The digits representing the “Minute” on the time display section will flash. 6 Set the “Minute”. Press Press to set the current minute. . This will complete the clock setting procedure. The device automatically turns off power. • The “Second” will be set to 00 at the moment when If is pressed.
Blood pressure varies with posture, the time of day and numerous other factors. It is recommended that you measure your blood pressure at the same time each day in the same posture. Take a deep breath and then relax before measuring blood pressure. Make sure that your posture is correct. Lightly open your hand on the table with palm up and relax your fingers. Level the blood pressure monitor to your heart. Fold up a towel and put it between your elbow and wrist to steady your forearm.
HOW TO WRAP THE WRIST CUFF Wrap the wrist cuff around your wrist properly. Improper wrapping of the cuff may result in measuring errors. 1 Unfasten and open the wrist cuff. 2 Wrap the cuff around your left wrist so that the monitor is positioned on the inside of your wrist. • Wrap the wrist cuff on bare skin. • The wrist cuff is designed to fit wrists from 13.5 to 19.5 cm in circumference. 3 Loosely fit the wrist cuff by pulling the end of the cuff.
4 Position the top edge of the cuff approximately 1 to 2 cm away from the crease of your wrist. 5 Secure the wrist cuff with the Velcro. • If the wrist cuff is wrapped too loose or tight, errors or incorrect readings may result.
HOW TO MEASURE YOUR BLOOD PRESSURE Your blood pressure can be readily measured with the push of a button. 1 Wrap the wrist cuff around your left wrist. ( See page 14 “HOW TO WRAP THE WRIST CUFF”.) If you have a weak pulse: Take a measurement so that the center of the unit is positioned over the artery located on your wrist.

What is blood pressure? The heart is a pump that circulates blood throughout your body. Blood is pumped from the heart into the arteries. This pressure is called the arterial blood pressure, which represents, in general, blood pressure. Blood pressure is indicated by several kinds of pressures such as: systolic pressure that occurs when the heart pumps blood; and diastolic pressure that occurs just when blood returns to the heart.
QUESTIONS AND ANSWERS ON BLOOD PRESSURE Q A Q A Why is the blood pressure measured at home different from that measured at the doctors or a hospital? When you have a doctor or nurse measure your blood pressure, the pressure value is likely to be 10 to 20 mmHg higher than usual because of concern and nervousness. To know what affects blood pressure is crucial to your health monitoring.
