Routine SAR evaluation refers to that specifically required by ß2.1093, using measurements or computer simulation. When routine SAR evaluation is not required, portable transmitters with output power greater than the applicable low threshold require SAR evaluation to quality for TCB approval. One antenna is available for the EUT. The minimum separation distance is 5mm. BR + EDR: The Product unsupported at the same time to Transmitting. According to KDB 447498, and no simultaneous SAR measurement is required.
