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: 2.37dBm] Maximum output power is 2.37dBm (1.72 mW). (1.72 mW /5mm)·[√2.402(GHz)]= 0.53 <3.0 for 1-g SAR. Then SAR evaluation is not required.
