Preliminary 1 Revision 0.1 (07/2021) EV73R53A Regulatory Compliance Information Revision 0.1 Jul’ 2021 Preliminary 2 Revision 0.1 (07/2021) This document contains the Regulatory Compliance information which will be part of the EV73R53A (ATA5291-XPRO) datasheet and related documents shared with customers. Preliminary 3 Revision 0.1 (07/2021) 1.0 Usage Instructions This equipment (EV73R53A/ATA5291-XPRO) is an evaluation board of the ATAK51005-V1 kit. It is not directly marketed or sold to the general public through retail; it is only sold through authorized distributors or through Microchip. Using this equipment requires a significant engineering expertise towards understanding of the tools and relevant technology, which can be expected only from a person who is professionally trained in the technology. The user must comply with all the instructions provided by the Grantee, which indicate installation and/or operating conditions necessary for compliance. 2.0 Antenna Considerations The following table provides details about the approved antenna. Part Number Manufacturer Antenna type ATAB-LFTX-V4.0 Microchip Ferrite rod 3.0 Regulatory Approval This equipment has received regulatory approval for the following countries:  United States/FCC ID: 2ADHK73R53  Canada/ISED: o IC ID: 20266-73R53 o HVIN: EV73R53A  European Union/CE 3.1.0 United States This equipment has been approved for use in the United States under Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Subpart C “Intentional Radiators”. 3.1.1 Labeling and User Information The FCC ID label has been permanently affixed to equipment on the top silkscreen layer of the board and is visible, as well as, legible to the user. Due to the size of the equipment, the following compliance statements are included in the user manual: 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. WARNING: Any changes or modifications to this equipment not expressively approved by the Grantee could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the Federal Communications Commission (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. Preliminary 4 Revision 0.1 (07/2021)  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. Additional information on labeling and user information requirements for Part 15 devices can be found in KDB Publication 784748, which is available at the FCC Office of Engineering and Technology (OET) Laboratory Division Knowledge Database (KDB) https://apps.fcc.gov/oetcf/kdb/index.cfm. 3.1.2 Approved Antenna Types To maintain compliance in the United States, only the antenna type that has been tested shall be used.
