Blood pressure will be elevated when you are in a worri-
some or irritated state, suffering from lack of sleep or con-

Putting on the cuff is one of the most important tasks for
ensuring proper measurement of blood pressure.  Wind
the cuff around the ar m 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 be-
fore 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 drink-

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 con-
sult the sales outlet where purchased.

If you think the measured value is abnormal or if measur-
ing 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 re-
placement, etc. and a record should be kept of any neces-
sary data.

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.
