Circuit Description Battery (DC 3.7V) provides energy for the Bluetooth chip (AD6983B); Crystal oscillator (24MHz) 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. Modulation Technique: GFSK, π/4-DQPSK, 8DPSK

RF EXPOSURE EVALUATION 5.1 Applicable Standard FCC § 15.247 (i) 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 levels in excess of the Commission's guidelines. See §1.1307(b)(1) of this chapter . 5.2 Procedure According to 447498 D04 Interim General RF Exposure Guidance v01, clause 2.1.2- 1-mW Test Exemption: Per §1.1307(b)(3)(i)(A), a single RF source is exempt RF device (from the requirement to show data demonstrating compliance to RF exposure limits, as previously mentioned) if the available maximum time-averaged power is no more than 1 mW, regardless of separation distance. This exemption applies to all operating configurations and exposure conditions, for the frequency range 100 kHz to 100 GHz, regardless of fixed, mobile, or portable device exposure conditions. This is a standalone exemption, and it cannot be applied in conjunction with any other test exemption. 5.3 Measurement Result Frequency (MHz) Conducted output power including Tune- up Tolerance (dBm) Antenna Gain (dBi) The Greater of Conducted Power or ERP 1-mW Test Exemption dBm mW 2402-2480 -11-2.9-110.08 Compliant Note: The Conducted Power includin g Tune-up Tolerance was declared by manufacturer. Result: Compliant. RF Exposure is exemption. ===== END OF REPORT =====
