UM2535 Federal Communications Commission (FCC) and Industry Canada (IC) Compliance Statements Appendix C Federal Communications Commission (FCC) and Industry Canada (IC) Compliance Statements C.1 FCC Compliance Statement Part 15.19 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. Part 15.21 Any changes or modifications to this equipment not expressly approved by STMicroelectronics may cause harmful interference and void the user's authority to operate this equipment. Part 15.105 This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. FCC ID FCC ID: YCP-MB1263-000. C.2 IC Compliance Statement This device complies with FCC and Industry Canada RF radiation exposure limits set forth for general population for mobile application (uncontrolled exposure). This device must not be collocated or operating in conjunction with any other antenna or transmitter. Compliance Statement Notice: This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Industry Canada ICES-003 Compliance Label: CAN ICES-3 (A)/NMB-3(A). Déclaration de conformité Avis: Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.

UM2535 Safety instructions Appendix E Safety instructions E.1 Safety instructions • The STM32MP157x-EV1 Evaluation board is designed to be powered from the 5 V DC power supply unit provided in the package. The power supply acting as a disconnection device must remain easily accessible in case of issue. • Marking observed on the power supply unit: Marking for Class II product. Such product does not require a safety connection to electrical earth. For indoor use only. This marking indicates that the product operates with an alternating current (AC) source (mains). It is completed by afferent values (voltage, frequency and max current). This marking indicates that the terminal is suitable for direct current (DC) only. It is completed by afferent values (voltage and max current). The associated symbol means that WEEE and waste batteries must not be thrown away but collected separately and recycled. • Do not expose it to heat from any source. • Do not expose it to water, moisture or place on a conductive surface while in operation. UM2535 - Rev 2 page 51/59

UM2535 Sicherheitshinweise E.2 Sicherheitshinweise • Das Evaluierungsboard STM32MP157x-EV1 ist ausgelegt für den Betrieb mit dem im Lieferumfang enthaltenen 5V DC Netzteil. Das Netzteil muss frei zugänglich sein damit es jederzeit im Fall einer Gefahr oder einer Störung vom Netz getrennt werden kann. • Kennzeichnung am Netzteil beachtet: Kennzeichnung für Produkte der Klasse II. Für ein solches Produkt ist keine Erdung erforderlich. Nur für den Innengebrauch. Diese Markierung zeigt an, dass das Produkt nur mit einer Wechselspannung (Netz) betrieben werden darf. Diese Markierung zeigt an, dass das Terminal nur für Gleichstrom (DC) geeignet ist. Das Netzteil versorgt das Terminal mit der angepassten Spannung. Das zugehörige Symbol bedeutet, dass Elektro- und Elektronik-Altgeräte nicht weggeworfen, sondern getrennt gesammelt und recycelt werden müssen. • Setzen Sie es keiner Wärmequelle aus. • Setzen Sie es während des Betriebs weder Wasser noch Feuchtigkeit aus und legen Sie es nicht auf eine leitfähige Oberfläche.
