Cet appareil numrique de classe b est conforme la norme nmb-003 du canada. This device is intended only for OEM integrators under the following condition: The transmitter module may not be co-located with any other transmitter or antenna. As long as the condition above is met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed. Cet appareil est conu uniquement pour les intgrateurs OEM dans les conditions suivantes:
Le module metteur peut ne pas tre complant avec un autre metteur ou antenne. Tant que les 1 condition ci-dessus sont remplies, des essais supplmentaires sur l'metteur ne seront pas ncessaires. Toutefois, l'intgrateur OEM est toujours responsable des essais sur son produit final pour toutes exigences de conformit supplmentaires requis pour ce module install. Important Note:
In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the Canada authorization is no longer considered valid and the ISED cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate Canada authorization. Any company of the host device which install this modular with limit modular approval should perform the test of radiated emission and spurious emission according to RSS-247 and RSSGen requirement, only if the test result comply with RSS-247 and RSS-Gen requirement, then the host can be sold legally. Note Importante:
Dans le cas o ces conditions ne peuvent tre satisfaites (par exemple pour certaines configurations d'ordinateur portable ou de certaines co-localisation avec un autre metteur), l'autorisation du Canada n'est plus considr comme valide et l' ISED ne peut pas tre utilis sur le produit final.
