FCC Warning 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. 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. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. FCC WARNING This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End user must follow the specific operating instructions for satisfying RF exposure compliance. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The mobile device is designed to meet the requirements for exposure to radio waves established by the Federal Communications Commission (USA). These requirements set a SAR limit of 1.6 W/kg averaged over one gram of tissue. The highest SAR value reported under this standard during product certification for use when properly worn on the body is 0.911 W/kg. For body operation, this device has been tested and meets FCC RF exposure guidelines when used with any accessory that contains no metal and that positions a minimum of 0mm from the body. Use of other accessories may not ensure compliance with FCC RF exposure guidelines. ISED Warning This device complies with Innovation, Science and Economic Development Canada’s license- exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause harmful interference, (2) this device must accept any interference, including interference that may cause undesired operation of the device. Cet appareil est conforme aux normes RSS exemptées de licence d’innovation, sciences et développement économique Canada. Le fonctionnement est soumis aux deux conditions suivantes: (1) ce dispositif ne peut pas causer d’interférence nuisible, (2) ce dispositif doit accepter toute interférence, y compris l’interférence qui peut causer un fonctionnement indésirable du dispositif. IC WARNING This equipment complies with ISED radiation exposure limits set forth for an uncontrolled environment. End user must follow the specific operating instructions for satisfying RF exposure compliance. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The mobile device is designed to meet the requirements for exposure to radio waves established by the Innovation, Science and Economic Development Canada (Canada).

Use of other accessories may not ensure compliance with ISED RF exposure guidelines. Cet équipement est conforme aux limites d'exposition aux rayonnements ISED établies pour un environnement non contrôlé. L'utilisateur final doit suivre les instructions d'utilisation spécifiques pour satisfaire la conformité d'exposition RF. Cet émetteur ne doit pas être co- localisé ou fonctionner en conjonction avec une autre antenne ou un autre émetteur. L'appareil mobile est conçu pour répondre aux exigences d'exposition aux ondes radio établies par Innovation, Sciences et Développement économique Canada (Canada). Ces exigences fixent une limite DAS de 1,6 W/kg en moyenne sur un gramme de tissu. La valeur SAR la plus élevée signalée dans le cadre de cette norme lors de la certifi cation du produit à utiliser lorsqu'il est correctement porté sur le corps est de 0,911W/kg. Pour le fonctionnement du corps, cet appareil a été testé et répond aux directives d'exposition RF ISED lorsqu'il est utilisé avec tout accessoire qui ne contient pas de métal et qui se positionne à au moins 0 mm du corps. L'utilisation d'autres accessoires peut ne pas garantir la conformité aux directives d'exposition RF ISED.
