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 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.  FCC Caution: Any changes  or modifications  not  expressly approved  by the  party responsible for compliance could void the user's authority to operate this equipment.  This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
                                             USER MANUAL                                              WN7911C-LF  16 Radiation Exposure Statement: This  equipment  complies  with  FCC  radiation  exposure  limits  set  forth  for  an  uncontrolled environment.  This  equipment  should  be  installed  and  operated  with  minimum  distance  20cm between the radiator & your body.  This device is intended only for OEM integrators under the following conditions:  1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and   2) The transmitter module may not be co-located with any other transmitter or antenna.  As long as 2 conditions above are 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  IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not 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 FCC authorization.  End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users. The final end product must be labeled in a visible area with the following: “Contains FCC ID: QDX31500”. The grantee's FCC ID can be used only when all FCC compliance requirements are met.  Manual Information To the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual.

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. Ce dispositif est conforme à la norme CNR-210 d'Industrie Canada applicable aux appareils radio exempts de licence. Son fonctionnement est sujet aux deux conditions suivantes: (1) le dispositif ne doit pas produire de brouillage préjudiciable, et (2) ce dispositif doit accepter tout brouillage reçu, y compris un brouillage susceptible de provoquer un fonctionnement indésirable.   Radiation Exposure Statement: This  equipment  complies  with  IC  radiation  exposure  limits  set  forth  for  an  uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body.  Déclaration d'exposition aux radiations: Cet équipement est conforme aux limites d'exposition aux rayonnements IC établies pour un environnement non contrôlé. Cet équipement doit être installé et utilisé avec un minimum de 20 cm de distance entre la source de rayonnement et votre corps.

As long as 2 conditions above are 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 conçu uniquement pour les intégrateurs OEM dans les conditions suivantes: (Pour utilisation de dispositif module) 1) L'antenne doit être installée de telle sorte qu'une distance de 20 cm est respectée entre l'antenne et les utilisateurs, et 2) Le module émetteur peut ne pas être coïmplanté avec un autre émetteur ou antenne. Tant que les 2 conditions ci-dessus sont remplies, des essais supplémentaires sur l'émetteur ne seront  pas  nécessaires.  Toutefois,  l'intégrateur  OEM  est  toujours  responsable  des  essais  sur son produit final pour toutes exigences de conformité supplémentaires requis pour ce module installé.  IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then  the Canada authorization  is no longer considered valid and the  IC ID  can  not 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. NOTE IMPORTANTE: Dans le cas où ces conditions ne peuvent être satisfaites (par exemple pour certaines configurations d'ordinateur portable ou de certaines co-localisation avec un autre émetteur), l'autorisation du Canada n'est plus considéré comme valide et l'ID IC ne peut pas être utilisé sur le produit final. Dans ces circonstances, l'intégrateur OEM sera chargé de réévaluer le produit final (y compris l'émetteur) et l'obtention d'une autorisation distincte au Canada.
