computer disk or over the Internet, the information required may be included in the manual in that alternative form, provided the user can reasonably be expected to have the capability to access information in that form.
