• 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.

in a washing 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

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.
• 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.

other irregularity, reduce the pressure by immediately
switching off the power or removing the batteries and consult the sales outlet where purchased.

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
