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 on and off, the user is encouraged to try to correct the interference by one or more of the following measures: -Reorient or relocate the receiving antennae -Increase the separation between the equipment and the 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. FCC RF Exposure Statement The highest SAR value reported under this standard during product certification for use next to the head with the minimum separation distance of 10mm is 0.533W/Kg. This transmitter must not be collocated or operating in conjunction with any other antenna or transmitter. This product is compliance to FCC RF Exposure requirements and refers to FCC website https://apps.fcc.gov/oetcf/eas/reports/GenericSearch.cfm search for FCC ID: S7A-SP83, IC:8154A-SP83. When equipped, the distance between antenna and one’s head surface is more than 10mm. FCC Caution Any changes or modifications to the equipment not expressly approved by the party responsible for compliance could void user’s authority to operate the equipment. Certification et homologation de sécurité Déclaration de conformité FCC Cet appareil est en conformité avec la partie 15 des règles de la FCC. Son fonctionnement est soumis aux deux conditions suivantes : (1) Cet appareil ne doiᄂᄃt pas créer d’interférences préjudiciables et (2) Cet appareil doit accepter toutes les interférences reçues, y compris celles qui pourraient entraver son bon fonctionnement. Cet équipement a été testé et jugé conforme aux limites pour un appareil numérique de classe B, conformément à la partie 15 des règles de la FCC. Ces limites sont conçues pour fournir une protection raisonnable contre les interférences nuisibles dans une installation résidentielle. Cet équipement génère et utilise de l’énergie radio fréquence et, s’il n’est pas installé et utilisé conformément. aux instructions, il peut occasionner des interférences nuisibles au niveau des communications radios. Cependant, il n’existe aucune garantie que ces interférences ne se produiront pas dans une installation particulière. Si cet équipement génère des interférences nuisibles à la réception de la radio ou de la télévision (ce qu’il est possible de déterminer en mettant l’équipement hors tension, puis sous tension), l’utilisateur est invité à suivre une ou plusieurs des mesures suivantes pour corriger le problème des interférences en prenant l’une des mesures suivantes : -Modifier l’emplacement ou l’orientation de l’antenne de réception. -É loigner l’appareil du récepteur. -Brancher l’appareil sur une prise située sur un circuit différent de celui du récepteur. -Consulter le revendeur ou un technicien expérimenté pour obtenir de l’aide. É noncé FCC sur l’exposition aux radiations RF La valeur DAS la plus élevée rapportée dans le cadre de cette norme lors de la certification du produit pour une utilisation à côté de la tête avec une distance de séparation minimale de 10mm est de 0.533 W/Kg. Cet émetteur ne doit pas être colocalisé ni fonctionner avec une autre antenne ou un autre émetteur.
