General remarks on blood pressure and measurements
1. To deflate the cuff quickly, press the “START/STOP” switch.
2. The attached cuff is suitable for wrist circumferences of 5-3/8" – 8-3/8"
(13.5-21.5 cm).
3. When attaching the cuff, the body of a blood pressure monitor should
be placed on the inside of your wrist.
4. The monitor is not intended to be a diagnostic devise, because it is
intended for home use.
5. Self measurement is not therapy! In no event should you change the
dosage of your medication prescribed by your physician.
6. As preparation for measuring your blood pressure, you should urinate
and then remain relatively still for 10 to 15 minutes prior to measurement.
7. Exercising, eating, drinking, smoking, etc., prior to measurement may
affect the results.
8. Your blood pressure varies constantly throughout the day.
Measurements should be taken regularly at the same time each day.
9. 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.
10. 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 wrist snugly. ( See page 14)
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
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.
7. DO NOT try to measure your blood pressure immediately after drinking
coffee or tea or after smoking.
GENERAL REMARKS

GENERAL REMARKS
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.
9. DO NOT measure blood pressure when the cuff has been on your
wrist for a few minutes or more. During this time, your wrist will have
built up a higher blood pressure and you will not get valid reading.
10. If the Body Movement Indicator or Irregular Hearteat (IHB) Indicator is
displayed, relax and measure your blood pressure again. If the Irregular
Heartbeat Indicator appears frequently you are advised to consult a
doctor about your health condition. ( See page 19)
11. The figure below shows the blood pressure classifications under the
WHO standards.
Remarks:
The graph is not exact, but

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 you feel abnormal pressure of the cuff during use or any other
irregularity, reduce the pressure by immediately switching off the
power or remove the batteries and consult the sales outlet where
purchased.
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 wrist.
10. DO NOT wrap the cuff around a wrist 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.

PRECAUTIONS FOR USE AND MAINTENANCE
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.
15. Be sure to use this unit only for measuring blood pressure. DO NOT
use it for any other purpose.
16. Be sure to use only our authorized parts and accessories. Parts and
accessories not approved for use with the device may damage the
unit.
17. DO NOT use this unit on infants.
18. 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 140°F (60°C)), low
temperatures (below -4°F (-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 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.
