GENERAL REMARKS

General Remarks on blood pressure measurement

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

• 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-

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

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.

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.
the cuff around the arm 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.

PRECAUTION FOR USE AND MAINTENANCE

• 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.

• 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.

• 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 y our
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.
