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 a wrist circumstance of 13.5cm to

19.5cm.

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

• 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 minutes 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.

machine will cause air leakage. Also, be careful not to get water into
the air hose.

For proper measurement of blood pressure

• Take a deep breath five or six time and then relax before measuring
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.

• Putting on the cuff is one of the most important tasks for ensuring
proper measurement of blood pressure.
wrist and tighten it so that one finger may be inserted between the
cuff and arm.

• Do NOT measure blood pressure after bathing or drinking.

• When you feel like relieving yourself, you should do so before mea­suring blood pressure.

• Measure 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.

Wind the cuff around the

• Do NOT measure blood pressure immediately after drinking coffee or
tea or smoking.

• 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 during measurement.

PRECAUTION FOR USE AND MAINTENANCE

• Do NOT keep on measuring so many times, as your arm will have
built up congestion of blood, and you will not get a valid reading.

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.

Nature and frequency of maintenance:

This products is designed for use over an extended period of time; how­ever, it is generally recommended that it be inspected every two years
