How to Sit Correctly When Taking a Measurement
Correct posture during measurement is necessary to get accurate
results.
Notes:
• Measurements should be taken in a quiet place and you should be in
a relaxed, seated position. Make sure that the room is not too hot or
too cold.
• Avoid eating, drinking alcohol, smoking, or exercising for at least 30
minutes before taking a measurement.
• Do not move or talk during measurement.
Correct
Posture
Sit upright
with your
back straight.
The gap between the
chair and the top of the
table should be between
25cm to 30cm.
Remove tight fitting clothing from
your upper arm, and any thick
clothing such as a sweater.
Do not place the cuff over thick
clothes and do not roll up your
sleeve if it is too tight.
Place your arm on a table so
that the cuff will be at the same
level as your heart.
EN
17
Page 18
3.Using the Unit
Incorrect Posture
• Arched back (leaning forwards)
• Sitting cross-legged
• Sitting on a sofa or at a low table
so that you tend to lean forward
These situations could lead to higher blood pressure
values due to strain or the arm cuff being lower than the
heart.
If the arm cuff is at a lower position than your heart use
cushions etc., to adjust the height of your arm.

Page 19
3.Using the Unit
3.2
Applying the Arm Cuff
Notes:
• Be sure to wrap the arm cuff correctly so that you get accurate results.
• Measurements can be taken in light clothing. However, please remove
thick clothes, such as sweaters, before taking a reading.
• You can take a measurement on either your left or right arm. The
blood pressure can differ between the right arm and the left arm and
therefore also the measured blood pressure values can be different.
Omron recommends to always use the same arm for measurement. If
the values between the two arms differ substantially, please check
with your doctor which arm to use for your measurement.
Taking measurements on the left arm
1.
Open two Air connector caps, then insert the air plugs of the arm
cuff and the inflation bulb into their respective air connectors.
Note: Be sure to use the appropriate size arm cuff. Should
you require a small cuff, ensure that the small bulb is
used together with the small cuff. Please refer to
Chapter 7.
EN
19
Page 20
3.Using the Unit
2.Put your left arm through the cuff
loop.
Note: If the cuff is not assembled,
pass the end of the cuff
furthest from the tubing
through the metal D-ring to
form a loop. The smooth
cloth should be on the inside
of the cuff loop.
3.Position the arm correctly.
1) The air tube should run
down the inside of your
forearm and be in line with
your middle finger.
2) The bottom of the cuff
should be approximately 1
to 2 cm above your elbow.
3) Apply the cuff to your
upper arm so that the
coloured marker (blue
arrow under tube) is
centered on the middle of
your inner arm and points
down the inside of the
arm.
4.When the cuff is positioned correctly, close the fabric fastener
FIRMLY.
20
Page 21
Taking measurements on the right arm
Apply the cuff so that the air tube
is at the side of your elbow.
• Be careful not to rest your arm
on the air tube, or otherwise
restrict the flow of air to the cuff.
• The cuff should be 1 to 2 cm
above the elbow.

Taking a Reading
1.Preparation
1) Press the air release button to release any air in the arm
cuff.
2) Press the I/O button to turn the unit on.
3) All items in the display will be displayed briefly.
4) The deflation symbol will flash.
5) Finally, the heartbeat symbol will appear and 0 is
displayed.
Note: If the deflation symbol does not disappear soon, press
the air release button to release any air in the arm cuff.
2.Pump the inflation bulb to inflate the arm cuff.
1) Inflate the cuff until it is 30 to
40 mmHg above your expected
systolic blood pressure value.
ex) If your expected blood pressure is around 140mmHg,
inflate the arm cuff to between 170 and 180 mmHg. Inflate the
cuff rapidly so that the pressure is reached in about five
seconds.
2) When the desired pressure has been achieved, release
the inflation bulb. Remain still and do not talk.
22
Page 23
3.Using the Unit
Notes:
• If the reinflation symbol () appears, squeeze the inflation
bulb to re-inflate the arm cuff.
• Do not inflate the arm cuff more than necessary.
3.Measurement starts.
Measurement starts
automatically after you stop
inflating the arm cuff. Decreasing
numbers appear on the display
and the heartbeat symbol
flashes.
Remain still and do not talk
during measurement.
Note: To cancel a measurement, press the I/O button to turn
off the unit and press the air release button to release
the air in the arm cuff.
4.Measurement ends.
When the measurement is finished,
the deflation symbol flashes on the
display. Blood pressure and pulse
rate values are displayed.
Press the air release button to
release the air in the arm cuff until
the deflation symbol is no longer
displayed.

3.Using the Unit
Important:
• If your systolic or diastolic pressure is
outside the standard range, the heartbeat
symbol will blink when the measurement
result is displayed.
Recent research suggests that the
following values can be used as a guide to
high blood pressure for measurements
taken at home.
Systolic Blood PressureAbove 135 mmHg
Diastolic Blood Pressure Above 85 mmHg
This criteria is for home blood pressure measurement.
For professional office blood pressure measurement criteria,
please refer to Chapter 9 “Some Useful Information about
Blood Pressure”

feet flat on the floor and
place your arm on a
table so that the arm cuff
will be at the same level
as your heart.
2.Apply the arm cuff to your upper arm. The coloured marker
should be centred on the inside of your arm and point down
the inside of the arm, so that the air tube runs down the inside

Important information regarding Electro Magnetic Compatibility
(EMC)
With the increased number of electronic devices such as PC’s and mobile
(cellular) telephones, medical devices in use may be susceptible to
electromagnetic interference from other devices. Electromagnetic interference
may result in incorrect operation of the medical device and create a potentially
unsafe situation.
Medical devices should also not interfere with other devices.
In order to regulate the requirements for EMC (Electro Magnetic Compatibility)
with the aim to prevent unsafe product situations, the EN60601-1-2 standard
has been implemented. This standard defines the levels of immunity to
electromagnetic interferences as well as maximum levels of electromagnetic
emissions for medical devices.
This medical device manufactured by OMRON Healthcare conforms to this
EN60601-1-2:2001 standard for both immunity and emissions.
Nevertheless, special precautions need to be observed:
• Do not use mobile (cellular) telephones and other devices, which generate
strong electrical or electromagnetic fields, near the medical device. This may
result in incorrect operation of the unit and create a potentially unsafe
situation. Recommendation is to keep a minimum distance of 7 m. Verify
correct operation of the device in case the distance is shorter.
Further documentation in accordance with EN60601-1-2:2001 is available at
OMRON Healthcare Europe at the address mentioned in this instruction
manual.

9. 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.
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 itself a cause of high blood pressure. As a variety of conditions
affect blood pressure, a single measurement may not be sufficient for
an accurate diagnosis.
Many factors such as physical activity, anxiety, or the time of day, can
influence your blood pressure. 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.
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 135/85, is referred to as 135 over 85
mmHg.

Severe hypertension
Moderate hypertension

Diastolic
blood
pressure
(mmHg)
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.
