Digital Blood Pressure Monitor
Model UA-651Plus
Instruction Manual Original
1W MPD4004313

The A&D blood pressure monitor is one of the most advanced
monitors available and is designed for ease of use and accuracy.
This device will facilitate your daily blood pressure regimen.

This device conforms to the European Directive 93/42 EEC for
Medical Products. This is made evident by themark ofconformity. (0123: The reference number to the involved notified
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 inthe home healthcare environment.
This device is designed to measure blood pressure and pulse rateof 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 withwater and a neutral detergent. Never use alcohol, benzene, thinner orother harsh chemicals to clean the device or cuff.
Avoid tightly folding the cuff or storing the hose tightly twisted forlong periods, as such treatment may shorten the life of thecomponents.
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 otherdevices 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 11 feet should be kept fromsuch 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 theapplicable local regulations.
Do not modify the device. It may cause accidents or damage tothe device.
To measure blood pressure, the arm must be squeezed by the
cuff hard enough to temporarily stop blood flow through theartery. This may cause pain, numbness or a temporary red markto the arm. This condition will appear especially whenmeasurement is repeated successively. Any pain, numbness, or
red marks will disappear with time.
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
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 thesame 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 andpotentially cause burns.
Allow the device to adapt to the surrounding environment beforeuse (about one hour).
Do not inflate without wrapping the cuff around the upper arm.

Apply the cuff correctly, andtake another measurement.

The battery life varies with the ambient temperature and may be shorterat low temperatures.
Generally, four new R6P batteries will last approximately for threemonths when used twice for measurement each day.
Use the specified batteries only. The batteries provided with the device
are for testing the device performance and may have a limited life.
Remove the batteries if the device is not to be used for a long time. The
batteries may leak and cause a malfunction.

1. Wrap the cuff around the upper arm, about 1 to 2 cm above the insideof the elbow, as shown.
Place the cuff directly against the skin, as clothing may cause a faintpulse and result in a measurement error.

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 with yourpalm 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 fortwenty 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 avery 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 "" 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 byexcessive 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

The UA-651Plus 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 15% from the average of all heartbeats
during the blood pressure measurement. It is important that you arerelaxed, remain still and do not talk during measurements.

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. Bloodpressure is measured in millimeters of mercury (mmHg). One's
natural blood pressure is represented by the fundamentalpressure, which is measured first thing in the morning while one
is still at rest and before eating.

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