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 a wrist circumstance of 13.5 cm to 19.5
cm.
3. When attaching the cuff, the body of a blood pressure monitor should be
placed on the inside of your wrist.
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 your wrist snugly. (See page 14)
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 your
wrist for a few minute, as you 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.

PRECAUTION FOR USE AND MAINTENANCE
Precaution for use
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 wrist cuff around an injured wrist.
10. DO NOT wrap the wrist cuff to the wrist 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. The power of this blood pressure monitor may be shut off by electro-
static discharge from the human body. This is only a temporary
phenomenon. You can measure the blood mesaure the blood
correctly after pressing the POWER switch once again.
