Power output listed is ERP for frequencies below 1GHz and EIRP for frequencies above 1GHz. SAR compliance for body-worn operating configurations is limited to the specific configurations tested for this filing. Body-worn operations are restricted to belt-clips, holsters or similar accessories that have no metallic component in the assembly and must provide at least 20 mm separation between the device and the body of the user. End-users must be informed of the body-worn operating requirements for satisfying RF exposure compliance. The highest reported SAR for body-worn and simultaneous SAR accessory are 0.99 W/kg and 1.03 W/kg respectively.
