General remarks on blood pressure and blood pressure
measurement
1. To deflate the cuff quickly, press the “START/STOP” switch.
2. The attached cuff is suitable for arm circumferences of 22-32 cm.
3. When attaching the cuff, adjust the position of the cuff so that the blue marker
is located in the center of your arm and the hem of the cuff is 1 to 2 cm 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. Exercising, eating, drinking, smoking, etc., prior to measurement may affect the
results.
7. Your blood pressure varies constantly throughout the day. Measurements
should be taken regularly at the same time each day.
8. 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.
9. Emotional stress tends to cause your blood pressure to rise.
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 13)
4. DO NOT measure your blood pressure after bathing or drinking.
5. If you feel the need to urinate, do so before measuring your blood pressure.
6. Measure your blood pressure where the room temperature is around 20°C. DO
NOT measure your blood pressure when it is too cold (below 10°C) or too hot
(above 40°C) in the room.
7. DO NOT try to measure your blood pressure immediately after drinking coffee or
tea or after smoking.
8. 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.
GENERAL REMARKS

- Eng 4 -
English
GENERAL REMARKS
9. 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.
10. If the Body Movement Indicator or 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. ( See page 15)
11. 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
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. 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 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 use the monitor in the vicinity of flammable gases such as those used
for anaesthesia. Doing so could ignite the gases and cause an explosion.
12. DO NOT use the monitor in enriched oxygen environments such as a hospital’s
hyperbaric chamber or oxygen tent. Doing so could ignite the oxygen and
cause a fire.
13. DO NOT use mobile phones near the monitor as this could result in a
malfunction.
14. If you use a cardiac pacemaker, consult your physician before using the monitor.

PRECAUTIONS FOR USE AND MAINTENANCE
15. Be sure to use this unit only for measuring blood pressure. DO NOT use it for
any other purpose.
16. DO NOT use this unit on infants.
17. Blood pressure measurement may not be possible for anyone with common
arrhythmias such as atrial or ventricular premature beats or atrial fibrillation.
Maintenance Precautions
1. DO NOT store the blood pressure monitor in locations exposed to direct
sunlight, high temperatures (over 60°C), low temperatures (below
-20°C), high relative humidity (over 95%) or excessive amounts of dust.
2. DO NOT drop the blood pressure monitor or subject it to other shocks or
vibration.
3. Remove the batteries if the monitor will be left unused for a long period.
4. DO NOT attempt to disassemble the monitor.
5. DO NOT bend the cuff or the air hose excessively.
6. If the monitor is very dirty, wipe it clean with a cloth moistened with sterilizing
alcohol or a neutral detergent. Then wipe it with a dry cloth.
7. NEVER clean the blood pressure monitor with thinners or benzene, as this could
damage the monitor.
8. To clean the cuff, wipe it with a moist cloth. Avoid hard rubbing, as this will
cause air leakages. Take care also not to get water into the air hose.
