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.
Take care to avoid accidental strangulation of babies or infants withthe hose and cable.
Do not twist the air hose during measurement. This may cause injury
due to continuous cuff pressure.
The device and cuff are not water resistant. Prevent rain, sweat andwater 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 otherdevices with strong electrical fields.
Wireless communication devices, such as home networking devices,mobile phones, cordless phones and their base stations, walkietalkies can affect this blood pressure monitor.
Therefore, a minimum distance of 30 cm should be kept from suchdevices.
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.
Do not modify the device. It may cause accidents or damage to thedevice.
To measure blood pressure, the arm must be squeezed by the cuff
hard enough to temporarily stop blood flow through the artery. Thismay cause pain, numbness or a temporary red mark to the arm.
This condition will appear especially when measurement is repeatedsuccessively. Any pain, numbness, or red marks will disappear withtime.
Measuring blood pressure too frequently may cause harm due toblood flow interference. Check that the operation of the device does
not result in prolonged impairment of blood circulation, when using
the device repeatedly.
Clinical testing has not been conducted on newborn infants andpregnant woman. Do not use on newborn infants or pregnant woman.
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 thedevice 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 swallowedby mistake by infants.
Do not touch the batteries, the DC jack, and the patient at the sametime. That may result in electrical shock.
Unplug the AC adapter when not in use during the measurement.
Use of accessories not detailed in this manual may compromisesafety.
Should the battery short-circuit, it may become hot and potentiallycause burns.
Allow the device to adapt to the surrounding environment before use(about one hour).
Do not inflate without wrapping the cuff around the upper arm.

Contraindications

The following are precautions for proper use of the device.
T Do not apply the cuff on an arm with another medical electricalequipment attached. The equipment may not function properly.
T People who have a severe circulatory deficit in the arm must consult adoctor before using the device, to avoid medical problems.
T Do not self-diagnose the measurement results and start treatment by
yourself. Always consult your doctor for evaluation of the results andtreatment.
T Do not apply the cuff on an arm with an unhealed wound.
T Do not apply the cuff on an arm receiving an intravenous drip or bloodtransfusion. It may cause injury or accidents.
T Do not use the device where flammable gases such as anesthetic
gases are present. It may cause an explosion.
T Do not use the device in highly concentrated oxygen environments,
such as a high-pressure oxygen chamber or an oxygen tent. It may
cause a fire or explosion.

Using the correct cuff size is important for an accurate reading. If thecuff is not the proper size, the reading may yield an incorrect bloodpressure value.
The arm size is printed on each cuff.
The index  and proper fit range, on the cuff, tell you if you are
applying the correct cuff. Refer to "6.5 Applying The Arm Cuff".
If the index  points outside of the range, contact your local dealer topurchase a replacement cuff.
The arm cuff is a consumable. If it becomes worn, purchase a newone.

6.5. Applying The Arm Cuff

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). One‘s natural bloodpressure is represented by the fundamental pressure, which ismeasured first thing in the morning while one is still at rest and before
eating.

Sit comfortably on a chair. Rest your arm on the table. Do not crossyour legs. Keep your feet on the floor and straighten your back.
Sit down in a comfortable position. Place your arm on a table withyour 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 willreflect 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. Restfor 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 avery 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 have difficulty determining
your blood pressure.
Should the device detect a condition that is abnormal, it will stop themeasurement 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.
The automatic blood pressure monitor‘s performance may be affectedby excessive temperature or humidity, or altitude.

8. Recalling the Memory Data
The device automatically stores up to sixty blood pressure and pulse
measurements in memory. Data stored in memory are assigned adata number in the order of the newest to the oldest. The oldest data
displays as "". The M symbol in the upper left corner of the display
indicates that you are viewing previous data stored in memory.

8.1. Recalling Data

1. When nothing isdisplayed, press andhold the START button
to recall the stored data.
2. Release the button

1. Wrap the cuff around the upper arm, about 1 to 2 cm above theinside of the elbow, as shown. Place the cuff directly against
the skin, as clothing may cause a faint pulse and result in ameasurement error.
2. Constriction of the upper arm, caused by rolling up a shirtsleeve,
may prevent accurate readings.
3. Confirm that the index  points within the proper fit range.

Recommended Action
Set the mark on the arteryof the upper arm or in linewith the ring finger on theinside of the arm.

When the monitor detects an irregular rhythm during themeasurements, the I.H.B./AFib indicator will appear on the display
with the measurement values.
Note: W e recommend contacting your physician if you see this
I.H.B./AFib symbol frequently.
The heart contracts due to electrical signals occurring in heart andsends blood through the body. Atrial fibrillation (AFib) occurs whenthe electrical signal in the atrium becomes confused and leads todisturbances in the pulse interval. AFib can cause blood to stagnatein the heart, which can easily create clots of blood, a cause of strokeand heart attack.
