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: The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications or changes to this equipment. Such modifications or changes could void the users authority to operate the equipment. The output power is so low that no SAR measurement is required. A certified modular has the option to use a permanently affixed, or an electronic label. For a permanently affixed label, the module must be labeled with an FCC ID: 2AAYB-JBA-870V5-1.The OEM manual must provide clear instructions explaining to the OEM the labeling requirements, options and OEM user manual instructions that are required. For a host using a this FCC certified modular with a standard fixed label, if
(1)the modules FCC ID is notvisible when installed in the host, or(2) if the host is marketed so that end users do not have straightforward commonly used methods for access to remove the module so that the FCC ID of the module is visible; then an additional permanent label referring to the enclosed module:Contains Transmitter Module FCC ID: 2AAYB-JBA-870V5-1 or Contains FCC ID: 2AAYB-JBA-870V5-1 must be used. The host OEM user manual must also contain clear instructions on how end users can find/or access the module and the FCC ID. Host product is required to comply with all applicable FCC equipment authorizations regulations, requirements and equipment functions not associated with the transmitter module portion, compliance must be demonstrated to regulations for other transmitter components within the host product; to requirement for unintentional radiators (15B). To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. If a host was previously authorized as an unintentional radiator under the Declaration of Conformity procedure without a transmitter certified module and a module added, the host manufacturer is responsible for ensuring that the after the module is installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements. Since this may depend on the details of how the module is integrated with the host, we suggest the host device to recertify part 15B to ensure complete compliance with FCC requirement: part 2 Subpart J Equipment Authorization Procedures, KDB784748 D01 v07,and KDB 997198 about importation of radio frequency devices into the United States.
