(OEM) Integrator has to assure compliance of the entire end product incl. theintegrated RF Module. Additional measurements (15B) and/or equipment authorizations (e.gVerification) may need to be addressed depending on co-location or simultaneous transmissionissues if applicable. (OEM) Integrator is reminded to assure that these installation instructionswill not be made available to the end user of the final host device.With the documented max output power this RF Module meets the FCC SAR Exemption, so itcomply with any applicable RF exposure requirements in its final configuration. The RF Module ispowered by battery, the antenna is PCB antenna and the antenna gain is 2.21dBi. The final hostdevice, into which this RF Module is integrated" has to be labeled with an auxiliary label stating
