Theory of Operation Scale module including the MCU system and weight sensors, responsible for the weight weighing. Communication module including the MCU system and Bluetooth device is responsible for transferring the weight data to the iOS devices. The Bluetooth module is available in the 2.4GHz ISM band Class 2 Radio, compatible with Bluetooth Core Specification Version 3.0 + EDR. This Bluetooth module is design for MFi (The Made for iPod, Made for iPhone and Made for iPad logos) electronic accessory via Bluetooth connectivity. The Bluetooth module Uses on-board ceramic antenna and its center frequency is 2.45GHz. Scale module gets weight data first. These data will be sent to the communication module directly, through the UART. In communication module, the MCU system received and stored the weight data in memory, and then sent the data to the Bluetooth module. There also send control command to the Bluetooth module. These commands are used to set the operating mode of the Bluetooth. The Bluetooth module has its own MCU, memory unit, RF unit. They will send data out through the RF antenna. Installed on the iOS device with specific software, you can receive the data via Bluetooth.

FCC ID: ZRYHS3 IC: 9775A-HS3 Produkte Products RF Exposure Statement: 15044599 001 Page 1 of 1 Client: Andon Health Co., Ltd. No. 31 Changjiang Road, Nankai District Tianjin 300193, P.R. China Test item: Bluetooth Body Scale Identification: HS3 FCC Requirement According to FCC 2.1091, mobile equipment must comply with the following applicable limit for maximum permissible exposure (MPE) specified in FCC 1.1310: Equipment Use Frequency Range Power Density [mW/cm 2 ] Average Time [min] General Population / Uncontrolled Exposure 1.5 – 100GHz 1 6 IC Requirement According to RSS-102 (Issue 4), clause 2.5.2, no routine RF exposure evaluation is required if the transmitter power (e.i.r.p.) is below the following threshold: Frequency Range SAR Limitation [W] Above 1.5GHz 5 Measurement Result The maximum measured transmitter power is the following: Conducted Output Power P out [mW] Maximum Antenna Gain [dBi] P out EIRP [mW] Power Density at 20cm [mW/cm 2 ] 2.98 2.28 5.047 0.001002 Note: The power density S in mW/cm 2 is calculated according to the Friis formula: S = (P out · G) / (4π · D 2 ), where S = power density in mW/cm 2 P out = antenna conducted output power in mW G = antenna gain in linear scale (here: 2.28dBi = 1.69 linear) D = distance between observation point and radiating structure in cm (here: 20cm) Conclusion The device complies with the FCC and IC RF exposure requirements since the maximum transmitter power density is below the FCC limit and the e.i.r.p. power is below the IC RF exposure evaluation exemption threshold. Refer to test report 15045728 001 for more details. TÜV Rheinland (Shanghai) Co., Ltd. 10-15/F, Huatsing Building, No.88, Lane 777, Guangzhong Road West, Shanghai 200072, P.R. China
