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, the body of a blood
pressure monitor 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.

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

• 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.

• This Product should not be used to monitor
cardiac arrhythmia.

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 wrist.

• Do NOT measure blood pressure after bathing
or drinking.

Wind the cuff around the

• 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.

• 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.

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.

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
