FCC ID : VO8-R2 RF Exposure Applicable Standard According to §1.1307(b)(5), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. This is a Portable device. The Section 4.3.1 and Appendix A of KDB447498 D01 V05 was used as the guidance. Calculation Result (Worse Case): [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] =1.96/5 * 1.56=0.61 this value is less than 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR. The SAR measurement is not necessary.
