This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada s licence-exempt RSS(s). Operation is subject to the following two conditions:

(1) This device may not cause interference.

(2)This device must accept any interference, including interference that may cause undesired operation of the device. L'metteur/rcepteur exempt de licence contenu dans le prsent appareil est conforme aux CNR d'Innovation, Sciences et Dveloppement conomique Canada applicables aux appareils radio exempts de licence. L'exploitation est autorise aux deux conditions suivantes :

(1)L'appareil ne doit pas produire de brouillage;

(2)L'appareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible d'en compromettre le fonctionnement. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.Cet metteur ne doit pas tre Co-plac ou ne fonctionnant en mme temps qu'aucune autre antenne oumetteur. Please notice that if the ISED certification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: Contains IC:

28042-SKGBLEJL01 any similar wording that expresses the same meaning may be used. Veuillez noter que si le numro de certification ISDE nest pas visible lorsque le module est install l intrieur dun autre dispositif, alors lextrieur du dispositif dans lequel le module est install doit galement afficher une tiquette se rfrant au module ferm. Cette tiquette extrieure peut utiliser des libells tels que: contient IC: 28042-SKGBLEJL01 toute formulation similaire qui exprime la mme signification peut tre utilise.
