3. Precautions
Precision components are used in the construction of this device.
Extremes in temperature, humidity, direct sunlight, shock or dust
should be avoided.
Clean the device and cuff with a dry, soft cloth or a cloth dampened
with water and a neutral detergent. Never use alcohol, benzene,
thinner or other harsh chemicals to clean the device or cuff.
Avoid tightly folding the cuff or storing the hose tightly twisted for long
periods, as such treatment may shorten the life of the components.
The device and cuff are not water resistant. Prevent rain, sweat and
water from soiling the device and cuff.
Measurements may be distorted if the device is used close to
televisions, microwave ovens, cellular telephones, X-ray or other
devices with strong electrical fields.
When reusing the device, confirm that the device is clean.
Used equipment, parts and batteries are not treated as ordinary
household waste, and must be disposed of according to the
applicable local regulations.
When the AC adapter is used, make sure that the AC adapter can be
readily removed from the electrical outlet when necessary.
Do not modify the device. It may cause accidents or damage to the
device.
To measure blood pressure, the arm must be squeezed by the cuff hard
enough to temporarily stop blood flow through the artery. This may cause
pain, numbness or a temporary red mark to the arm. This condition will
appear especially when measurement is repeated successively. Any pain,
numbness, or red marks will disappear with time.
Take care to avoid accidental strangulation of babies or infants with
the hose.
Do not twist the air hose during measurement. This may cause injury
due to continuous cuff pressure.
Measuring blood pressure too frequently may cause harm due to
blood flow interference. Check that the operation of the device does
not result in prolonged impairment of blood circulation, when using
the device repeatedly.
If you have had a mastectomy, please consult a doctor before using
the device.
Do not let children use the device by themselves and do not use the device
in a place within the reach of infants. It may cause accidents or damage
There are small parts that may cause a choking hazard if swallowed
by mistake by infants.

release the START button to start
measurement. Then continue to
measure your blood pressure as
described on the section "7.1 Normal
Measurement".
Sit comfortably on a chair. Rest your arm on the table. Do not cross your
legs. Keep your feet on the floor and straighten your back.
Sit down in a comfortable position. Place your arm on a table with your
palm facing upward and the cuff at the same level as your heart.
Place the center of the cuff at the same level as your heart.
Relax for about five to ten minutes before measurement. If you are excited
or depressed by emotional stress, the measurement will reflect this stress
as a higher (or lower) than normal blood pressure reading and the pulse
reading will usually be faster than normal.
Remain still and keep quiet during measurement.
Do not measure immediately after physical exercise or a bath. Rest for
twenty or thirty minutes before taking the measurement.
An individual's blood pressure varies constantly, depending on what you
are doing and what you have eaten. What you drink can have a very strong
and rapid effect on your blood pressure.
This device bases its measurements on the heartbeat. If you have a very weak or
irregular heartbeat, the device may hav e difficulty determining your blood pressure.
Should the device detect a condition that is abnormal, it will stop the
measurement and display an error symbol. Refer to the section "5
Symbols" for the description of the symbols.
This device is intended for use by adults. Consult with your physician before
using this device on a child. A child should not use this device unattended.
Try to measure your blood pressure at the same time every day.

11.About Blood Pressure
What is Blood Pressure?
Blood pressure is the force exerted by blood against the walls of
the arteries. Systolic pressure occurs when the heart contracts.
Diastolic pressure occurs when the heart expands. Blood pressure
is measured in millimeters of mercury (mmHg).
12. WHO Classification Indicator
Each segment of the bar indicator corresponds to the WHO blood
pressure classification.
