RF EXPOSURE EVALUATION EUT Specification EUT Ture wireless earbuds with charging case Model Number SL319, SL283, 2774,IT226, CPP-5026, CH-4579, 116435, 116436, EHE-OW19BK, T328 FCC ID 2ABHA0059 Antenna gain (Max) -0.58dBi Operation Frequency 2402-2480MHz Input Rating DC 3.7V Battery Classification Per §15.247(i), §2.1093 Stipulated Test Standard Kind of Device: Bluetooth Ver.5.0 Modulation GFSK, π/4-DQPSK Max. output power 1.27dBm(0.00134W) Test 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 quality for TCB approval. One antenna is available for the EUT. The minimum separation distance is 5mm.
