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. NOTE:​ 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 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. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. The OEM integrator is responsible for compliance testing to Part 15 Subpart B with the module installed and for compliance to any other FCC rules that apply to the host not covered by the module grant of certification. To fulfill FCC Certification requirements, an OEM manufacturer must comply with the following regulations: 1. The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID 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: IMPORTANT: Contains FCC ID: 2ALIR-MU202. 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 (FCC 15.19). Applicable rules: FCC 15.250 Canada (ISED) Regulatory Information IC:26788-MU202 CAN ICES-3 (B)/NMB-3(B) This device complies with Industry Canada’s licence-exempt RSSs. Operation is subject to the following two conditions: (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 présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio exempts de licence. L’exploitation est autorisée aux deux conditions suivantes : 1) l’appareil ne doit pas produire de brouillage; 2) l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en compromettre le fonctionnement. CAUTION: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. The OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). This Module is labelled with its own IC ID. If the IC ID Certification Number is not visible while installed inside another device, then the device should display the label on it referring to the enclosed module. In that case, the final end product must be labelled in a visible area with the following: “Contains Transmitter Module IC:26788-MU202” OR “Contains IC:26788-MU202” Ce module est étiqueté avec son propre ID IC. Si le numéro de certification IC ID n’est pas visible lorsqu’il est installé à l’intérieur d’un autre appareil, l’appareil doit afficher l’étiquette sur le module de référence ci-joint. Dans ce cas, le produit final doit être étiqueté dans un endroit visible par le texte suivant: “Contains Transmitter Module IC:26788-MU202” OR “Contains IC:26788-MU202” This radio transmitter (IC:26788-MU202) has been approved by ISED Canada to operate with the antenna types listed below with the maximum permissible gain indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for tha…
