Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 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 device is compliant with Industry Canada's RSS standards for license-exempt radio apparatuses. Authorized use depends on the following two conditions: (1) the device must not create radio interference, and (2) the device user must accept all radio interference, even if this interference could potentially impair its functioning. 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. —Consult the dealer or an experienced radio/TV technician for help. To comply with FCC RF exposure compliance recommendations, a separation distance of at least 20 cm must be maintained between the antenna of this device and all persons.

Directives d’installation Adaptateur volumétrique intelligent pour compteur de gaz à membrane Compteur de gaz volumétrique Modèles : VM3010, VM3020 Ne pas laver à pression AVERTISSEMENT Afin de garantir un environnement sûr et antidéflagrant et d'assurer la conformité aux certifications (page 1), les exigences ci-dessous doivent être remplies sans faute : 1. La plage de température ambiante est de -40 ºC ≤ Tamb ≤ +60 ºC, 2. L’appareil ne doit pas être installé dans un endroit où les conditions extérieures sont propices à l’accumulation de charge électrostatique (dans certaines circonstances extrêmes, le boitier de plastique pourrait accumuler un niveau de charge électrostatique pouvant s'enflammer), 3. Ne pas frottez. L’équipement ne doit être nettoyé qu’avec un chiffon humide. INSTALLATION Respectez toujours les réglementations et normes locales. Si nécessaire, consultez un expert certifié pour vous assurer que votre installation est conforme.

Toute modification n’ayant pas été approuvée expressément par la partie responsable de la conformité peut invalider le droit d’employer cet équipement accordé à l’utilisateur. Son opéra- tion est sujettes aux deux conditions suivantes : (1) cet appareil ne doit pas occasionner de brouillage préjudiciable et (2) cet appareil doit accepter toutes les interférences reçues, notamment les interférences pouvant provoquer un fonctionnement non désiré. Ce dispositif est conforme aux normes CNR 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. Cet équipement a été testé et déclaré conforme aux limites imposées aux périphériques numériques de classe B stipulées au chapitre 15 du règlement FCC. Ces limites sont conçues pour fournir une protection raisonnable contre les interférences nuisibles dans un environnement résidentiel. Cet équipement génère, utilise et peut émettre des fréquences radio et, s’il n’est pas installé et utilisé conformément aux instructions, peut créer des interférences nuisibles perturbant les communications radio. Toutefois, rien ne permet de garantir l’absence totale d’interférence dans une installation donnée. Si l’équi- pement perturbe la réception de radios ou de télévisions, ce qui peut être vérifié en éteignant et en rallumant l’équipement, l’utilisateur est invité à tenter de faire disparaître ces interférences en recourant à l’une des mesures suivantes: - réorienter ou déplacer l’antenne de réception ; - augmenter l’écart entre l’équipement et le récepteur ; -brancher l’équipement sur une prise située sur un circuit autre que celui auquel est raccordé le récepteur ; - consulter le revendeur ou un technicien expérimenté pour obtenir de l’aide. Pour se conformer aux recommandations de conformité de la FCC/ISDE en matière d’exposition RF, une distance de séparation d’au moins 20 cm doit être maintenue entre l’antenne de cet appareil et toutes personnes.
