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. 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 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. This device complies with Innovation, Science, and Economic Development Canad 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. Le présent appareil est conforme aux CNR d' Innovation, Sciences et Développement économique Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes: (1) l'appareil nedoit 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. 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. L'appareil destiné à fonctionner dans la bande 5150–5250 MHz est uniquement destiné à une utilisation en intérieur afin de réduire le risque d'interférence nuisible aux systèmes mobiles par satellite utilisant le même canal. The device has been tested and comply with FCC/ISED SAR limits. Users can obtain FCC/ISED information on RF exposure and compliance, this equipment should be installed and operated with minimum distance 5mm between the radiator& your body. Cet appareil a été testé et est conforme aux limites SAR de la FCC/ISED. Les utilisateurs peuvent consulter les renseignements de la FCC/ISED concernant l'exposition aux radiofréquences et la conformité. Cet équipement doit être installé et utilisé à une distance minimale de 5 mm entre l'émetteur et le corps. Produttore Shenzhen Sihaijialan Electronic Technology Co., Ltd.

The measured SAR does not deviate more than 10% from the target on the calibration certificate. 2. The return-loss does not deviate more than 20% from the previous measurement and meets the required 20 dB minimum return-loss requirement. 3. The measurement of real or imaginary parts of impedance does not deviate more than 5Ω from the previous measurement.
