| Grant Comments | Class II Permissive Change : This change is to incorporate this Module into a new host(Brand / model : FluentPet / B100) as described in this filing. The Power Density and SAR data in this filing is applicable to demonstrate compliance for body operating conditions and is limited to the specific configuration tested for this filling. SAR has been evaluated at 0 mm. End end-users must be provided with specific operating instructions for satisfying RF exposure compliance requirements. The highest reported SAR for body and simultaneous transmission exposure conditions are 1.31 W/kg and 1.33 W/kg, respectively. Modular Approval. Output power listed is conducted. This transmitter is approved for use in mobile RF exposure category configurations with the antenna(s) installed to provide a separation distance of at least 20 cm from all persons. This grant is valid only when the module is sold to OEM or OEM integrator. Co-location of this module with other transmitters that operate simultaneously is required to be evaluated using the FCC multi-transmitter procedures. The integrator must be provided with specific information required to satisfy RF exposure compliance for final host devices and installations. Compliance of this device in all final host configurations is the responsibility of the Grantee. Installation of this device into portable RF Exposure category host devices requires the submission of a Class II permissive change or new application. This device supports 20 MHz and 40 MHz bandwidth modes. |
