GENERAL REMARKS

General remarks on blood pressure and blood pressure measurement

1.	To deflate the cuff quickly, press the “START/STOP” switch.
2.	The attached cuff is suitable for wrist circumferences of 13.5-	English
	should be placed on the inside of your wrist.
	21.5 cm.
3.	When attaching the cuff, the body of a blood pressure monitor
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 five 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 wrist snugly. ( See page 14)

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. DO NOT measure your blood pressure when it is too

Definitions and Classifications 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 significance 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

1.	If you suffer from heart disease, high blood pressure or other
	circulatory disease, consult your physician before using the monitor.
2.	If you feel abnormal pressure of the cuff during use or any other	English
	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 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 1 minute 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 insufficient
	blood flow 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 wrist.

10. DO NOT wrap the cuff around a wrist 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 flammable 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 fire.

English
		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 infants.
		17. Blood pressure measurement may not be possible for anyone with
		common arrhythmias such as atrial or ventricular premature beats
		or atrial fibrillation.

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.

2.DO NOT drop the blood pressure monitor or 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.

5.DO NOT bend the cuff excessively.

6.If the monitor is very dirty, wipe it clean with a cloth moistened with sterilizing alcohol or a neutral detergent. Then wipe it with a dry cloth.

7.NEVER clean the blood pressure monitor with thinners or benzene, as this could damage the monitor.

8.To clean the cuff, wipe it with a moist cloth. Avoid hard rubbing, as this will cause air leakages.
