GENERAL REMARKS

General Remarks on blood pressure measurement

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

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

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

•Self measurement is no therapy! In no case may you change the dosage of medication prescribed by your physician.

•In operation for blood pressure measurement, you should urinate and should remain relatively still for 10 to 15 min-

utes prior to measurement.

•Exercise, eating and drinking, smoking, etc., prior to measurement may affect the results.

•The blood pressure varies constantly throughout the day. Measurement should be made regularly at the same time each day.

•Do NOT be 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 pressure to rise.

PRECAUTION FOR USE AND MAINTENANCE

Precautions for use

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

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

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

•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 10 minutes should be allowed.

•The memory is erased if the batteries are removed for replacement, etc. and a record should be kept of any necessary data.

Precautions 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 expose the blood pressure monitor to under force or vibration, or drop it.

•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.

•NEVER wipe the blood pressure monitor with thinner or benzene, as they may damage it.

•When the monitor is very dirty, wipe it clean with a cloth moistened with Sterilizing alcohol or a neutral detergent, and then wipe it with a dry cloth. Do NOT use thinner or benzene.
