The unit has been constructed using reliable circuitry and durable materials. Used properly, this unit will provide yeas of satisfactory use. The device is intended for used by adults and adolescents age 12 through 21 years of age to measure the systolic and diastolic blood pressure and pulse rate. All functions can be used safely and values can be read out in one LCD DISPLAY. Measurement position is on adult upper wrist only. The PATIENT is an intended OPERATOR. Blood pressure measurement determined with this device are equivalent to those obtained by a trained observer using the cuff/ stethoscope auscultation method, within the limits prescribed by the Recognized Consensus Standard(IEC 81060-2-30) for electronic sphygmomanometers. Precautions to Ensure Safe, Reliable Operation 1. Do not drop the unit. Protect it from sudden jars or shocks. 2. Do not insert foreign objects into any openings. 3. Do not attempt to disassemble the unit. 4. Do not crush the pressure cuff. 5. If the unit has been stored at temperatures below 0 oC, leave it in a warm place for about 15 minutes before using it. Otherwise, the cuff may not inflate properly. 6. If the unit has been stored at temperatures above 40 oC,leave it in a cool place for about 15 minutes before using it. Otherwise, the cuff may not inflate properly. 7. Do not store the unit in direct sunlight, high humidity or dust. 8.To avoid any possibility of accidental strangulation, keep this unit away from children and do not drape tubing around your neck. 9.Ensure that children do not use the instrument unsupervised; some parts are small enough to be swallowed. 10.Some may get a skin irritation from the cuff taking frequent readings over the course of the day, but this irritation typically goes away on its own after the monitor is removed.t Safety NoticeSafety Notice 34 Important Instructions Before Use 1. Do not confuse self-monitoring with self-diagnosis. Blood pressure measurements should only be interpreted by a health professional who is familiar with your medical history. 2. Contact your physician if test results regularly indicate abnormal readings. 3. If you are taking medication, consult with your physician to determine the most appropriate time to measure your blood pressure. NEVER change a prescribed medication without first consulting with your physician. 4. Individuals with serious circulation problems may experience discomfort. Consult your physician prior to use. 5. For persons with irregular or unstable circulation resulting from diabetes, liver disease, arteriosclerosis or other medical conditions, there may be variations in blood pressure values measured at the wrist versus at the upper arm. Monitoring the trends in your blood pressure taken at either the arm or the wrist is nevertheless useful and important. 6. People suffering from vascular constriction, liver disorders or diabetes, people with cardiac pacemakers or a weak pulse, and women who are pregnant should consult their physician before measuring their blood pressure themselves. Different values may be obtained due to their condition. 7. People suffering from arrhythmias such as atrial or ventricular premature beats or atrial fibrillation only use this blood pressure monitor in consultation with your doctor. In certain cases oscillometric measurement method can produce incorrect readings. 8.Too frequent measurements can cause injury to the patient due to blood flow interference. 9.The cuff should not be applied over a wound as this can cause further injury. 10.DO NOT attach the cuff to a limb being used for IV infusions or any other intravascular access, therapy or an arterio-venous (A- V) shunt. The cuff inflation can temporarily block blood flow, potentially causing harm to the patient. 11.The cuff should not be placed on the arm on the side of a mastectomy. In the case of a double mastectomy use the side of the least dominant arm. 12.Pressurization of the cuff can temporarily cause loss of function of simultaneously used monitoring equipment on the same limb. 13.A compressed or kinked connection hose may cause continuous cuff pressure resulting in blood flow interference and potentially harmful injury to the patient. 14.Check that operation of the unit does not result in prolonged impairment of the circulation of the patient.15. Product is designed for its intended use only. Do not misuse in anyway. 15. Product is designed for its intended use only. Do not misuse in any way. 16. Product is not intended for infants or individuals who cannot express their intentions. 17. Prolonged over-inflation of the bladder may cause ecchymoma of your arm. 18. Do not disassemble the unit or wrist cuff. Do not attempt to repair. 19. Use only the approved wrist cuff for this unit. Use of other wrist cuffs may result in incorrect measurement results. 20. The system might produce incorrect readings if stored or used out- side the manufacturer's specified temperature and humidity ranges. Make sure to store the blood pressure monitor, children, pets and pests are outside of accessible range.
