How To Take Proper Measurements
For the most accurate blood pressure measurement:
Sit comfortably on a chair. Rest your arm on the table. Do not cross your
legs. Keep your feet on the floor and straighten your back.
Relax before measurement.
Place the center of the cuff at the same height as your heart.
Remain still and keep quiet during measurement.
Do not measure immediately after physical exercise or a bath. Rest before
taking the measurement.
Try to measure your blood pressure at the same time every day.
Measurement
During measurement, it is normal for the cuff to feel very tight. (Do not be
alarmed).
After Measurement

If your systolic pressure is expected to exceed 230 mmHg, use this
procedure.
1.
Place the cuff on the arm (preferably the left arm).
2.
Press and hold the START button.
Release the button when the average
of all the data in memory is displayed.
Press and hold the START button
again until a number about 30 to 40
mmHg higher than your expected
systolic pressure appears.

center of the cuff will be at the same
height as your heart.
Relax for about five or ten minutes before taking a measurement. If you
are excited or depressed by emotional stress, the measurement will
reflect this stress as a higher (or lower) than normal blood pressure
reading and the pulse reading will usually be faster than normal.
An individual's blood pressure varies constantly, depending on what you
are doing and what you have eaten. What you drink can have a very
strong and rapid effect on your blood pressure.
This device bases its measurements on the heartbeat. If you have a very
weak or irregular heartbeat, the device may have difficulty determining
your blood pressure.
Should the device detect a condition that is abnormal, it will stop the
measurement and display an error symbol. Refer to page 4 for the
description of the symbols.
This blood pressure monitor is intended for use by adults only. Consult
with your physician before using this device on a child. A child should not
use this device unattended.

What Is An Irregular Heartbeat
The device provides a blood pressure and pulse rate measurement even
when an irregular heartbeat occurs. An irregular heartbeat is defined as
a heartbeat that varies by 25% from the average of all heartbeats during
the blood pressure measurement. It is important that you be relaxed,
remain still and do not talk during measurements.
Note: We recommend contacting your physician if you see this
indicator frequently.

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 first 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:
Do not smoke
Exercise regularly
Reduce salt and fat intake
Have regular physical checkups
Maintain proper weight
Why Measure Blood Pressure At Home?
Blood pressure measured at a clinic or doctor's office 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 influences on blood pressure readings, supplements the doctor's
readings and provides a more accurate, complete blood pressure history.
