Grant Notes

Output power listed is conducted. This is a portable device. The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. End users must be provided with specific operating instructions for satisfying RF exposure compliance. 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. End-users must be informed of the body-worn operating requirements for satisfying RF exposure compliance. The highest reported SAR values for head, body, hotspot and simultaneous transmission use conditions are 0.90 W/kg, 0.08 W/kg, 0.08 W/kg and 1.04 W/kg respectively.
