Circuit Description The 24MHz crystal oscillator drives the base of Y1. The modulation provided by AC6956C(U2). The output of AC6956C module has the matching network consisting of R10 and R9 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source The antenna consists of a 2.4GHz PCB antenna There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 3.7 Volt primary battery Feature: Frequency Range: 2402MHz-2480MHz Modulation Type: GFSK, π/4-DQPSK, 8DPSK Antenna Type: PCB Antenna Antenna Gain: 2.499dBi Crystal: 24MHz

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: 2401V57813E-RF-00A TR-EM-RF001 Page 55 of 57 Version 3.0 RF EXPOSURE EVALUATION 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 For worst case: 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 -3.5 0.45 5 0.1 3 Yes Result: Compliant
