User manual MEDION BLOOD PRESSURE MONITOR MD 42780

[. . . ] Only start the air supply once the sleeve is attached correctly to the wrist. Never press the START but ton if the sleeve is not attached. never try to open and/or repair the appliance yourself. Do not make any changes to settings insi de the unit using your own tools. [. . . ] The doctor will tell you which blood pressure level is normal for you, and which peculiarities you should report if they occur. Do not implement any therapeutic measures without having spoken to a doctor first. NEVER take medicine in particular as a result of the measured values without asking a doctor for advice! Attention is advised for the following persons: Persons with high blood pressure, diabetes, liver disease, hardened arteries, poor circulation and so on. Your blood measuring unit contains high quality technical components and materials for measuring pressure, processing the signals and displaying the values on a liquid crystal display. The unit measures blood pressure indirectly using a sleeve around the wrist. Inflating the sleeve pres ses the arteries together so that no more blood can flow through them. If the pressure in the sleeve is then reduced, this creates a relation between the sleeve pressure and the blood pressure. The unit has electronic step valves that can detect even slight changes during the measurement, which can be evened out using the sleeve pressure. By reducing the pressure step by step, fluctuati ons in the sleeve are recorded by the unit and inclu ded in the assessment. If no fluctuations are recorded for a step, the air pressure is reduced. Existing fluctuations are assessed at the corre sponding step level until they can be determined precisely. Blood pressure measured at the wrist can differ from the pressure measured at the upper arm, for example because the strength of the arteries in the wrist and upper arm may differ. In many cases, the difference for healthy persons can be ±10 mmHg of the systolic and diastolic blood pressure. The change battery sign appears if the batteries need to be changed. The pulse sign appears when the pulse is display ed. The memory sign indicates the number of the me mory space. You can save up to 90 measurements including the date and time in the unit's memory. The error sign appears if there is an operation or unit error. Pay at tention to the polari ty (the negative terminal faces the spring). Change the batteries when the battery change sign is displayed. You should also change the batteries if nothing ap pears on the display when you turn the unit on. [. . . ] the data is also deleted if you remove the batteries. The saved data remains stored if you press the on/ off button. Keep your arm and the unit at heart height Remain quiet for the du ration of the measure ment (do not move or speak). replace the batteries with new alkali type AAA batteries. [. . . ]
