2AJYB-S1955 FCC IC Instruction For Use_20200110.docx January 10, 2020 Page 6 of 11 StreamUnlimited Engineering GmbH Gutheil-Schoder-G. 10, 1100 Vienna, Austria T +43-1-667 2002, F +43-1-667 2002 4401 3.1 Product labelling requirements Product label must contain following text: “contains FCC ID: 2AJYB-S1955” “contains IC: 20504-S1955” See below example for reference 3.2 Instruction for use requirements Instructions for use must contain warnings and customer information, see next two pages for detailed text Declaration of Conformity 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 product does not contain any user serviceable components. Any unauthorized product changes or modifications will invalidate warranty and all applicable regulatory certifications and approvals, including authority to operate this device. Warning 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. Caution: Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 2AJYB-S1955 FCC IC Instruction For Use_20200110.docx January 10, 2020 Page 7 of 11 StreamUnlimited Engineering GmbH Gutheil-Schoder-G. 10, 1100 Vienna, Austria T +43-1-667 2002, F +43-1-667 2002 4401 Operations in the 5.15 – 5.25GHz band are restricted to indoor usage only. RF Exposure Requirements To comply with FCC requirements, a minimum separation distance of 20cm (8 inches) is required between the equipment and the body of the user or nearby persons. Canada: This Class B digital apparatus complies with Canadian ICES-003 and RSS-247. 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. The installer of this radio equipment must ensure that the product is located such that it does not emit RF field in excess of Health Canada limits for the general population: consult Safety Code 6, obtainable from Health Canada ́s We site www.hc-sc.gc.ca/rpb. As mentioned before, the installer cannot control the antenna orientation. However, they could place the complete product in a way that causes the problem mentioned above. The device for operation in the band 5150-5250 MHz is only for indoor use to reduce the potential for harmful interference to co-channel mobile satellite systems. Be advices that high-power radars are allocated as primary users (i.e. priority users) of the bands 5250-5350MHz and 5650-5850MHz and that these radars could cause interference and/or damage to LE-LAN devices. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Cet appareil numérique de classe B est conforme aux normes NMB-003 et CNR-247 en vigueur au Canada. Son fonctionnnement est soumis aux deux conditions suivantes : (1) Cet appareil ne doit pas créer d'interférences nuisibles. (2) Cet appareil doit tolérer toutes les interférences reçues, y compris les interférences pouvant entraîner un fonctionnement indésirable. L'installateur du présent matériel radio doit veiller à ce que le produit soit placé ou orienté de manière à n'émettre aucun champ radioélectrique supérieur aux limites fixées pour le grand public par le ministère fédéral Santé Canada ; consultez le Code de sécurité 6 sur le site Web de Santé Canada à l'adresse : www.hc-sc.gc.ca/rpb. Comme indiqué auparavant, l'installateur ne peut pas contrôler l'orientation de l'antenne. Il peut néanmoins placer le produit tout entier de manière à provoquer le problème décrit ci-dessus. Les dispositifs fonctionnant dans la bande 5150-5250 MHz sont réservés uniquement pour une utilisation à l'intérieur afin de réduire les risques de brouillage préjudiciable aux systèmes de satellites mobiles utilisant les mêmes canaux. Les utilisateurs de radars de haute puissance sont désignés utilisateurs principaux (c.-à-d., qu'ils ont la priorité) pour les bandes 5250-5350 MHz et 5650-5850 MHz et que ces radars pourraient causer du brouillage et/ou des dommages aux dispositifs LAN-EL.
