This device is classified as a portable device and is subject to SAR evaluation requirements unless it meets the exclusion thresholds. EDR: Worse case output power is as below: [2402MHz: -1.16dBm] Maximum output power is -1.16dBm (0.77 mW). (0.77 mW /5mm)·[√2.402(GHz)]= 0.24 <3.0 for 1-g SAR. BLE: Worse case output power is as below: [2402MHz: -2.19dBm] Maximum output power is -2.19dBm (0.60 mW). (0.60 mW /5mm)·[√2.402(GHz)]= 0.19 <3.0 for 1-g SAR. Then SAR evaluation is not required.
