3. Using the Unit
• Your blood pressure monitor includes an irregular heartbeat feature. Irregular heartbeats
can influence the results of the measurement. The irregular heartbeat algorithm
automatically determines if the measurement is usable or needs to be repeated. If the
measurement results are affected by irregular heartbeats but the result is valid, the result is
shown together with the irregular heartbeat symbol ( ). If the irregular heartbeats cause
the measurement to be invalid, no result is shown. If the irregular heartbeat symbol ( )
is shown after you have taken a measurement, repeat the measurement. If the irregular
heartbeat symbol ( ) is shown frequently, please make your doctor aware of it.
• If you move during measurement, the movement error symbol ( ) will appear on the
display. Keep still and repeat the measurement.
Note: Wait 2-3 minutes before taking another blood pressure measurement. Waiting between readings
allows the arteries to return to the condition prior to taking the blood pressure measurement.
Warning:
Self-diagnosis of measured results and treatment are dangerous. Please follow the instructions of
your doctor.

Some Useful Information about Blood Pressure
What is Blood Pressure?
Blood pressure is a measure of the force of blood flowing against the walls of the arteries.
Arterial blood pressure is constantly changing during the course of the heart’s cycle.
The highest pressure in the cycle is called the Systolic Blood Pressure; the lowest is the
Diastolic Blood Pressure.
Both pressure readings, the Systolic and Diastolic, are necessary to enable a doctor to
evaluate the status of a patient’s blood pressure.
What is Irregular Heartbeat?
An irregular heartbeat is a heartbeat rhythm that varies by
more than 25% from the average heartbeat rhythm detected
while the unit is measuring the systolic and diastolic blood
pressure.
If such an irregular rhythm is detected more than twice
during measurement, the irregular heartbeat symbol ( )
appears on the symbol when the measurement results are

What is Arrhythmia?
Arrhythmia is a condition where the heartbeat rhythm is abnormal due to flaws in the bio-
electrical system that drives the heartbeat. Typical symptoms are skipped heartbeats,
premature contraction, an abnormally rapid (tachycardia) or slow (bradycardia) pulse.

7. Some Useful Information about Blood Pressure
Why is it a Good Thing to measure Blood Pressure at Home?
Many factors such as physical activity,
anxiety, or the time of day, can
influence your blood pressure. A single
measurement may not be sufficient for
an accurate diagnosis. Thus it is best to
try and measure your blood pressure at
the same time each day, to get an
accurate indication of any changes in
blood pressure. Blood pressure is
typically low in the morning and
increases from afternoon to evening. It
is lower in the summer and higher in the winter.

Classification of Blood Pressure by the World Health Organization
The World Health Organization (WHO) and the
International Society of Hypertension (ISH) developed
the Blood Pressure Classification shown in this figure.
This classification is based on the blood pressure
values measured on people in a sitting position in
outpatient departments of hospitals.
Note: There is no universally accepted definition of hypotension.
However, those having the systolic pressure below
100 mmHg are assumed as hypotensive.
