Using the Monitor
Applying the Cuff
1. Wrap the cuff around your wrist about 1 cm above your hand as shown in the
gure at the right.
2. Apply the cuff tightly using the Velcro strip.
Note: For accurate measurements, apply the cuff tightly and measure on a bare wrist
How to Take Accurate Measurements
qRemain still and keep quiet during measurement.
qSit down in a comfortable position. Place your elbow on a table with your palm facing upward and the cuff is at the
same level as your heart.
qRelax for about ve to ten minutes before measurement. If you are excited or depressed by emotional stress, the
measurement will reect this stress as a higher (or lower) than normal blood pressure reading and the pulse reading
will usually be faster than normal.
qTry to measure your blood pressure at about the same time every day.
qAn individual’s blood pressure varies constantly, depending on what they are doing, what they have eaten and what
they drink can have a very strong and rapid effect on your blood pressure.
qDo not measure immediately after physical exercise or a bath. Rest for twenty or thirty minutes before taking the
measurement.
qDo not cross your legs. Keep your feet at on the oor and straighten your back.
qThis device bases its measurements on the heartbeat. If you have a very weak or irregular heartbeat, the device may
have difculty determining your blood pressure.

What is the IHB/AFib Indicator?
When the monitor detects an irregular rhythm during the measurements, the IHB/AFib indicator will appear on the display
with the measurement values.
Note: We recommend contacting your physician if you see this IHB/AFib indicator frequently.
What is AFib?
The heart contracts due to electrical signals occurring in heart and sends blood through the body. Atrial brillation (AFib)
occurs when the electrical signal in the atrium becomes confused and leads to disturbances in the pulse interval. AFib can
cause blood to stagnate in the heart, which can easily create clots of blood, a cause of stroke and heart attack.
Pressure Bar Indicator
The indicator monitors the progress of pressure during measurement.

About Blood Pressure
What is Blood Pressure?
Blood pressure is the force exerted by blood against the walls of the arteries. Systolic pressure occurs when the heart
contracts. Diastolic pressure occurs when the heart expands. Blood pressure is measured in millimeters of mercury
(mmHg). One’s natural blood pressure is represented by the fundamental pressure, which is measured rst thing in the
morning while one is still at rest and before eating.

What is Hypertension and How is it Controlled?
Hypertension, an abnormally high arterial blood pressure, if left unattended can cause many health problems including
stroke and heart attack. Hypertension can be controlled by altering lifestyle, avoiding stress, and with medication under a
doctor’s supervision. To prevent hypertension or keep it under control:
Why Measure Blood Pressure at Home?
Blood pressure measured at a clinic or doctor’s ofce may cause apprehension and can produce an elevated reading, 25
to 30 mmHg higher than that measured at home. Home measurement reduces the effects of outside inuences on blood
pressure readings, supplements the doctor’s readings and provides a more accurate, complete blood pressure history.
Blood Pressure Variations
An individual’s blood pressure varies greatly on a daily and seasonal basis.
It may vary by 30 to 50 mmHg due to various conditions during the day. In
hypertensive individuals variations are even more pronounced. Normally, the
blood pressure rises while at work or play and falls to its lowest levels during
sleep. So, do not be overly concerned by the results of one measurement.
Take measurements at the same time every day using the procedure
described in this manual to get to know your normal blood pressure. Regular
readings give a more comprehensive blood pressure history. Be sure to note
the date and time when recording your blood pressure. Consult your doctor
to interpret your blood pressure data.
