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 equipment 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. Any changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. Please notice that if the FCC identification 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 FCC ID:2AC23-WKC12 any similar wording that expresses the same meaning may be used. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The module is limited to OEM installation ONLY. The OEM integrator is responsible for ensuring that the end-user has no manual instruction to remove or install module. The module is limited to installation in mobile application. A separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093 and difference antenna configurations. There is requirement that the grantee provide guidance to the host manufacturer for compliance with Part 15B requirements. The module complies with FCC Part 15.247 / Part 15.407 and apply for Single module approval. Trace antenna designs: Not applicable.

(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 prsent appareil est conforme aux CNR dIndustrie Canada applicables aux appareils radio exempts de licence. Lexploitation est autorise aux deux conditions suivantes :

(1) lappareil ne doit pas produire de brouillage;

(2) lutilisateur de lappareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible den compromettre le fonctionnement. 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:12290A- WKC12 any similar wording that expresses the same meaning may be used. l'appareil hte doit porter une tiquette donnant le numro de certification du module d'Industrie Canada, prcd des mots Contient un module d'mission , du mot IC:12290A-

WKC12 ou d'une formulation similaire exprimant le mme sens, comme suit The device for operation in the band 5150-5350 MHz is only for indoor use to reduce the potential for harmful interference to co-channel mobile satellite systems for devices with detachable antenna(s), the maximum antenna gain permitted for devices in the band 5725-5850 MHz shall be such that the equipment still complies with the e.i.r.p. limits as appropriate;

Les dispositifs fonctionnant dans la bande 5150-5350 MHz sont rservs uniquement pour une utilisation lintrieur afin de rduire les risques de brouillage prjudiciable aux systmes de satellites mobiles utilisant les mmes canaux;

pour les dispositifs munis d'antennes amovibles, le gain maximal d'antenne permis (pour les dispositifs utilisant la bande de 5 725 5 850 MHz) doit tre conforme la limite de la p.i.r.e. spcifie, selon le cas;

Cet quipement respecte les limites dexposition aux radiations fixes par la FCC pour un environnement non contrl. Ces quipements doivent tre installs et exploits une distance minimale de 20cm entre le radiateur et votre corps. Cet metteur ne doit pas tre co-localis ni fonctionner en conjonction avec une autre antenne ou un autre metteur. PAGE 3 OF 1 Version 1.0
