FCC Caution. § 15.19 Labelling requirements. This device 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. § 15.21 Information to user. Any Changes or modifications not expressly approved by the party responsible for compliance PDF pdfFactory Pro www.fineprint.cn could void the user's authority to operate the equipment. § 15.105 Information to the user. 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 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. The MSi4432 module is designed to comply with the FCC statement. FCC ID is 2AC6H4432‐A. The host system using MSi4432, should have label indicated contains the module’s FCC ID This radio module must not installed to co‐locate and operating simultaneously with other radios in host system , additional testing and equipment authorization may be required to operating simultaneously with other radio.
