Operation is subject to the following two conditions:
This device may not cause interference This device must accept any interference, including interference that may cause undesired operation of the device RF exposure To comply with the FCC RF exposure compliance requirements, this device and its antenna must not be co-located or operating in conjunction with any other antenna or transmitter. Le prsent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence.L'exploitation est autorise aux deux conditions suivantes:
l'appareil ne doit pas produire de brouillage, et l'utilisateur de l'appareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible d'en compromettre le fonctionnement. Pour se conformer aux exigences de conformit RF canadienne l'exposition, cet appareil et son antenne ne doivent pas tre co-localiss ou fonctionnant en conjonction avec une autre antenne ou transmetteur. End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such that 5mm may be maintained between the antenna and users. The final end product must be labeled in a visible area with the following:
Contains IC ID: 8017A-MDBT50Q Instructions to OEM Integrators A User manual provided to the end user must indicate the operating requirements and conditions that must be observed to ensure compliance with the above-mentioned IC RF Exposure guideline. If this module is intended for use in a portable device, integrators are responsible for separate evaluation and/or approval to satisfy IC RF Exposure requirements.
