How to measure your blood pressure
Please remember:
1. Inserting the batteries
Open the battery compartment on the
left-hand side of the monitor by pushing
the cover outwards, applying gentle
pressure.
Self-measurement is not the same as medical treatment! You should
never change the dose of medicines prescribed by your doctor.
•
•
If you suffer from disorders of heart rhythm (arrhythmia), you should consult
your doctor before using this blood pressure monitor. In certain cases the
oscillometric measuring method may produce incorrect readings or no rea-
dings at all.
When inserting the batteries, make sure
that the +/- poles agree with the symbols
in the battery compartment. Use two
identical 1.5 V batteries (type LR03
alkaline).
Pregnant women should only measure their own blood pressure in consul-
tation with their doctor, since the readings may be changed by pregnancy.
If you do not intend to use the monitor
for a prolonged period, you should
remove the batteries.
In some rare cases there are people where this measuring method does
not work due to physical structure. In such cases OMRON recommends you
to consult a doctor.
Holding the

2. Fitting the cuff
If the cuff is not fitted comfortably and firm-
ly, correct measurement is not possible.
Place the cuff on your left wrist with your
thumb pointing up. Align the edge of the
cuff as shown in the diagram.
The remaining part of the wrist cuff can be
conveniently folded back out of the way.
10 - 15mm
Place the wrist cuff on bare skin. Keep it
clear of your clothing but do not roll up
your sleeve.
To measure on the right wrist
Measurement can also be made on the
right wrist. Fit as shown in the diagram.
Hold the bottom part of the cuff as shown
in the diagram and wrap it around your
wrist while pulling so that it fits comfortably.
If your finger
touches the
shoulder, it is
the right level.
(1)Rest your arm across
your chest so that the RX-I
is at the same level as the
heart.
(3)Relax your arm
and shoulder.
(2)Be sure to sit on a chair
and take a correct posture.
(4)Wrap the wrist cuff comfor-
tably.

measurement.
Your blood pressure is measured during
inflation, so it is important not to move. Sit
still and do not move your wrist! Do not talk!
Do not touch the monitor while it is measu-
ring.
Wrist blood pressure is measured at the different region from the usual bra-
chial blood pressure measurement and may show a slightly different value. In
many cases, the difference between the wrist and the brachial blood pressures
can be up to ± 10 mmHg both for the systolic and the diastolic pressures for
healthy people.
The monitor automatically inflates the cuff
and the
measurement is taken within approx. 30
seconds.
Should you forget to turn off the power, it will turn itself off automatically after 2
minutes. The previous reading will remain in the memory even if the batteries
run down or are replaced.
If you wish to repeat the measurement, you should remove the cuff for
at least 3 minutes because if you take the next measurement immediatly,
a slight blood congestion may occur which can lead to incorrect measure-
ments or an error message.
Once the arrow appears in the display the
measurement is finished and deflation of the
cuff takes place.
After this the systolic and diastolic blood
pressure is shown, with the pulse reading.
This reading will be stored in the memory.
Keep a record of your measurements. In this way both you and your doctor
will have an accurate overview of your blood pressure situation.

3. Memory function
The measured and displayed blood pressure and pulse values are auto-
matically stored in the memory.
If there is no measured value in the memory,
the display shown to the right is indicated when
the MEMORY Button "M" is pushed.
The memory can store the values of up to 7 measurements.
Once the memory has 7 measurement values the next reading will be stored
and the oldest reading will be erased.
The measured values stored in the memory will not be erased even when
the batteries are replaced.
4. How to recall previous measured values from the memory
5. How to erase the memory
By pushing the memory button, you can recall and display the measured
values from the memory starting from the last measured value. This
is possible after measurement or directly when device is switched off.
All the measured values stored in the memory can be erased simul-
taneously by operating the Buttons as follows:
While the ( M ) symbol is displayed, push
the MEMORY "M" and the START Buttons
simultaneously and keep on pushing them.
After two seconds, the display shown to the
right is indicated and the measured values
stored in the memory will be erased.
When you push the MEMORY Button "M",
if there is any measured value stored in
the memory, M1 indicates the latest memory
values. The systolic and the diastolic blood
pressures and the pulse are displayed
alternatively.
All stored measurements will be erased. Because this monitor can store
the measured values, you can measure even while you are out, then recall
and use the results after returning home.
In order to recall the values measured
previously, push the MEMORY Button "M"
again.

General information about blood pressure
Systolic blood pressure
(mmHg)
The blood circulation is responsible for supplying the body with oxygen. Blood
pressure is the pressure exerted on the arteries when the blood flows through
them.
Severe hypertension
180
160
140
130
120
Moderate hypertension
Mild hypertension
The higher blood pressure value (= systolic pressure or top value) signifies the
blood pressure produced by contraction of the heart muscle and subsequent
pumping of blood into the arterial system.
Normal systolic value
Normal blood
pressure
The lower blood pressure value (= diastolic pressure or lower value) repre-
sents the blood pressure produced by the relaxation phase of the heart
muscle, during which blood flows back into the heart.

Health and blood pressure
Arterioles
The incidence of hypertension increases with age. In addition, a lack of exer-
cise, excess body fat and high levels of cholesterol (LDL) which sticks to the in-
side to blood vessels, reduces elasticity of these vessels. Hypertension accele-
rates arterial sclerosis, which can lead to very serious conditions such as stroke
and myocardial infarction. For these reasons it is very important to know
whether our blood pressure is within a healthy range. Blood pressure fluctuates
from minute to minute, throughout the day. Therefore it is essential to take
regular readings to help identify an average blood pressure for you.

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
the Figure. (This classification is based on the blood pressure values
measured by sitting on a chair in the outpatient department of a hospital.)
