FCC ID : VO8-TF500 Bluetooth (Portable device) According to §15.247(e)(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. According to KDB 447498 (2)(a)(i) Frequency Range Low Frequency (MHz) High Frequency(MHz) Center frequency (MHz) 60/f SAR Limitation (mw) 2402 2480 2441 24.5 Maximum measured transmitter power: Conducted Power(dBm)Cable Loss(dB) Max Antenna Gain (dBi)EIRP (mw) -4.20 2.5 0 0.67 Remark：EIRP=P+C+G=-1.7dBm=0.67mW Threshold at which no SAR required is 25 mw. Maximum Tx power is 0.67 mw EIRP. Conclusion: No SAR is required. TRANSMISSION EVALUATION Pass
