Grant CommentsOutput power listed is conducted. The antenna used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter, except in accordance with FCC multi-transmitter product procedures. SAR compliance for wrist-worn and next to mouth operating conditions is limited to the specific configurations tested for this filing. End-users must be informed of the wrist-worn and next to mouth requirements to satisfy RF exposure compliance. The highest reported SAR for wrist-worn exposure conditions is 0.79W/kg and the highest report SAR for simultaneous transmission conditions is 3.23W/kg. The highest reported SAR for next to mouth exposure conditions is 0.33W/kg and the highest report SAR for simultaneous transmission conditions is 0.92W/kg. This device supports 20MHz bandwidth mode only.
