GENERAL REMARKS
General remarks on blood pressure and blood pressure
measurement
English
1. To defl ate the cuff quickly, press the “START/STOP” switch.
2. The attached cuff is suitable for arm circumferences of 23-33 cm (9-13
inches).
3. When attaching the cuff, the air hose should be placed on the inside of your
arm on top of the artery.
4. Self measurement is not therapy! In no event should you change the dosage
of your medication prescribed by your physician.
5. As preparation for measuring your blood pressure, you should urinate and
then remain relatively still for 10 to 15 minutes prior to measurement.
6. Exercising, eating, drinking, smoking, etc., prior to measurement may affect
the results.
7. Your blood pressure varies constantly throughout the day. Measurements
should be taken regularly at the same time each day.
8. DO NOT place too much emphasis on the results of one measurement. Keep
a continuing record of your blood pressure variations. A complete picture can
only be obtained from a large number of readings.
9. Emotional stress tends to cause your blood pressure to rise.
To obtain correct blood pressure measurements
1. Take fi ve or six deep breaths and then relax before measuring your blood
pressure. If you are tense when taking the measurement, you will not get a
valid reading.
2. Your blood pressure will be elevated if you are anxious or irritated, suffering
from lack of sleep or constipation, or have just taken some exercise or eaten
a meal.
3. Wrap the cuff around your arm and tighten it so that one fi nger can be
inserted between the cuff and arm. (
4. DO NOT measure your blood pressure after bathing or drinking.
5. If you feel the need to urinate, do so before measuring your blood pressure.
6. Measure your blood pressure where the room temperature is around 20°C
(68°F). DO NOT measure your blood pressure when it is too cold (below
10°C/50°F) or too hot (above 40°C/104°F) in the room.
See page 14)
- Eng 2 -
GENERAL REMARKS
7. DO NOT try to measure your blood pressure immediately after drinking coffee
or tea or after smoking.
8. Measure your blood pressure when you are relaxed and still. Keep the center
of the cuff at the level of your heart and DO NOT move your arm or talk.
9. DO NOT measure blood pressure when the cuff has been on your arm for
a few minutes or more. During this time, your arm will have built up a higher
blood pressure and you will not get valid reading.
10. The fi gure below shows the blood pressure classifi cations under the WHO
standards.
Remarks:
The graph is not exact, but may be
used as a guide in understanding
non-invasive blood pressure
measurements. The device is only
intended for use with adults.
Defi nitions and Classifi cations of Blood Pressure Levels
Measure your blood pressure at the same time each day.
* Your blood pressure changes all the time. This means that data gathered over
a long period has far more signifi cance than data from just one measurement.
For this reason, you must measure your blood pressure on a daily basis. Ideally,
you should measure your blood pressure at the same time each day wherever
possible.

PRECAUTIONS FOR USE AND MAINTENANCE
Precautions for use
English
1. If you suffer from heart disease, high blood pressure or other circulatory
disease, consult your physician before using the monitor.
2. If the cuff pressure feels abnormal or you experience any other irregularity
while using the cuff, reduce the pressure immediately by pressing the
“START/STOP” switch and then consult the sales outlet where you
purchased the monitor.
3. If you think the measurement is abnormal or if measurement makes you feel
unwell, discontinue use and consult your physician.
4. Blood pressure measurement may not be possible for anyone with a weak
pulse or arrhythmia.
5. Repeated blood pressure measurement may cause problems such as
congestion or swelling in some people.
6. Frequently repeated blood pressure measurements will not give accurate
results. Allow an interval of about 3 minutes between measurements.
7. If you suffer from a severe problem with blood circulation in your arms,
consult your physician before using the monitor. Failure to do so could be
hazardous to your health.
8. Measurement may not be possible for anyone with insuffi cient blood fl ow to
the area where measurements will be taken or who suffers from a frequent
irregular heartbeat. Consult your physician for advice on whether to use the
monitor.
9. DO NOT wrap the cuff around an injured arm.
10. DO NOT wrap the cuff around an arm in which a drip (intravenous infusion)
is inserted or which is being used for blood transfusion as part of medical
treatment. Doing so could result in an injury or a serious accident.
11. DO NOT use the monitor in the vicinity of fl ammable gases such as those
used for anaesthesia. Doing so could ignite the gases and cause an
explosion.
12. DO NOT use the monitor in enriched oxygen environments such as a
hospital’s hyperbaric chamber or oxygen tent. Doing so could ignite the
oxygen and cause a fi re.
13. DO NOT use mobile phones near the monitor as this could result in a
malfunction.
14. If you use a cardiac pacemaker, consult your physician before using the
monitor.

TIPS FOR OBTAINING ACCURATE MEASUREMENTS
Your blood pressure varies according to your posture, the time of day and a
range of other factors. Ideally, you should measure your blood pressure in the
same posture at the same time every day.
■ Taking measurements while sitting
1 Place your arm on a table or similar
surface with your forearm extended.
2 It is important to have the arm cuff level
with your heart.
3 Open your hand slightly on the table
so that your palm is facing up and your
fi ngers are relaxed.
4 Do not move your body or talk while taking
the measurement.
English
- Eng 13 -
ATTACHING THE ARM CUFF
1 Unroll the arm cuff.
English
• Unroll the arm cuff and thread the end
through the metal hoop so that the
side with the Velcro patch is on the
outside.
2 Put the arm cuff around your
arm so that the air hose is to the
left of your palm.
• The arm cuff should be put directly
against your skin but can also be used
over a lightweight sleeve.
• If you are wearing a thick top, remove
it. Do not roll up your sleeve as this
may compress your upper arm and
result in incorrect measurements.
3 Adjust the position of the arm cuff so that the air hose is
located in the center of your arm and the hem of the cuff is 2
to 3 cm above your elbow.

ABOUT “BLOOD PRESSURE”
What is blood pressure?
The heart is a pump that circulates blood throughout your body. Blood is pumped
English
from the heart at a constant pressure into arteries. This pressure is called the
arterial blood pressure and represents, in general terms, your blood pressure.
Blood pressure is indicated by several kinds of pressures, including the systolic
pressure that occurs when the heart pumps blood and the diastolic pressure that
occurs when blood returns to the heart.
(Systolic)
Left atrium
Left
ventricle
Artery Artery
The artery wall expands.
Contraction
(Diastolic)
Left atrium
Left
ventricle
Normal state is restored
to the artery wall.
Dilation
Your blood pressure changes all the time.
Your blood pressure differs according to your age, gender and a range of other
factors. It is likely to be affected by your biorhythm during the day and by your
posture, physical activities, mental activities, level of stress and even by the air
temperature. The blood pressure of a healthy person generally varies by 20 to 50
mmHg within a day.

BLOOD PRESSURE Q&A
Q Why is the blood pressure measured at home different from that measured by
the physician or at a hospital?
A Your blood pressure may vary due to exercise, the ambient temperature or
your mental state. When you have a physician or nurse measure your blood
pressure, the pressure value is likely to be 10 to 20 mmHg higher than usual
due to anxiety and/or stress. Knowing what affects your blood pressure helps
you to better monitor your health.
Q What is the benefi t of measuring my blood pressure at home?
A Blood pressure measurements taken at home give reliable data as they can
be taken when you are in a stable and relaxed condition. Physicians place
considerable importance on blood pressure measurements taken at home.
You should measure your blood pressure at the same time each day and
record the variations in your blood pressure.
English
Always consult your physician for an interpretation of your blood
pressure readings and to determine the proper treatment.
