Limited module procedures not applicable
Trace antenna designs Not applicable.
射频暴露注意事项
本设备符合 FCC 针对非受控环境制定的移动辐射暴露限制。本设备的安装和操作应使辐射器和身体之间的距离至少为 20 厘米。如果模块安装在便携式主机中,则需要进行单独的 SAR 评估,以确认符合相关的 FCC 便携式 RF 暴露规则。
天线
The following antennas have been certified for use with this module; antennas of the same type with equal or lower gain may also be used with this module. The antenna must be:
标签和合规信息
The final end product must be labeled in a visible area with the following: “Contains FCC ID: 2BRL3-MC26D”. The grantee’s FCC ID can be used only when all FCC compliance requirements are met.
有关测试模式和其他测试要求的信息
该发射器在独立移动射频暴露条件下进行测试,任何与其他发射器共置或同时传输或便携式使用都需要单独的 II 类许可变更重新评估或新的认证。
附加测试,第 15 部分 B 分部免责声明
- 主机制造商负责确保安装模块的主机系统符合系统的所有其他适用要求,例如第 15B 部分。
- 重要提示:如果无法满足这些条件(例如amp某些笔记本电脑配置或与其他发射器共置),则 FCC 授权不再被视为有效,FCC ID 不能用于最终产品。在这种情况下,OEM 集成商将负责重新评估最终产品(包括发射器)并获得单独的 FCC 授权。
致最终用户的手册信息
OEM 集成商必须注意不要在集成该模块的最终产品的用户手册中向最终用户提供有关如何安装或移除此 RF 模块的信息。
最终用户手册应包括本手册中所示的所有必需的监管信息/警告。
OEM/主机制造商责任
OEM/主机制造商最终负责主机和模块的合规性。 最终产品必须根据 FCC 规则的所有基本要求(例如 FCC 第 15 部分 B 子部分)重新评估,然后才能投放美国市场。 这包括重新评估发射器模块是否符合 FCC 规则的无线电和 EMF 基本要求。 未经重新测试作为多无线电和组合设备的合规性,不得将此模块并入任何其他设备或系统
联邦通讯委员会
本设备符合 FCC 规则第 15 部分的规定。操作需遵守以下两个条件:
- 本设备不得造成有害干扰,并且
- 本设备必须承受任何收到的干扰,包括可能导致不良操作的干扰。
任何未经合规负责方明确批准的更改或修改都可能使用户操作该设备的权限失效。
笔记: 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 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:
- 重新调整或重新定位接收天线。
- 增加设备与接收器之间的距离。
- 将设备连接到与接收器不同电路的插座上。
- 请咨询经销商或经验丰富的无线电/电视技术人员寻求帮助。
本设备符合 FCC 针对不受控环境所规定的辐射暴露限制。本设备的安装和操作应使辐射器和身体之间的距离至少保持 20 厘米。
