GENERAL REMARKS

General remarks on blood pressure and blood pressure
measurement

1. If the cuff is to be deflated quickly, depress “Exhaust button”.

2. The attached cuff is suited for an arm circumstance of 22 cm to 32
cm.

3. When attaching the cuff, the air hose should be placed on the inside
of your arm on top of the arterial.

4. Self measurement is not therapy! In no case may you change the
dosage of medication prescribed by your physician.

5. In preparation for blood pressure measurement, 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. Blood pressure varies constantly throughout the day. Measurement
should be made regularly at the same time each day.

8. DO NOT be too impressed by the results of one measurement. Keep
a record of blood pressure variations. Many reading tell a story.

9. Emotional stress may tend to cause blood pressure to rise.

For proper measure of blood pressure

1. Take a deep breath five or six times and then relax before measuring
your blood pressure. If you are tense when taking the measurement,
you will not get a valid reading.

2. Blood pressure will be elevated when you are in a worrisome or
irritated state, suffering from lack of sleep or constipation, or after
exercise or a meal.

3. Wrap the cuff around the arm and tighten it so that one finger may be
inserted between the cuff and arm. (See page 12)

4. DO NOT measure blood pressure after bathing or drinking.

5. When you feel like relieving yourself, you should do so before
measuring your blood pressure.

6. Measure your blood pressure where the room temperature is about
20°C. DO NOT measure blood pressure when it is too cold (below
10°C) or too hot (above 40°C) in the room.

7. DO NOT try to measure blood pressure immediately after drinking
coffee or tea or smoking.

8. Measure blood pressure with a relaxed and quiet posture. 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 after the cuff has been on for a few
minute, as your arm will have built up higher blood pressure, and you
will not get valid reading.

10.Next figure shows the classification of blood pressure according to
WHO-standard.

Measure your blood pressure at the same time on a daily basis.

* The blood pressure changes at all times. This means that data

gathered over a long period has great significance instead of data on
just one measurement. It is therefore necessary to measure your
blood pressure on a daily basis. Ideally, you should measure your
blood pressure daily at the same time as far as possible.

Precaution for use

1. If you suffer from heart disease, high blood pressure or other
circulatory disease, please consult your physician first.

2. If you feel abnormal pressure of the cuff during use or other
irregularity, reduce the pressure immediately by depressing “Exhaust
button” and consult the sales outlet where purchased.

3. If you think the measured value is abnormal or if measuring makes
you feel unwell, discontinue use and consult your physician.

4. Measurement of blood pressure may not be possible for someone
with a weak pulse or arrhythmia.

5. If blood pressure is measured repeatedly, congestion, swelling, etc.
may occur in some people.

6. If blood pressure is measured repeatedly, an accurate result will not
be achieved. An interval of about 3 minutes should be allowed.

7. Consult your physician before use if you suffer a severe disorder of
blood circulation in the arms. Failure to do so may cause health
hazards.

8. Measurement may not be possible for someone with an insufficient
blood flow in the area to be measured or frequent irregular
heartbeats. Consult your physician for judgment.

9. DO NOT wrap the cuff around an injured arm.

10.DO NOT wrap the cuff to the arm where a drip (intravenous infusion)
or blood transfusion under medical treatment. Failure to do so may
cause an injury or a serious accident.

11.DO NOT use in the vicinity of flammable gases such as anesthetic
gases because of the risk of ignition and explosion.

12.DO NOT use in enriched oxygen environments such as a hospital’s
hyperbaric chamber or oxygen tent because of the risk of ignition and
fire.

13.DO NOT use a mobile phone near the unit. Doing so may result in
malfunction.

14.If you use a cardiac pacemaker, consult your physician before use.

15.Be sure to use this unit only for measuring blood pressure. DO NOT
use it for any other purpose.

16.DO NOT use this unit on an infant.

17.This product uses natural rubber for the rubber bulb.
The natural rubber may cause any allergic reaction such as itching,
flare, urticaria, swelling, fever, difficult breathing, asthma status,
blood pressure drop or any shock.

* If any of the symptoms as shown above is observed, immediately

stop using this product and consult your physician.

18.Blood pressure measurements determined with this device are
equivalent to those obtained by a trained observer using the
cuff/stethoscope auscultation method, within the limits prescribed by
the American National Standard, Electronic or automated
sphygmomanometers.

19.Measurement of blood pressure may not be possible for someone
with a common arrhythmias such as atrial or ventricular premature
beats or atrial fibrillation.

Precaution for maintenance

1. DO NOT store the blood pressure monitor where it will be exposed to
direct sunlight, high temperature (over 60°C), low temperature (below

-20°C), high relative humidity (over 95%) or in a dusty place.

2. DO NOT drop or expose the blood pressure monitor to under force or
vibration.

3. Remove the battery/batteries when not in use for a long period.

4. DO NOT disassemble the apparatus.

5. DO NOT bend the cuff or air hose unnecessarily.

6. When the monitor is very dirty, wipe it clean with a cloth moistened
