When the target inflation value is reached, the air is auto-
matically released. The value in the display counts down-
wards.

Wrap the cuff around your bare left arm so that the
green colored band (indicating the centre of the blad-
der) is positioned 1 – 2 cm above your elbow joint on
the inside of your arm (see picture).
As soon as the monitor detects your pulse the ( ) sym-
bol begins to flash.
When the monitor no longer detects your pulse whilst the
cuff pressure is dropping, your systolic and diastolic blood
pressures (upper and lower values) will be displayed.
Important! If you push up your sleeve, ensure it does
not constrict the blood flow in your arm.
The deflation symbol (
) will now flash to indicate the
end of the measurement.
Close the cuff with the fabric fastener. The green area
of the cuff must cover the brachial artery.
When all the air has been released the ( ) symbol
appears on the display and your blood pressure and pulse
will be displayed on the screen for 5 minutes.
The standard-sized cuff is designed for an arm
circumference of 22 – 32 cm. To ensure accurate
readings on arms with a circumference greater than
32 cm a large cuff will be required.
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.

˜ Successive readings
Please leave an interval of at least 2 – 3 minutes should be
made in between two successive readings, otherwise the
blood flow of the arm could be constricted, which would
distort the results of the reading.
Lay your arm on a table or support (e.g. a cushion)
with the palm of your hand facing upwards so that the
cuff is approximately at heart level. In this way you
ensure that the blood pressure measurement ob-
tained is neither artificially high (measurement below
heart level) nor low (measurement above heart level).
Switch off the device by pressing the ON/OFF (
) button.
The device switches off automatically after approximately 5
minutes.
˜ Inflating the cuff
In order to obtain meaningful readings, you should mea-
sure your blood pressure regularly at the same time of day,
ideally every morning and evening.

1. Repeat the measurement keeping
perfectly still. Do not move your arm and
do not speak.
1. A correct reading could not be obtained
because measurement was disturbed by
movement of the body.
• Stress influences your blood pressure, so try to relax
before taking a measurement.
• To compare results, measurements must always be
taken from the same arm.
• Do not place the cuff over thick clothes and do not roll up
your sleeve if it is too tight.
2. Check that the cuff is correctly fitted. Then
repeat the measurement.
2. The cuff is not fitted correctly.
• Align the cuff with the height of your heart (breast
height). If necessary use a pillow or cushion.
• Coldness raises your blood pressure. It is recommended
to measure at room temperature ( +20°C).
• Relax before measurement. If necessary go to the
bathroom before measurement.
3. Remove the item of clothing which cau-
sed the constriction.
3. Your clothing has constricted your blood flow.
4. The unit may be defective. Please have it
examined and, if necessary, repaired by
OMRON Customer Services.
4. There is still air in the cuff when the monitor
is switched off.
• Do not measure directly after bathing.
• If you wish to interrupt measurement prematurely, press

• If you wish to repeat the measurement, follow the same
procedure as before starting at step 4 (Inflating the cuff).
• Blood pressure measurements taken in a moving vehicle
may be influenced by vibration.
Refer to the instructions and then repeat the
measurement.
The blood pressure values displayed are ex-
tremely low or high, or they are implausible.
• If an error has occurred during measurement E is dis-
played. Please refer to the next chapter.
• The monitor should be switched off after measurement
to avoid running down the batteries unnecessarily. If you
forget to do so, the monitor switches itself off automati-
cally after 5 minutes.
The display does not light up when the (
button is pressed.

1. Check the batteries and, if necessary, fit 4
new batteries.
1. The batteries are exhausted.
2. Reinsert the batteries with the +/- poles
the right way round.
2. The +/- poles of the batteries have been
reversed.
3. Clean the battery contacts with a dry cloth.

3. The battery contacts are dirty.
The batteries are weak or exhausted.
Check that the air tube is properly connec-
ted to the monitor. Push the tube connector
firmly into the socket.

Some useful information about blood pressure
What is Blood Pressure?
The accuracy of this blood pressure monitor has been
carefully tested and is designed for a long service life.
It is generally recommended to have the monitor ins-
pected every two years to ensure correct functioning
and accuracy. Please consult your authorised dealer
or the OMRON Customer Service at the address
given on the packaging/attached literature.
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 pres-
sure readings, the SYSTOLIC and DIASTOLIC, are necessary to enable a doctor to evaluate the status of
a patient’s blood pressure.
Many factors such as physical activity, anxiety, or the time of day, can influence
your blood pressure. Blood pressure is typically low in the morning and increases from afternoon to eve-
ning. It is lower in the summer and higher in the winter.
OMRON devices are especially designed for regular
blood pressure monitoring. OMRON therefore has
direct contact with medical specialists and takes
advice, on the design and features of its blood pres-
sure monitors.
Mains adapter
Blood pressure is measured in millimetres of mercury (mmHg) and measurements
are written with the systolic pressure before the diastolic e.g. A blood pressure written
as 140/90, is referred to as 140 over 90 mmHg.

High Blood Pressure
Due to high company quality standards, OMRON con-
siders the main unit as a non-serviceable part becau-
se of the necessity of proper calibration after replace-
ment of high-tech components.
The discovery that you have high blood pressure is more often than not a chance finding. People with high
blood pressure usually feel well unless the blood pressure has been high for some time, and complications
have occurred. Such complications may effect the heart, brain and other important organs. They may bring
on ill health and affect your enjoyment of life. It is because of the complications, rather than the high blood
pressure itself, that this condition is taken so seriously today.
Normal cuff,
Arm circumference 22 – 32 cm
Code: CM
High blood pressure is sometimes referred to as raised blood pressure, elevated blood pressure, or hyper-
tension. Most people with this condition require regular long-term drug treatment, usually in the form of
tablets. Some can lower their blood pressure sufficiently by other means, such as changing diet and life-
style.
People who have high blood pressure, and who also understand their condition, have an advantage. They
are more likely to attend for regular check-ups, to cooperate with advised diets and changes in lifestyle, and
to take medicines correctly. This immediately leads to better health. It is hoped that, by a better understan-
ding of high blood pressure and how it is treated, you will take an active and informed part in your health
care, and so enjoy a better quality of life.

What Causes High Blood Pressure?
Blood pressure is only classed as high if it doesn t go down when you rest. Permanently raised blood pres-
sure can be caused by several factors such as hardening of the arteries, smoking or drinking too much
alcohol. It can also be caused by cholesterol, a type of fat, building up inside your blood vessels and
making them narrower. Being under stress can add to the problem.
High blood pressure is also known to run in families hence if you find you have a high blood pressure it is a
good idea to test other closely related members of your family.

Why is it a Good Thing To Measure Blood Pressure at Home?
Having your blood pressure measured by a doctor can cause anxiety which is a cause itself of high blood
pressure. As a variety of conditions affect blood pressure, a single measurement may not be sufficient for
an accurate diagnosis.
The blood pressure measured first thing in the morning after getting up, before eating and while at rest, is
known as the fundamental blood pressure. In practice it is rather difficult to record the fundamental blood
pressure, but it is important to get readings in an environment that is as close as possible to this.
