| Single Modular Approval. Output power listed is Conducted Peak for BLE and Conducted for WLAN. This device supports WLAN 20/40 bandwidth modes. Separate evaluation must be required for any portable configuration. When used in mobile applications, the module antenna(s) must be installed to meet the RF exposure compliance separation distance of 20 cm and any additional testing and authorization process as required. Compliance of this device in all final host configurations is the responsibility of the Grantee. The host integrator must follow the integration instructions provided by the module manufacturer and ensure that the composite-system end product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules and to KDB Publication 996369. The host integrator is instructed to ensure that the end user has no manual instructions to remove or install the device. Co-location of this module with other transmitters that operate simultaneously are required to be evaluated using the FCC multi-transmitter procedures. |
