After cleaning the cuff with a neutral detergent, lightly rinse it
with water and let it dry in the air. Hard rubbing or washing
in a washing machine will cause air leakage. Also, be careful
not to get water into the air hose.
General Remarks on blood pressure
measurement
• If the cuff is to be deflated quickly, depress “POWER” switch.
• 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-
utes prior to measurement.
• Exercise, eating and drinking, smoking, etc., prior to mea-
surement may affect the results.
• The blood pressure varies constantly throughout the day. Mea-
surement 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 worri-
some or irritated state, suffering from lack of sleep or con-
stipation, or after exercise or a meal.
• Putting on the cuff is one of the most important tasks for
ensuring proper measurement of blood pressure. Wind 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 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-
ing coffee or tea or smoking.
CLEANING METHOD OF CUFF
GENERAL REMARKS
English
- Eng 3 -

• 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.
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 re-
sult 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 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 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 pe-
riod.
• 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 to ensure proper function and performance.

Protect the nature environment:
Please help protect natural environment by respecting na-
tional and/or local recycling regulations when disposing of
the batteries and the products at the end of their useful lives.

All display marks appear for approx. 1
second and buzzer beeps.
After all display marks are disappeared,
deflation mark “▼” appears for approx.
1 second (three short beeps notify you
of ready for measurement) then the last
pressure setting value appears for
approx. 3 seconds. Then the “

Wind the arm cuff around the left upper arm tightly so that
the bottom edge of the cuff is positioned about 1-2 cm (about
1 inch) above the elbow joint.
•When you wind the cuff, please wind the cuff next to the
skin as possible. (If measurement is made by rolling the
shirts or jacket up over the arm, this will constrict the up-
per arm and prevent accurate measurement)
Rubber cuff hose should be placed on the inside of your
arm as figures.
The cuff should be wound so that one finger can be in-
serted under the cuff. Note that uneven cuff winding will
prevent proper measurements.
Rest the elbow on a table so that the section of the upper
arm is at the height of the heart. Relax the lower arm across
the table and remain still.
Make measurements in either a seated or reclining pos-
ture.

blood pressure.
There are 4 settings; 130, 160, 200 and 250mmHg.
After press on the “Pressure Setting Switch”, the set pres-
sure value will be displayed at the left and the right side of
