Circuit Description Battery (DC 3.7V) provides energy for the Bluetooth chip (AB5616A3); Crystal oscillator (26MHz) provides the clock signal for the Bluetooth chip. Bluetooth signals get through a matching circuit, and then transmitted to the space through the antenna (2402-2480MHz). When the product is connected, the product can in two-way communication with other Bluetooth Devices, and then the device’s Bluetooth module sends Bluetooth signals into space, the product receives the Bluetooth signal through an antenna, transmission to the Bluetooth chip via matching circuit.

Shenzhen Accurate Technology Co., Ltd. Report No.: RA230705-38563E-RF-00 Version 7: 2023-01-30 Page 11 of 58 FCC-BT FCC§15.247 (i), §1.1307 (b) &§2.1093 – RF EXPOSURE Applicable Standard According to FCC §2.1093 and §1.1307(b) (1), 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. According to KDB 447498 D01 General RF Exposure Guidance The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where 1. f(GHz) is the RF channel transmit frequency in GHz. 2. Power and distance are rounded to the nearest mW and mm before calculation. 3. The result is rounded to one decimal place for comparison. 4. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test Exclusion. Measurement Result Mode Frequency (MHz) Max tune-up conducted power* (dBm) Max tune-up conducted power* (mW) Distance (mm) Calculated value Threshold (1-g SAR) SAR Test Exclusion BT 2402-2480 6.5 4.47 5 1.4 3.0 Yes Note: The tune-up power was declared by the applicant.
