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. FCC Part 15.105 statement (Class B) 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.

(1) lappareil ne doit pas produire de brouillage, et

(2) lutilisateur de lappareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible den compromettre le fonctionnement. RF Exposure The antenna (or antennas) must be installed so as to maintain at all times a distance minimum of at least 20 cm between the radiation source (antenna) and any individual. This device may not be installed or used in conjunction with any other antenna or transmitter. l'exposition aux RF Lantenne (ou les antennes) doit tre installe de faon maintenir tout instant une distance minimum de au moins 20 cm entre la source de radiation (lantenne) et toute personne physique. Caution Any changes or modifications to this device not explicitly approved by manufacturer could void your authority to operate this equipment. Les changements ou modifications de cet appareil non expressment approuv par le fabricant peuvent annuler votre droit utiliser cet quipement. tiquetage du produit final (IC) Le module LCU-001 est tiquet avec sa propre identification FCC et son propre numro de certification IC. Si lidentification FCC et le numro de certification IC ne sont pas visibles lorsque le module est install lintrieur dun autre dispositif, la partie externe du dispositif dans lequel le module est install devra galement prsenter une tiquette faisant rfrence au module inclus. Dans ce cas, le produit final devra tre tiquet sur une zone visible avec les informations suivantes :
