Caution: If any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. Operation is subject to the following two conditions: (1) This device may not cause harmful interfe- rence, and (2) This device must accept any interference received, including interference that may cause undesired operation. The grantee is not responsible for any changes or modifications not expressly approved by the party responsible for compliance. Such modifica- tions could void the user’s authority to operate the equipment. The RF Exposure Compliance distance is 5 mm. 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 FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential instal- lation. 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 communica- tions. However, there is no guarantee that interfe- rence 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. 2. ISED Statement ENG | This device complies with Innovation, Science and Economic Development 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. CAN ICES-3(B)/NMB-3(B) The device meets the exemption from the routine evaluation limits in section 2.5 of RSS 102 and compliance with RSS-102 RF exposure, users can obtain Canadian information on RF exposure and compliance. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This equipment should be installed and operated with a minimum distance of 5 millimeters between the radiator and your body. FR | Le présent appareil est conforme aux CNR Innovation, Sciences et Développement économique Canada applicables aux appareils radio exempts de licence. L‘exploitation est autorisée aux deux condi- tions suivantes: (1) il ne doit pas produire de brouillage et (2) l’ utilisateur du dispositif doit étre prêt à accepter tout brouillage radioélectrique reçu, même si ce brouillage est susceptible de compromettre le fomctionnement du dispositif. CAN ICES-3(B)/NMB-3(B) Le dispositif rencontre l‘exemption des limites courantes d‘évaluation dans la section 2.5 de RSS 102 et la conformité à l‘exposition de RSS-102 rf, utilisateurs peut obtenir l‘information canadienne sur l‘exposition et la conformité de rf. Cet émetteur ne doit pas être Co-placé ou ne fonc- tionnant en même temps qu‘aucune autre antenne ou émetteur. Cet équipement devrait être installé et actionné avec une distance minimum de 20 millimètres entre le radiateur et votre corps.

(Manufacturer specified the separation distance is: 5mm) Step a) >> Numeric threshold (2402MHz), mW / 5mm * √2.402GHz ≤ 3.0 Numeric threshold (2402MHz) ≤ 9.678mW >> Numeric threshold (2440MHz), mW / 5mm * √2.440GHz ≤ 3.0 Numeric threshold (2440MHz) ≤ 9.602mW >> Numeric threshold (2480MHz), mW / 5mm * √2.480GHz ≤ 3.0 Numeric threshold (2480MHz) ≤ 9.525mW >> The power of EUT measured (2402MHz) is: -0.85dBm = 0.822mW The power of EUT measured (2440MHz) is: -0.48dBm = 0.895mW The power of EUT measured (2480MHz) is: -0.56dBm = 0.879mW Which is smaller than the Numeric threshold. Therefore, the device is exempt from stand-alone SAR test requirements. 9AppendixA-General Product Information
