reached, release the _START_ button

to start measurement. Then continue

to measure your blood pressure as

described on the section "7.1

Normal Measurement".

7.3.

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 have 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.

The automatic blood pressure monitor's performance may be affected by

excessive temperature or humidity, or altitude.

The device automatically stores up to thirty blood pressure and pulse

measurements in memory. Data stored in memory are assigned a data

number in the order of the newest to the oldest. The oldest data displays as

" ". The symbol in the upper left corner of the display indicates that

you are viewing previous data stored in memory.

The UA-611 and UA-651 provide a blood pressure and pulse rate

measurement even when an irregular heartbeat occurs. An

irregular heartbeat is defined as a heartbeat that varies by 25%

from the average of all heartbeats during the blood pressure

measurement. It is important that you are relaxed, remain still

and do not talk during measurements.

Note: We recommend contacting your physician if you see this

symbol frequently.

10. Pressure Bar Indicator

The indicator monitors the progress of pressure during

measurement.

11. About 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). One's

natural blood pressure is represented by the fundamental

pressure, which is measured first thing in the morning while one

is still at rest and before eating.

12. WHO Classification Indicator

Each segment of the bar indicator corresponds to the WHO blood

pressure classification.

: The indicator displays a

segment, based on the

current data,

corresponding to the

WHO classification.

body)

The device is designed for use on adults, not newborns or infants.

Environment for use. The device is for use to operate by yourself in

the home healthcare environment.

This device is designed to measure blood pressure and pulse rate

of people for diagnosis.

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

with the hose.

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

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.

Wireless communication devices, such as home networking

devices, mobile phones, cordless phones and their base stations,

walkie-talkies can affect this blood pressure monitor.

Therefore, a minimum distance of 30 cm should be kept from

such devices.

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

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.

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.

Clinical testing has not been conducted on newborn infants and

pregnant 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

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.

Do not touch the batteries, the DC jack, and the patient at the

same time. 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 compromise safety.

Should the battery short-circuit, it may become hot and

potentially cause 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.

The following are precautions for proper use of the device.

Do not apply the cuff on an arm with another medical electrical

equipment attached. The equipment may not function properly.

People who have a severe circulatory deficit in the arm must consult a

doctor before using the device, to avoid medical problems.
