General remarks on blood pressure and blood pressure measurement
If the cuff is to be deflated quickly, depress “Exhaust button”.
The attached cuff is suited for an arm circumstance of 22 cm to 32 cm.
When attaching the cuff, the air hose should be placed on the inside of your arm on top of the arterial.
Self-measurement is not a therapy! In no case may you change the dosage of medication prescribed by your physician.
In preparation for blood pressure measurement, you should urinate and then remain relatively still for 10 to 15 minutes before measurement.
Exercising, eating, drinking, smoking, etc., before measurement may affect the results.
Blood pressure varies constantly throughout the day. Measurement should be made regularly at the same time each day.
DO NOT be too impressed by the results of one measurement. Keep a record of blood pressure variations. Many readings tell a story.
Emotional stress may tend to cause blood pressure to rise.
For a proper measure of blood pressure
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.
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.
Wrap the cuff around the arm and tighten it so that one finger may be inserted between the cuff and arm. (See page 12)
DO NOT measure blood pressure after bathing or drinking.
When you feel like relieving yourself, you should do so before measuring your blood pressure.
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.
DO NOT try to measure blood pressure immediately after drinking coffee or tea or smoking.
Measure blood pressure with a relaxed and quiet posture. Keep the centre of the cuff at the level of your heart, and DO NOT move your arm or talk.
DO NOT measure blood pressure after the cuff has been on for a few minutes, as your arm will have built up higher blood pressure, and you will not get a valid reading.
Measure your blood pressure at the same time daily.
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 daily. Ideally, you should measure your blood pressure daily at the same time as far as possible.
Precaution for use
If you suffer from heart disease, high blood pressure or other circulatory diseases, please consult your physician first.
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.
If you think the measured value is abnormal or if measuring makes you feel unwell, discontinue use and consult your physician.
Measurement of blood pressure may not be possible for someone with a weak pulse or arrhythmia.
If blood pressure is measured repeatedly, congestion, swelling, etc. may occur in some people.
If blood pressure is measured repeatedly, an accurate result will not be achieved. An interval of about 3 minutes should be allowed.
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.
Measurement may not be possible for someone with insufficient blood flow in the area to be measured or frequent irregular heartbeats. Consult your physician for judgment.
DO NOT wrap the cuff around an injured arm.
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.

Measurement of blood pressure may not be possible for someone with common arrhythmias such as atrial or ventricular premature beats or atrial fibrillation.
Precaution for maintenance
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.
DO NOT drop or expose the blood pressure monitor to under force or vibration.
Remove the battery/batteries when not in use for a long period.
DO NOT disassemble the apparatus.
DO NOT bend the cuff or air hose unnecessarily.
