Driving low or high pin 9 (TX DATA INPUT) the RF carrier modulated in FSK is emitted through antenna in the frequency selected by pin 6 CHANNEL SELECTION.  3. RF Reception Mode  Reception mode is selected by driving low pin 12 (TX/RX) and high pin 11 (ENABLE). The data received are available at pin 10. The change of the RF channel is permits in receive mode.   Device Usage  To take advantage of the performances detailed in the Technical Specifications, and in order to comply with the  operating  conditions  which  characterize  the  Certification,  the  transmitter  must  be  fitted  on  a  printed circuit considering the followings:    DC Supply:    1. The transceiver must be supplied by a very low voltage source, safety protected against short circuits. Maximum voltage variations allowed: 2,3÷3,6V. 2. De-coupling, next to the transmitter, by means of a minimum 100nF ceramic capacitor. 3. Are  preferable low noise  linear voltage regulator circuits. Eventual voltage regulators DC-DC or  AC-DC can decrease the sensitivity level of the receiver.   Ground:  A flooded ground plane must surround the module. The circuit must be double layer, with throughout vias to the ground planes.  Care must be taken to ensure there are no traces or ground planes under the area surrounding the antenna. It is advise to place the antenna side module toward the edge of the host PCB or solder the module with antenna of the edge host pcb. The picture show the PCB design to be follow for the host circuit:

In cases where an OEM seeks the lesser category of a Class A digital device for the final product, the following statement must be included in the final product manual: NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC (Federal Communications Commission) rules.  These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his expense   Instructions du manuel du produit (pour une application OEM) (française)  Cette  section  concerne  les  OEM  produits  finaux  contenant  le  module  "AUR.EL  RTX-915  FSK  FCC  IC", conforme à FCC (Federal Communications Commission) et IC (Industrie Canada). Le manuel du produit final doit contenir la déclaration suivante (ou une déclaration similaire qui a le même sens): AVERTISSEMENT: Les changements ou modifications non expressément approuvés par la partie responsable pour la conformité pourraient annuler l'autorisation de l'utilisateur à utiliser l'appareil. Dans les  cas où  un OEM  cherche limites Classe  B de  FCC (résidentiel)  pour le  produit final,  la déclaration suivante doit être incluse dans le manuel du produit final: NOTE:  Cet  appareil  a  été  testé  et  déclaré  conforme  aux  limites  d'un  appareil  digital  de  classe  B, conformément  à  la  partie  15  des  règles  de  la  FCC.  Ces  limites  sont  conçues  pour  fournir  une  protection raisonnable contre les interférences nuisibles dans une installation résidentielle. Cet  appareil  génère,  utilise  et  peut  émettre  une  énergie  de  radiofréquence  et,  si  non  installé  et  utilisé conformément  aux  instructions,  il  peut  causer  des  interférences  nuisibles  aux  communications  radio. Cependant, il n'y a aucune garantie que l'interférence ne se produira pas dans une installation particulière. Si cet appareil provoque des  interférences nuisibles  à la réception radio  ou de télévision, ce qui peut être déterminé en mettant l'appareil dans/hors tension, l'utilisateur est invité à essayer de corriger l'interférence par une ou plusieurs des mesures suivantes: - Réorienter ou déplacer l'antenne de réception. - Augmenter la distance entre l'appareil et le récepteur. - Connecter l'équipement à une prise sur un circuit différent de celui auquel le récepteur est connecté. - Consulter le revendeur ou un technicien radio / TV expérimenté. Dans les cas où un OEM cherche la catégorie inférieur d'un appareil digital de classe A pour le produit final, la déclaration suivante doit être incluse dans le manuel du produit final: NOTE:  Cet  appareil  a  été  testé  et  déclaré  conforme  aux  limites  de  la  classe  A  des  appareils  digitals, conformément à la partie 15 des règles de la FCC (Federal Communications Commission).  Ces limites sont conçues pour  fournir une protection  raisonnable contre les  interférences nuisibles  lorsque l'appareil  est  utilisé  dans  un  environnement  commercial.  Cet  appareil  génère,  utilise  et  peut  émettre  de l'énergie radiofréquence et, si non installé et utilisé conformément au manuel d'instruction, peut causer des interférences nuisibles aux communications radio. Le  fonctionnement  de  cet  appareil  dans  une  zone  résidentielle  est  susceptible  de  provoquer  des interférences nuisibles, dans ce cas l'utilisateur sera tenu à corriger les interférences à ses frais.
