GENERAL REMARKS

General remarks on blood pressure and blood pressure measurement

1. If the cuff is to be deflated quickly, depress “POWER” switch.

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 15)

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.

GENERAL REMARKS

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.

Remarks:

The graph is not exact,
but may be used as a
guide in understanding
non-invasive blood
pressure measurements.
The device intended for
use in adult population.

Definition and Classification of Blood Pressure Levels

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.

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

2. If you feel abnormal pressure of the cuff during use or any other irregularity, reduce the
pressure by immediately switching off the power or remove the batteries 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 doctor.

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 10 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 arm cuff around an injured arm.

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

16. Be sure to use only our authorized parts and accessories. Parts and accessories
not approved for use with the device may damage the unit.

17. DO NOT use this unit on infants.

18. Blood pressure measurement may not be possible for anyone with common
arrhythmias such as atrial or ventricular premature beats or atrial fi brillation.

19. The monitor is not intended to be a diagnostic device, because it is intended for
home use.

Maintenance Precautions

1. DO NOT store the blood pressure monitor in locations exposed to direct sunlight,
high temperatures (over 60°C), low temperatures (below -20°C), high relative
humidity (over 95%) or excessive amounts of dust.
Make sure to store the blood pressure monitor, where children, pets and or pests
are not there.

2. DO NOT drop the blood pressure monitor or the cuff and subject it to other
shocks or vibration.

3. Remove the batteries if the monitor will be left unused for a long period.

4. DO NOT attempt to disassemble the monitor or the cuff.

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