FCC §2.1093 - Radiofrequency radiation exposure evaluation: portable devices. 5.1 RF Exposure Standard Requirement: According to §15.247 (i) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’ s guidelines. Routine SAR evaluation refers to that specifically required by § 2.1093, 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 qualify for TCB approval. result = P= Maximum turn-up power in mW F= Channel frequency in GHz D= Minimum test separation distance in mm Test Report 15070784-FCC-H2 Page 8 of 8 5.2 Test Result Bluetooth Mode: Modulation CH Freq (MHz) Conducted Power (dBm) Tune Up Power (dBm) Max Tune Up Power (dBm) Max Tune Up Power (mW) ResultLimit GFSK Low 2402 1.575 2±1 3 1.995 0.62 3 Mid 2441 1.590 2±1 3 1.995 0.62 3 High 2480 3.077 3±1 4 2.512 0.79 3 π /4 DQPSK Low 2402 2.483 2±1 3 1.995 0.62 3 Mid 2441 2.390 2±1 3 1.995 0.62 3 High 2480 3.768 3±1 4 2.512 0.79 3 8-DPSK Low 2402 2.307 2±1 3 1.995 0.62 3 Mid 2441 2.208 2±1 3 1.995 0.62 3 High 2480 3.664 3±1 4 2.512 0.79 3 Result: Compliance No SAR measurement is required.
