General remarks on blood pressure and blood pressure
measurement
1. To deflate the cuff quickly, press the “START/STOP” switch.
2. The attached wide range cuff is suited for an arm circumstance of 8 3/4” – 16
1/2” (22 cm – 42 cm).
3. When attaching the cuff, adjust the position of the cuff so that the air hose is
located in the center of your arm and the hem of the cuff is 0.4” – 0.8” (1 cm –
2Űcm) above your elbow.
4. Self measurement is not therapy! In no event should you change the dosage of
your medication prescribed by your physician.
5. As preparation for measuring your blood pressure, you should urinate and then
remain relatively still for 10 to 15 minutes prior to measurement.
6. DO NOT place too much emphasis on the results of one measurement. Keep a
continuing record of your blood pressure variations. A complete picture can only
be obtained from a large number of readings.
To obtain correct blood pressure measurements
1. Take five or six deep breaths and then relax before measuring your blood
pressure. If you are tense when taking the measurement, you will not get a
valid reading.
2. Your blood pressure will be elevated if you are anxious or irritated, suffering
from lack of sleep or constipation, or have just taken some exercise or
eaten a meal.
3. Wrap the cuff around your arm and tighten it so that one finger can be
inserted between the cuff and arm. ( See page 12, 13)
4. DO NOT measure your blood pressure after bathing or drinking.
5. Measure your blood pressure where the room temperature is around 68°F
(20°C). DO NOT measure your blood pressure when it is too cold (below
50°F (10°C)) or too hot (above 104°F (40°C)) in the room.
6. DO NOT try to measure your blood pressure immediately after drinking coffee or
tea or after smoking.
7. Measure your blood pressure when you are relaxed and still. Keep the center of
the cuff at the level of your heart and DO NOT move your arm or talk.
8. DO NOT measure blood pressure when the cuff has been on your arm for a few
minutes or more. During this time, your arm will have built up a higher blood
pressure and you will not get valid reading.
9. If the Irregular Heartbeat (IHB) Indicator is displayed, relax and measure
your blood pressure again. If the Irregular Heartbeat (IHB) Indicator appears
frequently, you are advised to consult a doctor about your health condition.

10. The figure below shows the blood pressure classifications under the WHO
standards.
Remarks:
The graph is not exact, but
may be used as a guide in
understanding non-invasive
blood pressure measurements.
The device is only intended for
use by adults.
Definitions and Classifications of Blood Pressure Levels
* This unit is equipped an indicator which visually indicates the blood pressure
classification (Optimal/Normal/High-Normal/Grade 1 Hypertension/Grade 2
Hypertension/Grade 3 Hypertension) of the result after each measurement.
11. Intended Use
• This device is noninvasive blood pressure monitor by oscillometric method.
This device can measure the systolic blood pressure (SYS), the diastolic blood
pressure (DIA) and the pulse rate automatically.
• This device is intended to be used for checking personal health condition at
home under the direction of a physician and is not intended to be a diagnostic
device.
• This device is not intended for use with neonates or infant, and not intended
for automatic cycling measurement.
Measure your blood pressure at the same time each day.
* Your blood pressure changes all the time. This means that data gathered over
a long period has far more significance than data from just one measurement.
For this reason, you must measure your blood pressure on a daily basis. Ideally,
you should measure your blood pressure at the same time each day, wherever
possible.

Precautions for use
1. If you suffer from heart disease, high blood pressure or other circulatory disease,
consult your physician before using the monitor.
2. Inflating to a higher pressure may result in bruising where the cuff is applied.
If the cuff pressure feels abnormal or you experience any other irregularity while
using the cuff, reduce the pressure immediately by pressing the “START/STOP”
switch, detach the cuff or unplug the air hose connector from the monitor and
then consult the sales outlet where you purchased the monitor.
3. If you think the measurement is abnormal or if measurement makes you feel
unwell, discontinue use and consult your physician.
4. Blood pressure measurement may not be possible for anyone with a weak pulse
or arrhythmia.
5. Repeated blood pressure measurement and prolonged overinflation may cause
problems such as congestion or swelling in some people.
6. Frequently repeated blood pressure measurements will not give accurate
results. Allow an interval of about 1 minute between measurements.
7. If you suffer from a severe problem with blood circulation in your arms, consult
your physician before using the monitor. Failure to do so could be hazardous to
your health.
8. Measurement may not be possible for anyone with insufficient blood flow to the
area where measurements will be taken or who suffers from a frequent irregular
heartbeat. Consult your physician for advice on whether to use the monitor.
9. DO NOT wrap the cuff around an injured arm.
10. DO NOT wrap the cuff around an arm in which a drip (intravenous infusion)
is inserted or which is being used for blood transfusion as part of medical
treatment. Doing so could result in an injury or a serious accident.
11. Do not share the cuff with other infective person to avoid cross-infection.

■Measurement in a reclining posture
1Lie down, facing the celling.
2Lightly open your hand with palm up and straighten your arm.
3Relax your body, arm and fingers.
4Do not move your body or talk during measurement.
* Relax yourself to avoid placing
pressure on the cuff.
■You may use your right arm to measure your blood pressure.
Blood pressure value is likely to differ by as much as 10mmHg when measured on
the right arm instead of the left (or vice-versa). Measure your blood pressure on the
same arm each day.
TIPS FOR OBTAINING ACCURATE MEASUREMENTS
Your blood pressure varies according to your posture, the time of day and a range of
other factors. Ideally, you should measure your blood pressure in the same posture
at the same time every day.
■Taking measurements while sitting
* Be seated comfortably with your feet flat on the floor, and don't cross your legs.
1Place your arm on a table or similar
surface with your forearm extended.
2It is important to have the cuff level with
your heart.

ABOUT “BLOOD PRESSURE”
What is blood pressure?
The heart is a pump that
circulates blood throughout your
body. Blood is pumped from the
heart at a constant pressure into
arteries. This pressure is called
the arterial blood pressure and
represents, in general terms,
your blood pressure. Blood
pressure is indicated by several
kinds of pressures, including
the systolic pressure that occurs when the heart pumps blood, and the diastolic
pressure that occurs when blood returns to the heart.
Your blood pressure changes all the time.
Your blood pressure differs according to your age, gender and a range of other
factors. It is likely to be affected by your biorhythm during the day and by your
posture, physical activities, mental activities, level of stress and even by the air
temperature. The blood pressure of a healthy person generally varies within a day.

QWhy is the blood pressure measured at home different from that measured by the
physician or at a hospital?
A Your blood pressure may vary due to exercise, the ambient temperature or your mental
state. When you have a physician or nurse measure your blood pressure, the pressure
value is likely to be 10 to 20 mmHg higher than usual due to anxiety and/or stress.
Knowing what affects your blood pressure helps you to better monitor your health.
QWhy does the blood pressure obtained vary with measurement?
AOur blood pressure is adjusted by automatic nerve function. Blood pressure differs
with every heart beat. We are likely to think that our blood pressure is constant, but
it varies if you take measurements in repetition. Blood pressure is susceptible to the
time of day, such as morning and afternoon, season and atmospheric temperature.
In addition, blood pressure is easily affected by mental stress or emotional ups and
downs. It tends to increase when you feel tension or decrease when you are relaxed.
QWhat is the benefit of measuring my blood pressure at home?
A Blood pressure measurements taken at home give reliable data as they can be taken
when you are in a stable and relaxed condition. Physicians place considerable importance
on blood pressure measurements taken at home. You should measure your blood
pressure at the same time each day and record the variations in your blood pressure.
Always consult your physician for an interpretation of your blood pressure
readings and to determine the proper treatment.
