Korotkoff Sound Blood Pressure Monitor User Manual KSY3100 | KSY3100B | KSY3120 | KSY3120B | KSY3128B | KSY3100A Beijing Hanvon Health Technology Co., Ltd. ● Thank you for purchasing Hanvon Korotkoff Sound Blood Pressure Monitor. ● To ensure safe usage of this product, please read this user manual carefully before use. ● After reading, please keep it carefully for future reference. ● This Blood Pressure Monitor utilizes the electronic Korotkoff sound method for measurement. ● This product is suitable for scenarios such as families, hospitals, and clinics, etc. Intended purpose: The device is a digital monitor intended for use in measuring the systolic pressure and diastolic pressure, as well as the pulse rate of adults and adolescents via a non-invasive auscultatory method in medical facilities or at home, with an inflatable cuff wrapped around the upper arm for arm circumfer- ences ranging from 22 to 42 cm. The measurement ranges of the device are systolic pressure 40 ~ 280 mmHg (supported by automatic mode for 40 to 210 mmHg and manual mode for 210 to 280 mmHg), diastolic pressure 20 ~ 220 mmHg, and pulse rate 40 ~ 240 beats/min. The device can detect Irregular Heart Beat(IHB) and Tachycardia. Models KSY3128B and KSY3100A additionally support Atrial Fibrillation detection. Intended Patient: Adults and adolescents （ ＞ 12 years） Clinical Benefit: Patient’s blood pressure can be measured non-invasively and simply in the home and clinical environment. Contraindications: DO NOT use this monitor on an injured arm or an arm under medical treatment. DO NOT apply the arm cuff on your arm while on an intravenous drip or blood transfusion. DO NOT use this monitor on infants, toddlers, children or persons who cannot express themselves. Structural Composition: It is composed of the main unit, the cuff, and the AC adapter (optional). 1.2 Component Description Main Unit (front)Main Unit (left) 1.

Product Description The EUT is a Korotkoff Sound Blood Pressure Monitor Operation Frequency: 2402 – 2480 MHz Modulation Type: GFSK Antenna gain: 3.78dBi Antenna Designation: PCB antenna Power Rating DC 3.7V from battery, DC 5V from adapter Adapter Model: GJ12WA-0500100UW Input: AC 100-240V 50/60Hz 0.3A Output: DC 5V 1A Battery 3.7V Hardware Version N/A Software Version N/A 1.2 TEST FACTORY SHENZHEN STS TEST SERVICES CO., LTD Add. : 101, Building B, Zhuoke Science Park, No.190 Chongqing Road, ZhanChengShequ, Fuhai Sub-District, Bao’an District, Shenzhen, Guang Dong, China FCC test Firm Registration Number: 625569 IC test Firm Registration Number: 12108A A2LA Certificate No.: 4338.01 Page 6 of 8 Report No.: STS2512341H01 2. FCC 47CFR §2.1093 REQUIREMENT 2.1 TEST STANDARDS The limit for Maximum Permissible Exposure (MPE) specified in KDB 447498 D01 General RF Exposure Guidance v06 is followed. The gain of the antennas used in the product is extracted from the Antenna data sheets provided and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis Transmission formula is far field assumption, the calculated result of that is an over-prediction for near field power density. It is taken as worst case to specify the safety range. 2.2 LIMIT Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. Page 7 of 8 Report No.: STS2512341H01 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 f(GHz) is the RF channel transmit frequency in GHz. Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.
