Output power listed is conducted. SAR compliance for body-worn operating conditions 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 a minimum separation distance of 0 mm between the device and the body. End-users must be informed of the body-worn operating requirements for satisfying RF exposure compliance. The highest reported SAR values for head, body-worn accessory, product specific (hotspot) and simultaneous transmission use conditions are 0.45 W/kg, 0.18 W/kg, 0.18 W/kg and 1.09 W/kg respectively. This device supports 20 MHz bandwidth modes.
