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 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 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.

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

• 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.

- Eng 2 -

mmHg

• 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.

• 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.

PRECAUTION FOR USE AND MAINTENANCE

• 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
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
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.

MEASUREMENTS

1. Attaching of Arm Cuff and Posture

During Measurement

Unfasten and open the cuff as shown in the figure.

Wind the arm cuff around the left upper arm tightly so that
bottom edge of the cuff is positioned about 1 – 2cm above
the elbow joint.

• When you will wind the cuff, please wind the cuff next to
the skin of possible.
(If measurement is made by rolling the shirts or jacket
up over the arm, this will constrict the upper arm and
prevent accurate measurement.)

• Cuff tube should be placed on the inside of your arm as
figure.

• Please make sure that the cuff is fastened tightly. Note
that uneven cuff winding will prevent proper measure­ments.

- Eng 6 -

2. Carrying out the Measurement

English Español

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, since movement - artifacts may
falsify the measuring result.
Make measurements in either a seated or reclining posture
with the palm turned upward.

Insert the air connector from the cuff into the tube socket
at the mainframe until it is tightly connected.

Press the “POWER / START” switch.

The pressure is automatically heightened to the level for
measurement of the blood pressure based on the last-mea­sured systolic blood pressure.
At the first measurement after battery replacement the pres­sure is heightened to 160mmHg.
If the level of the pressure is not enough, the pressure is
automatically heightened to the level for measurement of
the blood pressure again.

If pulse is recognized, the pressure is shifted to the dias-

When the measurement has been completed, the systolic
blood pressure, the diastolic blood pressure and the pulse
rate are alternately displayed and the air is discharged.
The systolic blood pressure and the diastolic blood pres­sure are displayed for about 2 seconds and the pulse is
displayed for about 1 second.

The measured data are registered automatically, as long as
they are not error.

When a person with maximum blood pressure of 170 mmHg
or higher uses the unit for the first time, or after changing
batteries, measure blood pressure using the manual set­ting. If the automatic pressure setting is used, it may not
work.

Automatic Pressure Setting

● This product automatically sets the pressure based on

the previous measurement, so you can easily measure
blood pressure by pressing one button without reset­ting the pressure for each measurement. If several people
use the unit, we recommend using the manual settings
as follows.

Manual Pressure Setting

● When several people use the unit, set the pressure value

manually. Please note that if the manual pressure set­ting is not used, pressure will be automatically applied
based on the value set by the previous user.
If the previous user had a high pressure setting, that
high pressure will automatically be used for the current
user. If you feel pain in your arm, press the “POWER /
START” switch immediately to turn of the power.

1. Put the arm cuff around your arm, plug the air hose
into the unit, and keep your arm at the level of your
heart.

2. Keep the “POWER / START” switch depressed until
the pressure display shows the optimal pressure set­ting. (The optimal pressure setting is about 40 mmHg
higher than your usual maximum blood pressure.)

3. When the pressure display reaches the optimal pres­sure value, release the “POWER / STAR T” switch. When
the “POWER / START” switch is released pressuriza­tion will finish and measurement will start. Manual pres­sure settings can be selected between 160 mmHg - 280
mmHg. If you release the “POWER / START” switch
before reaching 160 mmHg, the unit will pressurize to
160 mmHg. If the unit senses that the pressure is not
high enough, it will apply more pressure.

3. Turn Power OFF

Press the “POWER / START” switch to turn off.

4. Subsequent Measurement

When a measurement is need again, 10 minutes, interval
is necessary between measurements.

5. Automatic Power OFF Function

If the unit is left without any operation after measure­ment, an “Automatic Power-OFF Function” runs to turn
off the power after approximately 3 minutes. To continue
measurement, press the “POWER / START” switch again.

6. Battery Replacement

If the batteries are almost empty, the “ ” mark will be
displayed. In this case, batteries should be replaced with
new one.

Battery cover

Remove the battery cover at mainframe and replace four
type “AA” batteries.

Batteries are almost empty.

Batteries are normal.

Note: The memory data are erased when you replace the

batteries.

• The batteries that are included power the monitor. They
may not last as long as indicated.

• If manganese batteries are used at a low room tempera­ture, such as in the winter or for other reasons, the bat­teries may not function properly and you may not be able
to measure your blood pressure.

• Please dispose of used batteries properly to protect the
environmental.
